PRESSURE MAINTENANCE APPARATUS FOR OIL TANK
본 발명에 따른 작동유 탱크의 압력유지장치는 작동유 탱크(1)의 내부 압력과 외부 압력의 차이에 따라 상기 작동유 탱크(1)의 공기를 외부로 배출하거나 외기를 상기 작동유 탱크(1)의 내부로 유입시키는 에어브리더(100); 및 상기 작동유 탱크(1)의 내부 압력이 하한 압력보다 낮으면 상기 작동유 탱크(1)의 내부 압력을 상승시키는 가압 유닛(200)을 포함한다.
PURPOSE: A pressure maintenance device for an oil tank is provided to prevent the reduction of suction performance or damage of a hydraulic pump caused by the internal pressure of an oil tank below the lower limit. CONSTITUTION: A pressure maintenance device for an oil tank comprises an oil tank(1) which is installed in construction equipment to store working oil, an air breather(100) which discharges the internal air of the oil tank to outside or draws in the exterior air into the oil tank according to the pressure difference between the interior and exterior of the oil tank, and a pressing unit(200) which raises the interior pressure of the oil tank when the interior pressure is lower than the preset pressure limit.
