Patent ID: 8151953

Claim:
A suspension and damping device for load bearing and sprung wheel support and for damping suspension movements in a motor vehicle, comprising at least one spring cylinder assembly having a piston which is guided in a spring cylinder so as to be movable relative to the spring cylinder and which acts counter to an elastically compressible spring medium of a spring medium circuit in order to generate a load bearing supporting spring force, a separate circuit of a hydraulic damping medium for damping defining a damping medium circuit and which is independent of the spring medium, wherein the piston separates the spring medium circuit from the damping medium circuit including separating a first working chamber and a second working chamber from one another within the cylinder, the first working chamber communicating with a first volume of the spring medium and the second working chamber communicating via a hydraulic line with a second volume of the damping medium in a separate hydraulic container remote from and entirely outside the cylinder, the separate hydraulic container having an inlet region with a damping valve arrangement, the piston having, on one side thereof, a piston rod connected to the piston extending outwardly out of the spring cylinder such that a seal is provided between the piston rod and the spring cylinder, with the result that the second working chamber is configured as an annular chamber which encloses the piston rod, the first working chamber being disposed adjacent a side of the piston opposite the piston rod, and filled with the elastically compressible spring medium.
