TWO-PIECE ROTOR FOR WANKEL ENGINES ABSTRACT OF THE INVENTION A unique two piece rotor construction and method of fabrication is disclosed. The rotor is cast in split positions (bifurcated along a central plane) by a shell molding or high pressure green sand technique. The portions have special pairs of interfitting mating faces, at least one being generally radially directed and at least one being generally axially directed. After the cast portions have said inter- fitting faces machined to a predetermined finish, and cleansed. The portions are assembled in a fixture with flux and braze material between said faces.
