PRESSURIZED AIR ASSISTED SPRAY NOZZLE ASSEMBLY

摘要

A pressurized air-assisted liquid spray nozzle assembly having an air direction member that defines a central longitudinal airflow passage having an upstream end for coupling to a pressurized air supply and a plurality of cross-passages for directing a plurality of pressurized air streams radially outwardly, a liquid direction guide disposed in surrounding relation to the air direction member having a plurality of circumferentially spaced liquid passages extending transversely across the cross-passages for intersecting pressurized liquid and air streams and preatomizing the liquid, a downstream expansion chamber for receiving pre-atomized liquid, and discharge orifice communicating centrally with said expansion chamber for emitting a predetermined atomized liquid spray pattern.
