Abstract

The present disclosure relates to a vibration damper for a vehicle, comprising a damper tube filled with hydraulic fluid, a working piston, which is connected to a piston rod and is arranged movably back and forth within the damper tube. An interior of the damper tube is divided by the working piston into a first working chamber and a second working chamber, a closure package, which closes off the damper tube fluid-tightly on the piston rod side, an adapter, which is fitted inside the damper tube and is intended for attaching a damping valve device, and a compression stop assembly with an auxiliary piston, which is arranged axially movably within the damper tube. The auxiliary piston is arranged between the adapter and the end of the damper tube away from the piston rod.
