ABSTRACT:
An apparatus for damping spring-mounted wheel suspension systems is disclosed as having a cylinder filled with damping medium. The cylinder is divided by a piston on a piston rod into two work chambers. The two work chambers are connected to one another by damping valves and an additional fluid connection. The additional fluid connection is provided with a non-return valve between the two work chambers. The non-return valve has an actuator which can be switched as desired inside a valve device. The valve device has a damping force adjustment which acts in opposite directions for the two directions of flow. At least one non-return valve is dependent on the direction of flow and is provided with resistance. The non-return valve is moved into its operating position by the actuator.
