Abstract of the Disclosure Pneumatic nebulizer and method for uniformly supplying variable small amounts of flowable liquid into a gas flow to form a stable dispersion having the appearance of a natural fog and consisting essentially of microscopic particles of said liquid dispersed in said gas. The nebulizer comprises a means for controlling the rate of flow of said liquid, a mix- ing element having one or more narrow liquid orifices through which the liquid is supplied in uniformly fine amounts, a filming surface onto which the liquid is drawn and stretched and a gas orifice which introduces the stretched liquid film into the gas flow. The mixing element which may be a replace- able unitary element, comprises a filming surface having an affinity for the liquid being dispersed in the gas flow, at least one liquid passage adapted to receive a regulated supply of said liquid and having a very small exit orifice on said filming sur- face, and a gas orifice communicating with an edge of said film- ing surface and spaced from said very small liquid orifice and adapted to receive liquid from said filming surface in the form of the thinnest continuous filament or film of said liquid which can be drawn across said surface by the cohesive force between the liquid being dispersed at said gas orifice and the liquid on said surface. Each very small liquid orifice receives a metered continuous supply of the liquid forced or drawn from a liquid supply chamber, either by pressure or by vacuum, to supply uni- form predetermined amounts of liquid onto said filming surface to permit said liquid to be drawn into a thin filament or film as it is pulled to the gas orifice for dispersion into the gas flow.
