Description

Um eine wirksame Sohaäldämpfung zu erzielen, genügt nicht allein eine Entspannung der Abgase über besondere Wegführung. Die künstlichen Widerstände sollen sich auch dem jeweiligen Druck anpassen können. Um diese Aufgabe zu lösen, sind in vorliegender Erfindung die wesentlichen Teile, welche auf Ausdehnung beansprucht werden können, aus Gummi gefertigt.To achieve effective sole cushioning, one is not enough Relaxation of the exhaust gases via special routing. The artificial resistances are supposed to can also adapt to the respective pressure. To solve this problem are in the present invention the essential parts which are claimed to be elongated can be made of rubber.

Abb. i stellt einen Schalldämpfer aus Gummi dar, in welchem Querwiderstände eingebaut sind, derart, daß bei Drucksteigerung die Gase genötigt sind den umrahmenden Gummi auszudehnen, um sich Abfluß zu schaffen. Auf diese Weise steht der Schalldämpfer mit dem Motor in einer lebendigen Verbindung, wobei auch die Geräuschbildung sieh automatisch reguliert und durch die Verwendung von Gummi eine besonders gute Dämpfung ergibt. Die Widerstände können aus- den verschiedensten Materialien bestehen, entweder -aus--Stahlkörper, Gummiklotz od. dgl.Fig. I shows a rubber silencer in which there are cross resistances are installed in such a way that when the pressure increases, the gases are required to frame the Stretching rubber to create drainage. In this way the muffler stands with the engine in a living connection, and also see the noise generation automatically regulated and particularly good cushioning thanks to the use of rubber results. The resistors can consist of a wide variety of materials, either -of - steel body, rubber block or the like.

Die Zerlegbarkeit und Schnellmontage zwecks Reinigung oder Auswechslung von Teilen ist gewährleistet durch das Zusammenklemmen oder -schrauben zweier schalenartiger Hälften; welche aus Gummi bestehen.The dismantling and quick assembly for cleaning or replacement of parts is guaranteed by clamping or screwing together two shell-like Halves; which are made of rubber.

Abb. 2 stellt eine Dampfereinrichtung dar, welche aus einer Art konisch gewickelten Gummibandes besteht, aus dessen Zwischenräumen das Gas entweichen kann und sich nach Bedarf leiser oder lauter, je nach Ausführung, ins Freie bewegt. Die Zwischenräume der SpiralÖffnung können regulierbar gehalten sein durch mechanische Hilfsmittel, z. B. aus Metall.Fig. 2 shows a steam device, which is of a kind conical wound rubber band, from the interstices of which the gas can escape and moves outside, quieter or louder, depending on the version. the Gaps between the spiral opening can be kept adjustable by mechanical means Aids, e.g. B. made of metal.

Abb. 3 zeigt ein weiteres Ausführungsbeispiel, bei welchem, die. Sghalldämpfertüte ebenfalls aus Gummi ist und nur die an sich bekannten verstellbaren, federnden Einlagen aus Metall od. dgl. a) Gummibeutel oder Tüte, b) Schlitze, c) Wendelfeder, d) Kolben.Fig. 3 shows a further embodiment in which, the. Sghall damper bag is also made of rubber and only the known adjustable, resilient inserts Made of metal or the like a) rubber bag or bag, b) slots, c) spiral spring, d) piston.
