Fluid vibration damper for energy regeneration

摘要

The present invention is a vibration damper (1) that performs energy regeneration, and has one cylinder (3), and one displacer (5; 7) in one working chamber (9; 11) in the cylinder. Performs a limited driving action, whereby pressure fluid is supplied to the fluid motor (27), which drives the generator, in which the balance chamber (15) counteracts the change in volume of the pressure fluid. It relates to a vibration damper. According to the invention, the balance chamber (15) is additionally provided with a pressure reservoir (45), which is connected to the fluid motor (27) and connected in parallel. Proposed.
