Patent number: 6685307Abstract: Apparatus for providing ink to an ink jet print head. The apparatus includes a back pressure regulator for receiving ink from an ink reservoir and for delivering ink to the print head. The regulator has a compliant wall that responds to atmospheric pressure on one side and to the pressure of the ink in the regulator on the another side. Within the regulator is a valve that regulates the pressure of the ink delivered to the print head and is actuated by the wall. Also within the regulator is a compression spring that simultaneously pre-loads the valve shut and urges the compliant wall against the atmospheric pressure. In an other aspect, an apparatus is provided with a print head having two arrays of nozzles and two back pressure regulators that independently deliver inks of different hues to separate arrays of nozzles on the print head.Type: GrantFiled: August 7, 2002Date of Patent: February 3, 2004Assignee: Hewlett-Packard Development Company L.P.Inventors: Daniel D. Dowell, Louis Barinaga, James P. Kearns
