Water-Powered Pump For Use In Irrigation And For Other Purposes

US Patent:
2012030, Dec 6, 2012
Filed:
Jun 2, 2011
Appl. No.:
13/152228
Inventors:
Joost Brender A. Brandis - Wilmington DE, US
Jeffrey Lynn McKay - Wilmington DE, US
International Classification:
F04B 35/02
US Classification:
417375
Abstract:
The present invention is directed to a water pump that may be easily constructed from inexpensive parts and materials and that is powered by the water source from which the water to be pumped is drawn. In a preferred embodiment, two pairs of lever arms located on opposite sides of the pump are alternately filled with water from the source and then emptied causing the lever arms to alternately ascend and descend. As the lever arms ascend and descend, they alternately fill and then compress a pair of pistons causing water to be pumped to an outlet of the pump. Water from the emptied lever arms may preferably be returned to the source, thus minimizing any impact of the pump on the environment and downstream users of the water source.
