Release system for hydraulic actuation of friction clutch of vehicle, has tool releasing engagement of catches with recesses, where tool is inserted into openings, which penetrate wall and run adjacent to open slot in peripheral direction

摘要

The system (2) has a housing (3) with an elongated borehole (5) for forming a pressure chamber (8) together with a guide sleeve (6). A piston (9) is axially movably guided in the chamber, and an axial angular disk (1) has an open slot arranged in a wall, and catches (22a) formed by radial molding process. The catches are bent radially inwards and are brought in locking engagement with recesses (23) of the piston in a form-fit manner. A tool for releasing the engagement of the catches is inserted into openings, which penetrate the wall and run adjacent to the slot in a peripheral direction.
