Ink is filled in an ink cartridge having a housing communicating with ambient air through an air communicating hole, a porous member impregnating with ink, an ink supply port, and a valve device including a valve body always urged by a spring and a valve seat abutting against the valve body, and ink is filled in the housing of the ink cartridge through the ink supply port.
L'invention concerne un dispositif de remplissage d'encre dans une cartouche. Lorsqu'un orifice d'alimentation (3) en encre est relié à un tube de remplissage (21), un disque d'obturateur (11) est levé par ledit tube (21) afin d'ouvrir une voie d'écoulement de l'encre. L'encre est ainsi transportée à travers l'orifice d'alimentation (3) par une pression négative provenant d'un orifice en communication avec l'atmosphère (1a), puis absorbée dans un corps poreux, l'encre pouvant ainsi remplir, à débit élevé, la cartouche pourvue du corps poreux servant à stocker l'encre.
