Claim Text:
1. A sealing assembly comprising a support having a support-seal surface, an engine component having a component-seal surface, the engine component mounted so that the component-seal surface is arranged in spaced-apart confronting relation with the support-seal surface to define a gap between the support and the engine component that grows and shrinks based on the temperature of the support and the engine component, and a seal adapted to block gasses from passing through the gap between the support and the engine component, the seal including a mount ring coupled to the support and spaced apart from the engine component, a ceramic tadpole gasket having a compressible head held in contact with the engine component by the mount ring and a flat body extending from the compressible head into a retention channel formed by the mount ring, and a retainer ring arranged to extend into the retention channel of the mount ring to trap the flat body of the tadpole gasket in the retention channel formed by the mount ring so that the tadpole gasket is coupled to the mount ring, wherein the mount ring includes a spring portion having a U-shaped cross-section and the spring portion is configured to push the compressible head of the ceramic tadpole gasket into contact with the engine component, the U-shaped cross-section of the spring portion included in the mount ring having legs that extend generally parallel to the component seal surface of the engine component.
