ABSTRACT:
An improved constant-output atomizer (30) includes a body (38) which has a generally frustoconical expansion nozzle (36) for producing an air jet when a supply of pressurized air is connected to the nozzle upstream of the throat of the nozzle. A liquid feed line (40) supplies liquid to be atomized by the air jet, and the body includes a groove (42) which opens into the diffuser section of the nozzle downstream of the throat for conducting liquid from the feed line to the nozzle. The groove extends in a direction perpendicular to the axis of the nozzle, and radially with respect thereto; and it has a depth approximately equal to half the axial length of the nozzle. Liquid, conducted by capillary action in the groove to the nozzle, is atomized into a fine mist by the air jet in the nozzle; and the groove eliminates fluctuations in spray order.
