とする回転式圧縮機。 A compression chamber is formed by a cylinder, upper and lower bearings that close the upper and lower surfaces of the cylinder, and a rolling piston that rotates within the cylinder and receives rotational force from the crankshaft supported by these bearings. A rotary compressor in which the cylinder is provided with a power save port that opens into the compression chamber and releases partially compressed gas to the low pressure side, and a power save valve mechanism that opens and closes this power save port. In the valve of the valve mechanism,
A rotary compressor characterized in that a convex portion having a smaller diameter than the port diameter is formed to fit into the power save port during normal operation.
