Title: High-output robust rotary engine with a symmetrical drive and improved combustion efficiency having a low manufacturing cost

Abstract: An oscillatory scissor type rotary engine having two rotors wherein first and second rotor drive mechanisms are located on first and second opposite sides of the engine respectively, each rotor drive mechanisms including a carrier bowl that is rigidly fixed to an output shaft passing through the two hollow rotor drive shafts and mounted in bearings thus obviating the need for a separate drive mechanism support structure. By evenly spreading the load between all meshed gears through the provision of shock-absorbent members in the connecting rod heads, and of an increased number of symmetrically positioned planetary crank-and-pinion units on each side of the engine, and by evening out the impact loading through the use of drive components as flywheels, the resultant design is made simple, reliable, durable and dynamically balanced. The unique co-axial shaft arrangement ensuring precise rotor positioning enables elimination of conventional mechanical sealing and instead provides dynamic sealing of gases, to improve the durability of engine components. These dynamic gaps additionally accommodate heat-insulating coatings in the gaps between the housing and vanes and on the vanes themselves, which in turn result in reduced heat loads on major engine components, enabling the elimination of substantial housing cooling requirements. This advantage can permit housing/component cooling solely by means of circulating oil lubricant in cooling conduits in the housing and vanes, without the need for additional water cooling equipment, thereby to save manufacturing costs.
