ABSTRACT:
A moving vane type compressor has a cylinder which is made of a sintered material having a density of 6.6 to 7.6 and a composition consisting essentially of 0.6 to 0.8% of carbon, 1 to 2% of copper and the balance substantially iron. The cylinder is encased by a hermetic casing therebetween a high pressure chamber into which a refrigerant compressed by the compressor is discharged. Lubricating oil separated from the discharged refrigerant within the high pressure chamber and the lubricating oil suspended in the form of a mist by the refrigerant attach to the outer peripheral surface of the wall of the cylinder made of the sintered material. The oil attaching to the outer peripheral surface of the cylinder is forced by the refrigerant pressure acting thereon into the pores of the sintered material such as to block these pores, thus preventing the compressed gas in the cylinder from leaking outside through the pores.
