Abstract
A spray nozzle which employs compressed air for atomizing the liquid to be sprayed and for projecting these droplets into the desired spray pattern. The nozzle includes a tubular member and a liquid supply conduit and nozzle head mounted within the tubular member. There is an annular passage through the nozzle with a converging portion and a portion diverging from the converging portion. Liquid and gas are supplied to the converging portion. The compressed gas is supplied in a manner to achieve swirling of both the gas and liquid within the converging portion. The compressed gas discharges the atomized liquid in a hollow conical spray pattern.
