PROBLEM TO BE SOLVED: To provide a helical type compressor which contains an electric motor radially inside a roller and further increases refrigerant discharge capacity while suppressing enlargement of the body size.SOLUTION: In the helical type compressor 1, a case 10 includes a cylinder 11 and in the cylinder 11, the roller 50 makes an orbital motion with rotation of a rotor 30. At this time, a space between the inner peripheral face of the cylinder 11 and the outer peripheral face of a cylinder body 51 of the roller 50 is composed as a first compression chamber 65. The space between the inner peripheral face of the cylinder body 51 of the roller 50 and the inner peripheral face of the rotor 30 is composed as a second compression chamber 75. Refrigerant is compressed in the first compression chamber 65 and the second compression chamber 75, respectively. |
