Patent ID: 7153109

Claim:
A variable capacity rotary compressor, including a hermetic casing, a housing installed in the hermetic casing to define therein first and second compression chambers having different capacities, and a compressing unit placed in the first and second compression chambers, and operated to execute a compression operation in either the first or second compression chamber according to a rotating direction of a rotating shaft which drives the compressing unit, the variable capacity rotary compressor comprising: a suction path controller to control a refrigerant suction path so that a refrigerant is delivered into an inlet of the first or second compression chamber where the compression operation is executed; a high-pressure pipe to couple an outlet side of the compressor to the suction path controller; and a high-pressure path controller provided at a predetermined portion of the suction path controller, the high-pressure path controller controlling a high-pressure path so that the high-pressure pipe communicates with the inlet of the first or second compression chamber where an idle operation is executed, according to variance of temperature when the refrigerant suction path is controlled by the suction path controller.
