  • Patent number: 4033299
    Abstract: This rotary engine performs the same four phases as any other piston and rotary engine. Yet, unlike other engines this one has no crankshaft. It consists of a circular housing in which a circular rotor revolves slightly off center in relation to its housing.The rotor carries through its cavity vanes (or blades) that are kept continuously close to the housing by the centrifugal force as the rotor turns. The vanes never touch the housing, they are kept at a safe distance by a ring which is guided by a ball bearing. To make the contact gas-tight each vane is tipped with an inset metal strip.The rotor with its vanes rotating in its housing develops two expanding-contracting chambers, one inside it and the other peripheral to the housing.The inside chamber is to intake the mixture and pump it into the peripheral or combustion chamber, this will decrease in volume compressing the mixture, as the rotor edges by the spark plug the fuel-air mixture is ignited, the exploding gas pushes the rotor in its circular motion.
