ABSTRACT:
A hydraulic, adjustable vibration damper with a piston fastened to a piston rod, which piston divides a working cylinder into two working chambers filled with damping fluid, whereby at least partly to control the damping force there is a pilot-controlled, electromagnetically actuated damping valve. In this valve, a valve body and a pilot control element each apply pressure to a valve seat, and at least the valve body is mounted in a guide so that it can be displaced axially. The valve body consists of at least two parts, whereby one part is held in the axial guide and is connected to the second part so that the second part is located running in an additional axial guide, so that it can be displaced radially with respect to the first part. Whereby the valve seat of the valve body may be disposed adjacent either the first part of the valve body or the second part of the valve body.
