Abstract:
1. A pressurized air atomized liquid spray device comprising: an atomizing unit having a liquid inlet for communicating pressurized liquid from a pressurized liquid supply to a central liquid passage having a discharge orifice through which the liquid is forcefully directed, an impingement element defining impingement element defining impingement surface disposed in aligned relation to said liquid discharge orifice against which a liquid steam discharging from the liquid discharge orifice will impinge and shatter into liquid particles that are dispersed radially outwardly of the impingement surface, said atomizing unit having an atomizing air inlet for communicating pressurized air from a pressurized air source into communication with at least one air passageway oriented for directing the pressurized air stream for interaction with liquid impinging from said impingement surface for causing interaction and further liquid breakdown into atomized liquid particles for direction into an expansion chamber entirely downstream of said impingement element, said expansion chamber having an uninterrupted cross section greater in diameter than the diameter of the impingement surface, said atomizing unit having a plurality of atomized liquid direction passages communicating with said downstream expansion chamber disposed in eccentric relation to said central liquid flow passage, a plurality of tubes each communicating with a respective one of said atomized liquid direction passages for receiving and transmitting atomized liquid, and a spray nozzle coupled to a downstream end of each tube for discharging an atomized liquid spray at the respective location of the spray nozzle.
