The invention relates to a rotary internal combustion engine. More specifically, the invention relates to a coaxial stator (1) and rotor (7). The stator (1) is provided with an inlet nozzle (19) and an exhaust nozzle (20) while the rotor is provided with radial mobile blades (9) which are disposed in grooves (8) with room to move. According to the invention, the inner tips of the aforementioned blades (9) are provided with shafts (15) and a pair of connecting rods (16) is articulated to each of said shafts (15). In this way, at each of the ends of the engine, four connecting rods (16) form a deformable parallelogram which connects four alternating blades (9), while another four connecting rods form a second parallelogram which connects the other four blades. As a result, a mechanical transmission system is created between the blades (9) which ensures that the retraction movements of any of said blades are transmitted to the remaining blades of the group, so that the segments (11) disposed at the free edge thereof are permanently in contact with the inner surface (19) of the stator (1), thereby ensuring that the chambers (18) defined by the blades between the stator (1) and the rotor (7) are perfectly sealed.
An explosion or internal combustion rotary engine, of the type structured by means of a cylindrical rotor with radial housings for a plurality of blades defining chambers in a tubular stator, of generally cylindrical inner configuration, which is closed by means of end covers, characterized in that the stator (1) includes an inner wall (17) of elliptical section, while the rotor (7) includes eight radial blades (9) properly interrelated such that the retraction movement of part of them is combined with the ejection movement of the others in order for the mechanical relationship existing between them to determine that the same are kept in permanent contact with the inner wall (17) of the stator (1).
An explosion or internal combustion rotary engine according to previous claims, characterized in that each blade (9) includes its recessed outer edge (10), configuring a groove as a channel in which a segment (11) is coupled with freedom of movement, which constitutes a bridge of union between the blade (9) and the wall (17) of the stator (1) and which adopts a configuration as an approximately cylindrical segment, each segment (11) overlapping on its ends another two segments (11′) coupled in rectangular channels (12) of the ends of the blade (9).
An explosion or internal combustion rotary engine according to previous claims, characterized in that said articulated connecting rods (16) are located in a pair of chambers established between the ends of rotor (7) and the covers (2) closing the tubular body (1) constituting the stator.
An explosion or internal combustion rotary engine according to previous claims, characterized in that its covers (2) each include, at the level of the housing (22) of the stator for the spark plug, small recesses (23) communicating the chambers adjacent to each blade (9) when the latter passes by the spark plug.
