WIPO Patent Application WO/2012/127749

A1

Provided is a scroll compression device that can support a greater elimination capacity using a magnetic balancer. 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 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 (3) by a bearing plate (8); a magnetic upper balancer (63) is attached at the top of the drive shaft (15) at a position above a stator (37); a non-magnetic lower balancer (77) is attached to the bottom end of the rotor (39); and a non-magnetic auxiliary balancer (64) is attached at the gap between the top end of the rotor (39) and the upper balancer (63).
