Abstract

Dans un procédé de fonctionnement d'une pompe à vide à joint d'huile, a lieu comme première étape une mesure de la pression totale d'aspiration régnant dans une canalisation d'aspiration (22) de la pompe à vide. Afin de réduire le risque de retour de vapeur d'huile dans une zone sous vide raccordée à la canalisation d'aspiration, la vitesse de rotation de la pompe à vide est régulée en fonction de la pression totale d'aspiration mesurée sur une plage de pressions prédéterminée. L'invention concerne en outre une pompe à vide à joint d'huile, la canalisation d'aspiration (22) de la pompe à vide, reliée à l'espace d'aspiration, étant recourbée immédiatement avant une ouverture d'admission (36).
