Abstract
The multiple cylinder rotary compressor includes a compressor body including a hermetic case, the hermetic case housing inside a rotating shaft, an electric motor section, and a compression mechanism body. The compression mechanism body includes at least three compression mechanism sections which stack with each other, partition plates between the corresponding adjacent compression mechanism sections, and a primary bearing and a secondary bearing supporting the rotating shaft on both end sides of the compression mechanism body. The compression mechanism sections include a cylinder forming inside a cylinder chamber, an eccentric section provided to the rotating shaft, disposed in the cylinder chamber, a roller fitted to the eccentric section, rotating eccentrically within the cylinder chamber, and a blade dividing the inside of the cylinder chamber into two. At least one partition plate constitutes a partition plate bearing supporting the rotating shaft.
