Abstract (en)

[origin: WO2014173837A1] The invention relates to an electrostatic spray device for spraying a liquid coating product, comprising a rotating bowl (20) and means (42) for driving said bowl around a rotational axis (X 30), the bowl defining a concave surface (212) for the distribution of the coating product and an edge (214) which limits an area (Z 2) for the spraying of the coating product. Said spray device is provided with at least one electrode (22) that charges by means of ionisation of drops (3000) of the coating product. Said electrode (22) charging by means of ionisation is arranged, in relation to the edge (214) and along the rotational axis (X 30), opposite the spray area (Z 2), between the edge and the means (42) for driving the bowl (20). A second electrode (70) mounted on a stationary body (30) allows the creation of an electrostatic field for transporting drops. A third electrode (90), which is also mounted on a stationary body, is brought to an intermediate potential between those of the first and second electrodes (22, 70) during the operation of the spray device.
