Patent ID: 8172162

Claim:
An improved fluidic oscillator that operates on a pressurized liquid flowing through said oscillator to generate an oscillating spray of liquid droplets into a surrounding gaseous environment, said oscillator of the type having a centerline, an interaction chamber and a means for inducing oscillations in said liquid flowing through said chamber, said chamber having sidewalls that extend downstream and converge towards said oscillator centerline so as to form an outlet for said oscillator, wherein the improvement comprises: a splitter having a generally flat surface with a first and second edge, said surface facing generally in the upstream direction towards said interaction chamber, wherein said oscillator outlet having a first and a second edge, each of which are laterally spaced away from said oscillator centerline and serve to define an oscillator outlet plane that is generally perpendicular to said oscillator centerline, said first splitter edge situated a first specified distance downstream of said oscillator outlet plane and said second splitter edge situated a second specified distance downstream of said oscillator outlet plane, said first splitter edge cooperating with said outlet first edge to cause a portion of the liquid that flows through said outlet to split into a first component spray that flows between said first splitter and outlet edges, said first component spray having a centerline that has an imposed, first splitter angle relative to said oscillator centerline, and said second splitter edge cooperating with said outlet second edge to cause a portion of the liquid that flows through said outlet to split into a second component spray that flows between said second splitter and outlet edges, said second component spray having a centerline that has an imposed, second splitter angle relative to said oscillator centerline.
