ABSTRACT:
A hydraulic shock absorber for a vehicle comprising a hydraulic cylinder with a piston which divides the cylinder into an upper compartment and a lower compartment, a damping chamber, and a return chamber. A control valve is provided in the path from the damping chamber to the upper compartment. A shock sensor is provided to detect the shock to which the vehicle is subject. When the shock exceeds a predetermined level, the shock sensor will give a signal to the control valve to close it, thus ensuring the shock to be absorbed by a spring in the damping chamber.
