Abstract: A drive gas flowing into a nozzle is allowed to suck with it, by ejector action, an extraneous gaseous medium such as ambient air, the sucked-up medium entraining from a container the liquid to be atomized. The liquid is atomized as the ambient air is mixed with the drive gas flow. An apparatus for carrying out this method includes a nozzle for supplying the drive gas, the container for supplying liquid which is to be atomized, and an inlet between the container and the nozzle for supplying ambient air, or another gaseous medium, to be sucked along with and mixed with the drive gas. A portion of the container in communication with the inlet provides an outlet through which the liquid is entrained by the inrushing ambient air as it is sucked into the drive gas flow path. The flow of ambient air past the container opening to the nozzle is adjustable.
