Kind Code:
A1
Abstract:
[Problem] To reduce imbalance in all components of a movable system including a drive shaft and a component fixed or linked to the drive shaft in a scroll-type compressor. In the scroll-type compressor 10, a shaft balancer 31 integrated with a drive shaft 30 has a first weight part 33 positioned on a side opposite from an eccentric pin 71 with a center line CL0 of the drive shaft 30 therebetween, and a bush balancer 721 integrated with an eccentric bush 72 has a second weight part 723 positioned on the radially outer side of the eccentric bush 72 and on a side opposite from a center line CL1 of the eccentric pin 71 with a center line CL2 of the eccentric bush 72 therebetween. When seen from the axial direction of the drive shaft 30, the second weight part 723 is formed symmetrically with respect to a virtual straight line passing through the center of the drive shaft 30 and the center of the eccentric bush 72, and the first weight part 33 is formed asymmetrically with respect to the virtual straight line.
