Abstract:
A vibration damper with hydraulic damping of a pressure stage stop may include a working piston guided in a damper tube along a longitudinal axis. The working piston may be disposed on a piston rod leading out of the damper tube. For damping the pressure stage stop, a tubular body may be disposed in the damper tube, within which an auxiliary piston can be accommodated such that the auxiliary piston is guided along the longitudinal axis. A spring element may pre-stress the auxiliary piston towards the working piston. Upon a drive-in movement of the piston rod into the damper tube, a stop piston that is movable with the working piston comes to lie against the auxiliary piston and together with the auxiliary piston plunges into the tubular body under a hydraulic damping effect and under compression of the spring element. Consequently, a damping agent in the tubular body may flow through the auxiliary and stop pistons. A flow cross-section geometry may be formed in the tubular body, through which the damping agent flows out of the tubular body parallel to a throughflow through the stop piston when the auxiliary piston and the stop piston drive into the tubular body together. The flow cross-section geometry may become smaller as the drive-in path increases.”

Claim (Index 11):
A vibration damper with hydraulic damping of a pressure stage stop, the vibration damper comprising:\n a damper tube; a working piston guided in the damper tube along a longitudinal axis, wherein the working piston is disposed on a piston rod leading out of the damper tube; a tubular body disposed in the damper tube for damping the pressure stage stop, the tubular body including a flow cross-section geometry; an auxiliary piston disposed in the tubular body such that the auxiliary piston is guided along the longitudinal axis, wherein the auxiliary piston is pre-stressed in the tubular body in a direction towards the working piston by a spring element; and a stop piston that is movable with the working piston, wherein upon a drive-in movement of the piston rod into the damper tube the stop piston comes to lie against the auxiliary piston and together with the auxiliary piston plunges into the tubular body under a hydraulic damping effect and under compression of the spring element, whereby a damping agent present in the tubular body is displaced and flows through the auxiliary piston and the stop piston, wherein the damping agent flows through the flow cross-section geometry out of the tubular body parallel to a throughflow through the stop piston when the auxiliary piston and the stop piston drive into the tubular body together, wherein the flow cross-section geometry is formed such that the flow cross-section geometry becomes smaller as a path of the drive-in movement increases.
