Abstract
An engine includes an engine block containing a spherical compartment with an equatorial zone removed to create an annular gap, a ring member slidably encircling the annular gap having an outer surface and having an opening to permit the passage of combustion gases which periodically aligns with a port in the engine block, a hinge pin mounted within the ring member and extending through the center point of the sphere, first and second divider members, each having a connecting end and a free end, the connecting end of which includes a tube section which surrounds the hinge pin, and the free end of which is directed toward, abuts and conforms to the sphere surface which, together, separate the sphere into two combustion chambers having variable volumes, such that as one combustion chamber expands the other combustion chamber correspondingly contacts, a slot in the surface of the free end of each divider member extending parallel to the longitudinal axis of the hinge pin, a fulcrum member projecting from the sphere into each slot to guide the divider members, an ignition mechanism mounted in the sphere to ignite a fuel air mixture within the sphere alternately on either side of the dividing members.
