A cylinder is provided with a main bearing and a sub-bearing to define a cylinder chamber therein, a roller is provided in the cylinder chamber so as to be eccentrically rotatable, and the cylinder chamber is divided into a suction chamber and a compression chamber. What is claimed is: 1. A rotary compressor provided with a blade that partitions the compression chamber, the rotary compressor comprising a noise reduction volume that opens into a compression chamber on the discharge side of the cylinder and on the discharge side side of the blade. 2. The rotary compressor according to claim 1, which is a registered utility model and is provided with noise reduction volumes on both sides of the discharge side of the cylinder. 3. The noise reduction volumes provided on the discharge side of the cylinder and the discharge side side of the blade have different volume dimensions, and each reduces noise in different frequency bands.Claim 1 of Utility Model Registration
The rotary compressor described in section. 4. The rotary compressor according to claim 1, wherein the noise reduction volume is formed by molding.
