PNEUMOHYDRAULIC ACCUMULATOR

摘要

FIELD: accumulators of liquid energy; pressure fluctuation dampers. SUBSTANCE: device includes housing with piston divider for diving media between its chambers, additional piston mounted in correcting chamber which is brought in communication with pneumatic chamber of accumulator. Additional piston is stepped in its form it is mounted in chambers having different sections. After-piston chambers may be connected with main line and with return line. Maximum stage of additional piston is more than main piston. Housing of pneumohydraulic accumulator is provided with retainers for stopping the additional piston in required position. Line connecting the after-piston chambers of additional pistons with main line is provided with pressure converter. EFFECT: extended functional capabilities; wide range of adjustment of hydraulic system parameters.
