ABSTRACT:
A matrix array spray head including a valve section for controlling nozzles is disclosed. The spray head is formed by a series of alternately stacked plates having channels formed in alternate plates for supplying either pressurized gaseous propellant or a composition to be applied by the spray head. Compositions appropriate for spraying with the spray head include paint powder, liquid paint, conformal coatings, flux, water and other materials and fluids which may be atomized when combined with a high pressure gaseous stream. Flow of the composition and gaseous stream may be controlled in the valve section by means of memory metal valves having memory metal valve elements that move in response to the application of electrical current controlled by a logic control. The computer logic control of the valves provides a spray head having a computer-addressable array of tiny spray nozzles.
