Abstract

Liquid atomizer has a tubular body with vanes inclined to the axis of the body to form a rotation unit in the outflow end of the body. A first duct ends in a first nozzle, to inject liquid into the turbulent air stream behind the rotation unit, and a second duct ends in a second nozzle which has angularly offset nozzle openings and is arranged about the first nozzle. Preferably elements in the first duct impart a rotation to the liquid leaving the first nozzle, which has a single opening coaxial with the tubular body. The design is simple and efficient.
