Abstract

a. Dispositif pour le support des rotors à haut régime des turbomachines, en particulier des moto-propulseurs à turbine à gaz. b. Dispositif caractérisé en ce que, pendant le service de la turbomachine, de l'huile est introduite sous pression dans les espaces intermédiaires 7, 8 prévus pour le jeu radial entre les chemins de roulement extérieurs et le logement de la machine. c. L'invention s'applique aux turbines à gaz.
