Title
(EN) GEAR PUMP FOR MICROVAPORIZER CARTRIDGE
(FR) POMPE À ENGRENAGES POUR CARTOUCHE DE MICROVAPORISATEUR
Abstract
(EN) A pump (34) is configured to pressurize fluid in a microvaporizer (10). The pump includes a chamber (42) bounded by a chamber wall (43) with an inlet opening (55) configured to receive fluid and an outlet opening (57) configured to discharge fluid. The chamber has a circular cross-section. The pump further includes a rotatable impeller (44) positioned within the chamber and a shaft (46) extending through a center of the impeller. The impeller is configured to rotate around the central longitudinal axis of the shaft. In addition, the shaft is offset from the center of the chamber toward the outlet opening and away from the inlet opening so that the axis of rotation of the impeller is offset from the center of the chamber. The pump has a compact design that is able to generate the pressure differential necessary to maintain the flow of fluid and is able to react quickly to meet the demand of the user.
(FR) Une pompe (34) est conçue pour mettre sous pression un fluide dans un microvaporisateur (10). La pompe comprend une chambre (42) délimitée par une paroi de chambre (43) ayant une ouverture d'entrée (55) conçue pour recevoir un fluide et une ouverture de sortie (57) conçue pour évacuer un fluide. La chambre a une coupe transversale circulaire. La pompe comprend en outre une turbine rotative (44) positionnée à l'intérieur de la chambre et un arbre (46) passant par le centre de la turbine. La turbine est conçue pour tourner autour de l'axe longitudinal central de l'arbre. De plus, l'arbre est décalé par rapport au centre de la chambre vers l'ouverture de sortie et à l'opposé de l'ouverture d'entrée de telle sorte que l'axe de rotation de la turbine soit décalé par rapport au centre de la chambre. La pompe a une conception compacte qui est capable de générer le différentiel de pression nécessaire pour maintenir l'écoulement de fluide et peut réagir rapidement pour répondre à la demande de l'utilisateur.
