ABSTRACT:
A shock absorber assembly including a cylinder having a piston and piston rod mechanism movable relative thereto is formed with a hydraulic-mechanical damping system interposed in an annular space defined between the piston rod and the cylinder. The damping characteristics of the system are varied in accordance with the relative movement of the piston rod out of the cylinder by a damping mechanism which includes a spring, an annular member and a damping component operating to vary the cross-sectional area of the damping passage defined therethrough.
