Abstract
Dispositif pour faire le vide du type éjecteur. Le dispositif pour faire le vide 10 selon la présente invention comprend une soupape de commande 73 soumise à des forces d'amortissement et de friction qui varient en fonction des variations de la différence de pression régnant dans le dispositif agissant sur un élément 87 de telle sorte que la soupape peut se déplacer rapidement entre des positions ouverte et fermée évitant ainsi l'étranglement du fluide moteur. Application à un dispositif pour faire le vide du type éjecteur créant une perturbation minimale dans la circulation du fluide moteur.
