Abstract
A cylinder for hydraulic systems, in particular for motor vehicles, includes a housing with an axial boring, in which a piston fastened to a piston rod is displaced axially in a guided manner, and one end surface of which is pressurized with hydraulic fluid, and which is guided in a sealed manner with respect to the housing. The cylinder is provided with connections for at least one pressure line, a connection to a fluid chamber and for fastening, and at least one lip seal, which lip seal is located in the housing to seal the housing with respect to the exterior surface of the piston. The piston and/or the piston rod, between the hydraulic fluid and the terminal area of the piston rod farther from the piston, is provided with a device for damping pressure surges from the hydraulic fluid. These cylinders are preferably used in hydraulically operated clutch assemblies for motor vehicles and alternatively for braking systems in motor vehicles.
