Abstract: A fluid spraying or nozzle system adapted for use with cold fluids, viscous fluids or fluids under light pressure includes a fluidic oscillator having a power nozzle and an oscillation chamber coupled to the power nozzle for issuing a jet of fluid into the oscillation chamber and an outlet aperture spraying a jet of fluid into ambient space. The oscillator's walls define an oscillation inducing interaction region causing the jet of fluid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber. The oscillation inducing interaction region defines an outlet throat width which is adapted to work with the power nozzle's width and an a bell-shaped feed that spreads the fluid jet as it leaves the power nozzle, so that the interaction region and feedback channels are quickly filled with fluid at a low pressure and the fluidic oscillator is activated to generate a desired fan pattern of fluid spray.
