Abstract

PURPOSE:To increase the performance of a compressor by continuously forming a suction member and a discharge member having respective special angles with respect to the axial direction of a piston in a spiral groove arranged on the outer circumference of the piston and allowing a blade to enter therein or go out therefrom. CONSTITUTION:A compressor 20 is constructed by including an electrically driven element 22 and a compression element 23 in an enclosed case 21. The electrically driven element 22 is composed of a startor 24, fixed on the inwall surface of the enclosed case 21, and a rotor 25 provided inside of the startor 24. On the other hand, the compression element 23 is constructed by arranging a piston 27 eccentrically inside of a cylinder 26 fixed on the rotor 25. A spiral groove 40 for winding a blade 28 the eon is formed on the outer circumference of the piston. At this time, the groove 40 is formed by continuing a suction member, having an angle of 45 degrees or less with respect to the axial direction of the piston 27, and a discharge member having an angle of not less than 45 degrees nor more than 90 degrees.
