HYDRAULIC SHOCK-ABSORBER Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydraulic shock-absorber has housing, rod, piston, and at least two pairs of vortex chambers arranged eccentrically with respect to the piston axis. One of the chambers in each pair is a compression chamber and the other one is a cushioning chamber. The axes of the vortex chambers in each pair are parallel to each other. Vortex compression and cushioning chambers are alternative in periphery direction, interconnected in the certain order through radial and tangential passageways, and are in communication with the shock-absorber spaces through central openings. Members of each vortex chamber is optimized in sizes that are defined by relationships presented in the invention description. EFFECT: improved shock absorbing. 2 cl, 11 dwg
