Abstract: Electrostatic spraying apparatus employs a concealed electrode at a low potential (relative to that used in conventional apparatus) to form an induced charge on a thin layer of liquid. Subsequent mechanical atomization of the charged layer produces a spray of charged droplets. The thin layer is produced by centrifugally spreading an inlet flow and atomization may also be achieved by rotation. An air flow is arranged to sweep the charged droplets out of the field of the electrode and a baffle, in which the electrode is embedded, is formed to control the direction of emergence of the spray from the nozzle.

Abstract translation: 静电喷涂装置采用低电位（相对于常规装置中使用的）的隐藏电极，在薄层的液体上形成感应电荷。 随后的带电层的机械雾化产生带电液滴的喷雾。 通过离心地扩散入口流产生薄层，并且雾化也可以通过旋转实现。 空气流被布置成将带电的液滴吹扫出电极的场，并且形成电极嵌入的挡板，以控制喷嘴从喷嘴出来的方向。
