Claims

[Claims for Utility Model Registration] (1) A cylinder is formed with a cylinder chamber, a valve port opening into the cylinder chamber and extending radially outward, and a round hole-shaped valve chamber formed parallel to the cylinder chamber. ,
A discharge port that communicates the valve chamber with the outside of the compression element is disposed parallel to the cylinder chamber on the outer peripheral side of the cylinder chamber, and a reed valve that opens and closes the valve port is disposed along the circumferential direction of the valve chamber, In a discharge valve device for a rotary compressor, in which a valve holder is provided in the valve chamber to regulate the opening/closing stroke of the reed valve and to fix one side of the reed valve to the valve chamber wall, the axial direction of the valve chamber is An end hole having a diameter different from the opening/closing part of the valve is formed at one end, and a sealing part that comes into close contact with the boundary between the opening/closing part and the end hole or the receiving part provided in the end hole is attached to the valve holder. A discharge valve device for a rotary compressor, characterized in that the valve holder is formed at one end in the axial direction, and an end wall for closing a gas passage inside the valve holder is formed at the one end of the valve holder. (2) The discharge valve device for a rotary compressor according to claim 1, wherein the sealing portion of the valve holder is brought into close contact with the receiving portion of the valve chamber via a sealing member.
