ABSTRACT:
A stator assembly 20 for a rotary machine 10 includes an outer case 22 and an inner case 56 which is positioned from the outer case. The inner case is formed of segments 76 which overlap and which are relatively slidable in the circumferential direction. Various construction details are developed to keep the segments in an overlapping relationship. In one embodiment, a fastener 104 and slot 102 configuration are used to limit relative circumferential movement between the segments.
