  • Adjustable damping valve device with a damping valve
    Patent number: 10208827
    Abstract: An adjustable damping valve device with a damping valve has an elastic element, applies an axial relative force between two elements which are constructed so as to be axially movable relative to the valve housing, or the elastic element applies a relative force between an element of the damping valve, which element is constructed so as to be axially movable relative to the valve housing, and the valve housing, or the elastic element applies a relative force between an element of the damping valve, which element is constructed so as to be axially movable relative to the valve housing, and an element which is constructed so as not to be displaceable relative to the valve housing, so that one of the axially movable elements releases a flow passage for the flow of damping medium through the damping valve at least in a neutral state of the damping valve device.

  • Damping valve comprising a pressure relief valve
    Patent number: 10100895
    Abstract: An adjustable damping valve (12) includes a pressure space (22c) for controlling the damping valve (12), which pressure space (22c) is arranged inside the damping valve (12) and is connected to a further space (20) via at least one choke orifice (30) for the flow of damping medium, and the pressure space (22c) is operatively connected to the further space (20) via a pressure relief valve (32).
