Abstract

Une pompe comprend un boîtier comprenant un orifice d'entrée pour recevoir un liquide devant être pompé, un orifice de sortie pour fournir le liquide pompé, une chambre de pompage entre l'orifice d'entrée et l'orifice de sortie ; et un arbre de moteur qui tourne dans la chambre de pompage. La turbine est placée sur l'arbre de moteur. Elle comprend : des aubes incurvées radialement qui tournent dans la chambre de pompage pour pomper le liquide, de la chambre de pompage à l'orifice de sortie ; et des aubes anti-poches d'air constituant un ensemble d'extensions d'aubes incurvées axialement qui s'étendent le long de l'axe de l'arbre, tournent avec une partie à l'intérieur de la chambre de pompage, font saillie à travers l'orifice d'entrée et tournent avec une autre partie à l'extérieur de l'orifice d'entrée de sorte à être immergées dans un liquide devant être pompé sous la pompe, aspirer le liquide par l'orifice d'entrée dans la chambre de pompage, et fournir le liquide aux aubes incurvées radialement de sorte à générer une pression pour forcer l'air piégé hors de la chambre de pompage.
