FIELD: mechanical engineering; shock protection equipment. ^ SUBSTANCE: proposed shock absorber contains reservoir, cylinder placed in reservoir, rod piston installed in cylinder, holes made in middle part of cylinder and overlapped in turn by piston, two valves designed to pass liquid from under-piston and over-piston spaces of cylinder into reservoir, throttling member made in form of insert with calibrated hole, two hydraulic channels and brake device. The latter is made in form of cylindrical capsule with two plungers dividing the space into three parts, namely, upper middle and lower ones, spring installed between plungers, and stop. First hydraulic channel connects over-piston space of cylinder with upper space of cylindrical capsule. Second hydraulic channel connects under-piston space of cylinder with lower space of cylindrical capsule. Stop is made in form of bushing being secured in middle part of cylindrical capsule. Plungers are arranged at different sides of stop. Ends of spring are secured on end faces of plungers. Reservoir is connected with middle space of cylindrical capsule by tube. Throttling member is installed in tube. ^ EFFECT: provision of optimum interrupted stepped compensating action. ^ 3 dwg |
