ABSTRACT:
Self-pumping hydropneumatic shock absorbing leg with internal level regulation, in which the dampening force can be controlled and continuously adjusted during operation of a vehicle. For this purpose, the work piston of the shock absorber is provided with a check valve, whereby a passage runs from one work chamber to an adjustable dampening valve, and from this damping valve, a flow connection runs directly or indirectly via at least one additional check valve into the other work chamber and into a circulation passage which forms a connection to the high pressure chamber.
