1. 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 flow guiding face for flowing damping medium, the throttle point, a throttle cross section of which decreases with an increase flow velocity of the damping medium within the throttle point, the circumferential annular groove forming a pressure chamber which is filled with damping medium, wherein a radially outwardly directed actuating force acts on the valve body, the pressure chamber being a constituent part of a hydraulic system of the damper valve device, wherein the hydraulic system has a connector to at least one working space of the vibration damper, wherein a hydraulic connection of the connector to the pressure chamber is adjustable, and wherein a connecting channel is positioned between two working spaces of the vibration damper, and wherein a bypass channel is connected hydraulically in parallel with the connecting channel, the connecting channel and the bypass channel being connected to the pressure chamber, and wherein an active cross-section of the bypass channel is adjustable.
