Damping valve device for a vibration damper

A damping valve device for a hydraulic vibration damper for a vehicle, comprising:

• a drive region and a valve region,
• a damping valve housing having a tube part which encloses the drive region and the valve region,
• wherein the drive region has a coil which is designed in such a manner that it generates a magnetic circuit within the damping valve device and interacts with an armature that is attached so as to be axially movable within the coil, in order to move the armature in the axial direction,
• wherein the armature is disposed within a pole tube, and the pole tube forms a guide of the armature,
• wherein the valve region has a fluid inlet and a fluid outlet for letting a hydraulic fluid into and out of the valve region, and a valve block having a plurality of flow passages for conducting the hydraulic fluid,
• wherein the valve region has a control slide which is attached so as to be movable relative to the valve block in such a manner that it is movable between a closed position in which the flow passages are closed by the control slide and an opened position in which the flow passages are free,
• wherein an annular space filled with hydraulic fluid is delimited by the control slide, the pole tube and the valve block, and wherein the annular space has at least two different external diameters, wherein the annular space has a first annular space region and a second annular space region, and wherein the first annular space region is delimited by the control slide and the second annular space region comprises flow ducts which are formed between the valve block and the pole tube.
