Estimating the term…
A throttle point for a vibration damper, comprising a damper valve carrier with a circumferential annular groove, in which an annular valve body with a variable diameter is arranged. The annular valve body forms, with a guiding face for flowing damping medium, a throttle point, a throttle cross section of which decreases in the case of an increasing flow velocity of the damping medium within the throttle point. The circumferential annular groove forming a pressure chamber which is filled with damping medium. A radially outwardly directed actuating force acts on the valve body, wherein the pressure chamber is a constituent part of a hydraulic system which has a connector to at least one working space of the vibration damper and the hydraulic connection of which to the pressure chamber can be set.
