PURPOSE:To prevent resolution of coolant and obtain a compact and a highly efficient rotary compressor, by forming a vane of the rotary compressor to compress a coolant including bromine elements, of a carbon with a metal melted and impregnated therein. CONSTITUTION:A vane 7 of a rotary compressor which uses a coolant containing bromine elements, R13B1 or the like, is formed of a carbonic material with a metal such as aluminum melted and impregnated therein. As a result, the temperature of the vane 7 does not rise so much owing to a self-lubrication of the carbonic material and a thermal radiation of aluminum, preventing to promote a resolution or the like of the coolant gas. Moreover, since carbon has no catalystic reaction, the resolution of the coolant can be also controlled from this respect. |
