Claim 0:
1. A fluidic oscillator circuit for a nozzle assembly comprising: a geometry defined in a planar surface that includes: at least one inlet configured to receive a flow of fluid; an interaction region defined by a perimeter wall having: an outlet positioned centrally within a downstream portion of the perimeter wall; opposing first and a second power nozzles disposed between the downstream portion and an upstream portion of the perimeter wall, each of said first and second power nozzles configured to: i) produce respective jets of fluid received from the at least one inlet and ii) circulate the respective jets of fluid to form a plurality of vortices within the interaction region thereby dispensing an oscillating spray of fluid out of the outlet in a desired spray pattern; and an apex protrusion extends out from the upstream portion and partially into the interaction region toward the outlet; wherein the interaction region is positioned between the at least one inlet and the outlet; and wherein the upstream portion includes a dome shaped region interrupted along a middle portion by the apex protrusion.
