(1)項または第２項記載のロータリ式圧縮機。[Claims for Utility Model Registration] (1) A plurality of discharge ports are formed along the axial direction of the cylinder chamber, and a valve chamber communicating with these discharge ports is formed in a wall surrounding the cylinder chamber in parallel with the cylinder chamber. A discharge valve consisting of a reed valve provided in a cylindrical shape and capable of freely opening and closing the discharge port is disposed along the circumferential direction of the valve chamber, and further, one end of the discharge valve is attached to a wall surrounding the valve chamber. The gas compressed in the cylinder chamber pushes the discharge valve open, enters the valve chamber through the discharge port, flows in the axial direction of the valve chamber, and the gas compressed in the cylinder chamber pushes the discharge valve open. In a rotary compressor having a discharge valve device that discharges gas to gas holes provided in a cylinder head or frame located on both end faces of a cylinder chamber, the discharge valve device has a cross-sectional area of a plurality of discharge ports and a A rotary rotary system characterized in that at least one of the opening heights of the discharge valves that open and close the discharge ports is made different from each other according to the distance from the gas hole side so that the operation of the discharge valves closer to the gas hole side is stabilized. type compressor. (2) The rotary compressor according to claim 1, wherein the plurality of discharge valves have a larger cross-sectional area closer to the gas hole side. (3) The discharge valve that opens and closes the discharge port has a valve holder shaped so that the opening height becomes lower as it approaches the gas hole.
The rotary compressor described in item (1) or item 2.
