Abstract

A vibration damper is disclosed having a valve actuation device and a housing, in which housing the valve actuation device can be located. The valve actuation device has a controllable coil form, a coil core, and a movable armature for executing an actuation motion. At least a portion of the housing of the vibration damper can represent a magnetic return body for the magnetic flux generated by the coil form.
