Abstract
An ink jet nozzle assembly includes a nozzle chamber having an inlet in fluid communication with an ink reservoir and a nozzle through which ink from the chamber can be ejected. The chamber includes a fixed portion and a movable portion configured for relative movement in an ejection phase and alternate relative movement in a refill phase. An expanding, flexible arm and a rigid arm are each connected to the movable portion and cooperate to effect periodically the relative movement. The inlet is 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.
