とする多気筒型回転圧縮機。 Cylinders 3 and 4 each have a compression chamber concentric with the crankshaft 6 formed on their inner periphery, and a rolling piston 7 that is driven by an eccentric portion of the crankshaft 6 and rolls along the inner peripheral surface of the cylinders 3 and 4. 8 and vanes 9 and 10 that are brought into pressure contact with the outer peripheries of the rolling pistons 7 and 8 to partition the compression chamber into a high pressure chamber and a low pressure chamber, are connected to the crank via the intermediate partition plate 5. In a multi-cylinder rotary compressor in which a plurality of shafts 6 are arranged in the axial direction, the intermediate partition plate 5 is provided with a crankshaft insertion hole 17 in the center for insertion of the crankshaft 6, and is arranged around the crankshaft insertion hole 17. It is composed of a flat plate divided into two in the radial direction, and the divided positions 14a and 14b are connected to the suction port A of the cylinders 3 and 4 and the vane 9.
