Abstract
A nozzle assembly for a material application device includes an expansion chamber for slowing down the velocity of powder fed to the nozzle from a dense phase pump. The nozzle assembly includes a nozzle insert that forms the expansion chamber and provides air assist function. The nozzle includes an integral deflector, and further includes a passageway for a charging electrode so that the electrical path is routed away from the powder path, while permitting the electrode tip to be centered in the powder spray pattern from the nozzle. The nozzle also includes air wash for the electrode. The nozzle outlet orifice has a cross-sectional area that is equal to or greater than the inlet cross-sectional area so that a slow moving dense phase powder cloud is produced by the nozzle.
