Abstract

A spray nozzle comprises a liquid passage, spray air passages adapted to create a divergent jet of sprayed liquid and shaping air passages for shaping this jet. The shaping air passages include first passages having axes coplanar with the liquid passage. They converge to form a divergent flattened jet coplanar with the liquid passage and having a median plane perpendicular to the plane containing the axes of the first passages and the liquid passage. The shaping air passages also include second passages having axes disposed symmetrically to each side of the aforementioned plane and directed towards the aforementioned median plane.
