Abstract

See full text

In the assembly to give potential compensation at an electrostatic rotation atomizer, for paint spraying, the shaft (1) has an external or direct charge. Ring or spiral pointed edges (8,9) face each other at the outer surface of a part (1') of the shaft and in the inner surface of a fixed section (4) of an air bearing (3) charged with the required potential, with opposing pitches so that the edges intersect each other at points which shift with the shaft rotation. The housing (2) is insulated (12) from the earthed potential compensation housing (4). The housing is earthed at a high-ohm resistance (13).
