PROBLEM TO BE SOLVED: To suppress vibration of a valve body of a check valve in a compressor having the check valve in a discharge passage.SOLUTION: A first refrigerant flow channel 57a and second refrigerant flow channel 58 having a different flow channel cross section are formed on the downstream side of a discharge valve in the flow direction of refrigerant gas and on the upstream side of a valve body 65 of a check valve 52. The first refrigerant flow path 57a extends straight in the axial direction of a branch flow channel forming member 57. The second refrigerant flow channel 58 extends helically from the discharge valve side toward the valve body 65 side. The flow channel cross section of the second refrigerant flow channel 58 is smaller than that of the first refrigerant flow channel 57a. |
