Abstract
Axial separation of the scrolls 10, 12 in a positive apparatus of the scroll type is resisted by provision of a elongated, tension rod 44. Hollow shafts 20, 24; 30, 32 coupled to the scrolls 10, 12 receive opposed ends 46, 48 of the rod 44 which are fixedly secured thereto in nonrotatable relation. The rod 44 extends through the interface 14 between the scrolls 10, 12 via apertures 26 and 40 and resists axial separating forces present at the interface 14.
