Abstract
A piston-cylinder arrangement, in particular for a clutch actuation system in a motor vehicle, including a housing () that is concentrically arranged around a shaft (), and an annular pressure chamber () inside which a piston () is movably mounted. A sealing ring support () on which a seal () is arranged is connected to the piston. In a piston-cylinder arrangement which is less expensive to produce and nevertheless reliably prevents gap extrusion of the seal between the housing and the sealing ring support, the piston is connected without play to the sealing ring support.
