ABSTRACT:
Herein disclosed is a hydro-pneumatic self-levelling suspension unit for an automotive vehicle, serving not only as a shock-absorber responsive to jounces and rebounds of a vehicle body and a self-levelling mechanism capable of automatically adjusting the height of the vehicle body responsive to change in the load applied to the vehicle body but as a level selector mechanism which is manually operated to stepwise vary the height of the vehicle body. The level selector mechanism comprises means stepwise extensible in an axial direction of the suspension unit between a fully contracted position and a fully extended position and biased toward the fully contracted position. The extensible means is stepwise extended to one or more lengths between the fully contracted and extended positions by selective application of fluid pressure thereon.
