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.
