Abstract
A valve for a vibration damper having a valve housing and a valve slide movable in the valve housing for at least partially closing at least one flow path of a fluid flowing through the valve. The valve has an input side and an output side. The pressure impingement surfaces of the valve slide for an opening pressure and for a closing pressure are substantially equal, and the valve slide has a constriction via which a pressure difference between opening pressure and closing pressure can be generated. At least one channel connects the interior space of the valve slide to the exterior space of the valve slide.
