20110085011 | INK SUPPLY SYSTEM HAVING DOWNSTREAM CONDUIT LOOP - An ink supply system for an inkjet printer. The ink supply system includes: an upstream ink conduit for connection with an ink inlet of a printhead; a pressure-regulating chamber having an outlet port connected to the upstream ink conduit, the chamber containing ink at a first level below the printhead, wherein a headspace above the first level of ink is open to atmosphere; and a downstream ink conduit for connection with an ink outlet of the printhead, the downstream ink conduit extending above the first level of ink and being open to atmosphere. The downstream ink conduit has a loop section passing below the first level of ink, such that, in a printing configuration, a second level of ink in the loop section is equal to the first level of ink in the chamber. | 04-14-2011 |
20120001989 | INKJET PRINTER WITH FLOAT VALVE PRESSURE REGULATOR - An inkjet printer includes: an ink reservoir; a printhead having an ink inlet and an ink outlet; an upstream ink conduit connected to the ink inlet; a downstream ink conduit connected to the ink outlet; and a pressure-regulating chamber. The pressure-regulating chamber includes: an inlet port connected to the ink reservoir via a supply conduit; an outlet port connected to the upstream ink conduit; a vent open to atmosphere; and a float valve for maintaining a set level of ink in the pressure-regulating chamber. The float valve includes: an arm pivotally mounted about a pivot; a float mounted at one end of said arm; and a valve head connected to the arm for sealing engagement with a valve seat at the inlet port. | 01-05-2012 |
