Abstract

1,241,358. Turbines. WESTINGHOUSE ELECTRIC CORP. Oct.6, 1969 [Oct. 30, 1968], No.48987/69. Heading F1T. Working fluid leakage around the segmental inner shroud ring 13 of stator blades 11 in a gas turbine or like machine is reduced by sealing ring segments 42 mounted in an annular groove in a stator member 33 and urged into contact with the shroud ring 13 by leaf springs 46 and by pressurized air bed into the cavity 47 below the segments 42 through openings 71 from a cooling air chamber 21. The gap between the ends of adjacent segments 42 is sealed by a member 57 located in slots 55 in the segments 42 and overlying a further member 61 located in slots 56. Member 57 is secured to one of the segments 42 by a screw passing through the segment and entering hole 63 in the member. Sufficient clearance is provided between the members 57, 61 and the respective slots 55, 56 to permit relative radial movement of the ends of the segment 42. Reference has been directed by the Comptroller to Specification 1,062,660.
