SPRAYER NOZZLE SYSTEM FOR VARIABLE APPLICATION RATES

摘要

In a sprayer nozzle apparatus a pressurized liquid source directs pressurized liquid through a supply conduit and a supply port connects the supply conduit to first and second nozzles oriented such that spray patterns dispensed thereby do not intersect. First and second pressure sensors send pressure signals to a controller indicating first and second operating pressures at the nozzles. First and second pressure regulators vary the corresponding operating pressures in response to a control signals received from the controller to vary the dispensing rate of the first and second nozzles.

主权项

1. A sprayer nozzle apparatus comprising:
a pressurized liquid source directing a flow of liquid at a selected supply pressure through a supply conduit; a supply port connecting the supply conduit to corresponding first and second input ports of first and second nozzles; wherein the first and second nozzles are oriented in corresponding first and second operating positions such that a first spray pattern dispensed by the first nozzle does not intersect a second spray pattern dispensed by the second nozzle; a first pressure sensor sending a first pressure signal to a controller indicating a first operating pressure at the first input port and a second pressure sensor sending a second pressure signal to the controller indicating a second operating pressure at the second input port; a first pressure regulator operative to vary the first operating pressure in response to a first control signal received from the controller to vary a dispensing rate of the first nozzle, and a second pressure regulator operative to vary the second operating pressure in response to a second control signal received from the controller to vary a dispensing rate of the second nozzle.
