US Patent 12116925 Rotary engine with dual axis rotor rotation

A rotary engine with dual axis rotor rotation that includes a stator housing, two rotors within a combustion chamber, an output shaft with drive gears coupled thereto, and two planetary shafts parallel and flanking the output shaft, wherein the planetary shafts each include two freely rotatable planetary gears coupled, respectively, to each rotor and two sets of rotor drive gears of different radiuses that are operably coupled to the drive gears of the output shaft, wherein, during the completely combustion cycle the gear configurations and positions enable the first and second rotors to follow a dual axis, eccentric, counterclockwise, and out-of-phase rotation.
