Abstract

Cartouche, dans laquelle une quantité réduite d'encre reste dans la cartouche quand elle est usagée, un utilisateur pouvant la remplir à nouveau d'encre, ayant une structure simple et qui peut être produite d'une manière peu coûteuse. La cartouche comprend un conteneur d'encre (10) avec une structure isolée qui comprend à l'intérieur de celle-ci un espace destiné à recevoir de l'encre, une ouverture d'amenée d'encre (14) qui est fournie dans la face inférieure du conteneur et qui fournit de l'encre à une tête d'enregistrement d'un support quand elle est soumise à une pression négative de la tête d'enregistrement, un chemin de guidage d'encre (17) dont la partie s'étendant jusqu'à sa section de départ, qui est ouverte à proximité de la partie inférieure du conteneur, est étendue vers le haut et retournée ensuite vers le bas, dont sa section d'extrémité est en communication avec l'ouverture d'amenée d'encre, et qui guide l'encre en étant soumis à une pression négative de la tête d'enregistrement, et une chambre de soupape de commande d'encre (18) qui est fournie à la partie de retour supérieure. Dans la chambre de soupape de commande d'encre (18), quand une soupape de commande est ouverte en étant soumise à une pression négative de la tête d'enregistrement, la soupape permet l'écoulement de l'encre dans le chemin de guidage d'encre vers l'ouverture d'amenée d'encre, et, quand soupape de commande n'est pas soumise à la pression négative, la soupape empêche le refoulement de l'encre dans le chemin de guidage d'encre.
