Filed:

Oct 7, 1974

Appl. No.:

5/513001

Inventors:

Frank Michel - Swarthmore PA
Egidio J. Ruffini - Havertown PA

Assignee:

Westinghouse Electric Corporation - Pittsburgh PA

International Classification:

F01D 902
F01D 904

US Classification:

415217

Abstract:

A seal is provided between adjacent stationary annular shroud members in a gas turbine. The shroud members have an axially directed gap disposed between their adjoining ends. Each adjoining end of each stationary shroud has a shoulder arrangement which provides support for a seal disposed across the gap. The shoulders on the ends of the shrouds provide restraint against radially inwardly directed dislocation, and a blade ring which supports the shroud members themselves, provides restraint against axial and radially outwardly directed dislocation. The seal prevents escape of hot motive fluid from the generally axially directed working fluid flow path.

Abstract:

A slidable seal is disposed in one end of each stationary arcuate shroud segment in a gas turbine. The seal is forced by a spring across a gap between adjacent shroud segments, to abut against an end of an adjacent shroud segment. The slidable seal helps control fluid leakage in both the axial and the radial direction.
