Abstract

In some examples, a co-rotating scroll compressor includes a driver scroll having an axis aligned with the main axis and having a spiral involute; an idler scroll having an axis offset from the main axis and having a spiral involute intermeshed with the spiral involute of the driver scroll; an Oldham coupling disposed between the driver scroll and idler scroll; an idler scroll shaft hub fixed to the lower cap and having an axis aligned with the idler scroll axis and having a drive flat, a hub of the idler scroll is disposed on the idler scroll shaft hub fixed to the lower cap.
