Abstract: A liquid spraying system having an electrically operated pulse width modulation control for directing a modulated liquid discharge based upon frequency and duty cycle of a reciprocally operated liquid control valve. The spray nozzle assembly includes a nozzle body having an inwardly converging conical chamber communicating between an upstream liquid directing plate and a downstream liquid discharge passage. The liquid directing plate is formed with a one or more rings of circumferentially spaced liquid directing passages angularly oriented with respect to a central liquid flow axis of the nozzle body for directing liquid discharging from said nozzle body discharge passage into a predetermined conical spray pattern.
