Zusammenfassung:Vibration damper having an adjustable damping valve device comprising an actuator having a magnetic coil that applies a magnetic actuation force to an axially movable valve armature within a sleeve-like fixed return member that includes a conductive portion and an insulating portion. The return member cooperates with a pole disk that conducts a magnetic flux of the magnetic coil and on which an axial transfer of the magnetic flux for the actuating movement of the valve armature takes place. The insulating portion of the return member is adjoined in the direction of the pole disk by a second conductive portion and the valve armature axially overlaps the second conductive portion depending on the stroke.
