Abstract
A scroll compressor (10), comprising a fixed scroll (150), a movable scroll (160) and a drive shaft (30); the scroll compressor (10) further comprises a movable scroll counterweight (40); the movable scroll counterweight (40) is configured to rotate with the drive shaft (30); and the centrifugal force of the movable scroll counterweight (40) caused by the rotation acts on the hub (162) of the movable scroll (160). The above structure can effectively reduce the impact of the centrifugal force of the movable scroll on the radial seal of a scroll component, thus achieving proper radial sealing force between the fixed scroll and the movable scroll at any rotating speed.
