Claims

[Scope of utility model registration request]

The rotation of a rotor provided in the housing case expands and contracts vanes disposed on the outer periphery of the rotor, thereby changing the volume of a compression chamber separated by the housing case and a side boob plate constituting a side wall of the housing case. , in a rotary compressor that compresses refrigerant sucked in through a suction hole, a plurality of refrigerant discharge holes are arranged in the side plate, and a connecting groove connecting the ends of these refrigerant discharge holes is formed on the compression chamber side. Characteristic rotary compressor.
