Abstract (en)

Provided is a rotary compressor which exhibits a high efficiency without an increase in a suction pressure loss due to reduction in a cylinder width and which can be easily assembled without the difficulty in assembly and manufacturing to ensure concentricity even if a suction port extending across a plurality of components is provided. Also provided is a method for manufacturing the rotary compressor. In a rotary compressor 1, two upper and lower cylinder chambers 9, 11 are formed by an upper cylinder 10, a separator plate 13, a lower cylinder 12, an upper bearing 14, and a lower bearing 15, and a single suction port 24 communicating with the upper and lower cylinder chambers 9, 11 is provided to extend across three components including the upper cylinder 10, the separator plate 13, and the lower cylinder 12.
