| 摘要 |
he invention relates to self-acting hydraulic shock absorbers system composed of single-pipe shock absorbers (11,12,13,14) comprising hydraulic valves (7,8,9,10) composed of pistons destined for the function of the shock absorbers (15,16), regulators for the smooth and tough absorption of shocks (17, 18), pistons (19,20) for the actuation pressure of the system, the pressure regulator (21), pistons for the reciprocation of the pistons of the shock absorbers (22.23), the hydraulic brain (3) bearing the pressure regulator (4), the counterweight (6) placed on the brain axle (5) commanding the externally positioned hydraulic valves of the single-pipe shock absorbers, the hydraulic pressure pump (2), the oil box (1) and the pressure pipes arrangement (35,36,37,38,39,40,41,42,43,44,45,46,47,48,49) feeding oil to the circuit of the system. Instead of single-pipe shock absorbers (11,12,13,14), the system in question may comprise -for the lifting operation- double-pipe shock absorbers (24,25,26,27) and a hand-operated control (32) bearing the piston (33), and the pressure regulator (34). |
