<p>A peristaltic voltage block (34) for use in systems for electrostatically (48) aided atomization (10) and dispensing of conductive coating materials includes a resilient, electrically non-conductive conduit (78, 220) arranged in multiple loops (82, 222) on a support mechanism (80, 224). The voltage block (34) also includes contactors (92, 250) for contacting the conduit (78, 220) substantially to occlude the conduit (78, 220) to divide coating material flowing in the conduit (78, 220) into discrete slugs, and a rotor (108, 246) supporting the contactors (92, 250). A mechanism (136, 138, 140, 142, 144; 100, 106, 124, 125, 127, 128, 132, 135, 146, 152, 160; 252, 264, 267, 273, 274) is provided for selectively moving the contactors (92, 250) into and out of occluding engagement with the conduit (78, 220). <IMAGE></p> |
