Abstract
A slave cylinder which serves to disengage the friction clutch between the output shaft of the engine and the transmission in the power train of a motor vehicle has a housing affixed to the case of the transmission and having an internal surface coaxial with and spacedly surrounding the cylindrical external surface of a hollow cylindrical guide coaxial with and surrounding the output shaft. An annular piston of the slave cylinder is reciprocable between the two cylindrical surfaces and carries a clutch release bearing at one end. The other end of the piston is adjacent an annular plenum chamber of the slave cylinder. An annular seal between an end portion of the guide at the transmission case and an adjacent annular centering portion of the housing is installed in such a way that it does not extend radially outwardly beyond the internal surface of the housing, i.e., radially of and beyond the plenum chamber.
