A vibration damper with a piston, a piston rod fastened to the piston, a working chamber divided by the piston into a first working chamber and second working chamber, and a generator drivable by movement of the piston rod. The damping force of the vibration damper can be influenced by energization of the generator. An energizable component part is provided that short-circuits the windings of the generator when unenergized and cancels the short circuit when energized.

Vibration damper and motor vehicle

Energy-recuperating vibration damper having a cylinder in which a displacer executes a limited operating movement in a working chamber so that a pressurized fluid is supplied to a fluid motor which drives a generator. A compensation chamber compensates for a change in volume of the pressurized fluid. A pressure accumulator is provided in addition to the compensation chamber, which pressure accumulator communicates with and is parallel-connected to the fluid motor.
