Abstract

L'invention concerne une unité de pompe (10) qui évacue un liquide dans un corps de récipient (12) et possède une partie de réception de liquide ainsi qu'une partie piston insérée mobile dans la partie de réception de liquide. La partie piston comprend une gaine d'arbre (20) montée dans la partie de réception de liquide et possédant une partie de vis femelle (20a) formée à sa périphérie intérieure, ainsi qu'une partie tête de piston (21, 22) insérée mobile dans la gaine d'arbre. La partie tête de piston fait saillie à l'extérieur de la partie de réception de liquide, une partie d'ouverture (22c) est formée dans la partie faisant saillie, et une partie de vis mâle (21a) est vissée dans la partie de vis femelle (20a), à la périphérie extérieure de la partie de tête de piston. A l'intérieur de la gaine de l'arbre on a formé une partie non vissable (20b) permettant à la partie mâle vissable du piston de pivoter librement dans une direction circulaire à l'intérieur la gaine de l'arbre. Dans cette unité de pompe, l'ouverture de sortie de la partie de tête de piston peut pivoter librement, indépendamment du mouvement pendant l'opération de sortie du liquide dans le corps de récipient.
