TWO-SIDED SHOCK-ABSORBER Russian patent published in 2002 - IPC

FIELD: shock-absorbers with rod passing through two spaces of the cylinder. SUBSTANCE: housing (1) is filled up with fluid and has internal baffles (7) provide with axial and baffle (8) openings. Chamber (6) with compressed gas is rigidly fixed to baffles (7) and between them. Chamber (6) is provided with flexible diaphragm (16) which forms space (Б) in the axial direction. Tracking rod (5) is placed from both ends of the shock-absorber and is free to move inside the internal space (Г) of the main rod (2). Additional rod (3) is rigidly connected to main rod (2) and contains in the axial channel valve (4) and side openings (13). Rod (3) passes through axial opening of baffle (7). Space (Г) is connected to spaces (А, В) through side openings (13) and to space (Б) through valve (14). Spaces (A, B) are interconnected through passage of baffle opening (8). EFFECT: enhanced reliability of sealing the gas due to non- separable contact between rods and supporting surfaces. 4 cl, dwg
