摘要

Actuating device (1) for a friction clutch comprises a cylinder (3) forming a working chamber (5) and containing a piston (7) pre-tensioned by a spring against a bearing point of the friction clutch that exerts a twisting moment on the piston. A locking device (11) arranged between the piston and the cylinder consists of a piston-side linear guiding part (13) and a cylinder-side linear guiding part (15) that move axially toward each other depending on the movement of the piston. Preferred Features: The locking device is arranged within the working chamber.
