HIGHLY EFFICIENT SHOCK ABSORBER Russian patent published in 2004 - IPC

FIELD: shock absorber fluid cooling units. SUBSTANCE: shock absorber 1 includes double-acting piston 23 hermetically mounted for sliding in tube 36. Piston 23 at forced circulation of fluid acts on fluid in working chambers (A,B) and forces it through nozzle unit 38 for shock absorbing of impact converting oscillatory energy into heat. Then, fluid thus heated is directed to cooler built in shock absorber 1. Said cooler is made in form of at least two chambers (C,E) between housing 32 of shock absorber and tube 36. At least two chambers (C,E) interact through at least one throttling unit with suction passage for working chambers (A,B). EFFECT: enhanced reliability and efficiency; enhanced compactness. 7 cl, 3 dwg
