Abstract:
A rotary piston mechanism for internal combustion engines, fluid motors, pumps and the like has an outer body enclosing a chamber that is defined by three equal curvilinear walls that circumscribe the chamber axis and define an equilateral triangle in a plane perpendicular to the chamber axis, the walls being convex with respect to the axis, and a generally elongated rotor confined in the chamber of length equal to the span of the chamber along a bisector of any of the angles of the equilateral triangle defined by the chamber walls, the rotor being pivotally supported to rotate about a rotor axis which is parallel to the chamber axis and moves around the chamber axis over a closed path, the sense of rotation of the rotor on the rotor axis being opposite to the sense of rotation of the rotor axis around the chamber axis.
