Patent ID: 6962486

Claim:
A variable capacity rotary compressor, comprising: a partition plate; a housing installed in a hermetic casing, to define first and second compression chambers therein which are partitioned by the partition plate; first and second flanges mounted to predetermined positions of the first and second compression chambers, to close openings of the first and second compression chambers, respectively; a rotating shaft to pass through the first and second compression chambers and the partition plate; first and second eccentric units mounted to the rotating shaft, to be placed in the first and second compression chambers, respectively, one of the first and second eccentric units being eccentric from the rotating shaft to execute a compression operation while a remaining one of the first and second eccentric units is released from eccentricity from the rotating shaft to execute an idle rotation according to a rotating direction of the rotating shaft, the first and second eccentric units being oppositely operated; and first and second rollers to fit over the first and second eccentric units, respectively, with inside portions of ends of the first and second rollers being spaced apart from inside surfaces of the first and second flanges, respectively, offsetting pressure applied to the ends of the first and second rollers.
