Abstract
For those spray applications that use a fluidic oscillator of the type that generates a spray by having a pressurized liquid flow through the oscillator and exhaust into a surrounding environment, and where such an oscillator has a boundary surface which has fabricated into it a channel in the form of what is referred to herein as fluidic circuit, an improved enclosure for this oscillator includes: a body having an interior and an exterior surface, wherein a portion of this interior surface is configured to attach to the oscillator boundary surface so as to form with the oscillator's channel an enclosed pathway through which the to-be-sprayed liquid may flow, and wherein a segment of this interior surface is configured so as to yield specified properties of the resulting spray.
