Abstract
A vibration damper having a sensitive response behavior at very low amplitudes comprises a separating piston being disposed inside a bypass so as to move axially freely. The separating piston divides the bypass into two chambers mutually sealed from one another. Two valves are disposed in the bypass. The first valve acts in a compression stage as a pressure limiting valve and as a non return valve in an extension stage. The second valve acts as a pressure limiting valve in the extension stage and as a non return valve in the compression stage.
