ABSTRACT:
A positive displacement device is presented. The mechanism comprises a nutator capable of nutating within a nutating chamber defined by the interior surface of the body of the positive displacement device between an inlet into and an outlet out of the positive displacement device, an inverted pendulous, low friction, substantially non-sliding nutator, vertically elongated double pivoting fulcrum; a magnetic signal pickup mechanism comprising a pivoting cruciform shaped magnet element low inertia wire magnetically tracking a nutator and a means of sensing movement; a third magnetic element to dampen or amplify movement of the cruciform wire; a balance plate bearing on the basic elements of the positive displacement device by means of a resilient spring force; and static elements which provide magnetic attraction to the moving elements effecting a sealing influence between the static and moving elements.
