ABSTRACT:
A fluidic oscillator comprises a housing having interior walls defining a cylindrical space therein, a fluidic oscillator is mounted in said cylindrical space and has an oscillating chamber having an upstream end and a downstream end. A power nozzle issues a jet of fluid into the oscillation chamber from the upstream end thereof, an outlet formed in the downstream end. A pair of control ports at opposing sides of the power nozzle are coupled to a pair of feedback entranceways in the downstream end of the oscillator chamber and at corresponding opposing sides of the outlet. The control passageways connect each feedback entranceway with the a control port on the opposing sides, respectively. Each control passageway is formed in part by the interior wall and the oscillator element.
