Vibration damper

A vibration-damper with adjustable damping force, comprising:

• an inner cylinder with at least one working chamber including a flow connection to a damper-valve device, wherein the damper-valve device is arranged outside of an outer cylinder of the vibration damper, wherein the flow connection is defined by a component that is separate from the inner cylinder, wherein the component is defined by a pressure-stage adapter which defines a part of the working chamber and which exhibits a coupling to the damper-valve device, and wherein a base piece is arranged at the end of the inner cylinder such that the base piece closes off the working chamber at the end of the inner cylinder, wherein the pressure-stage adapter and the base piece are combined to form a pressure-stage adapter device;
• wherein the pressure-stage adapter device is arranged inside and is surrounded and enclosed by the outer cylinder of the vibration damper at the end of the inner cylinder, such that the base piece is supported at an end of the outer cylinder remote from the piston rod.
