要約
(EN)
A pump unit (10) that pumps liquid inside a container body (12) to the outside is provided with a liquid containing portion and a piston portion that is moveably inserted in the liquid containing portion. The piston portion has a shaft case (20) that is provided inside the liquid containing portion and has a female thread portion (20a) formed on an internal circumferential surface thereof, and has a piston head portion (21 and 22) that protrudes outside the liquid containing portion and has a discharge aperture (22c) formed on the protruding portion, and that has a male thread portion (21a) which screws into the female thread portion (20a) formed on an external circumferential surface, and that is inserted into the shaft case so as to be able to move inside the shaft case. An unthreaded portion (20b) that allows the male thread portion of the piston head portion to rotate freely in the circumferential direction of the shaft case is formed on the shaft case. According to this pump unit, it is possible to freely rotate the discharge aperture of the piston head portion separately from the operation to discharge the liquid inside the container body.

(FR)
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.
