The invention concerns a control system for spraying an electrically conductive liquid (3) emitted in the form of a pressure jet (4) by means of a nozzle (2), comprising means for fractionating the liquid jet into droplets, means for electrically charging said droplets and means for applying a deflecting electric field to the charged droplets. The system comprises: a first (8) and a second (6) monolithic element each having a continuous surface, arranged such that the continuous surfaces are facing each other and define between them a space (5) wherein the pressure jet (4) is emitted by said nozzle (2), said elements (6, 8) including means for constantly providing voltages to said continuous surfaces to obtain said current load of the droplets and said deflecting electric field; electronic means (31 to 36) controlling said voltages and controlling the intensity of the electric currents circulating on said continuous surfaces.
L'invention concerne un système de commande de projection d'un liquide électriquement conducteur (3) et émis sous forme d'un jet sous pression (4) par au moins une buse (2), comprenant des moyens pour fractionner le jet de liquide en gouttes, des moyens pour charger électriquement lesdites gouttes et des moyens pour appliquer un champ électrique de déflexion auxdites gouttes chargées. Ce système comprend: un premier (8) et un deuxième (6) élément monolithique présentant chacun une surface continue, disposés de façon que les surfaces continues soient en vis-à-vis et définissent entre elles un espace (5) dans lequel le jet sous pression (4) est émis par ladite buse (2), lesdits éléments (6, 8) incluant des moyens permettant d'établir continûment des potentiels sur lesdites surfaces continues pour obtenir ladite charge électrique des gouttes et ledit champ électrique de déflexion, des moyens électroniques (31 à 36) de commande desdits potentiels et de contrôle de l'intensité des courants électriques pouvant circuler sur lesdites surfaces continues.
