Abstract

The invention relates to a jet regulator (1) to be connected to sanitary fixtures or the like, having a jet-separating device which has a perforated plate which exhibits a number of throughflow holes in order to produce individual jets. The jet regulator (1) according to the invention is characterised in that at least one deflection slope (6, 7) is assigned to at least some of the throughflow holes, at a distance from their outflow side, which deflection slope is arranged, at least in its sub-region against which at least one of the individual jets flows, obliquely with respect to the flow direction (Pf1), and in that flow impediments formed by spaced-apart pins (11) and/or ribs (12) are arranged downstream of said deflection slope or deflection slopes (6, 7), as seen in the direction of deflection. The jet regulator according to the invention, which can do without the otherwise conventional jet-regulating screens, is distinguished by a low amount of noise formation and the production of a uniform full jet, the overall height of the jet regulator not exceeding the conventional overall height of jet regulators of this type. <IMAGE>

Description

Die Erfindung betrifft einen Strahlregler zum Anschluß an Sanitärarmaturen oder dergleichen, mit einer Strahlzerlege-Einrichtung, die eine Lochplatte hat, welche zur Erzeugung von Einzelstrahlen eine Anzahl Durchflußlöcher aufweist.The invention relates to a jet regulator for connection Sanitary fittings or the like, with a jet cutting device, which has a perforated plate which is used to produce Single beams has a number of flow holes.

Aus der DE-PS 30 00 799 ist bereits ein Strahlregler der eingangs erwähnten Art bekannt, der zur Erzeugung von Einzelstrahlen eine Lochplatte mit einer Anzahl von Durchflußlöchern aufweist. Der Lochplatte dieses vorbekannten Strahlreglers sind in Durchflußrichtung eine Luftansaug-Einrichtung sowie danach mehrere Strahlreguliersiebe nachgeschaltet. Die Anordnung einer größeren Zahl von Strahlreguliersieben ist jedoch aufwendig. Auch wird an gute Strahlregler die Forderung gestellt, daß eine Verkalkung, insbesondere an den dafür empfindlichen Strahlreguliersieben, kleingehalten wird. Bei dem aus DE-PS 30 00 799 vorbekannten Strahlregler ist daher die Lochplatte so ausgebildet, daß diese eine gute Strahlzerteilung begünstigt und die Reguliersiebe dementsprechend grobmaschig ausgebildet werden können. Bei grobmaschigen Reguliersieben ist nämlich die Verstopfungs- und Verkalkungsgefahr dieser Siebe durch das durchströmende Wasser vergleichsweise gering.From DE-PS 30 00 799 a jet regulator is already the known type, which is used to generate Single beams a perforated plate with a number of Has flow holes. The perforated plate of this previously known Jet regulators are an air intake device in the flow direction and then several jet regulating screens downstream. The arrangement of a larger number of However, jet regulating screens are complex. Also being good Aerator demanded that calcification, especially on the sensitive jet regulators, is kept small. In the previously known from DE-PS 30 00 799 Jet regulator is therefore designed the perforated plate so that this favors good beam splitting and the regulating screens can be formed accordingly coarse-meshed. For coarse-meshed Regulating sieves are the risk of clogging and calcification these sieves through the flowing water comparatively low.

Aus der DE-B-11 46 816 ist bereits ein Strahlregler mit einer Lochplatte bekannt, deren Durchflußlöcher als nach unten offene Kammern ausgebildet sind. Die Eintrittsöffnungen dieser Durchflußlöcher werden beispielsweise mittels zahlreicher ringförmiger Ansätze bereichsweise verdeckt, so daß der Querschnitt der am oberen Ende jeder Kammer liegenden Eintrittsöffnungen kleiner ist als der Querschnitt der Kammer. Die zuströmseitig angeordneten und die Eintrittsöffnungen der Durchflußlöcher bereichsweise überdeckenden Ansätze stellen sich dem zuströmenden Wasser jedoch als Prallflächen entgegen, die eine erhebliche und an sich unerwünschte Geräuschbildung verursachen. Darüber hinaus kommt auch der in DE-B-1 146 816 vorbeschriebene Strahlregler nicht ohne eine Anzahl der am Auslaufende angeordneten Strahlreguliersiebe aus.From DE-B-11 46 816 a jet regulator with a Perforated plate known, the flow holes as open at the bottom Chambers are formed. The entry openings of these flow holes are, for example, by means of numerous ring-shaped Approaches partially covered, so that the cross section of the upper end of each chamber is smaller than the cross section of the chamber. The upstream arranged and the inlet openings of the flow holes in some areas overlapping approaches face the inflowing water as opposing baffles, which is a substantial and inherently undesirable Cause noise. Beyond that comes too the jet regulator described in DE-B-1 146 816 is not without a number of jet regulating screens arranged at the outlet end out.

Man hat auch bereits einen Strahlregler geschaffen, der eine erste und eine in Strömungsrichtung unmittelbar dahinter angeordnete zweite Lochplatte aufweist (vgl. DE-A-34 04 662). Die erste und die von ihr beabstandete zweite Lochplatte weisen jeweils Durchflußlöcher auf, die versetzt zueinander angeordnet sind. Während mittels der ersten Lochplatte die Einzelstrahlen erzeugt werden sollen, werden mittels der zweiten Lochplatte diese Einzelstrahlen in Turbulenzen versetzt,der zur Luftzumischung erforderliche Unterdruck erzeugt und die Einzelstrahlen abgebremst. Der zweiten Lochplatte sind anstelle der sonst üblichen Strahlreguliersiebe in Strömungsrichtung mehrere Ringwände nachgeordnet, die an ihrer Wandungsinnen- und Außenseite in dem den Lochplatten zugewandten Wandungsabschnitt ringstufen- oder treppenförmige Abstufungen haben. Diese Abstufungen, die in die Bahnen der von den Lochplatten erzeugten Einzelstrahlen ragen, sollen die Wasserstrahlen unter Vermischung von Luft gut zerteilen. Da dieser vorbekannte Strahlregler ohne weitere Strahlreguliersiebe auskommt, wird insoweit die Gefahr einer Verkalkung ausgeräumt.A jet regulator has also been created, the one first and one immediately behind in the direction of flow second perforated plate (see. DE-A-34 04 662). The have the first and the second perforated plate spaced from it each have flow holes that are offset from one another are. While using the first perforated plate, the individual beams are to be generated by means of the second perforated plate these individual jets are set in turbulence, for air admixture generates the required negative pressure and the individual jets slowed down. The second perforated plate are instead of the usual ones Jet regulating screens in the direction of flow several ring walls subordinate, the inside and outside of the wall in the the perforated plates facing wall section or have stepped gradations. These gradations, which in the Paths of the individual beams generated by the perforated plates protrude, the water jets are supposed to mix well with air cut up. Since this known jet regulator without further Jet regulating sieves, there is a risk of Calcification cleared out.

Der aus DE-OS 34 04 662 vorbekannte Strahlregler weist jedoch eine vergleichsweise große Bauhöhe auf, die ein besonderes Aufnahmegehäuse erforderlich macht und deshalb auch den Einsatz dieses Strahlreglers einschränken kann. Darüber hinaus erfordert die Herstellung und der Zusammenbau der beiden Lochplatten, insbesondere wenn diese jeweils mehrere versetzt zueinander angeordnete Durchflußlöcher haben, eine hohe Präzision, was mit einem nicht unerheblichen Aufwand verbunden ist. Um bei diesen Lochplatten eine möglichst geringe Geräuschentwicklung zu erzielen, müssen beispielsweise die Durchflußlöcher der ersten Lochplatte auf ihrer Zuströmseite möglichst scharfkantig ausgebildet sein, was sich mit zunehmender Standzeit der verwendeten Spritzgußformen immer schwerer verwirklichen läßt.However, the jet regulator known from DE-OS 34 04 662 has a comparatively large overall height, which is a special housing makes necessary and therefore also the use can restrict this jet regulator. It also requires the manufacture and assembly of the two perforated plates, especially if these are offset from each other arranged flow holes have a high precision, what with a not inconsiderable effort is. In order to keep the perforated plates as low as possible To achieve noise, for example Flow holes of the first perforated plate on its inflow side be formed as sharp as possible, what with increasing service life of the injection molds used more difficult to achieve.

Es besteht daher die Aufgabe, einen gegen eine Verkalkung unempfindlichen Strahlregler der eingangs erwähnten Art zu schaffen, der mit vergleichsweise geringem Aufwand herstellbar ist, die Erzeugung eines gleichmäßigen Vollstrahles bei möglichst geringer Geräuschbildung ermöglicht und dennoch die übliche Bauhöhe derartiger Strahlregler nicht übersteigt.There is therefore the task of preventing calcification insensitive jet regulator of the type mentioned at the beginning create that can be produced with comparatively little effort is, the generation of a uniform full jet allows the lowest possible noise generation and yet the The usual height of such jet regulator does not exceed.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere darin, daß wenigstens einigen der Durchflußlöcher mit Abstand zu ihrer Ausströmseite jeweils eine Abweisschräge zugeordnet ist, welche mindestens in ihrem von wenigstens einem der Einzelstrahlen angeströmten Teilbereich schräg zur Strömungsrichtung angeordnet ist und daß dieser Abweisschräge oder diesen Abweisschrägen in Abweisrichtung durch voneinander beabstandete Stifte und/oder Rippen gebildete Strömungshindernisse nachgeordnet sind.The inventive solution to this problem consists in the Jet regulators of the type mentioned at the outset, in particular in that at least some of the flow holes are spaced too a discharge slope is assigned to each of its outflow sides, which at least in their by at least one of the Partial flow towards the area obliquely to Flow direction is arranged and that this deflection slope or this rejection slope in the rejection direction through each other spaced pins and / or ribs formed Flow obstacles are subordinate.

Auch der erfindungsgemäße Strahlregler kommt zur Erzeugung der Einzelstrahlen mit nur einer Lochplatte aus. Anstelle der üblichen Strahlreguliersiebe, die gegen eine Verkalkung und Verstopfung anfällig sind, weist der erfindungsgemäße Strahlregler voneinander beabstandete sowie etwa in Längsrichtung des Strahlreglers orientierte Stifte und/oder Rippen auf. In diesen Strömungshindernissen, denen die Einzelstrahlen über Abweisschrägen zugeführt werden, können die Einzelstrahlen gut zerteilt und gegebenenfalls mit Luft durchmischt werden. Dabei wird auch eine hohe Strömungsgeschwindigkeit der Einzelstrahlen zunächst an den sie einfangenden Abweisschrägen und anschließend noch zusätzlich an den Stiften und/oder Rippen in der gewünschten Weise abgebremst, ohne daß damit eine besonders hohe Geräuschbildung verbunden wäre. Da der erfindungsgemäße Strahlregler regelmäßig nur eine Lochplatte hat, kann beispielsweise auch der mit der versetzten Anordnung von zwei Lochplatten verbundene Aufwand vermieden und der erfindungsgemäße Strahlregler mit einer vergleichsweise geringen Bauhöhe hergestellt werden.The jet regulator according to the invention is also used to generate the Single beams with only one perforated plate. Instead of usual jet regulating screens, which protect against calcification and The constipation according to the invention exhibits constipation Jet regulators spaced apart from each other and approximately in Pins and / or oriented in the longitudinal direction of the jet regulator Ribs on. In these flow obstacles, which the Single jets can be fed over the bevel the individual beams are well divided and, if necessary, with air be mixed. It also has a high Flow velocity of the individual jets first to them captive bevel and then additionally braked the pins and / or ribs in the desired manner, without being associated with a particularly high level of noise would. Since the jet regulator according to the invention regularly only one Perforated plate has, for example, the one with the offset Arrangement of two perforated plates avoided and associated effort the jet regulator according to the invention with a comparative low height can be produced.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, daß die Stifte mit einem freien Stiftende zur Lochplatte weisen und daß zumindest die freien Stiftenden der im Ausströmbereich oder in Ausströmrichtung der Durchflußlöcher angeordneten Stifte eine Abweisschräge haben. Bei dieser besonders kompakten und einfachen Ausführungsform sind die freien Stiftenden zumindest der im Ausströmbereich der Durchflußlöcher angeordneten Stifte jeweils als Abweisschräge ausgebildet. Diese an den Stiftenden vorgesehenen Abweisschrägen können beispielsweise so ausgebildet sein, daß die freien Endbereiche vorzugsweise aller Stifte sich zur Lochplatte hin verjüngen und daß diese Endbereiche vorzugsweise kegelförmig ausgebildet sind. Statt eines kegelförmigen Stiftendes ist aber beispielsweise auch eine pyramidenförmige oder halbkugelförmige Abweisschräge möglich.A preferred embodiment according to the invention provides that the pins have a free pin end to the perforated plate and that at least the free pin ends in the outflow area or pins arranged in the outflow direction of the flow holes have a bevel. With this particularly compact and simple embodiment are the free pin ends at least the pins arranged in the outflow area of the flow holes each designed as a bevel. This at the end of the pin The proposed bevel can be designed in this way, for example be that the free end areas preferably all pins taper towards the perforated plate and that these end areas preferably are conical. Instead of a conical one The endowment is, for example, also a pyramid or hemispherical bevel possible.

Zweckmäßig ist es, wenn wenigstens einige der im Ausströmbereich oder in Ausströmrichtung der Durchflußlöcher angeordneten Stifte relativ zu diesen versetzt angeordnet sind. Dabei wird eine Ausführungsform bevorzugt, bei der die Stifte relativ zu den Durchflußlöchern radial nach innen versetzt angeordnet sind. Durch die nach innen versetzte Anordnung der im Ausströmbereich der Durchflußlöcher angeordneten Stifte werden die Einzelstrahlen nach außen abgelenkt, wo sie auf die weiteren Stifte und/oder die Rippen treffen. Diese Stifte und Rippen können auf diesem äußeren ringförmigen Bereich gut plaziert und ausreichend auf Abstand gehalten werden. Dabei ist es zweckmäßig, wenn zumindest in einem Teilbereich des Strahlreglers die der Ablaufschräge oder den Ablaufschrägen nachgeordneten Stifte in unterschiedlichen Abständen zur Strahlregler-Längsachse angeordnet sind. Die Stifte bilden somit praktisch labyrinthartig zueinander angeordnete Strömungshindernisse, die die Einzelstrahlen besonders gut zerteilen und abbremsen können, um diese mit der angesaugten Luft zu durchmischen.It is useful if at least some of the outflow area or pins arranged in the outflow direction of the flow holes are offset relative to these. Doing so Preferred embodiment, in which the pins relative to the Flow holes are arranged offset radially inwards. Due to the inward arrangement of the in the outflow area The pins arranged in the flow holes become the individual jets distracted to the outside where it is on the other pens and / or the Meet ribs. These pins and ribs can be on this outer one ring-shaped area well placed and sufficiently spaced being held. It is useful if at least in one Part of the jet regulator that of the slope or the Pins arranged downstream of the taper at different intervals are arranged to the jet regulator longitudinal axis. The pencils thus form practically labyrinthine arranged to each other Flow obstacles that separate the individual jets particularly well and can slow it down so that it can suck in the air mix.

Sind die Durchflußlöcher oder zumindest ein Teil dieser Durchflußlöcher auf einem kleineren Lochkreis der Lochplatte angeordnet, so ist es zweckmäßig, wenn wenigstens einigen der Durchflußlöcher eine gemeinsame Abweisschräge zugeordnet ist. Dabei ist es vorteilhaft, wenn die gemeinsame Abweisschräge als eine der Lochplatte zugewandte Stirnseite einer insbesondere kreisförmigen und/oder konzentrischen Ringwand ausgebildet ist.Are the flow holes or at least part of these flow holes arranged on a smaller bolt circle of the perforated plate, so it is useful if at least some of the flow holes a common rejection slope is assigned. Here it is advantageous if the common rejection slope as one the face of the perforated plate, in particular a circular one and / or concentric ring wall is formed.

Überhaupt ist es vorteilhaft, wenn der Lochplatte in Strömungsrichtung zumindest eine Ringwand nachgeordnet ist, welche wenigstens in ihrem der Lochplatte zugewandten Teilbereich sich in Richtung zur Lochplatte verjüngt. Durch den verjüngten Teilbereich dieser Ringwand werden die Einzelstrahlen geführt und zusätzlich abgebremst. Dabei ist es zweckmäßig, wenn an der Außenseite zumindest einer Ringwand in deren verjüngtem Bereich Stifte vorgesehen sind und wenn zwischen der Ringwand und einer benachbarten Ringwand, der Wandungsinnenseite des Strahlreglers und/oder einem koaxial zur Strahlregler-Längsachse angeordneten Zentralkörper ein Ringkanal vorgesehen ist.In general, it is advantageous if the perforated plate is in the direction of flow is arranged at least one ring wall, which at least in their partial area facing the perforated plate Tapered towards the perforated plate. Through the tapered section the individual beams are guided and this ring wall additionally braked. It is useful if at the Outside of at least one ring wall in its tapered area Pins are provided and if between the ring wall and one adjacent ring wall, the inside of the jet regulator and / or a coaxial to the jet regulator longitudinal axis Central body an annular channel is provided.

Der erwünschte Abbrems- oder Zerteilungs- und Durchmischungseffekt bei den an der Ringwand vorbeiströmenden Einzelstrahlen läßt sich zusätzlich begünstigen, wenn zumindest eine Ringwand auf der Wandungsaußen- und/oder -innenseite wenigstens ihres der Lochplatte zugewandten Teilbereiches ringstufen- oder kaskadenförmige Abstufungen aufweist. The desired braking or dividing and mixing effect with the individual jets flowing past the ring wall can also be favored if at least one ring wall at least on the outside and / or inside of the wall Perforated plate facing partial area ring-shaped or cascade-shaped Has gradations.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, daß die Rippen an der Wandungsinnenseite des Strahlreglers und/oder an der Innenseite wenigstens einer Ringwand vorgesehen sind und sich vorzugsweise in radialer Richtung erstrecken. Die auf der Innenseite dieser Ringwand zuströmenden Einzelstrahlen werden im Bereich dieser Rippen gefangen, nochmals abgebremst, gegebenenfalls zusätzlich mit Luft durchmischt und in Strömungsrichtung weitergeleitet. Dabei kann es vorteilhaft sein, wenn die in Strömungsrichtung orientierte Schmal- oder Stirnseite zumindest eines Teils der Rippen mit Abstand vor einer benachbarten Ringwand oder vor dem Zentralkörper angeordnet ist. Dabei kann die Dicke der Rippen an den Durchmesser der an der benachbarten Ringwand vorgesehenen Stifte angepaßt sein. Ebenso wie die Stifte wirken nämlich auch die etwa ähnlich dick bemessenen Rippen als Strömungshindernisse.A preferred embodiment according to the invention provides that the ribs on the inside of the jet regulator and / or provided on the inside of at least one ring wall are and preferably extend in the radial direction. The individual rays flowing in on the inside of this ring wall are caught in the area of these ribs, braked again, if necessary additionally mixed with air and in the direction of flow forwarded. It can be advantageous if the at least in the direction of flow oriented narrow or face part of the ribs spaced from an adjacent one Ring wall or is arranged in front of the central body. It can the thickness of the ribs to the diameter of that on the adjacent one Pins provided for the ring wall. Just like the pens the ribs, which are roughly similar in thickness, also act as Flow obstacles.

Aus Herstellungsgründen kann es jedoch auch zweckmäßig sein, wenn die Rippen sowie gegebenenfalls auch damit verbundene Verbindungsstege - unabhängig vom Durchmesser der Stifte - sich in Strömungsrichtung konisch verjüngen.For manufacturing reasons, however, it can also be useful if the ribs and, if applicable, also connecting webs connected to them - regardless of the diameter of the pins - in Taper the flow direction.

Um den Außenmantel des Strahlreglers mit den im Inneren befindlichen Ringwänden auf einfache Weise einstückig verbinden zu können, ist es zweckmäßig, wenn zumindest einige der Rippen in Strömungsrichtung mit Verbindungsstegen verbunden sind, welche die Wandungsinnenseite des Strahlreglers oder einer Ringwand mit einer gegenüberliegenden Ringwand oder dem Zentralkörper verbindet. Dabei ist es vorteilhaft, wenn die Verbindungsstege radial angeordnet sind.Around the outer jacket of the jet regulator with the ones inside To be able to connect ring walls in one piece in a simple manner, it is useful if at least some of the ribs are in Flow direction are connected with connecting webs, which the inside of the jet regulator or a ring wall connects an opposite ring wall or the central body. It is advantageous if the connecting webs are radial are arranged.

Die Erzeugung eines nach dem Durchströmen des Strahlreglers homogenen Vollstrahles wird zusätzlich begünstigt, wenn die Rippen oder die Verbindungsstege auf ihrer der Strömungsrichtung abgewandten Schmalseite randseitig abgerundet sind. Aus dem gleichen Grunde kann es zweckmäßig sein, wenn die Lochplatte ein zentrales Durchflußloch aufweist. Um dieses zentrale Durchflußloch können kreisförmig und insbesondere konzentrisch weitere Durchflußlöcher angeordnet sein.The generation of one after flowing through the jet regulator homogeneous full jet is additionally favored if the Ribs or the connecting webs on their the flow direction facing narrow side are rounded on the edge. From the for the same reason it can be useful if the perforated plate has central flow hole. Around this central flow hole can be circular and in particular concentric Flow holes may be arranged.

Um die mit der Erzeugung der Einzel strahlen mittels der Lochplatte verbundene Geräuschentwicklung möglichst gering zu halten, ist es zweckmäßig, wenn die Durchflußlöcher der Lochplatte zuströmseitig abgerundet sind und/oder sich in Strömungsrichtung trichterförmig verjüngen. Dabei hat sich ein Rundungsradius von zumindest 0,2 mm, vorzugsweise von mindestens 0,6 bis 0,8 mm, als besonders vorteilhaft erwiesen. Durch diese Abrundung des zuströmseitigen Randbereiches der Durchflußlöcher wird eine laminare Strahlführung der Einzelstrahlen erreicht, die es erlaubt, daß die Durchflußlöcher der Lochplatte auch abströmseitig einen abgerundeten Randbereich aufweisen. Durch diese beidseits abgerundeten Durchflußlöcher läßt sich ein Herstellungsaufwand vermeiden, der andernfalls mit der meist nur bei vergleichsweise kurzen Standzeiten der Spritzgußformen erreichbaren scharfkantigen Ausgestaltung dieser Durchflußlöcher verbunden wäre.To radiate with the generation of the individual by means of the perforated plate keep the associated noise level as low as possible, it is appropriate if the flow holes of the perforated plate on the inflow side are rounded and / or in the direction of flow Taper in a funnel shape. There is a rounding radius of at least 0.2 mm, preferably from at least 0.6 to 0.8 mm, as proven particularly advantageous. By rounding off the upstream side The edge area of the flow holes becomes laminar Beam guidance of the individual beams achieved, which allows that the flow holes of the perforated plate also on the downstream side have rounded edges. By this rounded on both sides Flow holes can be avoided, the otherwise with the mostly only with comparative short service life of the injection molds achievable sharp-edged Design of these flow holes would be connected.

Um eine gute Strahlzerlegung auch der Einzelstrahlen zu erzielen, wird eine möglichst dünnwandige Ausgestaltung der Lochplatte angestrebt. Unter dem Druck des auf die Lochplatte aufprallenden Wasserstrahles und insbesondere bei hohen Wassertemperaturen kann vor allem eine dünnwandige Lochplatte in Schwingungen versetzt werden und dadurch zu einer unerwünschten Geräuschbildung neigen. Eine Weiterbildung gemäß der Erfindung sieht daher vor, daß die Lochplatte insbesondere in radialer Richtung orientierte Verstärkungsrippen aufweist. Dabei ist es vorteilhaft, wenn diese Verstärkungsrippen auf der abströmseitigen Flachseite der Lochplatte vorgesehen sind.In order to achieve good beam splitting of the individual beams, is a thin-walled design of the perforated plate sought. Under the pressure of the one hitting the perforated plate Water jet and especially at high water temperatures can especially a thin-walled perforated plate vibrated become and tend to undesirable noise. A development according to the invention therefore provides that the Perforated plate, in particular reinforcing ribs oriented in the radial direction having. It is advantageous if this Reinforcing ribs on the downstream flat side of the perforated plate are provided.

Die sich in Strömungsrichtung an die Lochplatte anschließende Luftzumischungszone kann besonders groß ausgestaltet werden, wenn die Lochplatte einen tellerförmigen Längsschnitt aufweist, wobei der Boden dieser Tellerform auf der der Zuströmseite der Lochplatte angeordnet sein sollte.The one adjoining the perforated plate in the direction of flow Air admixing zone can be made particularly large if the perforated plate has a plate-shaped longitudinal section, wherein the bottom of this plate shape on the inflow side of the perforated plate should be arranged.

In Figur 1 ist ein Strahlregler 1 zum Anschluß an Sanitärarmaturen oder dergleichen in einem Teil-Längsschnitt dargestellt. Der Strahlregler 1 weist nur eine - in Figur 1 nicht dargestellte - Lochplatte 2 (vgl. Figur 4 bis 8) auf, die als Strahlzerlege-Einrichtung dient. Die Lochplatte 2, der in Strömungsrichtung ein - hier nicht dargestelltes - Vorsatzsieb vorgeschaltet sein kann, weist zur Erzeugung von Einzelstrahlen eine Anzahl von Durchflußlöchern 3 auf, die in zwei voneinander beabstandeten konzentrischen Lochkreisen 4, 5 um ein zentrales koaxiales Durchflußloch 3' angeordnet sind. Die Durchflußlöcher weisen hier einen runden lichten Querschnitt auf, können aber zumindest bereichsweise auch einen viereckigen, sechseckigen oder dergleichen mehreckigen Querschnitt haben. In Figure 1, a jet regulator 1 is connected to Sanitary fittings or the like in a partial longitudinal section shown. The jet regulator 1 has only one - in Figure 1 not shown - perforated plate 2 (see FIG. 4 to 8), which serves as a beam splitting device. The perforated plate 2, the in the direction of flow a - not shown here - Can be connected upstream, has to generate Individual jets a number of flow holes 3, which in two spaced apart concentric bolt circles 4, 5 are arranged around a central coaxial flow hole 3 '. The flow holes here have a round clear Cross-section, but can also at least in some areas a square, hexagonal or the like polygonal Cross section.

Den auf den beiden Lochkreisen 4, 5 angeordneten Durchflußlöchern sind mit Abstand zu ihrer Ausströmseite Abweisschrägen 6, 7 zugeordnet, welche mindestens in ihrem von wenigstens einem der Einzelstrahlen angeströmten Teilbereich schräg zur Strömungsrichtung Pf1 angeordnet sind und die von ihnen eingefangenen Einzelstrahlen seitlich nach außen ablenken.The arranged on the two bolt circles 4, 5 Flow holes are at a distance from their outflow side Refusal slopes 6, 7 assigned, which at least in their from at least one of the sub-areas flowing onto the individual jets are arranged obliquely to the flow direction Pf1 and that of individual rays captured to them laterally outwards distract.

Durch diese Abweisschrägen 6, 7 erfolgt eine erste Abbremsung der Wasserstrahlen, die sich mit der Luft durchmischen, welche in den zwischen den Abweisschrägen 6, 7 und der Lochplatte 2 verbleibenden und als Luftzumischzone dienenden Freiraum einströmt. Diese Luft wird von den Flüssigkeitsstrahlen über Lufteintrittsöffnungen 8 angesaugt, welche am Außenmantel 9 des Strahlreglers 1 als seitliche Durchbrechungen vorgesehen sind.A first braking takes place through these deflection slopes 6, 7 the water jets that mix with the air, which in between the bevels 6, 7 and the perforated plate 2 remaining free space serving as an air admixing zone flows in. This air is overflowed by the liquid jets Air inlet openings 8 sucked, which on the outer jacket 9th of the jet regulator 1 is provided as lateral openings are.

Die in den Figuren 4 bis 8 dargestellte Lochplatte 2 wird quer zur Strömungsrichtung Pf1 im Bereich 10 des Strahlreglers 1 quer zur Strömungsrichtung in dessen Außenmantel 9 eingepaßt.The perforated plate 2 shown in Figures 4 to 8 is transverse to flow direction Pf1 in area 10 of jet regulator 1 fitted transversely to the direction of flow in its outer jacket 9.

Den Abweisschrägen 6, 7 sind in seitlicher Abweisrichtung jeweils voneinander beabstandete und etwa in Längsrichtung des Strahlreglers 1 orientierte Stifte 11 und Rippen 12 nachgeordnet, die als Strömungshindernisse dienen und eine zusätzliche Abbremsung, Aufspaltung und Luftdurchmischung der Wasserstrahlen bewirken. Diese Stifte 11 weisen mit ihrem freien Stiftende zur Lochplatte 2, wobei diese freien Stiftenden jeweils etwa kegelförmig ausgebildet sind. Möglich wäre aber auch jeweils eine kugelförmige oder dergleichen, sich zur Lochplatte 2 hin verjüngende Formgebung der Stiftenden. The deflection slopes 6, 7 are in the lateral direction of deflection each spaced apart and approximately in the longitudinal direction of the Jet regulator 1-oriented pins 11 and ribs 12 subordinate, which serve as flow obstacles and a additional braking, splitting and air mixing of the Cause water jets. These pins 11 have their free pin end to the perforated plate 2, these free Pin ends are each approximately conical. Possible but would also be spherical or the like, the tapered shape towards the perforated plate 2 Donor ends.

Wie Figur 1 zeigt, dienen die kegelförmigen Stiftenden der dem äußeren Lochkreis 5 der Lochplatte 2 zugeordneten und in Ausströmrichtung dieser Durchflußlöcher 3 angeordneten Stifte jeweils als Abweisschrägen 6, die die auftreffenden und vom Lochkreis 5 erzeugten Einzelstrahlen zu den benachbarten äußeren Stiften 11 ablenken. Um die Einzelstrahlen jeweils nach außen ablenken zu können, sind die dem äußeren Lochkreis 5 zugeordneten und in Ausströmrichtung angeordneten Stifte 11 relativ zur Durchtrittsachse der Durchflußlöcher 3 radial nach innen versetzt angeordnet. Die Einzelstrahlen treffen somit nicht auf den Spitzen dieser Stifte 11 auf, sondern auf der nach außen weisenden Mantelfläche des jeweils kegelförmigen Stiftendes.As shown in Figure 1, the tapered pin ends serve the outer bolt circle 5 assigned to the perforated plate 2 and in Outflow direction of these flow holes 3 arranged pins each as a bevel 6, which the impinging and from Bolt circle 5 generated individual beams to the neighboring ones deflect the outer pins 11. To the individual rays each To be able to distract to the outside are those of the outer bolt circle 5 assigned pins 11 arranged in the outflow direction radially relative to the passage axis of the flow holes 3 staggered inside. The individual rays thus hit not on the tips of these pins 11, but on the outwardly facing surface of the respective conical Foundation.

Die dem äußeren Lochkreis 5 der Lochplatte 2 zugeordneten Stifte 11 sind auf drei Stiftkreisen angeordnet, wobei der innere Stiftkreis im Ausströmbereich der betreffenden Durchflußlöcher 3 des Lochkreises 5 angeordnet ist. Die auf den beiden benachbarten äußeren Stiftkreisen angeordnete Stifte 11 sind dazu versetzt zueinander angeordnet, so daß die Einzelstrahlen praktisch labyrinthartig durch die Stiftreihen geführt, aufgeteilt, stark abgebremst und mit Luft durchmischt werden.The assigned to the outer bolt circle 5 of the perforated plate 2 Pins 11 are arranged on three pin circles, the inner pin circle in the outflow area of the concerned Flow holes 3 of the bolt circle 5 is arranged. The on the two adjacent outer pin circles Pins 11 are arranged offset to each other so that the Single beams practically labyrinthine through the rows of pins led, divided, slowed down and mixed with air become.

Den auf dem inneren Lochkreis 4 angeordneten Durchflußlöchern 3 ist die gemeinsame Abweisschräge 7 zugeordnet, die durch die nach außen abgeschrägte und der Lochplatte 2 zugewandte Stirnseite einer kreisförmig konzentrischen inneren Ringwand 13 gebildet wird. Zwischen dieser inneren Ringwand 13 und dem Außenmantel 9 des Strahlreglers 1 ist eine äußere Ringwand 14 angeordnet. Während zwischen der inneren Ringwand 13 und der äußeren Ringwand 14 die der Abweisschräge 7 nachgeordneten und in nur einem Stiftkreis angeordneten Stifte 11 vorgesehen sind, schließen die äußere Ringwand 14 und der benachbarte Außenmantel 9 des Strahlreglers 1 die dem äußeren Lochkreis 5 zugeordneten Stifte 11 zwischen sich ein. Dabei ist zwischen dem Außenmantel 9 und der äußeren Ringwand 14, zwischen der äußeren und der inneren Ringwand 14, 13 und auch zwischen der inneren Ringwand 13 und einem koaxial zur Strahlregler-Längsachse angeordneten Zentralkörper 20 jeweils ein von den Wasserstrahlen durchströmter Ringkanal 15, 16 und 17 vorgesehen.The flow holes arranged on the inner hole circle 4 3 is assigned the common rejection slope 7, which by the bevelled to the outside and facing the perforated plate 2 Face of a circular concentric inner ring wall 13 is formed. Between this inner ring wall 13 and the Outer jacket 9 of the jet regulator 1 is an outer ring wall 14 arranged. While between the inner ring wall 13 and the outer ring wall 14 downstream of the deflection 7 and pins 11 arranged in only one pin circle are, the outer ring wall 14 and the adjacent close Outer jacket 9 of the jet regulator 1 which is the outer bolt circle 5 assigned pins 11 between them. It is between the outer jacket 9 and the outer ring wall 14, between the outer and inner ring walls 14, 13 and also between the inner ring wall 13 and one coaxial to the jet regulator longitudinal axis arranged central body 20 each one of the Ring channels 15, 16 and 17 through which water jets flow intended.

Ebenso wie die freien Stiftenden aller Stifte 11 des Strahlreglers 1, weist auch die Abweisschräge 7 einen Neigungswinkel von etwa 40° gegenüber der Strahlregler-Längsachse auf, so daß die von dem inneren Lochkreis 4 erzeugten Einzelstrahlen zu dem nachgeordneten Stiftkreis abgelenkt, abgebremst sowie mit Luft durchmischt werden.Just like the free pin ends of all pins 11 of the Jet regulator 1 also has a deflection slope 7 Inclination angle of approximately 40 ° with respect to the longitudinal axis of the aerator on so that the inner bolt circle 4 generated individual beams to the subordinate pin circle distracted, braked and mixed with air.

Um eine Abbremsung der Einzelstrahlen zu begünstigen und um eine gute Durchmischung dieser Flüssigkeitsstrahlen mit der angesaugten Luft zu erzielen, sind die Ringwände 13, 14 in ihrem der Lochplatte 2 zugewandten Teilbereich ringstufen- oder kaskadenförmig ausgebildet, wobei die Stufen dieser Abstufungen jeweils in einer etwa quer zur Strömungsrichtung angeordneten Ebene und die die Stufen miteinander verbindenden Axialflächen der Ringwände 13, 14 etwa in Strömungsrichtung angeordnet sind. Die in die Ringkanäle 15, 16 ragenden Kanten zwischen den Stufen und den angrenzenden Axialflächen an den Außenseiten der Ringwände 13, 14 sind scharfkantig ausgebildet, so daß eine Zerteilung und Luftdurchmischung der Einzelstrahlen begünstigt wird. Wie Figur 2 zeigt, sind auf den Ringstufen der Abstufungen, die im Vergleich zur radialen Erstreckung der angrenzenden Axialflächen kleiner sind, jeweils die Stifte 11 vorgesehen.To encourage braking of the individual jets and to a good mixing of these liquid jets with the To achieve sucked air, the ring walls 13, 14 in their partial area facing the perforated plate 2 or cascaded, the steps of this Gradations each in an approximately transverse to the flow direction arranged level and the connecting the stages Axial surfaces of the ring walls 13, 14 approximately in the direction of flow are arranged. The edges protruding into the ring channels 15, 16 between the steps and the adjacent axial surfaces on the Outside of the ring walls 13, 14 are sharp-edged trained so that a breakdown and air mixing of the Single rays is favored. As Figure 2 shows, are on the ring steps of the gradations compared to the radial Extent of the adjacent axial surfaces are smaller, each provided the pins 11.

An der Wandungsinnenseite des Strahlregler-Außenmantels 9 und an der Innenseite der beiden Ringwände 13, 14 sind die in Längsrichtung orientierten und - ebenso wie die Stifte 11 - als Strömungshindernisse dienenden Rippen 12 vorgesehen, die sich etwa in radialer Richtung erstrecken. Zumindest die Schmal- oder Stirnseiten 18 der Rippen 12 enden jeweils mit Abstand von der benachbarten Ringwand 13, 14. Dabei ist - wie Figur 1 zeigt - die Dicke der Rippen 12 an den Durchmesser der nach innen angrenzenden Ringwand 13, 14 vorgesehenen Stifte 11 angepaßt. Beispielsweise entspricht die Dicke der in den Ringkanal 16 ragenden Rippen 12 etwa dem Durchmesser der in diesem Ringkanal 16 befindlichen Stifte 11. Aus Fertigungsgründen kann es jedoch auch vorteilhaft sein, daß sich die Rippen 12 und Stege 19 unabhängig vom Stiftdurchmesser über ihre gesamte Längserstreckung zur Abströmseite hin konisch verjüngen, so wie dies in Figur 9 dargestellt ist.On the inside of the aerator outer jacket 9 and on the inside of the two ring walls 13, 14 are in Oriented in the longitudinal direction and - like the pins 11 - provided as flow obstacles ribs 12, the extend approximately in the radial direction. At least that Narrow or end faces 18 of the ribs 12 each end with Distance from the adjacent ring wall 13, 14. Here is - how Figure 1 shows - the thickness of the ribs 12 to the diameter of the pins 11 provided inward adjacent ring wall 13, 14 customized. For example, the thickness corresponds to that in the Ring channel 16 projecting ribs 12 approximately the diameter of the in this ring channel 16 located pins 11. From Manufacturing reasons, it can also be advantageous that the ribs 12 and webs 19 regardless of Pin diameter over its entire length Taper conically on the outflow side, as shown in FIG. 9 is shown.

Alle Rippen 12 können in Strömungsrichtung mit radialen Verbindungsstegen 19 verbunden sein, welche die Wandungsinnenseite des Strahlregler-Außenmantels 9 mit der Ringwand 14 oder diese Ringwand 14 mit der benachbarten Ringwand 13 und diese Ringwand 13 mit dem Zentralkörper 20 verbindet. Diese Verbindungsstege 19 sind auf ihrer der Strömungsrichtung abgewandten Schmalseite randseitig abgerundet, was eine Zusammenführung der Einzelstrahlen sowie ein harmonisches Gesamtbild des aus dem Strahlregler 1 ausströmenden Vollstrahles begünstigt. Um die Einzelstrahlen zusätzlich abbremsen zu können, können - wie Figur 9 zeigt - zwischen den Rippen 12 und Verbindungsstegen 19 weitere Rippen auf der Innenseite der Ringwände 13, 14 und/oder dem Außenmantel 9 vorgesehen sein, wobei diese zusätzlichen Rippen mit Abstand vor der benachbarten Ringwand und gegebenenfalls dem Zentralkörper enden.All ribs 12 can be radial in the direction of flow Connecting webs 19, which the Wall inside of the aerator outer jacket 9 with the Ring wall 14 or this ring wall 14 with the adjacent one Ring wall 13 and this ring wall 13 with the central body 20th connects. These connecting webs 19 are on their Narrow side facing away from the flow direction rounded off what a merger of the individual rays as well a harmonious overall picture of the aerator 1 escaping full jet favors. To the single rays to be able to brake additionally, can - as Figure 9 shows - 19 further ribs between the ribs 12 and connecting webs on the inside of the ring walls 13, 14 and / or the Outer jacket 9 may be provided, these additional ribs at a distance from the adjacent ring wall and, if necessary end the central body.

Aus Figur 3 wird deutlich, daß die zwischen den einzelnen Wandungen vorgesehenen Rippen 12 und Verbindungsstege 19 gleichmäßig über den Umfang der Ringkanäle 15, 16 und 17 verteilt und versetzt zueinander angeordnet sind. In Figur 3 ist erkennbar, daß die Ringwände 13, 14 auch an ihren Ringwand-Innenseiten ringstufen- oder kaskadenförmige Abstufungen haben. Diese sich in Strömungsrichtung erweiternden Abstufungen auf den Ringwand-Innenseiten sollen ein ungünstiges Rückfließen einzelner Flüssigkeitsstrahlen entgegen der Strömungsrichtung Pf1 verhindern.From Figure 3 it is clear that the between the individual Ribs 12 and connecting webs 19 provided on the walls evenly over the circumference of the ring channels 15, 16 and 17 are distributed and staggered. In Figure 3 can be seen that the ring walls 13, 14 also on their Ring wall insides in the form of steps or cascades Have gradations. This is in the direction of flow expanding gradations on the inside of the ring wall an unfavorable backflow of individual liquid jets prevent against the direction of flow Pf1.

Wie aus Figur 1 und 2 deutlich wird, ist dem zentralen Durchflußloch 3' der Lochplatte 2 ein koaxial angeordneter Stift 11 auf dem Zentralkörper 20 zugeordnet, dessen freies, der Lochplatte 2 zugewandtes und ebenfalls kegelförmiges Stiftende als Abweisschräge ausgebildet ist. Von diesem zentralen Stift 11 sind drei weitere Stifte 11 geringfügig beabstandet, die ebenfalls als Strömungshindernisse dienen. Diese drei äußeren Stifte überragen den zentralen Stift 11, um den aufgeteilten zentralen Einzelstrahl zu fassen.As is clear from Figures 1 and 2, the central Flow hole 3 'of the perforated plate 2 a coaxially arranged Assigned pin 11 on the central body 20, the free, the perforated plate 2 facing and also conical End of the pin is designed as a bevel. Of this central pin 11, three other pins 11 are minor spaced, which also serve as flow obstacles. These three outer pins protrude from the central pin 11 to to capture the split central single beam.

Statt der Stifte 11 kann der Zentralkörper 20 zumindest in seinem der Lochplatte 2 zugewandten Teilbereich sich außenseitig zur Lochplatte 2 hin verjüngen. Um auch dem zentralen Einzelstrahl eine hohe Strömungsgeschwindigkeit zu nehmen, kann es dabei zweckmäßig sein, wenn auch der Zentralkörper 20 zumindest in seinem der Lochplatte 2 zugewandten Teilbereich kegelförmig ausgebildet ist oder - ähnlich wie die Ringwände 13, 14 - ringstufen- oder kaskadenförmige Abstufungen aufweist. Der Zentralkörper kann aber auch seinerseits mehrere Durchflußlöcher haben, um den zentralen Einzelstrahl zusätzlich aufzuteilen.Instead of the pins 11, the central body 20 can at least in its the area facing the perforated plate 2 itself Taper on the outside towards perforated plate 2. To that too central single jet to a high flow rate take, it may be appropriate, even if the Central body 20 at least in its perforated plate 2 facing portion is conical or - similar to the ring walls 13, 14 - ring steps or has cascaded gradations. The central body can but also have several flow holes around which to split the central single jet additionally.

Aus den Längsschnitten in Figur 5 und 6 wird deutlich, daß die Lochplatte tellerförmig ausgebildet ist, wobei der Boden dieser Tellerform entgegen der Strömungsrichtung Pf1 angeordnet ist. Auf ihrer abströmseitigen Flachseite weist die Lochplatte 2 in radialer Richtung orientierte Verstärkungsrippen 21 auf, die auch eine dünnwandige Ausgestaltung der Lochplatte 2 erlauben, ohne daß diese unter dem Druck des Wasserstrahls in übermäßige Schwingungen versetzt wird. Um die mit der Erzeugung der Einzelstrahlen verbundene Geräuschbildung möglichst gering zu halten, sind - wie aus Figur 8 deutlich wird - die Durchflußlöcher 3 der Lochplatte 2 zuströmseitig abgerundet und verjüngen sich in Strömungsrichtung Pf1 trichterförmig. Dabei hat sich an diesem zuströmseitigen Randbereich der Durchflußlöcher 3 ein Rundungsradius von etwa 0,6 bis 0,8 mm als zweckmäßig erwiesen. Durch den gerundeten Randbereich der Durchflußlöcher 3 werden die Einzelstrahlen in einem laminaren Strahl ohne größere Turbulenzen geführt. Diese laminare Strahlführung erlaubt es auch, den abströmseitigen Randbereich der Durchflußlöcher 3 ebenfalls geringfügig gerundet auszubilden. Die gerundeten Ränder an den Durchflußlöchern 3 begünstigen die einfache Herstellung des Strahlreglers 1 und seiner Lochplatte 2 sowie lange Standzeiten der verwendeten Spritzgußformen.From the longitudinal sections in Figures 5 and 6 it is clear that the Perforated plate is plate-shaped, the bottom this plate shape against the flow direction Pf1 is arranged.
