OSTI ID:6823964
This patent describes a double-rotor engine. It comprises: a base; a housing rotatably mounted to the base and forming a radial cylinder; an output shaft rotatably mounted concentric with the housing and having an arm rigidly extending therefrom within the housing; a piston slidingly engaging the cylinder and forming a combustion chamber with the cylinder; means for admitting a fuel-air mixture into the cylinder; means for releasing combustion products from the cylinder following operation of the expanding means; turbine means operatively connected between the base and the housing, the turbine means providing a torque reaction against the housing in response to flow of the combustion products from the releasing means; and stop means on the shaft for limiting the relative movement between the shaft and the housing.
