Beschreibung
Zusammenfassung:	This invention relates to an electrostatic spray gun for the atomization and spraying of coating products. The gun includes an electro-aerodynamic generator having a conduit for the flow of a gaseous fluid at least partially at supersonic speed from an upstream convergent-divergent region containing ionization means to a downstream zone at high potential adjacent the atomization nozzle. According to the invention, means for shutting of the flow of gaseous fluid are arranged downstream of the electro-aerodynamic generator, for example on the nozzle body. The electro-aerodynamic generator is preferably constructed as a removable cartridge, and means are also provided for adjusting the angle and velocity of the output spray from the gun.
