Claims

[Claims for Utility Model Registration] (1) A concave groove is formed on the outer periphery of the discharge side of the cylinder at the location where the discharge hole is bored, and an elastic plate member that is displaceable in order to open and close the discharge hole is formed in the groove. A cylindrical discharge valve is attached to the cylinder via a cover that supports a stopper that comes into contact with the inner surface of the discharge valve and suppresses excessive displacement of the discharge valve when the discharge valve is displaced. In the discharge valve structure of the compressor, the stopper is formed in a cylindrical shape made of an elastic plate material, is located on the inner peripheral side of the discharge valve, and is disposed so as to be supported near the inner center part of the cover. A discharge valve structure for a compressor, characterized in that it reduces the impact force that comes into contact with a stopper of the discharge valve. (2) The scope of the utility model registration claim, in which the stopper and the discharge valve have the same shape in the free state, and are supported on the inner surface of the cover so that the respective openings have different expansion distances so as to maintain a predetermined lift. The discharge valve structure of the compressor according to item 1. (3) The discharge valve structure for a compressor according to claim 1, wherein the stopper has a C-shaped cross section and its top is fixed to the central part of the inner surface of the cover.
