In the self-pumping type shock absorber wherein the working fluid is pumped up from a reservoir to an accumulator by a pump operated in accordance with the expansion and contraction stroke of the shock absorber cylinder-piston assembly so that the pressurized working fluid is supplied to the cylinder chamber space of the cylinder-piston assembly so as to increase the overall length of the cylinder-piston assembly such as to increase the vehicle height supported thereby, the passage for conducting the pumped up working fluid into the accumulator and the passage for conducting the stored high pressure working fluid from the accumulator into the cylinder chamber space are separated and a variably controllable throttle is provided in the latter passage, so that a variably controlled additional damping force is uniformly available throughout the expansion and contraction strokes of the shock absorber. |
