Abstract
Atomizing spray nozzle for mixing and atomizing various liquid and gas combinations includes a central liquid conduit, an annular gas passage disposed concentrically about the liquid conduit, a helical spray member and a spray head. The spray member includes a bore disposed in axial alignment with the liquid conduit and is of helical configuration which, in cross-section, tapers inwardly toward the distal end thereof. The spray head is of generally tubular configuration and encloses the helical member, except for at least one outlet orifice through its outer end wall. The spray head provides a chamber for the mixing of the gas and liquid and for the discharge of the resulting mixture through the orifice of the head to form an atomized spray.
