Abstract
Damping valve assembly includes a first damping valve, which, in a first operating range, opens as the flow velocity of the damping medium increases, where a second operating range with a progressive damping force characteristic is influenced by a throttle in conjunction with a control slide, which can be moved into a closed position. The control slide has a pressure-actuated surface, which, as a function of the flow velocity of the damping medium, acts in the closing direction on the control slide.
