Abstract
L'invention entre dans le domaine des turbines à vapeur. Dispositif d'échappement pour turbine axiale à fluide condensable comportant un diffuseur annulaire à entrée axiale et sortie sensiblement radiale situé à la sortie du dernier étage de la turbine, et un condenseur compartimenté en deux zones dont l'une est à une pression plus faible que l'autre, caractérisé en ce que la paroi du diffuseur extérieure au flux d'entrée dans le canal comporte une fente circonférentielle évacuant, au moyen de capacités et de gaines de liaison une fraction du débit entrant dans le diffuseur vers la zone à plus basse pression du condenseur, ladite paroi ayant en outre un tracé tel que le gradient de pression, mesuré à sa surface dans le sens de l'écoulement, soit en tout point négatif ou nul. L'invention s'applique en particulier pour les turbines à vapeur de très grande puissance.
