The present invention relates to a master cylinder, in particular for a hydraulic clutch system of a motor vehicle, with a piston (12) axially movable along a longitudinal axis within a housing, which accommodates at least one sealing arrangement (14) comp...

A first slave piston (88b) and a second slave piston (88a) are disposed in tandem in series within a cylinder body (82), and the pistons are arranged so that part of the shaft section (105) of the second slave piston (88a) overlaps with the inner periphery...

A braking device includes a guide piston (103) which surrounds the outer periphery of a rod part (89a) of a second slave piston (88a), a cup seal which is mounted on the second slave piston (88a), and a seal member (103b) which is provided on the guide pis...

The piston and cylinder unit has a hydraulic fluid filled pressure chamber (13) defined by a movable piston (3) and the housing (2) of the unit and constructed so that it seals a gap (17) between two surfaces extending axially to one another, and either th...

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 servomotor has a rigid envelope that is shaped locally to form a duct (3), with a hub (5) that can slide into the duct through an aperture (30) with a seal (6) and wedging elements. The seal comprises a ring (61) of an elastomer material and an annular...
