Abstract: This electrostatic sprayer of coating products with external load, comprises a bowl rotatable about an axis, a turbine for rotating the bowl around this axis, and a plurality of first electrodes distributed around the axis and each capable of emitting, when the sprayer is operating and is at least partly in the direction on an object to be coated, a first ion flux from a first point. The first points are arranged in a first circle centered on and perpendicular to the axis. The sprayer comprises second electrodes each capable of emitting, when the sprayer is operating and mainly or exclusively in the direction of an edge of the bowl, a second ion flux, of the same sign as the first ion flux, from second points arranged in a second circle centered on and perpendicular to the axis, and having a different radius than the first circle.

Abstract: An electrostatic spray device for spraying a liquid coating product, including a rotating bowl and a device for driving the bowl around a rotational axis, the bowl defining a concave surface for distributing the coating product and an edge which limits an area for the spraying the coating product. The spray device includes an electrode that charges by ionization of drops of the coating product. The electrode is arranged, in relation to the edge and along the rotational axis, opposite the spray area, between the edge and the device for driving the bowl. A second electrode mounted on a stationary body allows the creation of an electrostatic field for transporting drops. A third electrode, which is also mounted on a stationary body, is brought to an intermediate potential between those of the first and second electrodes during the operation of the spray device.
