<p>A stacked drop generator apparatus (20) for ink jet printing includes a stackable housing (22) of electrically nonconductive material having a cavity (24) containing fluid. A pressure wave is produced in the fluid by a device (26) which is deformed in response to electrical pulses. Each cavity (24) is flooded with fluid and has a nozzle (40) integral with the housing. The nozzle has an intake end (41) in the fluid cavity, an exit port (42) through which fluid is expelled from the housing. The cavity of the housing adjacent the nozzle has a tapered shape to concentrate the effect of the pressure wave on the fluid.</p> |
