PLUNGER-PISTON DUAL-ACTION HYDRAULIC BOOSTER

摘要

FIELD: machine building.SUBSTANCE: hydraulic booster is designed to feed working fluid at high pressure at processing plants and working tool drives. Proposed booster comprises housing, differential slide valve to control high-pressure pump drive piston, booster plungers secured at piston both ends slide valve control distributors. Note here that booster plungers making the pump parts can force working fluid in rocking assy. Besides, they double as a distributor slide valve for automatic control of differential slide valve. Said plungers feature equal diameter while pressure channels with common outlet to consuming equipment feature common damping chamber.EFFECT: continuous feed of working fluid.3 dwg
