Claims

[Scope of utility model registration request]

The compressor body driven by an electric motor is housed in a sealed container with lubricating oil sealed in the bottom.A muffler is attached to the flange of the lower bearing that closes the bottom end of the cylinder of the compressor body. In a rotary compressor that discharges refrigerant gas into a muffler chamber and then out of a sealed container, an O-ring insertion groove is provided on the outer circumferential surface of the flange portion and the outer circumferential surface of the boss portion of the lower bearing, respectively. A rotary compressor characterized in that an O-ring made of synthetic resin such as PTFE or rubber, which has excellent heat resistance and refrigerant resistance, is inserted to seal the upper end and lower end of the muffler. .
