Abstract
An electrostatic spray coating device in which a coating material passes through a tube in a body and is electrostatically charged by electrodes as it exits the body. In the body is mounted a bar transformer for providing a high voltage to the electrodes. A magnetic conductor bar, such as a ferrite core, is also mounted in the body outside the bar transformer for conducting magnetic flux between its ends, thus providing a flux circuit within the body. If more than one conductor bar is used, the bars are spaced to facilitate heat discharge. A multiplying and rectifying circuit such as a Greinacher circuit may also be mounted in the body between the transformer and the electrodes, with its components distributed around the tube.
