Abstract
Ce dispositif de pilotage de jeux entre un rotor (1) et un stator (2) l'environnant est réalisé en modifiant le débit de soufflage acheminé dans une cavité de rotor (9) pour réaliser un débit de purge qui empêche les gaz de la veine (3) de pénétrer dans la cavité. Une vanne (22) peut fermer partiellement le circuit de soufflage, ce qui diminue le rafraîchissement de la structure de rotor (10) et permet sa dilatation et la réduction des jeux avec le stator (2), pour certains régimes dont les régimes de croisière. Et l'air soufflé s'échauffe plus à débit réduit, surtout si on lui fait emprunter une dérivation (24) pourvue de méandres (26) dans les portions (17) les plus chaudes du circuit.
