Abstract

La présente invention concerne une pompe d’aspiration capable de refouler un liquide à un endroit situé plus haut qu’un orifice de refoulement ou à un endroit situé loin de l’orifice de refoulement en mettant l’eau sous pression dans la pompe avec une structure simple et économique sans nuire à une fonctionnalité qui fait qu’une force exigée pour faire monter l’eau par pompage peut être réduite en exploitant la flottabilité. La pompe d’aspiration (10) comprend un tube externe creux (20) possédant un orifice d’aspiration (23) et un orifice de refoulement (24) et une tige de va-et-vient creuse (30) introduite dans le tuyau externe et pouvant effectuer un va-et-vient. Un dégagement servant à faire passer l’eau est formé entre la surface interne du tube externe et la surface externe de la tige de va-et-vient. Quand la tige de va-et-vient (30) qui comprend un piston (34) avec un orifice d’aspiration (40) et un clapet de décharge (38) installés sur le piston, est déplacée verticalement, le liquide pompé est mis sous pression pour le faire monter à n’importe quelle hauteur dans un sens facultatif par un clapet anti-retour (50) installé au niveau de l’orifice de refoulement (24).
