Claims

[Claims for Utility Model Registration] 1. A cam ring whose both sides are closed with side blocks, a rotor rotatably disposed within the cam ring, and a rotor that moves forward and backward into a groove formed in the radial direction on the circumferential surface of the rotor. A vane that is freely fitted and whose tip can slide against the inner circumferential wall of the cam ring is provided, and the refrigerant is compressed by changing the volume of the compression chamber defined by the side block, rotor, and vane. In the rotary compressor, a communication hole is provided in one of the side blocks to communicate the compression chamber and the low pressure side, and a relief opens the communication hole only when the pressure of the refrigerant in the compression chamber rises to a predetermined pressure or more. A rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary rotary engine having a valve disposed therein. Compressa. 2. Claims for registration of a utility model characterized in that the communicating hole is provided between the position of the vane on the front side in the rotational direction at the start of inter-vane compression and the position of the vane on the rear side in the rotational direction at the end of inter-vane compression. The rotary compressor described in item 1.
