The cylinder has pistons each exhibiting a pressure chamber and a central valve (22), which is opened in a resting position of the piston to connect a pressure chamber with an equalization and castor connection over a piston channel. A valve body (34) is p...

The arrangement has a stopper arranged in a recess of a piston for limiting an insertion unit of an input part (6) into the recess. An axial pressing force exercised on a tappet (4) for causing snap connection is smaller than the force exercised on the tap...

The vacuum brake servo (10) for motor vehicles has a working piston (16) separating a vacuum chamber (26) from a working chamber (28) in the servo housing (24). A two-section sealing device (40) has an anchoring section (50) fastened to the housing and for...

The hydraulic cylinder has a housing with a cylinder wall for receiving a longitudinally moveable piston. The piston and the cylinder wall define a pressure chamber. The piston has a surface for a sealing element which cooperates with the piston surface in...

The overflow container (12) has a hydraulic fluid chamber (50) defined between a container base (46) and a flexible container cover (52), displaced relative to the base in dependence on the container filling level and coupled to the atmosphere via a vent c...
