Damping valve device for a vibration damper

Abstract

A damping valve device for a hydraulic vibration damper for a vehicle comprises a drive region and a valve region, and a damper valve housing, with a tube part which encloses the drive region and the valve region, wherein the drive region has a coil which is configured in such a way that it generates a magnetic circuit within the damping valve device and interacts with an armature, attached axially movably within the coil, in order to move the armature in the axial direction, wherein the armature is arranged within a pole tube, and the pole tube forms an axial guide of the armature, wherein the valve region has a fluid inlet and a fluid outlet for admitting and discharging a hydraulic fluid into/out of the valve region, and a valve block with a plurality of flow passages for conducting the hydraulic fluid, wherein the valve region has a control slide which is attached such that it can be moved relative to the valve block in such a way that it can be moved between a closed position, in which the flow passages are closed by the control slide, and an open position, in which the flow passages are free, wherein the pole tube is configured in one part and/or in one piece and encloses the armature and the control slide, and wherein the magnetic circuit comprises the tube part and the pole tube.
