Abstract
An air spray gun comprising a nozzle with a frustoconically profiled tip, a cylindrical through bore, a V-shaped groove running across said through bore to form an oblong opening for ejecting paint under a pressure of 1 to 6Ckgf/cm.sup.2 and atomizing the ejected paint by compressed air having a pressure of 0.5 to 2 kgf/cm.sup.2, wherein an air cap is arranged to form an annular air outlet between the outer periphery of the nozzle tip and a central air outlet of the air cap and the nozzle tip is located within a front central through bore of the air cap. The invention preferably has at least a pair of auxiliary air outlets arranged in juxtaposition across the axis of the oblong opening to make the air jet streams from the air outlets cross and crash against the paint stream and at least a pair of angular air outlets to make the air jet streams from the angular air outlets cross and crash against the paint stream downstream of the first crossing and perpendicular to the first air jet streams to that the paint will be atomized under relatively low air pressure to prevent paint dissipation and consequently enhance the efficiency of painting.
