Claims

[Scope of utility model registration request]

A motor element and a compressor element connected by a drive shaft are housed in a sealed container, and the compressor element has a rolling piston driven by the drive shaft in a cylindrical cylinder, and a rolling piston that contacts the rolling piston and moves inside the cylinder. A vane is provided to partition the suction side and the compression side, and a frame and cylinder head are attached to both ends of the cylinder to seal the cylinder and bear the drive shaft, as well as a discharge hole for discharging the compressed gas and a discharge hole for opening and closing this discharge hole. In a rotary compressor in which a valve device is provided in any one of a cylinder, a frame, and a cylinder head, a discharge muffler is provided that covers the frame so that a bearing portion projects and communicates with the discharge hole and the discharge valve device, and the discharge muffler is provided to communicate with the discharge hole and the discharge valve device. A rotary compressor characterized in that a petal-shaped muffler discharge hole is provided around a bearing part of a frame of the muffler.
