Title:
MULTIPLE-CYLINDER ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/155938
Kind Code:
A1
Abstract:
Provided are: a multiple-cylinder rotary compressor which is configured so that the deflection of a rotating shaft is reduced and so that a mechanism for supporting the rotating shaft is simplified; and a refrigeration cycle device.
A multiple-cylinder rotary compressor is provided with a compressor body formed by housing within a hermetic case a rotating shaft, an electric motor section, and a compression mechanism body. The compression mechanism body has: at least three compression mechanism sections which are arranged stacked on each other in the axial direction of the rotating shaft; partition plates which are each arranged between adjacent compression mechanism sections; and a primary bearing and a secondary bearing, which support the rotating shaft at both end sides of the compression mechanism body in the axial direction of the rotating shaft. The compression mechanism sections each have: a cylinder in which a cylinder chamber is formed; an eccentric section which is provided to the rotating shaft and which is installed within the cylinder chamber; a roller with is fitted to the eccentric section and which eccentrically rotates within the cylinder chamber; and a blade which divides the inside of the cylinder chamber into two parts. At least one of the partition plates constitutes a partition plate bearing for supporting the rotating shaft.
