Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JP3172337
Kind Code:
B2
Abstract:
PURPOSE: To realize a compressor provided with an improved roller congenial to a vane even with HFC group fleon as refrigerant so as to reduce the mutual wear of the sliding face and able to stand long-term operation.
CONSTITUTION: A roller 2 is formed of a continuously-cast cast iron alloy composed of T.C: 2.0-3.9, Si: 2.0-3.0, Mn: 0.3-1.0, S: 0.01 or less, V: 0.50 or less, P: 0.3-1.0, Sb: 0.01-0.5 at a weight composition ratio and the rest composed of Fe. In addition, it is desirable to contain B: 0.001-0.5. P, Sb and B controlled to the optimum composition improve the wear resistance of the roller 2 with a leap, and moreover this has an effect of also reducing the wear of a vane 1.
