ABSTRACT:
The diameter of an orbiting scroll plate is increased and the periphery of the plate is notched or scalloped to clear the bolt bosses or spacers located between the fixed scroll and crankcase. The bolt bosses act as guides for the notches in the orbiting scroll plate to thereby create an anti-rotation mechanism. Because the anti-rotation structure is on the periphery of the plate, a greater thrust surface is available.
