PROBLEM TO BE SOLVED: To provide a compressor capable of improving compression efficiency, by enhancing heat exchange efficiency of a spray drop. SOLUTION: This gas machine has an impeller 3, a casing body 10 storing the impeller 3 and forming a flow passage R<SB>1</SB>for sending gas toward the impeller 3, and an ultrasonic vibration type spray device 30 arranged on the upstream side of the impeller 3 of the flow passage R<SB>1</SB>and spraying the spray drop F in air A<SB>O</SB>sent at a predetermined flow speed. The spray drop F is set to 1 m/s or more in a flow speed flowing in the impeller 3. COPYRIGHT: (C)2009,JPO&INPIT
