Vibration damper with a hydraulic pressure stop

A vibration damper with a hydraulic-mechanical pressure stop includes a cylinder filled with damping medium; a piston rod movable in and out of the cylinder, a first piston fixed to the piston rod with freedom of axial movement, a second piston spaced from the first piston, a transfer spring in the second working space for moving the second piston toward the third working space in response to movement of the first piston toward the second working space; and a disk valve which allows damping medium to flow from the third working space through the second piston to the second working space as the second piston moves toward the third working space. The first piston divides the cylinder into a first and a second working space where the piston rod extends through the first working space. The second piston separates the second working space from a third working space.
