Vibration damper having end stop

The invention relates to a vibration damper having an end stop operated by a damping medium, comprising a cylinder in which a piston is guided so as to be axially movable, wherein the piston rod controls a throttle ring which delimits a compression chamber from a defined stroke position of the piston rod on a cylinder side wall having a reduced diameter, wherein the cylinder has at least one working chamber filled with the damping medium and is connected to the compression chamber by means of at least one throttle opening, wherein the throttle ring has at least one pressure equalising channel, by means of which an outer surface of the throttle ring facing in the direction of the cylinder side wall is connected to the compression chamber based on the cross-section of the throttle ring and the drain of the pressure equalising channel to the working chamber can be closed as a function of the stroke. 具有通过减振介质运行的端部止挡的减振器，其包括缸，活塞杆可沿轴向运动地在缸中引导，其中，活塞杆操控节流环，该节流环从活塞杆的限定的行程位置起在直径减小的缸侧壁上限制出压缩腔室，其中，缸具有至少个填充有减振介质的工作腔室，该工作腔
