摘要:
An ink-jet bottle and valve system which delivers ink-jet ink to an ink-jet printer apparatus having an ink reservoir. The system has five, main components: (1) a bottle, (2) a housing, (3) a valve, (4), a cover, and (5) a vent tube. Coupled to the ink reservoir, the housing has a nozzle which extends into the ink reservoir and defines a channel through which ink may flow from the bottle to the ink reservoir. The top surface of the housing has a cutout defining a pair of valve rotation stops. The housing also has a bottom surface which includes a lower vent and a lower ink passage each opening to the channel of the nozzle. The valve fits snugly and rotatably within the housing. The internal surface of the valve is threaded to couple the valve to the threaded neck of the bottle. The bottom surface of the valve has an upper vent and an upper ink passage. Finally, a top surface of the valve has a projecting tab. The tab rests in the cutout of the housing and cooperates with the pair of valve rotation stops to limit axial rotation of the valve within the housing between (i) a first position where the tab abuts one valve rotation stop and in which the upper vent and the upper ink passage of the valve align with the lower vent and the lower ink passage, respectively, of the housing, and (ii) a second position where the tab abuts the other valve rotation stop and in which the upper vent and the upper ink passage of the valve are out of alignment with the lower vent and the lower ink passage, respectively, of the housing. The cover engages a flange on the housing and captivates the valve within the housing. Finally, the vent tube allows air, required to equalize the pressure in the bottle, to pass directly to the area at the top of the bottle above the ink and assure even ink flow.
