<p>The engine has a rotor housing (1) with a circular cross section, in which two pair of pistons (5-8) run in a rotation movement. A gear (14) has a non-circular hollow wheels (3, 4) arranged in an inner side of a moving path of the pistons, where the wheels exhibit a main axis and secondary axis. The hollow wheels are connected with the pair of pistons in a fixed manner. An inner wall of the rotor housing is curved in a toroid shape, and the hollow wheels exhibits convex sections in the area of auxiliary vertices, which are provided as end points of the secondary axis.</p> |
