<p>A gas turbine comprises a compressor having an end stage with a radial impeller 2 and a vaned diffusor 3, 20.1, 20.2. The diffusor vanes 3 serve, together with fastening elements 7 to connect diffusor housing members 20.1, 20.2, to connect a guide vane carrier 1 with a rear bearing housing 21. Take-off of compressed cooling air is effected through round bores 6.1 or slots 6.2, which are machined into the suction side of each diffusor vane 3 and which lead to blind bores 19 in the vane 3. The air then passes through bores 19.1 in the diffusor housing member 20.2 and into a cooling air outlet 10 in the compressor housing.</p> |
