A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction. After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet. The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet. A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vo...


A fluid oscillator comprising: nozzle means for forming and issuing a jet of fluid in response to application thereto of fluid under pressure; an oscillation chamber having a common inlet and outlet opening, said oscillation chamber being positioned to receive said jet of fluid from said nozzle means through said common opening, said oscillation chamber including: oscillation means for cyclically oscillating said jet back and forth across said chamber in a direction substantially transverse to the direction of flow in said jet; and flow directing means f...
