| 摘要 |
The invention concerns a damper, in particular for motor vehicle, comprising a cylinder containing a hydraulic fluid, a main piston (1) actuated by a rod (3) defining in the cylinder a first chamber (2a) and a second chamber (2), said second chamber containing the rod, a hydraulic fluid reservoir (6) and a valve (10) placed in the hydraulic fluid flow between the first chamber and the second chamber, said valve comprising a mobile check valve (28) co-operating with a seat (30) and means designed to press the check valve on its seat. The invention is characterized in that it further comprises filtering means mounted (16) in parallel with the valve (10), adapted to generate a filtering control pressure acting on the check valve, the control pressure depending on the pressure differential at the inlet and the outlet of the valve. |
