Abstract
A vibration damper with variable damping force, including a cylinder, in which a piston with a piston rod is arranged in axially movable fashion, whereby an adjustable damping valve is activated in dependence on the deflection distance and the activation of the adjustable damping valve is carried out via a stabilizer. The vibration damper has further damping valves, whose damping effects are independent of activation by the stabilizer. The adjustable damping valve, during equilateral deflection and rebound travel of the piston rod on a vehicle axle or unilateral rebound travel, has a damping force setting that is smaller than the damping force of the further damping valves of the vibration damper.
