Ink jet nozzle assembly including a fluidic seal
First Claim
1. An ink jet nozzle assembly including a nozzle chamber containing ink to be ejected, said chamber including a fixed portion and a movable portion configured for relative movement in an ejection phase and alternate relative movement in a refill phase, wherein a fluidic seal comprising a meniscus formed by said ink extends between the movable portion and the fixed portion.

Abstract
An ink jet print head includes a nozzle chamber for storage of ink to be ejected from an ink ejection nozzle formed in one wall of the nozzle chamber; and a movable paddle actuator mechanism formed in a first wall of the nozzle chamber, one end of the paddle actuator traversing along a second wall of the nozzle chamber, the second wall being substantially perpendicular to the first wall; the one end further including a flange having a surface abutting the second wall, the movable paddle actuator mechanism being operable to cause the ejection of ink from the ink ejection nozzle with the flange moving substantially tangentially to the second wall.

5. An ink jet nozzle assembly including:
-
a nozzle chamber having an inlet in fluid communication with an ink reservoir and a nozzle through which ink from said chamber can be ejected;
the chamber including a fixed portion and a movable portion configured for relative movement in an ejection phase and alternate relative movement in a refill phase;
the movable portion being formed in a first wall of said nozzle chamber and having one end traversing adjacent a second wall of said nozzle chamber, said second wall being substantially perpendicular to said first wall; and
the inlet being positioned and dimensioned relative to the nozzle such that ink is ejected preferentially from the chamber through the nozzle in droplet form during the ejection phase, and ink is alternately drawn preferentially into the chamber from the reservoir through the inlet during the refill phase. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
