Claim Text:
1. A high flow electrostatic sprayer comprising: a bar comprising a tube defining a hollow internal space that is sealed at opposite first and second ends, said tube adapted to receive pressurized air from an associated source into said internal space; a plurality of nozzle bodies connected to said tube, each of said nozzle bodies electrically connected to said bar for receiving a high voltage positive electrical charge from said bar, wherein each of said nozzle bodies comprises an inlet in communication with the internal space and an outlet located external to said internal space and an internal channel that connects said inlet to said outlet such that pressurized air within said internal space of said tube can flow outwardly through each of said nozzle bodies; a water conduit located within the internal space of the tube and adapted to be connected to an associated source of water, said water conduit supported within said internal space of said tube by a plurality of internal supports, wherein the water conduit comprises an electrical ground path; a plurality of capillary tubes each in fluid communication with said water conduit and each also electrically connected to said ground path of said water conduit, wherein said plurality of capillary tubes are located respectively within the internal channels of the plurality of nozzle bodies such that liquid ejected by said capillary tubes within the respective internal channels will be micronized into droplets by pressurized air flowing from the inlet of the nozzle to the outlet of the nozzle and said micronized droplets will be ejected from said outlet of said nozzle; a bar support that is connected to the bar but electrically isolated from the bar, said bar support adapted for connection to an associated sprayer machine structure, wherein said bar support is electrically connected to said ground path of said water conduit to form part of said ground path, wherein pressurized air from the internal space of the tube is discharged to the exterior of the tube through the nozzle bodies that are connected to the high voltage positive electrical charge and said pressurized air flowing through each of said nozzle bodies micronizes liquid flowing from the respective capillary tube located in said internal channel of said nozzle body to form negatively charged micronized liquid droplets that are discharged from said outlet of the nozzle body with said pressurized air.
