摘要

The activating system (1) for an automobile clutch (15) comprises a cylinder (3) in which a piston (5) executes a working movement with a maximum defined working travel (29). The piston and the cylinder delimit a work chamber (11) which can be connected to a pressurized fluid supply. There is an emergency evacuation device (33) for the pressurized fluid which is released from a travel switch which follows the maximum travel path.
