    摘要: Seal means for reducing the gas flow through the space between the opposing ends of first and second concentric axially disposed cylinders is disclosed. The seal means includes a presizeable annular leaf seal concentrically mateable with the first cylinder. In addition, the seal means includes securing means for securing the left seal to the second cylinder. In a specific embodiment, the seal means provides an effective seal between a turbine rear frame and mixer liner.
