ABSTRACT:
The engine comprises a spherical chamber within which moves a dual piston mounted to rotate reciprocatingly about a shaft going through the center of said chamber, the chamber being closed by a cylinder head. Said piston is basically shaped as a semicircular vane and is attached to a cylindrical shaft. It extends orthogonally along the shaft's generatrices. Said piston has a slightly smaller radius than the spherical chamber so that it moves about near the inside wall of said chamber. Sealing is provided between the piston and the chamber in the form of at least one sealing strip embedded in a groove in the periphery of the piston. The cylinder head extends across the diameter of the chamber and has, on at least one of the sides of the shaft and near thereto, an edge extending parallel to said shaft's generatrices. Sealing is provided between said shaft and said cylinder head in the form of at least one sealing insert embedded in a groove in the length of said edge.
