Abstract
An apparatus for electrostatic atomization of liquids, particularly fuel, has a nozzle, which has a nozzle body of electrically conductive material, connected to ground potential, with a nozzle opening for the emergence of a volume of liquid under pressure and has an electrode in the nozzle body, coaxially opposite the nozzle opening, which electrode is at a high-voltage potential. To avoid a corona discharge of the electrically charged liquid volume emerging from the nozzle opening, which would limit the magnitude of the possible electric charging of the liquid volume in the nozzle and thus the degree of atomization, nonelectrical means are provided toward the nozzle opening for atomizing the liquid volume as it emerges from the nozzle, and these means are embodied such that the mechanical breakaway forces they produce in the liquid volume are effective sooner than the forces of electrostatic repulsion prevailing between the liquid droplets. One example of such means is swirl conduits that discharge immediately upstream of the nozzle opening.
