Document Type and Number:

WIPO Patent Application WO/2014/156679

Kind Code:

A1

Abstract:

In this multi-cylinder rotary compressor, a motor, and a compression mechanism driven by the motor are provided inside a sealed container. The compression mechanism is formed from rotary compression mechanisms (6A, 6B) provided with: a plurality of cylinders (17, 18); a partition plate (21) which forms a partition between the plurality of cylinders (17, 18); blades which partition the insides of the cylinders (17, 18) into intake sides and discharge sides; and rotors (24, 25) which rotate inside the cylinders (17, 18). When ΦMo represents the core diameter of the motor, ΦDc represents the internal diameter of each of the cylinders (17, 18), Hc represents the width of each of the cylinders (17, 18), and Hs represents the width of the partition plate (21), Hs/Hc ≤ 0.35 is satisfied under conditions in which ΦDc/ΦMo ≥ 0.49.
