Abstract (en)
[origin: EP2719867A1] The housing structure comprises an outer housing wall (1) and an inner housing wall (2), which annularly enclose a flow channel of the turbo-engine, and are spaced apart relative to the flow channel. A heat shield (6,7) is arranged between the inner housing wall and the outer housing wall. A bar (4) partially protruding in radial direction or a holder partially projecting in radial direction are arranged on the inner housing wall. The bar or the holder comprises a broadening element (5) on one side, which has a sealing surface (8), against which the heat shield rests in a sealing manner.
