Claim 1:
2. The refrigeration cycle apparatus of claim 1, wherein
the compressor includes
a compression mechanism unit having an orbiting scroll and a fixed scroll,
a frame configured to support the orbiting scroll from below, and
a hermetic vessel that houses the compression mechanism unit and the frame and stores refrigerating machine oil at a bottom portion of the hermetic vessel,

the fixed scroll has a first scroll lap,
the orbiting scroll has a second scroll lap that is combined with the first scroll lap to form a compression chamber together with the first scroll lap,
the compression mechanism unit is configured to suck refrigerant from a suction chamber into the compression chamber, the suction chamber being formed on outer peripheral sides of the first scroll lap and the second scroll lap, and
when refrigerant flows from the injection pipe into the hermetic vessel, refrigerant flowing through the injection pipe flows into the suction chamber.
