HYDRAULIC DAMPER WITH ELECTRIC GENERATOR Russian patent published in 2017 - IPC F16F5/00 B60G13/14 F16F15/03 F03G7/08 F16F9/16 

FIELD: machine building.

SUBSTANCE: invention relates to automotive industry. Damper comprises working cylinder (1) with working fluid and installed inside rod (2) with spring (3) and composite piston (4) with compression (5) and recoil (6) valves. Compensation chamber (7) is connected with working cylinder (1) via high pressure pipeline (8) and has inside additional piston (9) separating working fluid and inert gas, and dividing piston (10) with valve (11). Around compensation Chamber (7) lower part electric generator winding (12) is installed, concentrically to which annular permanent magnet (13) is arranged. In high pressure pipeline (8) there is sealing piston (14). Working fluid in cavities from sealing piston (14) to additional piston (9) is ferromagnetic fluid. Concentric to sealing (14) and additional (9) pistons annular permanent magnets (15) are arranged.

EFFECT: enabling damper elements oscillations energy recovery into electric energy.
