Definitions
- the invention relates to a jet regulator with a sleeve-shaped Housing in which a beam splitting device is arranged which is a jet regulating device in the flow direction downstream is which beam regulating device several arranged in the flow path transversely to the direction of flow Has impact body.
- a jet regulator is already known from DE-A1-30 00 799, a jet splitting device with a perforated plate which has a number for generating individual beams Has flow holes.
- the perforated plate of this previously known Jet regulators are an air intake device in the flow direction and a beam regulating device downstream, which has several jet regulating screens. These jet regulating screens each form one in the flow path transverse to the direction of flow arranged impact body.
- jet regulator for coarse-meshed Jet regulating screen is namely the constipation and Risk of calcification of these sieves due to the flow Water comparatively low.
- the regulating sieves are used in prior art jet regulators mostly made of metal, while the jet cutting device too is designed as a multi-part plastic part.
- the perforated plate serving as a jet cutting device can only be detachably attached to the aerator housing, so the jet regulating sieves before inserting the perforated plate inserted into the interior of the housing and on one of the perforated plates inner ring flange downstream in flow direction can be put on.
- the multi-part design of the known jet regulator and its manufacture made of different materials includes a not insignificant one Expenditure.
- the known and aerators made of different materials not be disposed of easily.
- a jet regulator is already known from EP-A-0 646 680, in which the perforated plate encompasses a plurality of rings Cascades are connected downstream on their the Perforated plate facing side several, against the flow direction have oriented pins as flow obstacles.
- This previously known cascade jet regulator is also Multi-part design, but can be made of plastic material alone getting produced. Since this is a known one Aerator therefore no longer has regulating sieves effectively counteracts calcification of this jet regulator. However, the complicated structure of this is disadvantageous Jet regulator and the fact that a standardized noise not always guaranteed with large liter capacities can be.
