Abstract

Dispositif permettant de relier l'enceinte à vide d'un cryostat tournant à une pompe à vide poussé, fixe, chargée de maintenir le vide dans ladite enceinte, comprenant une partie fixe reliée à la pompe à vide, une partie tournante, concentrique à la partie fixe et munie d'un orifice de pompage, et au moins un joint d'étanchéité tournant disposé entre la partie fixe et la partie tournante. Il comporte au moins un clapet 8 qui tourne avec ladite partie tournante 1 et qui, en temps normal, obture l'orifice de pompage 3 de la partie tournante si le vide est correct, et des moyens 19 permettant d'écarter ce clapet de l'orifice de pompage pour mettre en communication enceinte à vide avec la pompe lorsque le vide dans l'enceinte devient insuffisant.
