<p>The adjoining edges of bucket covers (12) are sealed one to the other. A brush seal (18) projecting from a stationary shroud (14) overlies the bucket covers. A joint at which the adjacent covers sealingly engage each other precludes radial outflow of high pressure fluid into bristles (22) of the brush seal, preventing radial and axial deflection of the bristles and consequent failure of the bristles. The joints between the covers may comprise lap (41) or tongue-and-groove joints (74).</p> |
