HYDRAULIC SPOOL VALVE DISTRIBUTING DEVICE |
摘要 |
FIELD: working cylinders at non-uniform speed of motion of piston. SUBSTANCE: volume flow of working fluid acting on piston is aligned with respective speed of piston; required direction of motion of piston is set by means of servo-controlled distributor. Reversible distributor is hydraulically regulated by control distributor which is controlled by command pulses for working cylinder. Built in between control passages from control distributor to reversible distributor is hydraulically-operated servo-acting control distributor through which one of two volume flows of working fluid passes; definite speed of motion of piston corresponds to each position of distributor. EFFECT: simplified construction. 5 cl, 1 dwg
