    • 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。

    • A fluid spray nozzle that mixes a pressurized gaseous propellant and paint composition prior to being applied to a workpiece. The nozzle includes an upstream section for receiving the pressurized gaseous propellant. The nozzle directs the gaseous propellant and the fluid composition into a recirculation cavity. The gaseous propellant and fluid composition are received in a downstream section after mixing in the recirculation cavity. The recirculation cavity has lobes on opposite sides of a flow path defined in a region in the recirculation cavity between an inlet opening and the recirculation cavity. The recirculation cavity is formed by silicon micromachining the upstream section, fluid injection section, recirculation cavity and downstream section. The gaseous propellant may be accelerated to supersonic speeds prior to entering the recirculation cavity. The gaseous propellant and fluid composition are decelerated to subsonic speeds prior to exiting the downstream section, thereby resulting in the formation of a shock wave at the transition from supersonic to subsonic speeds which causes further atomization of the fluid composition.
    • 流体喷嘴,其在施加到工件之前将加压的气体推进剂和涂料组合物混合。 喷嘴包括用于接收加压气体推进剂的上游部分。 喷嘴将气体推进剂和流体组合物引导到再循环腔中。 气体推进剂和流体组合物在再循环空腔中混合后被接收在下游部分中。 再循环腔在限定在再循环空腔中的入口开口和再循环腔之间的区域中的流路的相对侧上具有凸角。 再循环腔通过硅微加工上游部分,流体注入部分,再循环腔和下游部分形成。 在进入再循环空腔之前,气体推进剂可以被加速到超音速。 气体推进剂和流体组合物在离开下游段之前减速至亚音速,从而导致在从超音速到亚音速转变的过程中形成冲击波,这导致流体组合物的进一步雾化。
