Abstract
A spray nozzle for electrostatic spraying of a coating product including a needle forming a mobile shutter of a valve for controlling the spraying, which is positioned in a recess of a barrel of the nozzle. The recess defines a surface for guiding the axial translation of the needle along a longitudinal axis of the recess. The needle includes a front shaped for abutting a seat to obstruct a duct for flow of the coating product, a rear portion which interacts with means for controlling the translation of the needle and a central portion comprised between the front end and the rear portion, while a high-voltage unit included in the nozzle is capable of applying a high-voltage to the front end of the needle. A raised portion provided on the central portion of the needle, inside the recess, can increase the electric creepage distance along the central portion.
