ABSTRACT:
In this solar steam driven water pump steam is periodically generated and then condensed within a cavity to produce first a period of pressure over a column of water and then a period of vacuum to thereby first expell water from the cavity through one check valve and to subsequently fill the cavity with water through another check valve at the time of the vacuum, the generation of said steam pressure within said cavity being effected by a separate small pump within the cavity when this pump moves a small quantity of water in the cavity to a solar heated chamber in the cavity and the subsequent effecting of the vacuum within said cavity being accomplished when the water pumping chamber is cooled by condensation of the steam on the column of water against which it is acting, the periodic cessation of the small pump causing steam generation to cease when thermostats contacted by hot steam as water is expelled from the water chamber open a circuit stopping the small pump.
