ABSTRACT:
A solar-powered pump particularly suited for intermittently delivering a stream of water. The pump is characterized by a housing adapted to be seated in a source of water having a water discharge port disposed above the water line of the source, a sump including a valved inlet port through which water is introduced to the sump, disposed beneath the water line, a displacer supported for vertical reciprocation in said housing, an air passageway extended between the vertically spaced faces of the displacer, a tipple disposed adjacent to the water discharge port adapted to be filled in response to a discharge of water from the housing, and a line so interconnecting the tipple and the displacer that the displacer is moved upwardly in response to a filling of the tipple and moved downwardly once water is discharged from the tipple. Air above the displacer is expanded in response to solar energy impinging on the housing, transferred into pressurizing relation with the sump for forcing water from the sump, while the sump subsequently is depressurized for charging in a response to a lifting of the displacer, and a cooling of the air in the housing as it is displaced to the lower part of the housing.
