ABSTRACT:
A fluid pump apparatus includes an elongated chamber within which a pair of pistons are movable. The chamber includes an intermediate inlet and outlets at the ends thereof. The pistons are formed of para-magnetic material and include passageways for providing fluid communication between the inlet and the outlets. An external magnetic drive system oscillates the pistons back and forth within the chamber, and includes two pairs of electrically conductive windings, wherein each pair surrounds the chamber at a position between the inlet and one of the outlets. The windings are energized in such a way that they cause the pistons to oscillate in unison with one another. Valves are provided for permitting fluid flow through the passageways in a direction from the inlet toward the outlets, and for permitting fluid flow from the chamber through the outlets. These valves also prevent fluid flow in the reverse direction.
