ABSTRACT:
There is disclosed a fluidic oscillator in which a stream of fluid is directed against a barrier member in an oscillation chamber. The barrier member serves as one wall of the oscillation chamber and in conjunction with other shaped wall surfaces of the oscillation chamber creates a pair of alternately pulsating control vortices for causing the fluid in the power stream to pass alternately to a pair of outlet passages. The vortices alternate both in strength and in a phase opposition to control flow of the jet stream in alternate fashion through the outlet passages. In a preferred embodiment of the invention, the pair of outlet passages are on opposite sides of the barrier member and converge to a common outlet to thereby provide a fan spray as the outlet passages alternate in the passage of the stream of fluid therethrough to the common outlet.
