PROBLEM TO BE SOLVED: To provide a compressor showing a superior energy saving characteristic without requiring any usage of electrical power for a dryer and a cooler or the like.SOLUTION: A compressor 100 comprises a compressor main body 120, a receiver tank 330, an oil separator 340, and an evaporator J for getting compressed air from the receiver tank 330 to dehumidify it. To the evaporator J is connected a discharging port 102a of the compressor 100. To the evaporator J is connected an ejector E, to the outlet of the ejector E is connected a condenser G, and further a liquid receiver Y is connected to the outlet of the ejector E. One of flow passages at the outlet side of the liquid receiver Y is connected to a pump P, an output side of the pump P is connected to a steam generator JH, and the steam generating part in the steam generating device JH is connected to a nozzle NZ inserted from the bottom side in the receiver tank 330 through a fine pipe into the ejector E through an upper outlet through a helical pipe RA. The other flow passage at the outlet of the liquid receiver Y is connected to the upper part of the evaporator J through the expansion valve B. |
