Abstract

A device for feeding an electrically conductive coating material from a supply system to a coating material dispensing device wherein a high electrostatic potential is maintained between the supply system and the device, comprising an intermediate storage container fillable in controlled manner from the supply system to a maximum fill level and connected to the coating material dispensing device by a coating material conduit maintained at substantially the electrostatic potential of the coating material dispensing device, a device provided in the intermediate storage container for breaking up the supply of coating material into the intermediate storage container into electrically separated individual particles, and means for coupling the breakup device to a source of coating material, the breakup device being arranged above the fill level such that, between the breakup device and the interior of the intermediate storage container, a minimum spacing is maintained so that no electrostatic discharge occurs.
