Claims

[Scope of utility model registration request]

In an oil-cooled positive displacement compressor that separates gas discharged from a compressor body 1 into oil and gas in an oil tank 2 and returns the separated oil to the low pressure side of the compressor body 1, the oil tank 2 The oil refining tank 6 is connected to the oil refining tank 6 through a second pipe b for transferring part of the oil therein, and the first pipe is communicating the refined oil in the oil refining tank 6 to the low pressure side of the compressor main body 1. a, a fourth pipe line d that makes the internal pressures of the oil refining tank 6 and the oil tank 2 the same;
an exhaust means attached to the upper part of the oil refining tank 6 via a third pipe line C; a first on-off valve 8 for opening and closing the pipe line a; and a first opening/closing valve 8 for opening and closing the pipe line B, which is opened after the valve 8 is closed in the pipe line B. a second on-off valve 9, a third on-off valve 10 in the conduit C that opens after the valve 9 closes, and a third on-off valve 10 in the conduit C that opens after the valve 10 closes and then closes the A fourth valve that enables the valve 8 to be in an open state.
An oil-cooled positive displacement compressor characterized by being equipped with a lubricating oil refining device comprising an on-off valve 11.
