Patent ID: 8205812

Claim:
A fluidic device that operates on a pressurized liquid flowing through said device at a specified flow rate to generate an oscillating spray of liquid droplets into a surrounding gaseous environment that has desired properties chosen from the group consisting of average spatial distribution, size, velocity, frequency and wavelength of said liquid droplets at a defined distance in front of said device, said device comprising: a plurality of fluidic oscillators, each having a channel that is part of a fluidic circuit for inducing oscillations in said pressurized liquid that flows through said oscillator so as to emit a liquid jet in the form of an oscillating spray of liquid droplets, a housing having an exterior surface that includes a front face and a rear face and an intermediate boundary surface that connects said faces, said front face having a center-point, a plurality of passages, each of which extends through said housing and intersects with said front and rear faces, each of said passages configured to allow for the insertion of one of said plurality of fluidic oscillators into each of said plurality of passages, wherein said intersections of said plurality of passages with said housing front face defining a plurality of outlets, and a geometrical arrangement of said outlets in said housing front face that is chosen so as to achieve said desired properties of said oscillating spray with said device operating at said specified flow rate.
