Abstract
Means for preventing the wasteful leakage of cooling air within the turbine section of a gas turbine engine is disclosed. A segmented shroud radially separates the flow path for the working medium gases from cooling air supply chambers which are disposed radially outward of the flow path. Rotatable vanes penetrate the shroud and extend into the medium flow path to control the flow of medium gases through the turbine. A ring, which is split, is urged against the vane and the adjacent shroud segments in operative response to a spring member to prevent the excess leakage of cooling air therebetween.
