The present relates to a valve arrangement (1) for controlling a flow of damping medium in a shock absorber. The invention is based on the inventors' realization that the radial forces from the distributed pressurized damping fluid and axial forces generated by the flow velocity of the fluid acting on the slidable valve member (5) generates both radial friction forces and axial disturbing forces which both affect the axial position of the slidable valve member (5). Therefore, the inventors' have invented a valve arrangement (1) where the pressurized damping fluid acts around the whole circumference of the slidable valve member (5) and the impact of flow forces on the slidable valve member (5) is minimized, which vastly decrease the disturbing axial forces and thereby achieves a more dependable valve arrangement (1) with a reliable operation. |
