Abstract
A scroll compressor includes a hermetic shell which has a partition defining a discharge pressure chamber and a suction pressure chamber within the shell. The partition includes a surface which pilots the non-orbiting scroll to allow for limited axial movement of the non-orbiting scroll. Rotational motion of the non-orbiting scroll is prohibited by a stationary pin which extends from the partition to engage an extension of the slot which is utilized by the Oldham coupling.
