Abstract
The cylinder is filled with damping medium. The vibration damper also includes a damping valve which is active as a function of pressure. The damping force of the damping valve can be modified by means of an actuator against a spring force on a shutoff valve body. An admission valve with its own damping action is connected hydraulically in series with the damping valve, so that the action of the admission valve is superimposed on the action of the adjustable damping valve.
