  • This invention relates to rotary blade piston engines and more particularly to an internal combustion engine and its operating process in which a plurality of suitably proled blade pistons are mounted individually and independently from each other freely movable on an excentric segment of an excentric shaft which is disposed centrally of a rotor wherein the pistons operate in an elliptical path during their revolutions.
  • FIGURE 1 is an end view of the rotary engine, partly in section,
  • FIGURE 2 is a longitudinal axial View of the rotary engine of FIGURE l, partly in section.
  • FIGURE l it will be seen that in the rotor 1 a plurality of blade pistons 3, 4, 5, and 6 are individually and independently mounted in a radially extending manner for rotation on excentric segments 7, 8, 9, respectively of an excentrc shaft 1l mounted axially in the center of the rotor.
  • the excentric shaft 11 has the necessary number of excentric segments to accommodate the blade pistons.
  • the excentric segments are disposed in a suitable manner axially adjacent each other and arranged radially at equal intervals from each other and are appropriately displaced along their path of travel so that the pistons may rotate freely inside the rotor around the excentric segments of the excentric shaft.
  • the pistons are coupled individually in a suitable manner by means of segmental circular bearing cups or slotted pivot bolts Z at equal intervals from each other in circular bearing openings 47 of the rotor ring segments 58 so as to be positively and movably coupled therewith in order that the segmental -circular bearing cups or pivot bolts with the blade pistons mounted therein may carry out a free pivoting movement, and that the pistons may execute a radial sliding movement therein.
  • the excentric shaft has the effect of positively guiding all the blade pistons and rotates in the opposite direction of the rotor with the same number of revolutions.
  • the excentric shaft 11 is mounted appropriately axially and centrally inside the rotor and is passed through the hollow rotor shaft 45 outwardly and is controlled by means of gears 37 and 38 from the loutside in a suitable manner.
