ABSTRACT:
A rotary fluid displacement device having no indexing gearing between the rotor and the crankshaft therefor. Housing and rotor shapes are determined by equations, so that the rotor is guided at three apexes by the housing contour so that no gearing is required. The devices may be employed in pairs to produce a constant rate of fluid displacement.
