MASTER CYLINDER, IN PARTICULAR FOR A HYDRAULIC CLUTCH ACTUATION DEVICE IN MOTOR VEHICLES

A master cylinder (10) has a cylinder housing (12) in which a piston (14) that can be moved between a piston rest position and a piston actuation position by means of a piston rod (18) variably delimits a pressure chamber (16). The ball head in the recess lies directly against the piston in a highly...

Beschreibung
Zusammenfassung:	A master cylinder (10) has a cylinder housing (12) in which a piston (14) that can be moved between a piston rest position and a piston actuation position by means of a piston rod (18) variably delimits a pressure chamber (16). The ball head in the recess lies directly against the piston in a highly compact manner such that pressure forces (D) applied via the piston rod can be constantly transmitted directly to the piston. Furthermore, the formfitting connection is located between the undercut and the stop end of the insert part such that tensile forces (Z) applied via the piston rod reinforce the formfitting connection in a piston actuation position in order to ensure a high degree of pull-out reliability.
