PCT No. PCT/JP90/00857 Sec. 371 Date Sep. 7, 1993 Sec. 102(e) Date Sep. 7, 1993 PCT Filed Jun. 30, 1990 PCT Pub. No. WO92/06146 PCT Pub. Date Jan. 9, 1992A device electrically insulates the supply of paint for an electrostatic paint sprayer from the charged paint near the sprayer. In the electrostatic paint sprayer, the paint that is sprayed from a nozzle is charged to a high potential. Because the paint is electrically conductive, the charged paint will conduct charge toward the supply. The present invention runs the paint supply through a vessel of insulating material. The vessel has baffles with openings that divide the flow into droplets, thus creating a discontinuity in the supply stream. Charge accumulated on the interior wall of the vessel attracts oppositely charged droplets, causing them to accelerate and splatter against the interior wall. The resulting coating of electrically conductive paint on the interior wall can create an electrically conductive bridge that destroys the insulating effect of the device. To prevent charge from accumulating on the interior wall, conductors are placed on the outside of the vessel to bleed charge from the accumulated paint through the insulated vessel wall, thus lowering the potential of the interior wall and lessening the attraction for droplets and the attendant splatter caused by acceleration of droplets toward the wall.
