摘要：
A discharge valve is incorporated into a scroll compressor for use in a refrigerator or an air conditioner. A valve element seating surface having a concave cylindrical shape is formed in the upper surface of the stationary disk of the stationary scroll plate of the scroll compressor, a discharge port is formed through the stationary disk of the stationary scroll plate so as to open in the valve element seating surface, and a discharge valve element having a cylindrical shape conforming to the concave cylindrical shape of the valve element seating surface is seated on the valve element seating surface so as to open or close the discharge port. The valve element seating surface having a concave cylindrical shape facilitates machining the stationary scroll plate, reduces the top clearance of the scroll compressor without reducing the rigidity of the stationary disk, prevents the concentration of stress on the delivery valve, and improves the reliability of the delivery valve.
