Abstract
A uniform distribution nozzle for electrostatic dispensing of conductive fluids, wherein the nozzle includes a nozzle body having a base and an attached cap, and an inlet for receiving fluid at a relatively low pressure. A substantially elongated outlet opening is provided on the nozzle for enabling distribution of the fluid, and a conductive shim is preferably included for providing an electrical charge to the fluid to enable electrostatic distribution from the nozzle. In a preferred embodiment, a plurality of distribution channels are provided to define discrete pathways within the nozzle for distributing and directing the fluid from the inlet to predetermine dispensing points along the outlet opening. The pathways have substantially equal flow characteristics, so that fluid travels with substantially equivalent volume, speed and pressure between the inlet and the outlet opening, regardless of which particular pathway and dispensing point are involved. The distribution channels are part of the overall distribution chamber provided within the nozzle for receiving conductive fluid and directing it to the outlet opening in a uniform and consistent manner.
