PROBLEM TO BE SOLVED: To suppress an increase in an energy loss of a cylinder rotation type compressor.SOLUTION: In the inside of a rotor 22 eccentrically rotating with respect to the central axis C1 of a cylinder 21, a rotor side suction passage 22b is formed for guiding a refrigerant (compression object fluid) that outflows from a shaft side suction passage 24b formed in a shaft 24, to a compression chamber V side. Further, in the outer peripheral surface of the rotor 22, a circumferential direction suction passage 22c is formed for guiding the refrigerant outflowing from the rotor side suction passage 22b from the outlet side of the rotor side suction passage 22b to the compression chamber V side that is in a suction stroke. With this, the refrigerant is made to speedily flow into a compression chamber V that is in a suction stroke to suppress a pressure drop in the compression chamber V.SELECTED DRAWING: Figure 3 |
