Abstract
A hydraulic, adjustable vibration damper has an electromagnetically activated damping valve to at least partly control the damping force. In the electromagnet of the damping valve, the base of the armature guide and the end surface of the armature adjacent to the base are configured so that there is at least one recess in one of the parts, into which at least one recess, at least one correspondingly configured extension on the other part projects. With this configuration, the electromagnet is able to attain high forces, largely independent of the distance, over a short work stroke of the armature of the electromagnet.
