Shock absorber comprising a piston inside which a sleeve is present which can be operated separately from the piston. This sleeve is provided with through-flow conduits which can cooperate with apertures, which are fitted at a vertical distance, of a part of the piston in order to provide an auxiliary flow when the piston is displaced in the cylinder. Such auxiliary flow enters into a chamber which is delimited by one or more spring plates which act on a sleeve which loads the main valve against opening when it is pressed down by the spring plate. By filling the chamber with fluid, the load applied on the sleeve by the spring plate is reduced and the load on the main valve decreases, as a result of which the latter opens more readily.

Damper which is, in particular, stiff during the inward stroke thereof and can be used, for example, as a railway damper. The piston which divides the cylinder into two chambers is provided with non-return valves which operate in both directions and are configured as characteristic. A sleeve extends from the bottom of the cylinder which is displaceable in the interior of the piston/piston rod and one end of which is connected to a reservoir and the other end of which may be connected to one of the chambers. In addition, a bottom valve is present in the cylinder. The combination of sleeve/bottom valve is fitted in such a manner that when the piston moves inwards in the cylinder, the liquid volume which has to be displaced is moved by additional rod volume which enters the cylinder via the sleeve in the reservoir. During the outward movement, the liquid is replenished from the reservoir via the bottom valve.
