Rotary compressor

Abstract

Abstract PURPOSE:To enhance the wear-resistance, hermetical sealing and lubrication effect of a compressor, by forming the inner surface of a cylinder with iron group sintered alloy containing therein iron group oxide having a specific percentage, and as well by forming a rotor and vanes with iron group sintered alloy which is obtained by annealing martensite. CONSTITUTION:The inner surface of a cylinder is formed with iron group sintered alloy containing therein 10 to 40 volume % iron group oxide. A rotor 2 and/ of blades 3 are formed with iron group sintered alloy whose base is obtained by annealing martensite, in which metal carbide or metal oxide is diffused and in which nitrogen is solidly dissolved. With this arrangement the wear-resistance and hermetical sealing of the compressor may be enhanced and as well excellent wear-resistance may also obtained due to lubrication.
