Abstract (en)

[origin: WO9704876A1] Air-atomizing induction-charging spray nozzles suited for use with conductive liquids, solutions, suspensions or emulsions. These systems feature a high level of spray charging at low induction-electrode voltage and current. Primary benefits include consistent, reliable operation in harsh agricultural and industrial environments with a wide range of spray formulations, especially those having relatively high concentrations of abrasive and conductive materials. The outer surfaces of the nozzles' body portion (1), near connections to earthed sprayer parts, are maintained floating or at near ground potential. The cover portion (2) surfaces adjacent to the induction electrode (18) are maintained at near the potential of the electrode (18). A highly resistive path between the high and low voltage portions of the nozzle is maintained and the electrode voltage or spray charge level does not decrease significantly as nozzle surfaces become coated with spray or are otherwise contaminated by conductive materials present in the spraying environment.
