ABSTRACT:
Co-orbiting scroll members are maintained in a fixed angular relationship. Each of the scroll members coacts with a common anti-rotation structure which controls orbiting motion between the scroll member. A second anti-rotation structure limits one of the scroll members to orbiting motion with respect to the crankcase. The scroll members preferably orbit in orbits of different radii.
