Oleopneumatic shock absorbing device including a hydraulic fluid-filled cylinder (1) combined with a movable assembly moved by outside forces for circulating the hydraulic fluid. The movable assembly consists of a hollow mobile piston (3) on the end of a push rod (2) with an internal longitudinal space (13) forming a reservoir for the hydraulic fluid. When the piston (3) and the push rod (2) are moved, the fluid flows through a variable flow-rate transfer channel (11) providing variable, e.g. gradual shock absorption throughout both the outward stroke and the return stroke. |
