Abstract
Hydraulic adjustable vibration damper with a piston fastened to a piston rod and dividing a work cylinder into two work chambers filled with damping fluid, whereby at least partly to control the damping force, an electromagnetically activated damping valve comprising a coil, a magnetic armature, a valve body and a valve seat pressurizes a flow passage. The connection between the armature and the valve body is designed so that it can be adjusted axially, to set the length of the valve stroke after assembly.
