Title:
SCROLL COMPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/127750
Kind Code:
A1
Abstract:
Provided is a scroll compression device that increases the efficiency of the working properties of coil magnetization. A scroll compression mechanism (11), which compresses a refrigerant, and a drive motor (13) that is coupled to the scroll compression mechanism (11) via a drive shaft (15) and that drives the scroll compression mechanism (11) are housed in a casing (3); the scroll compression mechanism (11) is supported in the casing (3) by a main frame (21); the rotor (39) of the drive motor (13) is connected to the drive shaft (15); the drive shaft (15) is supported in the casing (13) by a bearing plate (8); a pickup (45) is connected to an oil supply path (41) that extends vertically within the drive shaft (15); and an interconnection path (38B, 54A), which returns to below the drive motor (13) the lubricant brushed up by the pickup (45) and supplied to lubrication sites, is formed between a stator (37) and a spacer ring (38) or between the spacer ring (38) and the casing (3).
