Abstract
A spray nozzle assembly for producing an oscillating spray discharge is provided. The spray nozzle assembly includes a nozzle body with a liquid inlet passage that converges via an inwardly converging conical section that defines a liquid inlet orifice. An expansion chamber communicates in a downstream direction with the liquid inlet orifice. An exit orifice communicates in the downstream direction with the expansion chamber. A pair of longitudinal veins and a pair of outwardly disposed feedback passages are provided in the expansion chamber. Each vein defines a respective downstream orifice to a respective one of the feedback passages adjacent the exit orifice and an upstream orifice to the respective one of the feedback passages adjacent the inlet orifice.
