INK PRESSURE REGULATOR WITH REGULATOR CHANNEL POSITIONED IN CHAMBER ROOF |
摘要 |
An ink pressure regulator for regulating a hydrostatic pressure of ink supplied to an inkjet printhead. The regulator includes an ink chamber having an ink outlet for fluid communication with the printhead via an ink line. A roof of the ink chamber includes: an air inlet; a regulator channel having a first end communicating with the air inlet and a second end communicating with a headspace of the chamber, the second end defining a bubble outlet; and a wetting system for maintaining liquid in the regulator channel, thereby ensuring that air entering the headspace first passes through the liquid. The regulator channel is dimensioned to control a Laplace pressure of air bubbles drawn from the bubble outlet as result of supplying ink to the printhead.
