ABSTRACT:
A pump and method for delivering a cooling fluid from a reservoir of fluid to a destination is disclosed. The pump comprises a vessel for holding fluid to be delivered, the vessel being submersible within the reservoir. The vessel has a fluid inlet near its bottom for receiving fluid from the reservoir and a gas discharge outlet near its top. The pump has an inlet valve for preventing fluid from flowing out of the vessel through the fluid inlet, and a gas discharge valve for opening and closing the gas discharge outlet. The discharge valve is responsive to the level of fluid within the vessel. The pump also comprises a conduit for conducting fluid from inside the vessel to its destination, and heating means for evaporating the fluid within the vessel. This heating creates a pressure head within the vessel when the gas discharge outlet is closed thereby causing the fluid to flow through the conduit.
