Dynamically balanced co-orbiting scrolls.

摘要

Co-orbiting scroll members (26,28) are maintained in a fixed angular relationship. An anti-rotation structure limits one of the scroll members to orbiting motion with respect to the separator plate (32). In a first embodiment the scroll members (26,28) coact with a common anti-rotation structure (30) while in a second embodiment the other scroll (26) coacts with an anti-rotation structure (130) which coacts with the crankcase (20). The scroll members (26,28) orbit in orbits of different radii.
