ABSTRACT:
A variable rotary compressor with a capacity being variable as desired includes a drive device generating a rotating force, a rotating shaft connected to the drive device at a first end thereof and rotated by the drive device, and a cylinder through which a second end of the rotating shaft passes. Two or more compressing chambers are provided in the cylinder such that the two or more compressing chambers are sequentially arranged along an axial direction of the rotating shaft. Rollers are eccentrically installed on the rotating shaft such that the rollers are arranged, respectively, in the two or more compressing chambers. A one-way clutch is installed on the rotating shaft to selectively transmit the rotating force to at least one of the rollers in accordance with a rotating direction of the rotating shaft. During operation of the rotary compressor, only one of the rollers is selectively rotated.
