PROBLEM TO BE SOLVED: To increase an injection flow rate without changing the outer diameter of an injection check valve.SOLUTION: In a scroll compressor 100 where injection refrigerant is injected from an injection port 1f to a compressor 20, an injection check valve mechanism 35 is provided in the injection port 1f; the injection check valve mechanism 35 comprises an injection check valve 35a and a spring 35b arranged on the inflow hole side of the injection port 1f; and a central position in a direction orthogonal to the axis of the injection check valve 35a is installed so as to deviate from a central position in a direction orthogonal to the axis of the outflow hole of the injection port 1f. |
