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

FIELD: mechanical engineering.

SUBSTANCE: hydraulic shock absorber comprises a working cylinder 1 with a working fluid and mounted within an integral stem 3 and piston 5 with a compression valve 6 and return valve 7. Compensation chamber 11 is connected to the working cylinder 1 and has an additional piston 12 inside, which separates the working fluid and the inert gas, and a separating piston 14 with the valve 15. The compensation chamber 11 is formed in the cavity of the rod 3. Around the middle part of the compensation chamber 11 there is coil 16 of the linear electric generator, which is concentrically positioned annular permanent magnet 17. The working fluid in the compensation chamber 11 is a ferromagnetic liquid.

EFFECT: energy recovery of the shock absorber elements vibrations into the electrical power.
