StufenhauptzylinderStepped master cylinder

Die Erfindung "betrifft einen Stufenhauptzylinder, bei dem eine durch die als Rückschlagventil wirkende Dichtmanschette des Kolbens der kleinen Stufe gesteuerte Verbindung zwischen den Arbeitsräumen der beiden Stufen besteht und eine zwischen dem Arbeitsraum der großen Stufe und dem Behälter bestehende Verbindung durch ein unter dem Druck einer einstellbaren Feder stehendes Ventil gesteuert wird»The invention "relates to a stage master cylinder in which one by the sealing sleeve of the piston acting as a check valve There is a small step controlled connection between the work rooms of the two steps and one between the work room of the large one Stage and the existing connection to the container is controlled by a valve under the pressure of an adjustable spring »

Es ist bekannt, das Ventil, durch dessen einstellbare Federvorspannung der Schaltpunkt für das Einsetzen der Bremswirkung der kleinen Stufe bestimmt wird, im Kolben des Hauptzylinders unterzubringen. Es ist aber auch als Nachteil zu betrachten, daß zur Justierung des Schaltdruckes oder zur Umstellung des Hauptzylinders auf einen anderen Schaltdruck jedesmal seine vollständige Demontage vorgenommen werden muß, da man anders nicht an die Einstellschraube für die Feder herankommen kann.It is known, the valve, through its adjustable spring preload the switching point for the onset of the braking effect of the small stage is determined to be accommodated in the piston of the master cylinder. But it is also to be regarded as a disadvantage that to adjust the switching pressure or to switch the master cylinder to another Switching pressure each time its complete dismantling must be made, otherwise you can not get to the adjusting screw for the spring can.

Zur Verbesserung dieses Mißstandes wird vorgeschlagen, das unter dem Druck der einstellbaren Feder stehende Ventil von außen zugänglich in der Gehäusewand anzuordnen« Hierbei ist es von Vorteil, wenn in bekannter Weise das Ventil durch einen Stößel aushebbar ist, der in der Zylinderwand angeordnet ist und vom Druck der kleinen Stufe beaufschlagbar ist, und daß die Bohrung, die das Ventil enthält, von einer verstellbaren Kappe flüssigkeitsdicht verschlossen ist,To improve this situation it is proposed that under the Pressure of the adjustable spring to be arranged in the housing wall accessible from the outside As is known, the valve can be lifted out by a plunger which is arranged in the cylinder wall and can be acted upon by the pressure of the small step and that the bore containing the valve is closed in a liquid-tight manner by an adjustable cap,

In der Zeichnung ist eine Ausführungsform der Erfindung im Schnitt dargestellt.In the drawing, an embodiment of the invention is in section shown.

Der Zylinder 1 ist mit dem Behälter 2 zusammengebaut und mit ko-The cylinder 1 is assembled with the container 2 and

Zu der Schaltvorrichtung gehört ferner der Stößel 18 mit der Dichtung 19 und die mittels der Bachstellkappe 2o einstellbare Ventilfeder 21« In der ersten Phase der Bremsung verdrängt der Kolbän 4 der großen Stufe Druckmittel aus dem Arbeitsraum 9 durch die Bohrungen 22 im Kolben 6 der kleinen Stufe über den Rand der Lippendichtung 23 und den Arbeitsraum Io der kleinen Stufe zum Anschluß 11 der Radbremszylinder1eitung#The switching device also includes the plunger 18 with the seal 19 and the valve spring adjustable by means of the Bachstellkappe 2o 21 “The Kolbän displaces in the first braking phase 4 of the large stage pressure medium from the working chamber 9 through the bores 22 in the piston 6 of the small stage over the edge of the lip seal 23 and the working space Io of the small step to connection 11 of the wheel brake cylinder line #

Wenn nach dem Anlegen der Backen sich in der Radbremszylinderleitung und in den Arbeitsräumen 9jl° e^-n Druck aufbaut, der die durch die Einstellung der Feder 21 bedingte Höhe erreicht, hebt er die Kugel 16 von ihrem Sitz und öffnet dadurch dem Druckmittel aus dem Raum 9 den Abfluß zum Behälter 2 über die Bohrungen 13,14»15· Da der Arbeitsraum 9 nunmehr drucklos ist, wirkt die Dichtmanschette 23 als Rückschlagventil und der Einsatz der Hochdruckstufe beginnt« Zugleich wird der Stößel 18 angehoben und drückt die Ventilfeder 21 vollends zusammen»If after the application of the jaws in the Radbremszylinderleitung and in the working spaces 9JL ° e ^ - builds n pressure reaching the conditional by the setting of the spring 21 level, it lifts the ball 16 from its seat, thereby opening the pressure medium from the Space 9 the drain to container 2 via the bores 13, 14 »15 · Since the working space 9 is now depressurized, the sealing sleeve 23 acts as a check valve and the high pressure stage begins. At the same time, the plunger 18 is lifted and compresses the valve spring 21 completely »
