Abstract:
The invention relates generally to refillable ink cartridges for computer controlled ink jet printers and more specifically to apparatus for refilling collapsible ink bags which are maintained at sub-atmospheric pressure within such equipment. A mass of porous capillary material disposed in an ink supply passageway provides a capillary valve which prevents flow of ink when one side of the valve is unwetted.
