The first and second cylinders 3 and 4 are fixed, and the first cylinder 3 is connected to the cylinder chamber by the upper bearing 7 and the partition plate 9, and the second cylinder 4 is connected to the cylinder chamber by the partition plate 9 and the lower bearing 8. The crankshaft 2 has a first pin part 10 and a second pin part 11, and a first rotor 5 and a second rotor 6 are loosely fitted into each pin part.

るベーンが同一方向に設置されている。 In the rotary compressor configured in this manner, as the crankshaft 2 rotates driven by the motor 12, the gas sucked in from the suction pipe (not shown) is transferred to the first and second cylinders 3, 4, and the rotor 5. , 6, is compressed due to a change in the volume of the cylinder chamber in the space surrounded by the upper bearing 7, the partition plate 9, and the lower bearing 8,
It is discharged to the outside of the compressor from a discharge pipe 13 through a discharge valve (not shown) and a space inside the housing 1, and is normally discharged from the first pin part 10 and second pin part 1 of the crankshaft 2.
The eccentric directions of the cylinders 1 and 1 are 180 degrees apart from each other, and the gas is compressed twice for one rotation of the crankshaft 2. In this case, the first and second cylinders 3 and 4 have vanes (not shown) in the same direction. It is installed in

ス漏れが発生しやすいなどの欠点がある。 However, in order to assemble such a multi-cylinder rotary compressor, it is necessary to divide the crankshaft 2 into two parts, make the pin part 11 a separate part from the crankshaft 2 and press-fit it during assembly, or divide the partition plate 9 into two parts. Alternatively, it is necessary to make the center hole diameter of the partition plate 9 larger than the diameter of the pin part, but it is difficult to maintain the concentricity of the crankshaft 2 when the crankshaft is divided into two parts, so the press-fitting of the pin part is difficult to achieve concentricity of the crankshaft 2. It is difficult to position the partition plate 9 in the circumferential direction with respect to the crankshaft 2, and it is difficult to maintain the flatness of the partition plate 9 by dividing the partition plate into two parts. There are disadvantages such as gas leakage from the gaps.

たことを特徴とする。 The present invention was proposed in view of the above circumstances, and aims to provide a multi-cylinder rotary compressor that is easy to assemble and does not cause gas leakage. If a pin part of the crankshaft into which the cylinders are loosely fitted is formed in common to a plurality of cylinders, and an integral rotor common to the plurality of cylinders is loosely fitted into the same pin part, a rotor which is provided between the plurality of cylinders on the same rotor is formed. A rotor that is slidably and loosely fitted into an annular groove and is integrally formed with a partition plate that partitions each cylinder is used as an integral rotor that is common to each cylinder chamber, and the rotor is provided with a partition plate that partitions each of the cylinder chambers. It is characterized by being fixed.
