Abstract
An inkjet nozzle device includes: a nozzle chamber having a floor, a roof and perimeter sidewalls extending between the floor and the roof, wherein a nozzle aperture is defined in the roof; a heating element for generating gas bubbles in the nozzle chamber so as to eject ink through the nozzle aperture, wherein a centroid of the heating element is aligned with a centroid of the nozzle aperture; and a pair of chamber inlets defined in the floor of the nozzle chamber, the chamber inlets being symmetrically disposed about the centroid of the heating element. The inkjet nozzle device has a pair of orthogonal symmetry planes passing through the centroid of the nozzle aperture.
