Abstract

La présente invention concerne un réservoir d'encre pour une imprimante à jet d'encre comportant un orifice de sortie d'encre, un évent, une cavité de fourniture d'encre et une chambre enceinte d'encre. L'évent qui se trouve au sommet de la première chambre d'encre dans une direction perpendiculaire relie la première chambre d'encre à l'atmosphère. L'orifice de sortie d'encre qui est sur une paroi perpendiculaire de la cavité de fourniture d'encre à proximité de la base relie la cavité de fourniture d'encre à l'extérieur. Un premier tube d'encre est disposé horizontalement au-dessus d'une position centrale de la cavité de fourniture d'encre dans la direction perpendiculaire. La première extrémité du tube est reliée à la cavité de fourniture d'encre, et la seconde extrémité s'étend vers le bas dans la direction perpendiculaire pour être reliée à la première chambre d'encre à une position qui est inférieure à la première extrémité du tube. Une cartouche d'encre avec une pluralité de chambres peut être obtenue par l'augmentation additionnelle du nombre de chambres d'encre. La structure du réservoir d'encre est simple, et permet d'éviter la perturbation de gaz dans chaque chambre d'encre lors du stockage et du transport.
