Claims

[Claims for Utility Model Registration] (1) A rotary piston that performs eccentric rotation is housed in a cylinder chamber whose both open ends are closed by a frame and a cylinder head, and the movement of the rotary piston causes the gas in the cylinder chamber to and a first discharge hole provided on the wall of the cylinder chamber and communicating between the inside and outside of the cylinder chamber, and a first discharge hole provided on the outside of the wall of the cylinder chamber and discharged to the outside of the cylinder chamber. a first reed valve in the shape of a curved plate that presses and closes one discharge hole; a second discharge hole provided in the frame or cylinder head and communicating between the inside and outside of the cylinder chamber; and a second discharge hole provided on the outside of the frame or cylinder head. A rotary compressor, comprising: a flat second reed valve that presses and closes the second discharge hole; and the first and second reed valves have different elastic forces. discharge valve device. (2) A discharge valve device for a rotary compressor according to claim 1, wherein the first and second reed valves have different plate thicknesses. (3) A discharge valve device for a rotary compressor according to claim 1, wherein the numbers of the first and second reed valves are different from each other. (4) A discharge valve device for a rotary compressor according to claim 1, wherein the first and second reed valves have different plate widths. (5) A discharge valve device for a rotary compressor according to claim 1, wherein the first and second discharge holes have different opening areas.
