Abstract (en)

[origin: WO9500250A1] Electrostatic spraying device, for spraying a coating product in powder form, comprising a coating product feeding tube (2) opening axially at the bottom of a rotary spray head (3), characterized in that a slug (30), axially mounted on said spray head, is electrically engaged with a fixed portion (26) of the spraying device, the fixed portion being electrically conductive and connected to a high voltage feeding circuit (22, 23, 24, 25). By means of the invention, the high voltage may be applied on the rotation axis (XX') of the spray head at a location compatible with the central feeding of the coating product into the spray head.
