Abstract

For a slave cylinder for a hydraulic disengaging system of a friction clutch of vehicles, wherein the slave cylinder has a slave cylinder housing which is arranged concentrically with a transmission input shaft, wherein a guide sleeve is arranged in a longitudinal bore of the slave cylinder housing at a radial distance in order to form a pressure chamber having the shape of a circular ring and wherein an annular piston is guided in the pressure chamber in an axially movable manner, which annular piston is provided with a seal on the pressure chamber side, failures or functional impairments due to swelling seals are reduced in that a limiting means that limits the swelling of the seal in the axial direction is arranged on the pressure chamber side of the seal. Furthermore, the seal support (30) is made of plastic, the surface of which is provided with a metal coating.
