ABSTRACT:
The intermittent generation of steam by a solar heat source provides a reciprocating column of water when the steam pressure acts on the top of a water column and the column in turn causes a diaphram in a chamber first to expand into an adjacent chamber when the water in the column is placed under pressure and then secondly to contract when the pressure is relieved and thereby the expanding and contracting cavity experiences a pressure which expells water from the cavity through a check valve as the cavity contracts and subsequently as the pressure is relieved the vacuum formed in the cavity as it expands draws in water through another check valve for later expulsion. The reciprocating action of the water in the column that moves the diaphram into and out of the pumping chamber is caused by alternating surges of steam in which the pressure is increased when water from a reservoir in constant fluid flow communication with a steam generating chamber is periodically caused to flow to the steam generating chamber and then impeded from flowing to the chamber. In a principal embodiment the water reservoir is elevated over the steam generating chamber and the means of providing intermittent water flow to the steam generating chamber is gravity flow controlled by a valve.
