Abstract
An improved guide vane shroud sealing device is disclosed wherein the shroud is formed from a plurality of segments, each segment having interengaging, 'Z' shaped edges. The 'Z' edges each have a mid-portion extending parallel to the rotational plane of a rotor blade wheel, and leading and trailing edge portions extending from this mid-portion to the leading and trailing edges of the shroud segments. A honeycomb packing structure seals the inner surface of the guide vane shroud in conjunction with labyrinth sealing fins on the rotor wheel. The honeycomb structure is oriented such that opposite sides of each cell which are joined to adjacent cells extend at an angle of approximately 60.degree. to the rotational plane of the rotor blade wheel.
