Patent ID: 8887882

Claim:
A vibration damper with integrated level control, comprising: a hollow piston rod with a piston having at least two damping valves a fixed separating wall; a cylinder in which the hollow piston rod with the piston is guided so as to be axially movable, the piston divides the cylinder into a first work space on the piston rod side and a second work space remote of the piston rod bounded by the piston and the separating wall; a piston rod guide arranged in the cylinder so as to be movable axially and configured to limit the first work space on the piston rod side; a pump space connected to the second work space remote of the piston rod by at least one connection opening in the separating wall, the connection opening having a valve that opens directly into the second work space remote of the piston rod; a hollow rod supported by the separating wall on which the piston slides and that controls the pump operation of the vibration damper; a compensation space defined at least by an outer face of the axially movable piston rod guide that receives a damping volume displaced by the piston rod due to a dynamic load; and a vehicle suspension spring supported at the outer face of the axially movable piston rod guide.
