Abstract

See full text

A mobile sprayer apparatus includes a direct current electrical supply, and a supply conduit operative to supply pressurized liquid to a plurality of nozzle assemblies. Each nozzle assembly comprises a channel connecting the supply conduit to a nozzle, a valve operative to selectively open and close the channel, and a solenoid coil operative to selectively move the valve to an open position when a direct current electrical pulse is connected to pass through the solenoid coil in a first direction, and to selectively move the valve to a closed position when a direct current electrical pulse is connected to pass through the solenoid coil in an opposite second direction. A switch selectively delivers a pulse of electrical energy through each solenoid coil in the first direction or through each solenoid coil in the second opposite direction, and no electrical energy is delivered to the solenoid coils between pulses.
