ABSTRACT:
The invention relates to a shock absorber mounted between a suspended part and an unsuspended part of a vehicle and specifically a telescopic hydraulic shock absorber comprising a damping piston slidingly mounted in a cylinder. A compensation piston cooperates with the cylinder in order to maintain the damping piston and the cylinder in a given relative position during a variation in the load or centering of the vehicle. The compensation piston has at least one passage controlled by at least one valve sealing the passage to permit the normal operation of the shock absorber during a rapid deformation of the latter as a result of unevennesses of the road. One or more return springs maintain the damping piston at rest in a middle position relative to the cylinder facing a given zone of the latter.
Application to vehicle shock absorbers.
