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: 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 scroll compressor according to the present disclosure includes a partition wall that divides a sealed vessel into a high-pressure space and a low-pressure space, a non-orbiting scroll provided in the low-pressure space, an orbiting scroll that forms a compression chamber between the orbiting scroll and the non-orbiting scroll, and a rotational shaft. The scroll compressor further includes a main bearing that supports the orbiting scroll, an elastic body that biases one of the non-orbiting scroll and the orbiting scroll so as to separate the non-orbiting scroll and the orbiting scroll from each other, and a plurality of columnar members that are fixed at one ends of the columnar members and are movable at the other ends of the columnar members, and are disposed in a circumferential direction. The non-orbiting scroll or the orbiting scroll that is biased by the elastic body is movable between the partition wall and the main bearing in an axial direction of the rotational shaft. The elastic body is disposed between the plurality of columnar members in the circumferential direction.
