摘要： A sealing arrangement for providing a seal between a component and a cylinder in which the component is inserted includes a sealing ring supported in the axial direction in a circumferential slot on the component. The sealing ring has at least one static and one dynamic sealing lip. The sealing lips rest radially on corresponding sealing surfaces of the component and the cylinder. To reduce the noise generated during movement of the component in the cylinder, the geometrical shape of at least of one of the sealing lips is asymmetrical in the axial and/or radial direction with respect to a longitudinal axis of the component or a plane perpendicular to the longitudinal axis of the component, or cavities are distributed around a circumference of a base body portion of the sealing ring.

摘要： A slave cylinder of the annular cylinder type is proposed, whereof the annular piston (45) able to slide axially between an outer cylinder wall (29) and an inner cylinder wall (33) is sealed by a grooved sealing ring (53) with respect to the pressure chamber (37). In order to be able to evacuate by means of a suction pump a hydraulic actuating system for a motor vehicle friction clutch, constructed using a slave cylinder of this type, before filling with hydraulic fluid, means are provided on the annular cylinder or in addition to the sealing lips (57) on the grooved sealing ring, which increase the sealing action of the sealing lips (57) when applying a vacuum to the hydraulic pressure chamber (37). The said means may be conical surfaces (61, 63) on the cylinder walls or a conical ring engaging in an annular groove (59) of the sealing ring (53). Additional sealing beads having a cross-sectional contour in the shape of a circular sector may be formed if necessary on the grooved sealing ring.

摘要： The invention relates to a hydraulically actuable releaser with an annular piston. The supporting ring co-operating with the annular piston and the groove sealing ring co-operating with the supporting ring have, at least in their radially outer region facing one another, an encircling supporting shoulder on the supporting ring and an encircling recess on the groove sealing ring. This measure prevents the groove sealing ring from being pressed into a possible gap between supporting ring and the external wall of the housing under pressure loading.

摘要： The hydraulically operable clutch release for a motor vehicle friction clutch comprises a housing part (3) of substantially ring form and an annular piston (9) guided displaceably in sealed manner in the direction of the ring axis on the housing part (3). The annular piston (9) together with the housing part (3) forms an annular hydraulic pressure chamber (15) and comprises a stop face (29) facing axially away from the pressure chamber (15). A release bearing (19) guided both axially and radially movably on the annular piston (9) has a non-rotating race ring (23) supportable radially movably on the stop face (29) of the annular piston and a rotating race ring (21) constantly abutting in radially movable manner on a release device (37) of the friction clutch. Between the housing part (3) and the annular piston (9) there is compressed an axially acting compression spring (31) for the permanent supporting of the rotating race ring (21) on the release device (37). Between the non-rotating race ring (23) and the annular piston (9) there is supported a spring (33) which holds the stop face (29) of the annular piston (9) at a distance from the non-rotating race ring (23) against the action of the compression spring (31) when the pressure chamber (15) is relieved of pressure for the engagement of the friction clutch. The spring (33) is so dimensioned that when the pressure chamber (15) is charged with pressure for the release of the friction clutch it permits supporting of the stop face (29) on the non-rotating race ring (23).
