<p>A toroidal piston engine has a pair of impact rings that transfer kinetic energy between rotors, and are modified to reduce stresses during collisions. Generally, each impact ring has a pad, and is coupled to a rotor such that when a rotor rotates, the pad of one impact ring strikes the pad of another impact ring, transferring kinetic energy between the rotors, while preventing pistons coupled to the rotors from striking one another directly.</p> |
