Abstract

See full text

A positive displacement inductive pump includes a central piston formed of a ferromagnetic material having non-ferromagnetic end pistons that extend from each of its opposite ends. Stationary end walls are mounted to opposite ends of a housing and are centrally bored. First and second inductive coils are alternately energized, causing the central piston and the end pistons to conjointly reciprocate within an axial bore and the end wall central bores, respectively. First and second check valves are positioned outboard of each end wall and allow valve-controlled ingress and egress of material into and out of the axial and central bores. The relative diameters of the central piston and the end pistons are changed to control the relationship between the magnetic force applied and the output pressure for a given volume of fluid.
