Abstract
A damping valve device for a vibration damper is disclosed, the damping valve device comprising a valve body of variable diameter, which is guided by a valve support and, starting from a passage position, adopts a restricting position as a function of a speed of flow of a damping medium within the restriction by a radial closing movement in the direction of a flow guiding surface. The closing movement of the valve body is controlled by at least one damping device.

A restriction for a vibration damper, comprising a valve body of a variable diameter, which is guided by a valve support, and, starting from a passage position, the valve body adopts a restricting position as a function of a speed of flow of a damping medium by a radial closing movement in a direction of a flow guiding surface, wherein the closing movement of the valve body is controlled by at least one damping device acting against the valve body as the valve body moves in the direction of the flow guiding surface, wherein the damping device is movable to an engaging position from a home position of the valve body.
A restriction for a vibration damper, comprising a valve body of a variable diameter, which is guided by a valve support, and, starting from a passage position, the valve body adopts a restricting position as a function of a speed of flow of a damping medium by a radial closing movement in a direction of a flow guiding surface, wherein the closing movement of the valve body is controlled by a plurality of damping devices acting against the valve body as the valve body moves in the direction of the flow guiding surface, wherein each of the damping devices are movable to an engaging position at different diameter sizes of the valve body.
