(FR) CARTOUCHE DE LIQUIDE
Abstract:
(EN) A liquid cartridge (30) includes: a cartridge casing (130) having a liquid storage chamber (32, 33); a first wall (136); a second wall (132); and an air communication passage (72). The first wall (136) is positioned upward of the liquid storage chamber (32, 33). The second wall (132) is positioned upward of the first wall (136). The air communication passage (72) has a first communication hole (46) and a communication opening (147). The air communication passage (72) includes: an air chamber (36) in communication with the liquid storage chamber (32, 33) through the first communication hole (46); a second communication hole (142) formed in the second wall (132); and a labyrinth path (143) positioned upward of the air chamber (36) and having one end in communication with the second communication hole (142) and another end in communication with the communication opening (147) opening to atmosphere.
(FR) La présente invention concerne une cartouche de liquide (30) qui comprend : un boîtier de cartouche (130) ayant une chambre de stockage de liquide (32, 33) ; une première paroi (136) ; une seconde paroi (132) ; un passage de communication d'air (72). La première paroi (136) est positionnée vers le haut de la chambre de stockage de liquide (32, 33). La seconde paroi (132) est positionnée vers le haut de la première paroi (136). Le passage de communication d'air (72) présente un premier trou de communication (46) et une ouverture de communication (147). Le passage de communication d'air (72) comprend : une chambre à air (36) en communication avec la chambre de stockage de liquide (32, 33) à travers le premier trou de communication (46) : un second trou de communication (142) formé dans la seconde paroi (132) ; un trajet de labyrinthe (143) positionné vers le haut de la chambre à air (36) et ayant une extrémité en communication avec le second trou de communication (142) et une autre extrémité en communication avec l'ouverture de communication (147) s'ouvrant vers l'atmosphère.
