Abstract
In a co-rotating scroll apparatus wherein one scroll is a drive scroll and the other scroll is an idler scroll, an axial pressure balancing mechanism and means for discharge pressure balancing is disclosed. The drive scroll wrap is provided with an end plate having a plurality of extension members extending thereform. The extension members extend through corresponding slots in an Oldham coupling ring to drive the idler scroll in relative orbital rotation. The extension members further extend through clearance slots in the end plate of the idler scroll to secure a compression plate and spring biasing the end plate of the idler scroll toward the drive scroll to provide improved axial compliance between the scrolls. Means for axial pressure balancing of the idler scroll shaft and the drive scroll drive shaft are disclosed. The apparatus also includes axial thrust bearings for preventing axial oscillations of the drive and idler scrolls.
