Abstract
A liquid-atomizing spray gun having an improved nozzle construction for spraying liquids under predetermined hydraulic pressures, and with the assistance of carbon dioxide gases, wherein the nozzle includes a forwardly-projecting shield having ports directed toward the atomized spray pattern emanating from a spray tip. The nozzle also includes ports for ejecting CO.sub.2 gas for assisting in the atomization process, the overall design providing CO.sub.2 -assisted hydraulic spraying and preventing air entrainment into the atomized particles in the region proximate the spray nozzle.
