ABSTRACT:
A four stroke, internal combustion, rotary engine which completes a four stroke cycle in one revolution is described. The engine consists of a wedge shaped combustion chamber having a pivotal wall, and intake and exhaust valves, together with a spark plug or injector for diesel operation. Abutting the combustion chamber pivotal wall is a circular chamber having a rotor therein with two opposed vertices. The vertices mount rollers which engage the walls of the circular chamber. The rotor is displaced by the pivotal wall moving downwardly during the combustion phase to open an exhaust port in the circular chamber. Continued rotation of the rotor then displaces the pivotal wall upwardly to exhaust the combustion chamber, so that the chamber may intake, displacing the pivotal wall downwardly. Continued rotation then displaces the pivotal wall upwardly to compress the fuel mixture for combustion, completing the cycle.
