ABSTRACT:
An apparatus for damping movement courses of two bodies, in particular in a vehicle wheel/vehicle suspension system, having a piston sliding in a cylinder and dividing it into two work chambers, the two work chambers arranged to communicate with one another via respective oppositely acting check valves and via a variably asymmetrical damper valve adjustable in such a manner that upon a valve member movement the opening cross section for one flow direction decreases to the extent that it increases for the other flow direction, such that whenever in comparison with an active damper system energy would have to be supplied from outside, the damper force is substantially reduced to the value of zero.
