Abstract
A damping valve, in particular for a vibration damper, including a cylinder filled with damping medium in which a piston rod with a piston is housed. The piston rod can move axially and the piston divides the cylinder into two working chambers. The damping valve can be adjusted by means of a magnet coil in connection with an armature and has an emergency operating setting. A stop is provided for the valve position for the emergency operating setting. The position of the stop relative to the armature can be used to define a passage cross section for the emergency operating setting.
