Abstract
A second space communicated with a first space through communicating paths is provided on an outer circumferential side of first and second scroll bodies. Scroll end portions of the first and second scroll bodies form an inlet port configured to suck gas refrigerant into a compression chamber from the second space. Open ends of the communicating paths on a side of the second space are located at an angle larger than 0° and less than or equal to 180°, around a central axis of a rotating shaft portion, from the inlet ports in a scroll involute direction of the first scroll body and the second scroll body, respectively. Injection ports in a part of an outer circumference of the second space between the open ends and the inlet ports in a circumferential direction are configured to eject liquid refrigerant in a direction toward the inlet ports, respectively.
