Abstract
The inventive device for electrostatically projecting a coating product comprises a spray gun provided with voltage increasing means for producing a high direct voltage for a product electrostatic charge, wherein said spray gun is provided with a controllable valve for controlling an atomizing air flow inside the spray gun in the direction to a spraying head. A pressure sensor integrated into the spray gun is used for detecting the atomizing air pressure (P) representative value downstream of the valve and for delivering a signal (S) for controlling the power supply of the voltage increasing means. Said invention makes it possible to control the power supply of the voltage increasing means according, in particular, to the signal (S) received from the sensor.
