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, and an Oldham coupling disposed between the driver scroll and idler scroll. The driver scroll may offset key slots so to engage with corresponding Oldham coupling keys. In another example, the Oldham coupling may offset driver scroll keys so to engage with corresponding key slots of the driver scroll.
