Abstract

a. L'invention concerne un tube à rayons X. b. Des conduits radiaux d'admission 7 et des conduits radiaux d'évacuation 9 sont reliés entre eux par une pièce de liaison transversale 10, et le système des conduits d'admission et le système des conduits d'évacuation sont reliés entre eux par des éléments de conduites Il disposés dans l'anode tournante; entre un moyen d'étanchéité radial 22 et la chambre à vide poussé 3 est disposée une turbopompe moléculaire à couronnes alternées d'aubes rotoriques 24 daubes statoriques 25; l'arbre d'entraînement 1 coïncide avec l'axe de rotation du rotor de la turbine relié à l'arbre d'entraînement et entraîné avec ce dernier; le stator est relié avec l'enveloppe et le côté aspiration de ladite turbopompe est situé du côté de la chambre à vide poussé 3 alors que l'enveloppe porte un raccord 27 pour la conduite d'évacuation pour les gaz. c. Application à la radiologie.
