  • Patent number: 8978844
    Abstract: An adjustable damping valve arrangement for a vibration damper comprises an actuator which exerts an actuating force on an auxiliary valve body of an auxiliary valve. The auxiliary valve influences a closing force on a main stage valve. A pressure depending on the pressure level in a working space of the vibration damper acts on at least one pressure-impinged closing surface of the main stage valve via a flow connection. The flow connection is carried out so as to be functionally parallel to an incident flow of the main stage valve, and a flow-in opening of the flow connection is oriented at an angle of at least 60° to the flow direction into the main stage valve so that only a static pressure acts on the closing surface of the main stage valve.
