Abstract
A gas assisted spray nozzle assembly having a nozzle body in the form of a hollow tubular member, such as a single cylindrical pipe section, which defines a mixing zone and a downstream barrel extension zone. A liquid inlet and an impingement pin are supported by the tubular member in opposed relation to each other at the mixing zone, and a pressurized gas inlet is provided at an upstream end of the tubular member. An annular dispersion ring is fixedly supported within the tubular member downstream of the impingement pin for defining an annular ledge for directing a peripheral portion of pressurized gas stream and liquid atomized in the mixing zone radially inwardly for facilitating continued intermixing of the liquid and pressurized gas stream as they proceed through the barrel zone for discharge from the spray nozzle.
