Patent number: 12186767Abstract: 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.Type: GrantFiled: January 14, 2022Date of Patent: January 7, 2025Assignee: Wilger Industries Ltd.Inventor: Wilfred H.

Patent number: 10845228Abstract: A flow meter has a meter wheel housing connectable in-line in a liquid conduit such that liquid flows through the meter wheel housing from an input port to an output port. Liquid flowing from the input port to the output port rotates a meter wheel mounted in the housing, and a wheel sensor measures rotational speed of the meter wheel. A first jet member defining a first orifice with a first cross-sectional area is movable into a jet operating position between the upstream end of the liquid conduit and the input port such that liquid passes through the input port into the meter wheel housing only through the first orifice. A second jet member defining a second orifice with a second cross-sectional area is movable into the jet operating position. The second cross-sectional area is less than the first cross-sectional area.Type: GrantFiled: October 27, 2017Date of Patent: November 24, 2020Assignee: Wilger Industries, Ltd.Inventors: Wilfred H.

Patent number: 10462985Abstract: A nozzle body apparatus having a conduit mounting member with a conduit input adapted to be connected such that liquid passing through a liquid conduit flows into the conduit input and out through a conduit output. A component mounting member has a component input releasably connected to the conduit output, a component attachment element, and a component output. Liquid passing out the conduit output flows into the component input then through a sprayer component connected to the component attachment element to the component output and then to a nozzle. The component mounting member is connectable to the conduit output in a first orientation where the component attachment element extends from the conduit output in a first direction, and is connectable to the conduit output in a second orientation where the component attachment element extends from the conduit output in a second different direction that is different from the first direction.Type: GrantFiled: February 15, 2018Date of Patent: November 5, 2019Assignee: Wilger Industries Ltd.Inventor: Wilfred H.
