CA 2419785

An improved ink cartridge dispensing valve system (10) is provided. The valve system (10) works on the same principle as a ball valve to automatically dispense ink when subjected to pressure. The valve system (10) includes an attachment post (18) and an attachable nozzle (12). The attachment post (18) is an integral part of the dispensing end of the ink cartridge and is recessed so that the cartridge can be easily shipped without damaging the attachment post (18). The attachable nozzle (12) fits over the attachment post (18) and opens or closes depending on whether pressure is placed on it by the ink in the cartridge.

L'invention concerne un système (10) amélioré de soupape de distribution de cartouche d'encre. Le système (10) de soupape fonctionne sur le même principe qu'une soupape à bille de façon à distribuer automatiquement l'encre lorsqu'il est soumis à une pression. Le système (10) de soupape comprend une tige (18) de fixation et une buse (12) associée. La tige (18) de fixation fait partie intégrante de l'extrémité de distribution de la cartouche d'encre, et comporte un évidement qui facilite le transport de la cartouche sans endommager la tige (18) de fixation. La buse (12) associée s'installe sur la tige (18) de fixation et s'ouvre ou se ferme en fonction de la pression appliquée sur celle-ci par l'encre de la cartouche.
