Noncircular inkjet nozzle

An inkjet nozzle (300) includes an aperture (302) with a noncircular opening substantially defined by a polynomial equation. A droplet generator (100) is also described which includes a firing chamber (110) fluidically coupled to a fluid reservoir (105), a heating resistor (120) and a nozzle (300)....

More Information
Summary:An inkjet nozzle (300) includes an aperture (302) with a noncircular opening substantially defined by a polynomial equation. A droplet generator (100) is also described which includes a firing chamber (110) fluidically coupled to a fluid reservoir (105), a heating resistor (120) and a nozzle (300). The nozzle (300) includes an aperture (302) forming a passage from the firing chamber (110) to the exterior of the droplet generator (100) through a top hat layer (400). The nozzle (300) is defined by a closed polynomial and has a mathematically smooth and mathematically continuous shape around aperture's perimeter wall (910), with two protrusions (310) extending into the center of the aperture (302).
