Abstract
A gas turbine includes a change-over valve having a rotatable part and a static part. The valve is disposed between upstream and downstream compressors of the engine for selectively directing flows from the upstream compressor and an auxiliary inlet to the downstream compressor or an auxiliary outlet, the downstream static part of the valve being formed as a structural element of the engine casing from which extends forwardly a support member which carries bearings for supporting the forward rotating part of the valve and the casing of the compressor.
