Abstract
Nozzle assemblies adapted to produce an oscillatory spray pattern. A rotor member having at least one lobe engaged with one or more cavities of a stator surface for defining an oscillatory movement of the rotor member in response to a motive fluid along the rotor member and stator surface. The nozzle assembly directing the motive fluid along one or more tapered surfaces, such as complementary tapered surfaces of the rotor and stator surface. The rotor member is operatively coupled with the spray member for oscillatory movement therewith. The spray member adapted to receive the motive fluid and emit the fluid as a spray from the nozzle assembly. The spray having an oscillatory pattern that matches the oscillatory movement of the rotor.
