Abstract:
A spray nozzle system for skin treatments includes separate air outlets moving over the skin surface to deliver one or more streams of supplemental air for the purpose of warming or drying the skin surface to improve efficacy and comfort of the spraying experience. The drying air from the auxiliary ports may be applied while spray is emitted from the nozzle to increase the spray cloud temperature, or may be applied before or after the spray application, with the spray turned off, to warm or dry the skin. A heating source is provided to warm the air directed through one or more supplemental air ports In the case of air-atomizing nozzles, the supplemental air is delivered through low pressure ports separately from the air emitted through the nozzle's atomizing and pattern shaping orifices to minimize the expansion cooling effect inherent with the spray nozzle ports.

Abstract:
A light-weight spray gun with an improved air control flow distribution to the spray gun nozzle is described, comprising a die-cast aluminium body (1) and a handle (2) of hard plastics material, the body having a spray head (3) and a nozzle (4) both of plastics material with weirs (5) providing an efficient baffling of the flow of air giving an even distribution of air to both the central atomising air to nozzle (4) and the flow of spreader air to horns (6) of the aircap. The weirs (5) are created by the profile of the spray head (3) and the external profile of nozzle (4). The aluminium body (1) is permanently joined to the outer profile of the plastics head (3) by a metal ring (10) to provide an efficient mechanical joint and seal between the parts. The invention includes an improved air distribution control valve.
Abstract:
An external mix air assisted spray nozzle assembly having a nozzle body with pressurized liquid and air passages, an air cap having a central opening in coaxial relation to a liquid discharge orifice of the nozzle body for discharging an annular air stream in surrounding relation to liquid discharging from the discharge orifice, and the air cap has a pair of opposed thin walled cylindrical members projecting in opposed relation to each other for directing pressurized air to atomize and shape the discharging liquid spray pattern, while minimizing undesirable build up of solids on the terminal ends of the projecting cylindrical members.
Abstract:
A spraygun (1) operable by low pressure high volume air is described comprising a body (4) and a nozzle (21) having a fluid orifice for discharging a fluid jet and an air cap (24) attached to the front of the body by a retaining ring (35), the air cap (24) defining an annular orifice about the fluid nozzle (21) for discharging atomised air, wherein the air inlet for supplying air to the spraygun (1) has a first restricting means (3) to reduce the pressure of air to the spraygun and a second restricting valve means (11) to control the flow of air to the air cap (24).
Abstract:
The invention relates to a spray gun apparatus (10) for spraying a fine film coating of liquid, such as paint, lacquer or bond, onto a surface. The spray gun comprises a main body (12) having a fluid throughbore (22), a gas throughbore (16), and a main trigger lever (80) for allowing a user to spray fluid from the gun. A fluid flow adjustment mechanism (52, 58, 74) facilitates adjustment of the quantity of fluid sprayed from the gun for a given displacement of the main trigger lever (80). An engagement surface (86) is provided on the trigger lever and adapted to engage with a corresponding engagement surface (90) of the fluid flow adjustment mechanism. Pivoting movement of the main trigger lever (80) results in translational movement of at least a portion of the fluid flow adjustment mechanism to thereby selectively spray fluid from the gun upon displacement of the main trigger lever.

Abstract:
A spray nozzle system includes separate air outlets to deliver one or more streams of supplemental warming or drying air. The air may be applied while spray is emitted from the nozzle to increase the spray cloud temperature, or may be applied for warming or drying before or after the spray application, with the spray turned off. In the case of air-atomizing nozzles, the air is delivered through low pressure ports separately from the atomizing or pattern shaping air to minimize the expansion cooling effect. In another implementation, the air is redirected from the nozzle using a control valve which proportions the amount of airflow directed for atomization, pattern shaping and drying.
