Abstract
A pump, including: inner gerotor; a crankshaft; an outer gerotor; an inlet assembly with inlet ports; an outlet assembly with outlet ports; and magnetic actuators. The inner gerotor includes lobes and a central opening. The crankshaft: passes through the central opening; is rotatable about an axis of rotation; and includes a first longitudinal axis not co-linear with the axis of rotation. The outer gerotor includes recesses. The magnetic actuators are sequentially energized to create magnetic fields to displace the inner gerotor with respect to the crankshaft to: displace a first lobe out of a first recess and draw fluid through an inlet port into the first recess; and displace a second lobe into a second recess and expel second fluid out of the second recess and through an outlet port.
