ABSTRACT:
A rotary internal combustion engine, including all types of vehicles and equipments or apparatus provided with such rotary engines, or machines which principally consist of a two, three or four, either radially curved or flat, apex rotor and a radially arcaded or curved epicyclic or two or three lobed epitrochoid housing cavity, in which construction such rotary engine, the rotor (21 of FIG. 1), has its rotations integrated with the rotations of the main crankshaft (24 of FIG. 1), through the intermeshing gears train (37, 38, 37, 48, 51, 52 of FIG. 1) or through the planetary gears system or epicyclic gears train (324, 348, 459, 360, 361, 362 of FIGS. 5 and 6 and 362/I, 362/II of FIGS. 9 and 10) by which rotor will be rotated or rotates in accordance to its specific basic speed ratio (such as 1:2 for bi-apex rotor, 1:3 for tri-apex rotor, etc.) so thereafter the rotor will rotate with an effective clearance during all relative rotations and therefore is able to maintain such permanent distance between the cooperating shapes of the stationary outer components or the housing and the rotating inner component or the rotor, which distance will be used for inserting proper sealing elements, which because of its radially curved geometrical nature, it is therefore able to seal the working chambers precisely and eliminate any of the so called corner seal leakages which commonly occur in the conventional models, beside also being able to avoid any possibility of direct contact between the rotor apex portions and the inner housing cavity wall.
