Abstract: An electrogasdynamically powered electrostatic spray gun is provided which discharges a liquid stream toward an object to be coated therewith. A first seeded air stream is selectively discharged from the spray gun to effect atomization of the fluid stream into a circular pattern and a second seeded air stream is selectively discharged from the spray gun to modify the shape of the atomized stream. The first and second seeded air streams are fed to their respective discharging zones through separate conduits which are supplied from a single feed. The shaping stream of seeded air can be reduced and the portion of the seeded air stream which would normally flow therethrough is redirected to bypass same whereby an undesirably high back pressure at the outlet of the electrogasdynamic generator will be avoided.

Abstract translation: 提供一种电动动力静电喷枪，其将液体流朝向要涂覆的物体排出。 第一种子气流从喷枪中选择性地排出，以使流体流雾化成圆形图案，并且第二种子气流从喷枪中选择性地排出以改变雾化流的形状。 第一和第二种子气流通过从单个进料供应的分开的管道供给到它们各自的排放区域。 可以减少接种空气的成形流，并且通常流过的种子气流的部分被重定向以旁路，从而避免电动发电机出口处的不期望的高背压。
