Abstract

The present invention relates to a flow control system for sprayer nozzles. The control system includes a solenoid coil and a solenoid plunger. The solenoid plunger can slide into an adapter body, substantially perpendicular to the direction of fluid flow. In reducing the fluid flow through the nozzle, the plunger is moved to block an orifice in the path of the fluid flow, within the adapter. The plunger movement is achieved through the energization of the solenoid coil, with signals sent by a controller. The orifice in the adapter is manufactured to a specific size which allows reduced power consumption to shut off or reduce flow through the nozzle. Also, the orifice is sized to provide unrestricted flow when fully open. By means of the controller, control can be provided individually to each nozzle from a plurality of nozzles on a spraying bar. In one aspect of the invention, the flow control system can be used on agricultural sprayers with sensing equipment such as cameras that may determine the green condition of the foliage being sprayed. According to the determined condition, the controller would regulate the flow through the nozzles in the corresponding area of the field. The control valve adapts to industry standard fittings and adapts to a position on the fittings so the spray fluid passes through the filter and nozzle check valve before passing through the control valve while the nozzle check valve remains in place. Specifically, the control valve can be adapted onto a standard fitting and inserted between the nozzle screen and spray tip.
