Description

Die Erfindung betrifft eine Federtelleranordnung für eine als Ventil dienende Kolbenmanschette, insbesondere für Kolben von Hochdruckzylindern in hydraulischen Bremseinrichtungen. Es sind lose am Kolben anliegende Manschettendichtungen bekannt, welche lediglich von einer Feder, beispielsweise von .der Kolbenrückführfeder, am Kölben gehalten werden. Diese Anordnung hat --den Nachteil, daß die Manschette den Druck der Feder unmittelbar oder über einen: Federteller aufnehmen muß. Die an. der Manschette anliegende Fläche dies Federtellers kann die als Ventil dienende Manschette in ihrer Wirkung beeinträchtigen, so daß die F'l'üssigkeit des Nachfüllbehälters nicht mehr in der Lage ist, den .die Nachfüllöffnungen ödes Kolbens schließenden Manschettenboden vom Kolben abzuheben.The invention relates to a spring plate arrangement for a valve Serving piston sleeve, especially for pistons of high pressure cylinders in hydraulic Braking devices. There are known cuff seals lying loosely on the piston, which only from a spring, for example from .the piston return spring, on the Flasks are held. This arrangement has - the disadvantage that the cuff the Pressure of the spring directly or via a: spring plate must absorb. The on. The surface of this spring plate lying against the cuff can serve as a valve The effect of the cuff is impaired, so that the liquid in the refill container is no longer able to close the .die refill openings of the piston Lift the cuff base off the piston.

Der Gegenstand der Erfindung beseitigt diese Nachteile dadurch, daß der Federteller sich am Kolben, beispielsweise an einem Ansatz des Kolbens, abstützt, so daß die Manschette nicht mit :dem Druck der Feder belastet ist. Erfindungsgemäß greift der konisch ausgebildete Federteller über die Innenlippe .der ringförmigen Manschettendichtung und hält die Mans'c'hette dadurch am Kolben fest.The object of the invention eliminates these disadvantages in that the spring plate is supported on the piston, for example on a shoulder of the piston, so that the cuff is not loaded with the pressure of the spring. According to the invention the conical spring plate engages over the inner lip of the ring-shaped one Cuff seal and thus holds the Mans'c'hette on the piston.

Der Gegenstand der Erfindung ist in beispielhafter Ausführung in. -der Abbildung im Schnitt dargestellt.The subject matter of the invention is exemplified in FIG. - the figure shown in section.

In dem Hochdruckzylinder i liegt eine als Ventil dienende ringförmige Kolbenmanschette 2 dem-Stufenkolben, 3 an, welcher mit einem Ansatz 4 durch die Manschette hindurchgreift. Der Federteller 5 der Rückführfeder 6 ist konisch ausgebildet, überdeckt die Innenlippe 7 und sitzt mit einer Kröpfung 8 auf dem ringförmigen Ansatz 4 des Kolbens auf. Der Federteller besitzt eine oder mehrere Öffnungen 9 für den Durchtritt des Druckmittels.In the high pressure cylinder i is an annular one serving as a valve Piston sleeve 2 to the stepped piston, 3, which with a shoulder 4 through the Cuff reaches through. The spring plate 5 of the return spring 6 is conical, covers the inner lip 7 and sits with a crank 8 on the annular extension 4 of the piston. The spring plate has one or more openings 9 for the Passage of the pressure medium.
