Rotary engine
In a rotary internal combustion engine of the type including a housing having a generally continuous inner circumferential surface, and a pair of opposed inwardly extending side walls, a rotor rotatably mounted within the housing and having an external generally peripheral surface in close proximity to the inner circumferential surface of the housing and side edge surfaces adjacent the side walls, at least one power producing pocket in the outer peripheral surface of the rotor and extending thereacross, the pocket is defined in the direction of rotation of the rotor by a steep shoulder extending inwardly from the outer peripheral surface and a gradual sloping section returning to the outer peripheral surface and merging therewith. The improvement described comprises an oscillating means mounted in an opening in the inner circumferential surface of the housing. The oscillating means include a movable member having the width of the rotor and having a rotor engaging inner surface. The movable member has an outwardly open cavity formed therein and receiving a stationary piston member, the movable member and piston member defining an expandable combustion chamber within the member, the combustion chamber having an inlet valve for the admission of a pressurized combustible gas, an ignition means, and outlet means for communicating combustion gases developed in the combustion chamber into the power pocket to thereby produce a force between the oscillating means and the shoulder for driving the rotor.
