A differential fluid pressure energy conversion system includes a valve (V1) for regulating an input from a pressure source to define a fluid flow; and a lower piston chamber (LPC) in fluid communication with an output of V1, the LPC disposed about a central vertical axis of the system; Further included is a double acting reciprocatable piston (DAP) having an integral lower portion (P1) and an integral upper integral portion (P2), each portion having a bottom radial surface area, the radial surface area of P1 greater than that of P2, an outer peripheral edge of the P1 in fluid-tight slidable continuous contact with an inner complemental surface of LPC, DAP further including an elongate axial channel, co-axial with the vertical axis of the system, the channel extending an entire axial length of the DAP. Also included is an upper piston chamber (UPC) disposed in vertical axial alignment with the system axis and without fluid communication with the LPC, an inner surface of the UPC in fluid-tight slidable continuous contact with a complemental peripheral edge of the P2 of the DAP. The system also includes a valve (V2) within the axial channel of the DAP, the valve effecting closure of the channel during each upstroke of the DAP and opening of the axial channel during each downstroke; and a fluid exit port in fluid communication with the UPC disposed above a greatest extent of upward travel of the DAP, the port permitting release, to an ambient atmosphere, during upward axial displacement of the DAP, of pressurized fluid injected through the axial channel into the UPC during downward axial displacement of the DAP when the valve V2 is open, whereby a ratio of pressure of the fluid in the UPC relative to that in the LPC is generally determined by the ratio of the lower radial surface area of P1 to that of P2. |
