Patent ID: 7651036

Claim:
A fluidic oscillator that operates on pressurized fluid flowing through said oscillator to generate an exhaust flow in the form of a spray of fluid droplets, said oscillator comprising: an inlet for said pressurized fluid, a set of three power nozzles that are fed by said pressurized fluid from said inlet, wherein each of said power nozzles configured to accelerate the movement of said pressurized fluid that flows through said power nozzles so as to form a herein defined free jet of fluid that flows from each said power nozzle, an interaction chamber attached to said nozzles and which receives said flow from said nozzles, wherein said chamber having an upstream and a downstream portion, said upstream portion having a pair of boundary edges and a longitudinal centerline that is approximately equally spaced between said edges, wherein one of said power nozzles being located proximate said longitudinal centerline of said interaction chamber, a throat from which said spray exhausts from said interaction chamber, and an island located in said interaction chamber, wherein said island being situated downstream of said power nozzle that is located proximate said longitudinal centerline of said interaction chamber.
