Abstract
A fluid pump is arranged to employ cooperating gears that are arranged for axial displacement relative to one another, whereupon a volumetric chamber positioned between a surrounding housing and one of a plurality of inter-nesting first and second cylindrical housings permits displacement of the first and second cylindrical housings towards one another that in turn effects axial displacement of the gears relative to one another to control inter-engagement and associated volumetric displacement relative to the gear structure.
