Abstract
A seal means for confining cooling air to a cooling air flowpath extending between a case structure and a flowpath for hot working medium gases in a gas turbine engine is disclosed. Various construction details which enable the seal means to block the leakage of cooling air into the working medium flowpath are discussed. The seal means has a center section which expands axially in response to the temperature of the working medium gases to develop a sealing force.
