摘要： A rotary compressor for refrigerating apparatuses, including a motor unit, a compressor mechanism section including a cylinder, rotary piston in the cylinder and a bearing between the motor unit and the cylinder, and a discharge muffler. The discharge muffler is formed of a diaphragm and a discharge cover placed over a surface of the bearing opposite the motor unit, the surface of the bearing covered by the diaphragm having a concavity therein housing a valve leading to the cylinder. The diaphragm has a permanently open diaphragm hole for permitting the pressurized gas therein to flow into a discharge chamber defined between the diaphragm and the discharge cover, whereby the portion of the concavity not filled by the valve and the diaphragm define a muffler for muffling sounds of the compressor.
