PROBLEM TO BE SOLVED: To provide a compressor that reduces pulsation while suppressing a pressure drop on the discharge side.SOLUTION: A flow divider 45 that divides a discharge passage 35 into a first branch flow channel 46 and a second branch flow channel 47 is disposed in the discharge passage 35 located in the downstream of a check valve 40 of a discharge chamber 23. The flow channel cross section S1 of the first branch flow channel 46 is set larger than the flow channel cross section S2 of the second branch flow channel 47. When the check valve 40 opens, a discharge refrigerant of the discharge chamber 23 is branched to the first branch flow channel 46 and the second branch flow channel 47. In the second branch flow channel 47, the flow channel cross section is smaller than the first branch flow channel 46, so that the flow of the refrigerant becomes slow due to channel resistance. Thus, speed difference occurs between the refrigerant flow in the first branch flow channel 46 and that in the second branch flow channel 47. Then, the discharge of the discharge refrigerant is leveled, and the pulsation is reduced. |
