Title (EN) SELF-DRIVEN PUMP DEVICE
(FR) DISPOSITIF DE POMPAGE AUTOMATIQUE
Abstract:
(EN) An apparatus for delivering fluid with a relatively constant, controlled rate of flow comprises a vacuum power means (11), a fluid storage means (12) in axial alignment with the vacuum power means and a plunger means (21) carried by the vacuum power means and in axial communication with the fluid storage means. The plunger means is driven by a vacuum which collapses under atmospheric pressure, and as it is driven it effects delivery of the fluid from the fluid storage means.
(FR) Un appareil d'acheminement de fluide à un débit régulé relativement constant comprend un moyen (11) de commande à vide, un moyen (12) de stockage de fluide en alignement axial avec ledit moyen de commande à vide, ainsi qu'un moyen (21) de plongeur porté par le moyen de commande à vide, et en communication axiale avec le moyen de stockage de fluide. Le moyen de plongeur est commandé par un vide, lequel s'infléchit sous l'effet de la pression atmosphérique, et à mesure qu'il est commandé, il achemine le fluide à partir du moyen de stockage de fluide.
