Abstract

Eine elektrostatische Sprühvorrichtung zum Aufbrin­ gen eines flüssigen Überzugsmaterials auf ein Werkstück, mit einem rotierenden, glocken- oder scheibenartigen Zer­ stäuberkopf und einem zum Zerstäuberkopf koaxialen, an eine Druckluftquelle angeschlossenen Ringspalt wird derart weiter ausgebildet, daß ein weiterer an eine Druckluftquelle angeschlossener Ringspalt vorgesehen ist, der als äußerer Ringspalt den ersten, inneren Ringspalt koaxial umgibt, und daß die Spaltbreite zumindest des einen der beiden Ring­ spalte verstellbar ist. An electrostatic spray device for application liquid coating material onto a workpiece, with a rotating, bell-like or disk-like Zer atomizer head and one coaxial to the atomizer head an annular gap connected to a compressed air source becomes such further trained that another to a compressed air source Connected annular gap is provided, which is the outer Annular gap coaxially surrounds the first, inner annular gap, and that the gap width of at least one of the two ring column is adjustable.
