| 摘要 |
The invention relates to a turbomachine of axis X and comprising, from upstream to downstream, a high pressure compressor whose rotor presents a downstream cone ( 4 ), a diffuser ( 3 ) extending downstream beside the axis X by an inner casing ( 5 ) disposed radially outside said downstream compressor cone, a combustion chamber disposed radially outside said inner diffuser casing, and a high pressure turbine whose rotor is connected to the downstream cone of the compressor by a connection drum, the inner diffuser casing and the downstream compressor cone defining between them an under-chamber cavity that is situated downstream from a discharge labyrinth ( 13 ) in which cooling air flows downstream, the turbomachine being characterized in that it also comprises a stator shroud ( 20 ) that is installed under the inner diffuser casing ( 5 ) downstream from the discharge labyrinth ( 13 ).
