Abstract
A rotary compressor uses a freon without containing chlorine ions and uses polyol ester as a lubricant or plyvinyl ether as a base oil for providing a highly reliable rotary compressor, and for preventing abnormal abrasion. The rotary compressor has a roller and a vane sliding contact with an outer circumference of the roller. A sliding contact portion between the vane and the roller is formed with a curvature Rv, and satisfies T<Rv<Rr, wherein T is the thickness of the vane and Rr is the curvature of the outer circumference of the roller.

A rotary compressor, coupled to a freon loop connecting in turn to the rotary compressor, a condenser, a expansion device and an evaporator, the rotary compressor using a freon without containing chlorine ions and using polyol ester as a lubricant or plyvinyl ether as a base oil, the rotary compressor comprising:
- a cylinder, having a freon inlet and a freon outlet;
- a rotary shaft, having a crank installed on an axis of the cylinder;
- a roller, installed between the crank and the cylinder, and eccentrically rotating;
- and
- a vane, reciprocating within a groove formed in the cylinder, and sliding contact with an outer circumference of the roller,
- wherein a sliding contact portion between the vane and the roller has a curvature Rv satisfying following formula:
- T<Rv<Rr
- wherein T is the thickness of the vane and Rr is the curvature of the outer circumference of the roller sliding contact with the vane.
