Abstract

Machine comportant un dispositif déflecteur pour empêcher tout écoulement gênant de gaz réfrigérant Elle comprend une série de barres élastiques 36 supportant une série de barres profilées en tenon 34 qui supportent un noyau de stator, et une série de déflecteurs 50, chaque déflecteur étant placé sur chacune des barres élastiques comprises entre les premiers 18 et les seconds 20 passages du stator et comportant une partie située entre la barre élastique et le noyau pour arrêter le flux du gaz réfrigérant entre le noyau et la barre élastique tout en réduisant la transmission des vibrations du noyau au châssis 30 de la machine. Application aux turbo-générateurs.
