ABSTRACT:
A coating material dispensing system includes an electrostatic high potential supply having an output terminal on which the supply maintains a high electrostatic potential, a source of coating material, a dispenser for dispensing the coating material, and appropriate fluid and electric circuits for coupling the dispenser to the source of coating material and the output terminal to the dispenser to supply potential to the coating material dispensed by the dispenser. The fluid circuit coupling the dispenser to the source of coating material includes a peristaltic voltage block having multiple coils of a resilient conduit and a rotor for supporting an element for contacting each coil at multiple contact points. The peristaltic voltage block substantially divides the flow of coating material to the dispenser into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material supply.
