Abstract
A scroll fluid device is provided with a toothed ring synchronizer coupled to sprocket teeth provided of each scroll wrap back plate. The coupling between the teeth does not restrict relative axial motion between the scroll wraps and evenly distributes torque loads resulting from forces tending to rotate one wrap relative to the other between the back plates. The ring synchronizer may include internal or external teeth cooperating with adjoining sprocket teeth provided on the scroll back plates.
