ABSTRACT:
A hydraulically actuated clutch release system for a motor vehicle friction clutch, including a piston-cylinder unit oriented concentrically to a transmission input shaft, whereby the cylinder is fastened to the transmission housing, and has the cylinder chamber for the piston between an inner and an outer cylinder shell. The piston itself is guided inside a guide element surrounded by the outer cylinder shell. The outer cylinder shell, next to the guide element, has at least one retaining member which can be brought into contact with the guide element, and through which retaining member the guide element can be secured against participation in the movement of the piston during the engagement and release of the clutch. In this case, when there is a change in the axial position of the piston caused by wear in the friction clutch, the action of the retaining member can be suppressed for a displacement of the guide element.
