Abstract
A liquid dispensing system for dispensing highly viscous liquids such as lubricating oil. The system includes a nozzle body and elongated electrode that define an annular liquid flow passage communicating with a protruding conically configured terminal end of the electrode. An end cap of the nozzle body defines a plurality of circumferentially spaced discharge orifices about the electrode for controlling the discharge of electrically charged liquid onto the terminal end of the electrode for direction therefrom in a thin line, having a width of less than 0.06 inches.
Claims18
A liquid dispensing system for dispensing highly viscous liquid onto a target area comprising;
- a hydraulic electrostatic spray nozzle assembly having a nozzle body;
- an elongated electrode supported within said nozzle body for coupling to an electrical supply and having terminal end protruding in a downstream direction from said nozzle body;
- a supply of highly viscous liquid having a viscosity of between 75 cP and 535 cP;
- said nozzle body and elongated electrode defining an annular liquid flow passage about said electrode communicating with the downstream terminal end of said electrode;
- said nozzle body having a liquid inlet coupled to said supply of highly viscous liquid for directing said highly viscous liquid through said annular liquid flow passage between said electrode and nozzle body for electrostatically charging the highly viscous liquid;
- and
- said nozzle body having a downstream end that defines a plurality of circumferentially spaced metering orifices about said electrode for controlling the discharge of the electrostatically charged liquid onto the protruding terminal end of said electrode for direction therefrom in a thin line of viscous liquid onto the target area without prior pressurized air atomization of the liquid.
A lubricant dispensing system for dispensing lubricant onto a target area comprising;
- a hydraulic electrostatic spray nozzle assembly having a nozzle body;
- an elongated electrode supported within said nozzle body for coupling to an electrical supply and having a conically configured downstream terminal end tapered inwardly in a downstream direction protruding outwardly from said nozzle body;
- a supply of oil;
- said nozzle body and elongated electrode defining an annular liquid flow passage about said electrode communicating with the downstream terminal end of said electrode;
- said nozzle body having a liquid inlet coupled to said supply of oil for directing oil through said annular liquid flow passage between said electrode and nozzle body for electrostatically charging said oil;
- and
- said nozzle body having a downstream end that defines a plurality of circumferentially spaced metering orifices about said electrode for controlling the discharge of the electrostatically charged oil onto the protruding terminal end of said electrode for direction therefrom in a thin line of oil onto a target area without prior pressurized air atomization of the oil.
