A multicylinder rotary compressor capable of performing highperformance 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 comprises a rotary compressing element housed in a hermetic enclosure; wherein the rotary compressing element is equipped with an intermediate partition plate, cylinders provided on both sides of the partition plate, a rotary shaft having eccentric sections which are shifted against each other by 180 degrees in the angle of rotation, rollers which are fitted onto the eccentric sections of the rotary shaft and which rotate in the cylinders, and bearings which seal the openings of the cylinders. The multicylinder rotary compressor further comprises first apertures provided in the inner walls of the two cylinders, second apertures provided in the two cylinders so that they communicate with the first apertures, and a third aperture provided in the intermediate partition plate so that it communicates with the two second apertures; wherein a gas which is being compressed in one cylinder is allowed to flow, via the first, second, and third apertures, into the other cylinder which is in an intake stroke. <IMAGE> |
