ABSTRACT:
An off center one spot nutator fulcrum rocking bearing assembly is presented. The assembly comprises a non rotating circular cylindrical fulcrum rod coupled at each end to a selected fixed point inside a nutating pump chamber. An off center non rotating rocking nutator fulcrum bearing has an interior circular cylindrical surface rotatably mating with and coupled around the exterior circular cylindrical surface of the rod, the bearing having at least two exterior surfaces parallel to the bearing axis including a first generally planar bearing surface parallel to the bearing axis and disposed closer to the bearing interior surface than any other bearing exterior surface parallel to said axis wherein said first bearing surface slideably nutatably couples to a nutator barrier, whereby the barrier rides on the first bearing surface during nutation causing the bearing to rock.
