    • 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.
    • 公开了一种包括用于控制喷嘴的阀部分的矩阵阵列喷头。 喷头由一系列交替堆叠的板形成,该板具有形成在交替板中的通道,用于供应加压气态推进剂或由喷头施加的组合物。 适用于喷头喷涂的组合物包括涂料粉末,液体涂料,保形涂料,助熔剂,水和其它材料和流体,当与高压气流组合时可能被雾化。 组合物和气流的流动可以通过具有记忆金属阀元件的记忆金属阀控制在阀部分中,该记忆金属阀响应于由逻辑控制控制的电流的施加而移动。 阀的计算机逻辑控制提供了具有计算机可寻址的微小喷嘴阵列的喷头。
