Abstract
A hydraulic clutch release mechanism, particularly for use in the power train of a motor vehicle, employs a circular piston which is reciprocable in a plenum chamber between a cylindrical housing and a guide centrally located within the housing. One end portion of the piston is form-lockingly connected with a plastic seal at the plenum chamber. Such form-locking connection is provided adjacent one of two lips forming part of the seal. The one lip engages the external surface of the guide and the other lip engages the internal surface of the housing and is adjacent another form-locking connection established between the seal and an annular plastic or metallic retainer which is affixed to the piston with limited axial play. The other end portion of the piston is operatively connected with a clutch, e.g., by way of a release bearing.
