Patent ID: 8241013

Claim:
A device for propelling fluids comprising: a. at least one first pump assembly having a primary pump, an accumulator pump and valve means; i. said primary pump having a primary housing a primary piston and primary drive means, said primary housing having a primary opening and primary chamber, said primary opening in fluid communication with said primary chamber and said primary piston movable within said primary chamber to move fluids through said primary opening and said drive means mechanically linked to at least one of said primary piston and primary chamber to power said primary piston in a loading movement and a pump movement; ii. said accumulator pump having an accumulator housing, accumulator piston and accumulator drive means, said accumulator housing having an accumulator opening and accumulator chamber, said accumulator opening in fluid communication with said accumulator chamber and said accumulator piston movable within said accumulator chamber to move fluids through said accumulator opening, and said accumulator drive means mechanically linked to at least one of said accumulator piston and accumulator chamber to power said primary piston in a loading movement and a pump movement; iii. said valve means in fluid communication with said accumulator opening and said primary opening, and said valve means having a first outlet and a first inlet, and at least a first position and a second position, said inlet for receiving fluid and said outlet for discharging fluid, in said first position said accumulator opening and said first outlet are in fluid communication and said primary opening is in fluid communication with said first inlet, and upon said accumulator pump assuming said pump movement said first outlet discharging fluid and upon said primary opening assuming said loading movement said primary chamber filling with fluid; and in said second position said primary pump opening, accumulator pump opening and first outlet are in fluid communication and upon said primary pump assuming said pumping movement and said accumulator pump assuming said loading movement said accumulator chamber filling with fluid and said first outlet discharging fluid, said valve means moving between said first position and said second position as said accumulator pump and primary pump alternate between a loading movement and a pump movement; and b. control means, said control means in signal communication with said accumulator pump, said primary pump and said valve means, said control means commanding said accumulator pump to assume said loading movement and said pump movement and said primary pump to assume said loading movement and pump movement in coordination with said movement of said valve means such that fluids are propelled from the first outlet.
