ABSTRACT:
Vibration damper with a damping medium-filled cylinder, in which a piston rod is installed with freedom of axial movement, and a pressure container, which is connected to the vibration damper by an adapter piece. The adapter piece comprises a connecting part, which is connected to the pressure container, and an upper part, which is connected permanently to the vibration damper. A filling channel inside the adapter piece is open at both ends when the pressure container is full, and a filling channel on the vibration damper side, which is connected to the filling channel of the adapter piece, has a closing element.
