CYLINDER-ROTATION-TYPE COMPRESSOR

WIPO Patent Application WO/2016/189801

A1

According to the present invention, a first groove section (222a) in which a first vane (23a) partitioning a first compression chamber (Va) is fitted in a slidable manner, and a first rotor side intake channel (224a) which guides, to the first compression chamber (Va), a refrigerant flowed out from a shaft side intake channel (24a) formed in a shaft (24) are formed in a first rotor (22a) which rotates about an eccentric shaft (C2) eccentric to a center shaft (C1) of a cylinder (21). At that time, the first groove section (222a) is formed into a shape that extends to the rear side in the rotation direction, from the inner circumferential side toward the outer circumferential side, and the first rotor side intake channel (224a) is formed into a shape that extends so as to be inclined toward the front side in the rotation direction, from the inner circumferential side toward the outer circumferential side, such that a fluid outlet opening of the first rotor side intake channel (224a) is formed immediately rearward of the first groove section (222a) in the rotation direction. Thus, the refrigerant is quickly flowed into the first compression chamber (Va), which serves as an intake passage, thereby suppressing pressure reduction in the first compression chamber (Va).
