ABSTRACT:
A vane rotary compressor wherein at least the rotor, side blocks and vanes are formed from Si-Al alloy materials, respectively, the rotor and the side blocks or the rotor and the vanes differ from each other by more than 3% in terms of their silicon content. Thus, the compressor has improved wear resistance, seizure resistance, compression performance and durability.
