Claims

[Scope of utility model registration request]

(1) A cylinder having a compression chamber concentric with the drive shaft formed on its inner circumference, a rolling piston that is driven by an eccentric portion of the drive shaft and rolls along the inner circumference of the cylinder, and an outer circumference of the rolling piston. In a multi-cylinder rotary compressor, a plurality of compressor elements are arranged in the axial direction of the drive shaft with an intermediate partition plate interposed therebetween, and a vane is pressed by a spring to divide the compression chamber into a high-pressure chamber and a low-pressure chamber. , a multi-cylinder rotary type, characterized in that the intermediate partition plate is divided into a large piece part and a small piece part by two dividing lines passing through the drive shaft insertion opening, and the two dividing lines are formed in a non-linear shape. compressor.

(2) Practical use characterized in that the two dividing lines that divide the intermediate partition plate through the drive shaft insertion opening are formed parallel to each other at an interval with a width larger than the outer diameter of the drive shaft. A multi-cylinder rotary compressor according to claim 1 of the patent registration claim.

(3) The multi-cylinder rotary compressor according to claim 1, wherein the small pieces of the divided intermediate partition plate are formed into fan shapes.
