PROBLEM TO BE SOLVED: To enable it to improve a valve structure capable of reducing pressure loss and vibration where a fluid passes, and its compression efficiency, besides preventing noise from occurring. SOLUTION: The leg part 53s of a discharge valve 53 is provided with a second flow-through hole 101 allowing a flow of refrigerant gas in a valve opening state in the discharge valve 53. Likewise, a third flow-through hole 102 is installed on an incline 54a of a discharge retainer 54 regulating the maximum opening of the discharge valve 53 so as to make it continue to the second flow-through hole 101 in a contacted state with the discharge valve 53. In addition, the tip part 51a of an inlet valve 51 is provided with a fourth flow-through hole 103 allowing the flow of the refrigerant gas in a valve opening state in the inlet valve 51. Then, a cut flow groove 104 is formed on a bottom face 52a of an inlet valve stopper 52 regulating the maximum opening of the inlet valve 51 so as to make it continue to the fourth flow-through hole 103 in a contacted state with the inlet valve 51.
