Abstract
A scroll-type compressor having a unique coupling arrangement for driving the movable scroll is provided. The side of the base portion of the movable scroll opposite the spirals has a plurality of recesses disposed in a circular pattern. A support plate having a plurality of complementary recesses therein is positioned such that its recesses face the recesses in the movable plate. The diameters of the first and second recesses are different from one another. Coupling members are disposed between each facing pair of recesses. The coupling member has small and large diameter portions. The small diameter portion extends into its associated smaller recess while the large diameter portion extends into its larger associated recess. With this arrangement, the required width of the recess bearing portion of the support plate may be reduced relative to conventional designs which has several advantages.
