摘要： An electrostatic spraying apparatus for spraying liquid has a spraying edge 8 provided with teeth 12. No parts of the apparatus provide a low potential influence near the spraying edge, keeping leakage losses to a minimum. At the voltage provided by a high voltage supply, the field strength at the tips of the teeth 12, is sufficient to form one ligament of liquid per tooth. The ligaments break up into droplets which have a size largely independent of fluctuations in field strength caused by varying the distance from the target to be sprayed.
