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: A compressor uses a refrigerant containing R1123 (1,1,2-trifluoroethylene) as a working fluid, and uses a polyvinyl ether oil as a compressor lubricating oil. In addition, a fixed scroll (12) and a revolving scroll (13) each having a spiral lap rising from an end plate, and a compression chamber (15) which is formed by meshing the fixed scroll (12) and the revolving scroll (13), are provided. In addition, a discharge hole (18) which is provided at a center position of the end plate of the fixed scroll (12), and is open to a discharge chamber (31), a bypass hole (68) which is provided in the end plate of the fixed scroll (12), and communicates with the compression chamber (15) and the discharge chamber (31) at a timing different from a timing at which the compression chamber (15) communicates with the discharge hole (18), and a check valve which is provided in the bypass hole (68), and allows a flow from the compression chamber (15) side to the discharge chamber (31) side.
