Nebulizers and method

Abstract From the Canadian patent

Pneumatic nebulizer and method for uniformly introducing 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 liquid particles of said liquid dispersed in said gas. The nebulizer comprises a mixing element for introducing the liquid in uniformly fine amounts into the gas flow. The mixing element which preferably is a replacable unitary element comprises two, superposed members which provide therebetween at least one shallow liquid orifice, at least a portion of the surfaces of said members either being in conforming surface contact with each other in the area between the …
