ABSTRACT:
A pump mechanism adapted to float on a reservoir of water characterized by a floating enclosure provided with an internal chamber, a float disposed within the chamber of the enclosure, a first valve coupled to the float and adapted to open and close an orifice provided at the top of the enclosure, a refill valve associated with an orifice provided at the bottom of the enclosure, and an output tube opening on the chamber of the enclosure and provided with a check valve to prevent the back flow of water into the chamber. As the air within the chamber expands the water within the chamber is expelled through the output tube causing the enclosure to float higher on the reservoir and the float to float lower within the enclosure. When the water level within the enclosure drops to a predetermined level, valves open to recharge the mechanism with water and cool air.
