ABSTRACT:
A multistage compressor includes a lower pressure side compression part, a higher pressure side compression part, an intermediate conduit placing the lower and higher side compression parts in communication, and a cooler disposed midway of the intermediate conduit for allowing gas to flow from the lower pressure side compression part to the higher pressure side compression part and for cooling the flowing gas. The cooler includes a drain outlet port. The compressor further includes an electromagnetic valve disposed at the drain outlet port and a controller for controlling the valve. The valve is opened when the compressor is started or re-started after a pause, is kept open during a predetermined period of time, and is then closed.
