Appl. No.:

13/559122

Inventors:

Daniel A. Vidusek - Hampshire IL, US
Emily Pope - Glen Ellyn IL, US

Assignee:

SPRAYING SYSTEMS CO. - Wheaton IL

International Classification:

B05B 1/04

US Classification:

239429

Abstract:

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 pre-atomizing 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.

Abstract:

An internal mix air atomizing spray nozzle assembly comprising a nozzle body with a liquid discharge orifice defined by a relatively small diameter nose portion and an air cap having a central opening disposed in surrounding relation to the nose portion for defining an annular pressurized air passageway surrounding the liquid discharge orifice. To facilitate intermixing of liquid particles discharging from the air cap discharge orifices and for reducing negative pressures between the discharging flow streams, the air cap has an internal mixing chamber larger in diameter than the annular pressurized air discharge orifice and is formed with a plurality of circumferentially spaced discharge orifices oriented in skewed relation to a central axis of the nozzle. In the illustrated embodiment, the internal mixing chamber is defined by a cylindrical cavity within the air cap and a separate insert mounted in an upstream end of the air cap.
