Abstract
An example apparatus includes an outer rotor having a first axial face and a second axial face opposite the first axial face, wherein the first axial face comprises a circumferential contour defining a plurality of lobe faces, and wherein the second axial face comprises a transformed circumferential contour defining a corresponding plurality of lobe faces, where the transformed circumferential contour comprises at least one of a scale transformation of the circumferential contour or a rotational transformation of the circumferential contour; and an inner rotor configured to rotate eccentrically within the outer rotor, thereby forming a gerotor element for a fluid pump.

An apparatus comprising:
- an outer rotor having a first axial face and a second axial face opposite the first axial face, wherein the first axial face comprises a circumferential contour defining a plurality of lobe faces, and wherein the second axial face comprises a transformed circumferential contour defining a corresponding plurality of lobe faces;
- wherein the transformed circumferential contour comprises at least one of a scale transformation of the circumferential contour or a rotational transformation of the circumferential contour;
- and
- an inner rotor configured to rotate eccentrically within the outer rotor, thereby forming a gerotor element for a fluid pump.
A method, comprising:
- preparing an outer rotor having a first axial face and a second axial face opposite the first axial face, wherein the first axial face comprises a circumferential contour defining a plurality of lobe faces, and wherein the second axial face comprises a transformed circumferential contour defining a corresponding plurality of lobe faces;
- preparing an inner rotor configured to rotate eccentrically within the outer rotor, thereby forming a gerotor element for a fluid pump.
A pump assembly, comprising:
- an inner element and an outer element, wherein the inner element and outer element are configured to rotationally engage thereby forming a plurality of dynamically changing pumping volumes;
- wherein at least one of the inner element or the outer element comprises a rotor;
- and
- wherein a major diameter of the rotational engagement between the inner element and the outer element comprises a Z-axis variability.
