ABSTRACT:
A portable liquid dispensing device for delivering drinking fluids for consumption. A rechargeable battery powered pump is selectively actuated and controlled on demand through a manual actuator, and in-line check valve, and a pressure switch. The pump is attached to a portable storage vessel. When actuated, the pump evacuates the liquid through the vessel wall and fills a pipe segment. An in-line check valve holds terminal fluid pressure in the pipe downstream of the pump, and a pressure switch detects the liquid pressure in such pipe section. Multiple tubing sections transport the liquid to one or more dispensing valves.
