Abstract

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.
