Abstract

L'invention a pour objet de réaliser un dispositif pour pomper un fluide d'aspiration avec un fluide propulseur, qui permet de contrôler le débit du fluide propulseur et du fluide d'aspiration. La commande doit notamment permettre d'inhiber entièrement, au choix, le débit du fluide propulseur et du fluide d'aspiration ou seulement du fluide d'aspiration. La solution est basée sur l'idée de fermer temporairement un clapet anti-retour dans la conduite d'aspiration pour le fluide d'aspiration au moyen du fluide propulseur. L'inhibition du refoulement du fluide propulseur et du fluide d'aspiration s'effectue par la fermeture d'une vanne d'arrêt dans le trajet d'écoulement entre l'entrée du fluide propulseur et la sortie du dispositif.
