The roller 8 is pressed against the outer periphery of the roller 8 by the pressure applied to the back of the vane and moves while sliding at the contact point. The lubricating oil at the sliding point is mainly lubricated by the oil mixed into the suction gas. The suction gas entering the suction pipe 15 circulates through the refrigerant cycle together with the refrigerant gas. Although the refrigerating machine oil 18 is contained in a small amount, the amount at this level causes a boundary circulation state close to metal contact, and severe sliding conditions are particularly required in the HFC where the sliding property of the refrigerant is not expected.

In addition, the vane body portion 19 of 0 is made of an iron-based sintered material, and the components are 0.6 to 1.3% of carbon, 3.4 to 4.8% of chromium, 3.6 to 5.5% of molybdenum, and 1.0% of vanadium. 4-3.0

Using 0% tool steel powder, the sintering density of the vane tip 20 and the vane body 19 is 6.0 to 7.4 g / cm 3 , and the joining portion 21 of the vane tip 20 and the vane body 19 is used.
Are joined by silver-copper-zinc-nickel silver solder, and the roller 8 is made of 0.7% chromium, 0.04% boron, and 0.1% nickel.
It is assumed that the cast iron is made of gray cast iron containing 2% and 0.2% molybdenum and heat-treated, and the cylinder 7 is made of a mold eutectic graphite cast iron and contains 20 to 50% of pearlite. I do. In the above-described operation state, the vane 10 reciprocates in the through groove 9 of the cylinder 7 while receiving pressure. Due to the reciprocating motion, an oil film is unlikely to be formed on the through groove 9 of the cylinder and the side of the vane, resulting in severe sliding conditions. As described above, the sliding condition between the tip of the vane 10 and the outer peripheral surface 22 of the roller 8 is close to the metallic contact with a small amount of oil. Since the vane tip portion 20 of the vane 10 contains a large amount of tungsten and vanadium components having good wear resistance and contains pores having good wear resistance, the vane tip portion 20 can be used even under severe sliding conditions. The tip portion 20 has an effect of reducing adhesive wear on the outer peripheral surface 22 of the roller 8. Further, chromium, boron and molybdenum in the components of the roller 8 are very excellent in wear resistance, and nickel is very excellent in hardenability.
The combination of the roller 8 and the roller 8 results in a material combination having extremely excellent wear resistance. Further, when the cylinder 7 contains 10% or more of pearlite, the abrasion resistance of the vane 10 and the cylinder 7 is significantly improved. From the above, a highly reliable compressor can be realized.
