Abstract
Hydraulic adjustable vibration damper with a damping piston, which divides the work cylinder into two chamber halves, whereby the two chamber halves are connected with one another by a bypass, in which an electromagnet controls the bypass. The bypass valve located in the bypass includes an axially-movable valve body which works together with a passage and which is controlled by the adjustment apparatus, and at least one spring-loaded valve which operates as a function of the pressure connected in series with the valve body.
