Abstract
A rotary engine is provided for providing torque. The engine includes a housing, a stator, a crank shaft, a rotor and a pair of vanes. The housing has an inner wall with an elliptical profile with major and minor axes. The stator has an outer wall and a double ellipsoid profile corresponding to the major and minor axes. The crank shaft is disposed at a junction of the major and minor axes, rotating about a spin axis orthogonal to the profiles. The rotor has an annular circular profile disposed between the inner and outer walls. The rotor turns on the crank shaft. The vanes radially slide within the rotor as the crank shaft rotates and as the vanes turn within the inner and outer walls.
