Abstract
A spray nozzle assembly comprising a nozzle body and a separate nozzle body insert adapted for removable snap action engagement with the body. The nozzle body insert defines a liquid flow passage that includes an inlet section for communicating with a liquid inlet, a metering orifice for accelerating the liquid flow stream, and a downstream expansion section. The body insert further includes a venturi passage communicating with the expansion section for drawing ambient air into the liquid flow stream for stabilizing the liquid prior to discharge from the nozzle. In the illustrated embodiment, the expansion chamber communicates with a transverse passage of the nozzle body, which in turn communicates with a laterally oriented discharge orifice.
