Abstract
A rotary engine comprised of a pair of counterrotating rotors within a non-rotating outer housing. Each of the rotors is coupled to a common power shaft, one directly and the other through a reversing gear arrangement. Both are driven by the hyper-expansion of combustion gases in a repeating combustion cycle. Each has a generally circular, nearly frictionless working surface perpendicular to the power shaft axis. Each rotor surface defines chambers which rotate past each other. Within such chambers, compressed air and fuel are introduced, mixed, ignited, allowed to hyper-expand (and thus cause the rotation) and exhausted. The power shaft may be connected to a conventional clutch, torque converter, gearbox, differential, alternator or a similar system.
Claims32
A rotary engine comprising counterrotating primary and secondary rotors, each rotor perpendicularly coupled to a power shaft defining a rotation axis, each rotor and the power shaft being free to rotate about the rotation axis;
- in which the primary rotor is directly coupled to the power shaft and the secondary rotor is coupled to the power shaft through a reversing gear arrangement, in which the primary and secondary rotors together define in the vicinity of their outer, facing peripheral surfaces a set of circumferential tongues and grooves that lie around the outermost extent of the perimeters of each of the primary and secondary rotors, and interlace with each other when the rotors are assembled with their respective inner surfaces facing each other, and provide controlled flow of gases into or from between the primary and secondary rotors.
A rotary internal combustion engine comprising counterrotating primary and secondary rotors, each rotor perpendicularly coupled to a power shaft defining a rotation axis, each rotor and the power shaft being free to rotate about the rotation axis;
- in which the primary rotor is directly coupled to the power shaft and the secondary rotor is coupled to the power shaft through a reversing gear arrangement;
- and further in which the primary and secondary rotors comprise circumferential interlaced tongues and grooves having overlapping gaps which define at least one port for the flow of gases into or out of recesses formed in inner facing surfaces of the primary and secondary rotors.
