Abstract of the Disclosure. The invention provides for an internal combustion engine that causes a radial flow of combustible gases about the axis of a torroid or annulus cylinder. The cylinder will have an intake and exhaust port, together with provision for a spark plug and/or fuel injector. The cylinder encloses four pistons. Two pistons are connected diametrically opposite to each other to a forward driving disc. The two remaining pistons are similarly connected to a rear driving disc. Provision is also made within the cylinder wall for the intrusion of the forward and rear driving discs. The discs are respectively connected to an inner and outer driving shaft that are independently rotatable about the axis of the cylinder. The coaxial shafts thus described pass along the axis of the cylinder to a rhomboid and power take off unit. Within this unit radial arms connected to the inner and outer shafts are pinned centrally to the links of a rhomboid mechanism. The four links of the rhomboid mechanism have rollers at their pinned ends and these rollers are caused to follow the contour of a stationary can within which the rhomboid mechanism is contained. A rotational displacement about the axis of the engine of the rhomboid mechanism leads to an angular displacement of the links. This displacement is translated to the inner and outer driving shafts and hence by firm connection to the pistons. The cam being of the desired contour, causes the pistons to move with a compound motion within the cylinder whereby any pair of adjacent pistons not only rotate about the axis of the cylinder but also move with an angular harmonic motion with respect to each other. Thus there exists within the cylinder, separated by the pistons, four variable cavities. These spaces or cavities -1- which in turn increase whilst exposed to the intake port, decrease for a compression of gas, increase for the expansion of hot gas, and decrease whilst exposed to an exhaust port, causing the equivalent of four power strokes per revolution of the engine. Unlike a number of proposed rotary engines, the power from this engine is not taken directly from the inner or outer shaft, but from the rhomboid mechanism to a power take-off coupling and a separate final drive shaft. -2-
