Cylindrical hydraulic control device for clutch of motor vehicle, has metallic elastic washer with anti-vibrating function and supported against inner ring of rolling bearing and circular piston to isolate bearing from piston vibrations

摘要

The device (1) has an elastic washer plating a rolling bearing (8) against a circular piston (6) arranged between an inner ring (8a) of the bearing and a fixation clip, where the clip clips the bearing on a guide tube (7). The washer is arranged between the piston and bearing, and is immobilized in rotation with respect to the piston. Another metallic elastic washer has an anti-vibrating function, and is supported against the inner ring of the bearing and the piston in a manner to isolate the bearing from piston vibrations.
