    摘要: A master cylinder for a hydraulically actuated clutch or brake system in a motor vehicle includes a piston in a housing, the piston being axially movable in the housing by a piston rod. The piston rod has a ball-shaped head, at least certain areas of which are surrounded by first and second shell-like support elements which form a ball socket, so that the piston and the piston rod are connected to each other essentially without play, but are still free to swivel with respect to each other. The support elements are arranged at least in part inside a piston shaft sleeve, against which these elements may be supported when forces introduced via the piston rod act upon them. The first support element has a hemispherical shell to enclose half of the ball-shaped head. The other side of the ball-shaped head, except for a certain clearance required for swiveling, is surrounded by a support element with a spherical-segment-shaped ring, through the opening in which the piston rod passes.

    摘要: A pressure cylinder for a hydraulic actuation device in motor vehicles includes a housing (1) with an internal cylinder (2,3). A piston (6) is displaceable in the internal cylinder for forming a pressure space (12) for a hydraulic fluid. The piston includes a hemispherical socket (10) in an indentation (9). A spring (18) is arranged in the pressure space (12), and a tappet (7) is connected by a transmission part with a hemispherical cap (8). The tappet (7) is in a frictional and swivelable engagement in the socket (10) in an indentation (9) by the force of the spring (18). The piston is a deep-drawn, cup-shaped part and includes a filling piece (13) in the interior of the piston (6). An annular space (15) is disposed at a piston surface (14) facing toward the pressure space (12). The annular space (15) is for receiving the spring (18) in a compressed state when the piston (6) is in a top dead center position.
