摘要： The invention provides a flow feature structure for an ink jet printer. The structure includes a polymeric nozzle plate having a nozzle plate thickness, the nozzle plate containing a plurality of ink chambers, each ink chamber containing a nozzle hole in fluid communication therewith, a plurality of ink channels each having a channel width and an ink channel inlet for providing ink flow from an ink supply region to one each of the ink chambers and an air bubble interrupter device having a width dimension perpendicular to a flow axis through the ink channel. The width dimension of the air bubble interrupter is from about 0.5 to about 1.2 times the ink channel width and the interrupter device is disposed adjacent each of the ink channels and spaced from the ink channel inlet a distance of from about 0.5 to about 1.2 times the ink channel width. Such a structure provides improvement in ink flow by reducing the size of air bubbles which may form or accumulate in the flow areas of the nozzle plate so that the air bubbles do not block or inhibit the flow of ink to the ink chambers or affect the ejection of ink from the nozzle holes.

摘要： A print head and regulator assembly for a printer including: (a) a print head; (b) an ink source; and, (c) a regulator for regulating the flow of ink between the ink source and the print head, the regulator including: (i) a pressurized chamber having an ink inlet in fluid communication with the ink source, an ink outlet in fluid communication with the print head, an opening extending through a chamber wall, and a flexible film covering the opening, the flexible film having an inner surface facing an interior of the pressurized chamber and an outer surface in contact with the ink in the ink source; and, (ii) a lever including a flexible arm positioned in proximity to the inner surface of the flexible film and an opposing arm operatively coupled to a seal that closes the ink inlet when the lever is in a first position and opens the ink inlet when the lever is pivoted to a second position, the lever being biased to the first position, where a higher pressure differential across the flexible film brings about a higher force acting upon the flexible arm to overcome the bias and pivot the lever to the second position opening the ink inlet, and, where a lower pressure differential across the flexible film brings about a lesser force acting upon the flexible arm resulting in the lever succumbing to the bias and repositioning the seal at the first position, closing the ink inlet.
