FLUID-PRESSURE SHOCK-ABSORBER Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: fluid-pressure shock-absorber has housing, major rod and piston, cylinder coaxially mounted inside the housing, hollow rod with a rod mounted inside the cylinder, and additional rod with a piston arranged in its space. A baffle with openings is secured to one of the end faces of the cylinder without any spaced relation with respect to the housing. Valves are received in the openings of the baffle. The surfaces of the cylinder and hollow rod that face each other are provided with stops for permitting interaction with each other. The major rod and piston are received in the cylinder to form a hydraulic space and space connected with the atmosphere. The major piston is mounted for permitting interaction with the hollow and additional rods. EFFECT: improved shock-absorbing. 1 dwg
