Master cylinder for use in hydraulic brake- or clutch system, particularly for two-wheeler, motorcycle or bicycle, for hydraulic actuator, has cylinder housing with piston bore and piston arranged in piston bore

摘要

The master cylinder (10) has a cylinder housing (12) with a piston bore (14) and a piston (16) arranged in the piston bore. A backlash opening in the direction of the main axis of the piston has a larger diameter than in the peripheral direction of the piston. The backlash opening has a shape of a groove, which runs partially along the piston lateral area (70). The piston is made of duroplast or thermoplast.
