Abstract
A spraying control system for an electrically conducting liquid ( ) emitted in the form of a pressurized jet ( ) through at least one nozzle ( ). The system contains apparatus for separating the liquid into drops, apparatus for electrically charging the drops and apparatus for applying an electrical deflection field to the charged drops. The system includes a first ( ) and a second ( ) monolithic element each with a continuous surface, laid out such that the continuous surfaces are facing each other and define a space ( ) between them in which the pressurized jet ( ) is emitted through the nozzle ( ). The elements ( ) include apparatus for continuously setting up potentials on the continuous surfaces to obtain the electrical charge of the drops and the electrical deflection field. The system also includes electronic control ( to ) for the potentials and apparatus for checking the intensity of electrical currents that can circulate on the continuous surfaces.
