A control unit 40 of the ICE 30 is configured to control the fluid pump 34 to regulate the pressure of the pressurised fluid towards a target pressure based on at least one operational parameter of the ICE 30. The target pressure corresponds to a target rotational speed of the centrifugal rotor.

Engine oil suppling apparatus

본 발명의 목적은 엔진열을 받아 기준치 이상으로 온도가 상승된 오일을 리턴시켜 냉각시킨후 공급되도록하여 엔진오일의 열화를 방지한 엔진오일 공급장치를 제공하는 데 있다. SUMMARY OF THE INVENTION An object of the present invention is to provide an engine oil supply device which prevents deterioration of engine oil by returning oil cooled after receiving engine heat and cooling it by returning oil whose temperature is raised above a reference value. 상기한 목적을 달성하기 위하여 본 발명은 The present invention to achieve the above object 오일을 저장하는 오일팬과, 오일팬내의 오일을 퍼올려 급송하는 오일펌프와, An oil pan for storing oil, an oil pump for pumping up oil in the oil pan, 급송되는 오일로부터 이물질을 여과하는 오일여과기와, 여과된 오일을 엔진의 각 운동부위에 공급하는 메인오일갤러리로 포함하는 엔진오일 공급장치에 있어서, In the engine oil supply device comprising an oil filter for filtering foreign matters from the oil to be fed, and the main oil gallery for supplying the filtered oil to each moving part of the engine, 상기 오일여과기를 통과한 엔진오일의 온도를 검출하는 오일온도센서와; An oil temperature sensor detecting a temperature of the engine oil passing through the oil filter; 상기 오일여과기와 메인오일갤러리를 연결하는 오일라인으로부터 오일펌프 입구라인으로 분기접속되는 오일리턴라인과; An oil return line branched from an oil line connecting the oil filter and the main oil gallery to an oil pump inlet line; 상기 오일리턴라인과 오일라인의 접속지점에 설치되는 2방향 체크밸브와; A two-way check valve installed at a connection point between the oil return line and the oil line; 상기 오일리턴라인의 도중에 설치되는 오일냉각기와; An oil cooler installed in the middle of the oil return line; 상기 오일온도 센서로부터 검출된 오일온도가 기준치 이상일 때 상기 2방향 체크밸브가 오일리턴라인을 개방하도록 제어하는 전자제어장치와;를 포함하여 구성되는 것을 특징으로 한다. And an electronic controller for controlling the two-way check valve to open the oil return line when the oil temperature detected by the oil temperature sensor is equal to or greater than a reference value.
