Scroll compressor having injection ports provided in outer circumferential surface between opening ends of communication paths and inlet ports for injecting liquid refrigerant in direction toward the inlet ports

A scroll compressor comprising:

• a sealed container;
• a motor element housed in the sealed container;
• a scroll compression element housed in the sealed container and configured to be driven by a rotating shaft portion of the motor element;
• and
• a frame placed between the motor element and the scroll compression element in the sealed container and configured to support the scroll compression element,
• the scroll compression element including
• a fixed scroll fixed to the frame and including a first scroll body and
• an orbiting scroll including a second scroll body configured to be engaged with the first scroll body to form a compression chamber between the first scroll body and the second scroll body, the orbiting scroll being configured to orbit opposed to the fixed scroll,
• a first space into which gas refrigerant sucked from outside flows being provided in the sealed container on a motor element side of the frame,
• a second space communicated with the first space through a communicating path being provided on an outer circumferential side of the first scroll body and the second scroll body,
• a scroll end portion of the first scroll body and a scroll end portion of the second scroll body being each configured to form an inlet port configured to suck the gas refrigerant into the compression chamber in a counter scroll involute direction from the second space,
• an open end of the communicating path on a side of the second space being located at an angle larger than 0 degrees and less than or equal to 180 degrees, around a central axis of the rotating shaft portion, from the inlet port in a scroll involute direction of the first scroll body and the second scroll body,
• an injection port being provided in a part of an outer circumference of the second space between the open end of the communicating path and the inlet port in a circumferential direction, the injection port being configured to eject liquid refrigerant in a direction toward the inlet port.
