ABSTRACT:
A dual pattern nozzle comprises a fluid oscillator of the type which utilizes an obstacle or island in the path of liquid flow to produce a vortex street downstream of the island. A flow splitter is disposed downstream of and sufficiently close to the island to prevent the flow around the island from re-combining before reaching the flow divider, whereupon liquid vortices are alternately issued from each side of the divider. The spinning liquid breaks up into two patterns of droplets, the patterns being directed at respective spaced areas.
