Abstract
A fluid delivery system includes a pump, a fluid conduit and a regulated gas inlet. The fluid conduit has an upper end connected to the pump and a lower end in communication with a fluid supply. The regulated gas inlet includes a gas supply at a first pressure; a pressure monitoring conduit in fluid communication with the fluid conduit between its upper and lower ends; a gas delivery conduit in communication with the fluid conduit; and a pressure-responsive valve. The valve is connected to the pressure monitoring conduit and moves between a closed position wherein gas flow into the fluid conduit is restricted, and at least one open position wherein gas is delivered to the fluid conduit through the gas supply conduit. The valve is normally biased toward the closed position but moves opens when pressure within the pressure monitoring conduit is below the first pressure by more than a predetermined level.
