ABSTRACT:
A valve device is incorporated within a printhead of an ink-jet pen for regulation of ink flow and pressure within the printhead. The valve device includes a valve member comprising a resiliently deformable flap positioned in an ink channel, adjacent a firing chamber. The flap is deflectable into and out of a position to regulate ink flow and pressure both to and from the ink firing chambers.
