Hydraulic cylinder for control of motor vehicle clutch comprises cylindrical body containing axially sliding piston whose front surface delimits hydraulic chamber and rear surface engages piston rod

摘要

The hydraulic cylinder comprises a cylindrical body having a bottom at the front and open at the rear. A piston (21) reciprocates axially in an internal bore. A piston rod (44) has a head (42) at the front engaging the piston. The piston has a front surface delimiting a hydraulic chamber (20) and a rear surface (40) engaging the piston rod. A stop washer (54), carried by the cylinder body rear free end section (28), axially retains the piston in its pushed back position towards which it is acted upon by a spring (36).
