Hydraulic shock-absorber with guided valves

摘要

The shock-absorber comprises two or more valves 25 associated with two or more of the openings 24 passing through its piston 20 and one valve for making its main chamber communicate with a compensation chamber. Each of the valves 25 comprises a guide part 30 extending the head 26 and interacting with a housing 28 in which there is housed the return spring 27 for the valve. Any risk of vibration and noise upon opening of the valves is thus avoided. <IMAGE>
