Since the one-way control valve 1 is disposed outside the ink storage chamber 2 ⁇ ;, basically, the ink can be filled in all the chambers, which effectively increases the total amount of ink. See Figure 2. It uses an umbrella-shaped valve body 22 to buckle the through hole 25 communicating with the ink storage chamber 24 from the ink introduction chamber 26. Therefore, during assembly and use, the valve body 22 can be used to hold the ink first. When the print head is ejected, a negative pressure is generated in the ink introduction chamber 26.

Abstract

L'invention concerne une cartouche ainsi qu'un dispositif et un procédé associés de remplissage. Un corps de soupape est placé dans le réservoir d'encre de la cartouche et comprend une base de support ; une paroi de support qui s'élève oblique depuis le côté intérieur de la base de support ; un épaulement de support qui s'étend incurvé en direction du côté intérieur ; et une tête de support qui s'étend vers le haut depuis l'épaulement. Le centre est perforé d'un orifice traversant qui est scellé par un dispositif de scellement du corps de la soupape qui tient donc lieu de conteneur d'encre liquide. Une pièce d'étanchéité placée au niveau de l'ouverture de décharge de l'encre comprend un support qui épouse parfaitement la forme de l'ouverture de décharge. On prévoit également une bague d'étanchéité qui s'élève à partir du support et qui est accouplée à une butée ainsi qu'une pièce de raccord venant entre la bague d'étanchéité et la butée. Grâce à la conception en escaliers annulaires de la structure du corps de soupape de la cartouche, l'invention est particulièrement sensible à la pression ce qui a pour effet d'améliorer efficacement la qualité de l'impression. Par ailleurs, la bague d'étanchéité de cette invention est très étanche au repos. Lors du fonctionnement de l'aiguille d'impression, la pièce de raccord se rompt, entraînant ainsi la séparation de la butée et de la bague d'étanchéité. Grâce à l'accouplement parfait de la pièce d'étanchéité et de l'aiguille d'impression, la pièce d'étanchéité est également très étanche lors de son utilisation.
