ABSTRACT:
A multicylinder rotary compressor capable of performing high performance capacity control operation without the need for an external piping or for a thicker partition plate which leads to a taller rotary compressing element or a longer bearing span of a bearing. The multicylinder rotary compressor has a rotary compressing element housed in a hermetic enclosure; wherein the rotary compressing element is equipped with an intermediate partition plate, a cylinder provided on each side of the partition plate, a rotary shaft having eccentric sections which are shifted relative to each other by 180 degrees in the direction of shaft rotation, rollers fitted onto the eccentric sections of the rotary shaft and which rotate in the cylinders, and bearings which seal the cylinders. A first aperture is provided in the inner wall of each of the two cylinders, a second aperture is provided in each of the two cylinders to communicate with the respective cylinder first aperture, and a third aperture in the intermediate partition plate to communicate with the two second apertures. A gas which is being compressed in one cylinder flows, via the first, second, and third apertures, into the other cylinder which is in an intake stroke.
