Abstract

Elektrostatische Sprühbeschichtungsvorrichtung mit einem Sprühdüsenkörper (32), welcher derart geformt ist, daß an ihrer Sprühöffnung (34) ein Versprühen oder Zerstäuben des Beschichtungsfluides stattfindet. Der Sprühdüsenkörper (32) ist drehbar angeordnet, so daß die versprühten Fluidpartikel radial nach außen getrieben werden und sich dadurch in der versprühten Fluidwolke gleichmäßig verteilen.

Figure 00000001
Electrostatic spray coating device with a spray nozzle body (32) which is shaped such that spraying or atomization of the coating fluid takes place at its spray opening (34). The spray nozzle body (32) is rotatably arranged so that the sprayed fluid particles are driven radially outward and are thereby distributed evenly in the sprayed fluid cloud.
