Abstract
In previously known shock absorbers, a throttle cross section can be controlled with the aid of a control slide. Because flow forces can never be avoided entirely, the magnetic force must be controlled as a function of the flowing pressure fluid flow. In the cylinder proposed here, having a control slide, an additional force acting upon the control slide results, which is directed counter to these flow forces and can at least partially compensate for them. The proposed cylinder is intended in particular for use as a shock absorber for vehicles.
