Abstract:
A fluid-dispensing system comprising:A) a liquid container forming a container outlet and a liquid reservoir containing a liquid to be dispensed;B) a pressurizer cartridge containing a pressurizing fluid under a source pressure at least eight times as high as the pressure that prevails in the liquid reservoir;C) a pressurizer passage that conducts the pressurizing fluid from the pressurizer cartridge at an upstream end thereof to the liquid container at a downstream end thereof to pressurize the liquid reservoir and thereby tend to urge through the outlet the liquid to be dispensed;D) a pressure regulator that permits the pressurizing fluid to flow through the pressurizer passage from the pressurizer cartridge to the liquid only when the fluid pressure downstream thereof does not exceed a predetermined limit pressure less than the source pressure; andE) an electric valve operable by application of electrical control signals thereto between an open state, in which the electric valve permits fluid flow through the outlet, and a closed state, in which it prevents fluid flow through the outlet.
