Steam Operated, Self Cycling, Diaphragm Water Pump

US Patent:
2016029, Oct 13, 2016
Filed:
Apr 21, 2016
Appl. No.:
15/135058
Inventors:
Jennifer Williams - North Hollywood CA, US
Craig Duda - North Hollywood CA, US
International Classification:
F04B 9/127
Abstract:
A diaphragm pump mechanism is powered by steam generated by an internal heater coil heating the pumped water, which moves the diaphragm and an attached piston to pump water through the pump. The heater coil is turned on-and-off using a switch that is timed to the movement of the pump. The water is pumped through a series of one-way rubber valves and reed valves to prevent a back flow of water. The pressure generated by the steam is released when a reed valve located on the diaphragm makes contact with a pin located on the body of the pump, opening the reed valve and allowing the steam to travel through and to condense. The piston and diaphragm are returned to the starting position when the steam pressure is released by a spring attached to the pump shaft. On the return stroke an accumulator refills the diaphragm chamber with water.
