A modular revolving engine with tangential explosions, comprising;
- at least one intake flywheel (Va) and a motive flywheel (Vm) that are aligned in laterally opposing relationship, a slide-free drive system (1) which makes the at least one intake flywheel and the motive flywheel rotatably interdependent by causing them to rotate in opposite directions with respect to each other in a common plane that is perpendicular to their respective rotational axes, groups of components for the recovery of power from the explosions distributed at equal intervals along a periphery of each flywheel, each group of components including a hollow pushrod (7, 7b) reciprocally mounted within a hollow pushrod support (5) so that an inner portion of each pushrod communicates with a separate one of a plurality of combustions chambers (4) formed within each flywheel, each pushrod including an exhaust duct having a discharge opening oriented outwardly of the corresponding flywheel, each pushrod being positioned so that an elongated central axis thereof is parallel to a line passing through a line passing through a center of each flywheel and spaced at a distance (30) therefrom that is the same for all the groups of components, each group of components further including a compression spring (6) mounted on each flywheel so as to urge the pushrod of the corresponding group of components toward an outermost position thereof within the corresponding pushrod support so that outer portions of the pushrods carried by one of the flywheels engage with outer portions of aligned pushrods of the other opposing of the flywheels during each rotation of the opposing flywheels and such that during the engagement of the corresponding and aligned pushrods, the pushrods are driven in a linear stroke to their innermost positions within their pushrod supports, means for limiting the linear stroke of each pushrod, means for preventing rotation of each pushrod about a longitudinal axis thereof, means for limiting a centrifugal force to which each pushrod is subjected during the rotation of the flywheels, an ignition system within each combustion chamber, the at least one intake flywheel rotating freely on a hollow shaft (9) that includes an intake slot (2) that successively aligns with chamber slots (3) associated with each combustion chamber (4), and one of each of the opposing flywheels including pushrods (7) having ball-like outer end portions that are cooperatively seated within half-shell outer end portions (7B) of the pushrods (7B) of the opposing flywheel.
