Abstract:
An axial-piston engine comprising a centrally located output shaft (1) and a plurality of piston-cylinder units (2) oriented parallel to and grouped symmetrically about said output shaft (1), a thrust yoke (5) mounted on said output shaft (1) so as to rotate therewith, said thrust yoke providing support to an tilted cam plate (4) mounted on bearings in a freely rotating manner on the perimeter of said thrust yoke (5), means (6, 7) for preventing the rotation of said tilted cam plate (4) with respect to the body of the engine, and ball-jointed piston rods (9) connecting each piston (12) of the engine to said tilted cam plate (4) so as to transmit the sequential thrust of said pistons (12) to said tilted cam plate (4) thus effecting a rotational motion of said output shaft (1), characterized in that the skirt of each piston (12) is provided with vanes (14) on which a force is exerted owing to an air vortex generated in the crankcase (3, 3') by the nutating movement of the tilted cam plate (4) every time the skirt of the piston (12) travels outward from the bore of the cylinder (2), thus exerting a certain degree of axial rotation of the piston (12).
