Abstract

L’invention concerne un récipient pour éliminer les bulles présentes dans un fluide. Le récipient comprend un orifice d’entrée de fluide pour recevoir le fluide et un orifice de sortie de bulles pour éliminer du récipient les bulles présentes dans le fluide. Un ou plusieurs transducteurs ultrasonores transmettent un ou plusieurs faisceaux ultrasonores à travers le fluide reçu pour déplacer les bulles présentes dans le fluide vers l’orifice de sortie de bulles. Un orifice de sortie de fluide libère le fluide insonifié par le ou les faisceaux ultrasonores. Une structure de conduit transporte le ou les faisceaux ultrasonores à travers le récipient dans une première direction vers la sortie d’air. Une interface empêche la réflexion du ou des faisceaux ultrasonores dans une direction généralement opposée à la première.
