Abstract
A piston rotor and a chamber partitioning rotor are continuously rotated unidirectionally about fixed rotational axes intersecting at an acute angle within a spherical chamber enclosed by a housing. Simultaneous rotation of the rotors and relative angular movement therebetween occurs because of a pivotal joint interconnecting such rotors at the intersection of the rotational axes coinciding with the geometric center of the spherical chamber. Pressure cavities formed between the rotors within the spherical chamber are volumetrically varied in response to the relative movement of the rotors. For internal combustion engine operation, port controlling dome segments within the chamber are rotated at a reduction drive ratio to the chamber partitioning rotor through planetary gearing.
