Abstract

토출온도의 상승을 억제한다.The rise of the discharge temperature is suppressed.

프론트하우징(2)에 형성된 크랭크실(Crank case) (5)에는 외부냉각회로와 접속된 흡입구멍(40)이 열려 있으며 리어하우징(3)내의 흡입실(30)은 실린더블럭(1)을 경유하여 설치된 흡입통로를 통해서 크랭크실(5)와 연통됨과 동시에 흡입통로에는 그 통로단면적을 조정하여 흡입실압력을 변화시키는 조정밸브(45)가 내장되고, 조절밸브(45)는 흡입통로내의 양성압력을 거의 일정하게 억제하는 용량제어밸브(50)에 의해서 작동되도록 구성한 것으로서, 흡입실압력의 이상저하와 함께 토출온도의 상승이 억제된다.The crank case 5 formed in the front housing 2 has a suction hole 40 connected to an external cooling circuit, and the suction chamber 30 in the rear housing 3 passes through the cylinder block 1. The intake passage communicates with the crank chamber 5 through the suction passage, and at the same time, the suction passage has a control valve 45 for changing the suction chamber pressure by adjusting the passage section area, and the control valve 45 has a positive pressure in the suction passage. It is configured to be operated by the capacity control valve 50 which suppresses substantially constant, and the rise of the discharge temperature is suppressed with the abnormal decrease of the suction chamber pressure.
