ABSTRACT:
A boilerless steam displacement pump for pumping water is disclosed which uses steam not only to displace water from a chamber to pump the water but also uses the pressurized steam to charge and energize an internal water-to-steam delivery system in order to present water to the steam generating chamber without the use of any auxiliary pump. In this way steam being generated intermittently is used in one period of a cycle to supply water under pressure to the water-to-steam delivery system and then this system delivers the pressurized water to the steam generating chamber during an alternate period to produce the succeeding surge of steam.
