    Abstract: In an asymmetrical scroll compressor, at least one injection port through which an intermediate-pressure refrigerant is injected into a first compression chamber and a second compression chamber, at least one injection port penetrating an end plate of a fixed scroll at a position where the injection port is open to the first compression chamber or the second compression chamber during a compression stroke after a suction refrigerant is introduced and closed. Further, the amount of a refrigerant injected from an injection port into the first compression chamber is made more than the amount of a refrigerant injected from the injection port into the second compression chamber.

    Abstract: A compression chamber includes the compression chamber partitioning member, an intermediate pressure chamber guides an intermediate pressure working fluid before injection to the compression chamber, and the intermediate pressure chamber and the compression chamber face each other with a compression chamber partitioning member interposed between the intermediate pressure chamber and the compression chamber. Further, the intermediate pressure chamber includes an intermediate pressure chamber inlet through which an intermediate pressure working fluid flows, an injection port inlet of an injection port through which the intermediate pressure working fluid is injected into the compression chamber, and a liquid reservoir formed at a position below the intermediate pressure chamber inlet, and the liquid reservoir is formed by the compression chamber partitioning member.

    Abstract: In a scroll compressor according to the present invention, at least one injection port penetrating a second end plate of a fixed scroll at a position where the injection port is open to a first compression chamber or a second compression chamber in a compression stroke after the suction refrigerant is introduced and closed. Further, the discharge bypass port is disposed such that a volume ratio, which is a ratio of a suction volume to a discharge volume of the second compression chamber at which the refrigerant in the first compression chamber can be discharged, is smaller in the first compression chamber, which is one compression chamber having the large amount of the refrigerant injected from the injection port, than in the second compression chamber, which is the other compression chamber among the first compression chamber and the second compression chamber.

    Abstract: A compression element 3 includes a substantially spiral oil groove 23 which is provided in inner peripheral surfaces of bearings 14 and 15 of the shaft 6. One end of the oil groove 23 opens at a bearing base portion 24, and the other end of the oil groove 23 opens at a bearing end 25. According to this configuration, oil in a gap between the shaft 6 and inner peripheries of the bearings 14 and 15 forcibly discharges, into the hermetic container 1, gas bubbles generated in a sliding gap between the shaft 6 and the bearings 14 and 15 by action of a viscosity pump generated by the substantially spiral oil groove 23, and it is possible to provide a rotary compressor capable of preventing seizing and wearing caused by gas-involvement at a bearing sliding portion, and capable of securing reliability when refrigerant including R32 is used.
