ABSTRACT:
Apparatus for producing finely divided liquid particles which includes two chambers having means for conveying liquid from one chamber to the other and back again to the first chamber in response to a means for producing a pressure differential between the chambers. A hollow apertured plenum chamber having a smooth outer surface is positioned so that the liquid impinges on its exterior surface as it traverses its flow path. Gas is supplied under pressure to the interior of the plenum and ruptures the thin film of liquid at the aperture to produce the finely divided liquid particles.
