Abstract

To enable the prevention of smearing an equipment and its periphery with lubricating oil, the alleviation of a burden in maintenance of the equipment by reducing a decrement of the lubricating oil, and the lowering of running cost, an oil-cooled compressor has a suction control valve 5 in a suction passage 3 and an air discharge valve 9 in a discharge passage 6 in a compressor body 1. An oil discharge passage 16 is formed for leading outside the lubricating oil supplied to bearing and shaft seal sections of the compressor body 1, an oil return passage 17 communicating with the inlet side of the suction control valve 5, an oil reservoir section 18 located between the oil discharge passage 16 and the oil return passage 17, and an air discharge passage 19 arranged with one end connected to the outlet port of the air discharge valve 9 and its another end reaching the oil reservoir section 18. The lubricating oil is sent out towards the inlet side of the suction control valve 5 through the oil return passage 17 without reverse flow of the oil from the oil reservoir section 18 into the oil discharge passage 16.
