Abstract:
An engine with counter-rotating housing and output shaft, comprising the following combination of components:(a) an elongated stationary spindle rigidly attached to a support structure; (b) a hollow output shaft extending through a length of the engine and journaled about said spindle for concentric rotation around the spindle; (c) a housing journaled about said output shaft for concentric counter-rotation around the shaft; and (d) means for producing said concentric rotation and counter-rotation as a result of a process of energy conversion; whereby during operation of the engine an inertial balance is established between said output shaft and said housing by rotating in opposite directions concentrically with respect to said stationary spindle; wherein said engine is a rotary-piston engine and said process of energy conversion includes combustion of a fuel in a combustion chamber.
