Abstract

The guide vanes 16 are fixedly supported at their tip portions to an outer shroud 12 while the root portion 20 of each vane is connected to a segment 32 of a radially inner, segmented shroud. Each segment 20 is, in turn, connected via a slip fit interconnection permitting thermal expansion to an L-shaped radially inner ring support structure 40. A spring 70 extends between the segment 20 and the base 42 of the L-shaped support to form a flexible coupling, while the remaining portion of the L-shaped support defines a pressure dam to reduce leakage through the flexible coupling. <IMAGE>
