PLANT FOR DEGASSING LIQUID FOR HYDRAULIC SYSTEM Russian patent published in 1995 - IPC

FIELD: hydraulics. SUBSTANCE: portion of the liquid entering the inlet is fed from the preliminary filled degassing tank to the hydraulic tank by way of the ejector. Simultaneously, the liquid is fed from the pipe line through the throttle. The degassing tank is evacuated. The throttle controls rarefication. Air released in the degassing tank displaces the liquid from the degassing tank to the hydraulic tank resulting in increasing pressure in it. When the pressure in the hydraulic tank reaches a given value, the valve is opened and a portion of the liquid by-passes into the compensation vessel. The liquid, entering the compensation vessel, compresses the air which is kept in it by way of the valve of positive pressure of the breather. In so doing, a positive pressure is created in the compensation vessel. This positive pressure prevents against supplying of the air to hydraulic tank from the atmosphere. EFFECT: enhanced efficiency. 1 dwg
