    Abstract: A fluid ejector for ejecting discrete volumes of ejectant includes a body with opposing first and second surfaces. One or more nozzles are defined as conduits extending through the body between the surfaces to connect first and second orifices at the first and second surfaces respectively. The fluid ejector further includes a gas supply means having a gas outlet and an ejectant supply means. The ejectant supply means supplies the ejectant to the nozzles at a pressure above ambient via their supply orifices. The supply orifice is defined in a conduit's side or is the second orifice. Relative movement of the gas supply means and body exposes first orifices to the gas outlet allowing the gas supply means to supply gas at a pressure above ambient, wherein a pressure difference thereby created between the first and second orifices causes ejection of the ejectant from the nozzles through the second orifices.

    Abstract: A spray gun includes a gun body and valves configured to control flow of material and air through the gun body. A trigger is mounted to the gun body and is disposed relative to the valves such that the trigger actuates the valves in sequence to begin air flow and material flow. A sensor senses when the trigger is in an actuated state and the sensor causes a pump to begin pumping material to the spray gun. Release of the trigger causes the trigger to leave the actuated state. A detent mechanism holes the trigger in a detent state intermediate the actuated state and a resting state. The sensor does not sense the trigger with the trigger in the detent state. The trigger maintains the valves open with the trigger in the detent state.

    Abstract: A dual mode spray gun has a mixing valve with two inlets and two outlets. A handle assembly extending proximally from the valve couples the first inlet to pressurized water and provides means for manually starting and stopping flow. The second inlet draws detergent from a reservoir mounted to the valve. A barrel extending distally from the valve terminates at spray and foam ports connected respectively to the first and second outlets via first and second channels formed through the barrel, the second channel defining an aeration port upstream of the foam port. A mode switch on the mixing valve in a first position allows flow from the first inlet to the spray port, stops flow from the second inlet and stops flow to the foam port, and in a second position stops flow to the spray port and allows flow from the first and second inlets to mix and aerate en route to the foam port.
