  • Damping valve
    Patent number: 10436276
    Abstract: A damping valve includes a valve body with a stepped opening for receiving a preloading spring which acts on a tension rod at which is arranged a valve disk which at least partially closes a flow-out orifice of a flow channel which connects two opposite valve body sides to one another, and, in addition to the preloading spring force, a damping force which counteracts a swiveling movement of the valve disk acts on the tension rod. The additional damping force is formed by a displacer on the tension rod side. The display together with a portion of the stepped opening, forms a restrictor chamber.
