ABSTRACT:
A rotary compressor comprises a housing having a cylindrical inner wall surface, a rotatable sleeve having an inner and outer surfaces and disposed in the housing for rotation about a first longitudinal axis, a rotor disposed in the sleeve for rotation about a second longitudinal axis which is offset from the first longitudinal axis, a plurality of vanes carried by the rotor to extend substantially in radial directions and having radially outer edges maintained in contact with the inner surface of the sleeve so that the sleeve is rotated as the rotor and the vanes rotate. One or each of the inner wall surface of the housing and the outer surface of the sleeve has a coating comprised of a wear-resistant resin dispersed with 10 to 120 volume part of a solid lubricant and 5 to 50 volume part of metal flakes for 100 volume part of the resin.
