Gegenstand der Erfindung ist ein Rückschlagventil gemäß Oberbegriff des Hauptanspruches»The subject of the invention is a check valve according to the preamble of the main claim »

Es ist bekannt, daß die Betätigung der Bremse bei Rückschlagventilen dieser Art zu stärkeren Schwingungen führt, die sich als störende Geräusche im Fahrgastraum bemerkbar machen. Versuche, die durch die Federvibration erzeugten Geräusche durch Veränderung der Federkonstante, kunststoffumhüllte Federn oder dergleichen zu dämpfen, führten nur zu unerheblichen Verbesserungen.It is known that the operation of the brake in check valves this type leads to stronger vibrations, which result as annoying noises in the passenger compartment to make noticable. Try to reduce the noise generated by the spring vibration by changing the spring constant, plastic-coated springs or the like attenuating only resulted in insignificant improvements.

Aufgabe der Erfindung ist es, Schwingungen der das Dichtelement belastenden Feder auf einfache Weise wirkungsvoll zu dämpfen, damit beim Betrieb des Bremskraftverstärkers keine störenden Geräusche auftreten.The object of the invention is to effectively and easily vibrate the spring loading the sealing element to attenuate so that no disturbing noises occur when the brake booster is in operation.

Diese Aufgabe wird erfindungsgemäß mit den im Patentanspruch 1 angegebenen Merkmalen gelöst. Die weitere Ausbildung des Erfindungsgegenstandes geht aus dem Unteranspruch hervor.This object is achieved according to the invention with the features specified in claim 1. The further development of the subject matter of the invention emerges from the subclaim.

Die Vorteile der Erfindung liegen darin, daß mit einer unkomplizierten und damit preiswerten Konstruktion ein geräuschfreies■Arbeiten des Bremskraftverstärkers erzielt wird.The advantages of the invention are that with a uncomplicated and therefore inexpensive construction, a noise-free ■ operation of the brake booster is achieved will.

Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt und wird nachstehend erläutert. Es zeigen:An embodiment of the invention is in the drawing and is explained below. Show it:

Fig. 1 einen Schnitt durch ein Rückschlagventil, Fig. 2 eine Seitenansicht eines Dichtelementen, FIg. 3 eine Draufsicht auf Fig. 2,1 shows a section through a check valve, FIG. 2 shows a side view of a sealing element, FIg. 3 is a plan view of FIG. 2,

Fig, 4 eine Draufsicht auf ein Dichtelement mit unterbrochener Ringhaut.4 shows a plan view of a sealing element with an interrupted ring skin.

Das in einem Federteller 4 des Rückschlagventils sitzende Dichtelement 1 weist eine ringförmige Haut 2 auf, die unter leichter Vorspannung an der Innenwand des Ventilgehäuses 3 anliegt.The seated in a spring plate 4 of the check valve Sealing element 1 has an annular skin 2, which is slightly pretensioned on the inner wall of the valve housing 3 is present.

Bei Bremsbetätigung wird der Federteller 4- mit der Dichtung 1 gegen die Kraft der Feder 5 angehoben, wobei die Haut 2 bzw. 2' des Dichtelementes 1 an der Innenwand des Ventilgehäuses 1 gleitet und eine Schwingungsdämpfung der Feder 5 bewirkt, so daß geräuscherzeugende Schwingungen nicht auftreten.When the brake is actuated, the spring plate is 4- with the seal 1 raised against the force of the spring 5, the skin 2 or 2 'of the sealing element 1 on the inner wall of the Valve housing 1 slides and causes a vibration damping of the spring 5, so that noise-generating vibrations do not occur.
