Zusammenfassung:The invention relates to a rotary combustion engine comprising a driving eccentric ring (11) arranged between a non-rotary outer casing (1) and a non - rotary inner casing (3) for rotating a power shaft (5) situated inside the inner casing. In order to drive the eccentric ring, a combustion chamber arrangement (14, 15) is provided between the inner and the outer casing for burning a mixture of fuel and air supplied thereto, the power shaft (5) bein g provided with an eccentric element (8). In order to minimize the number of rotating components, a second eccentric ring (12) is mounted by means of a bearing (9) around the power shaft (5) inside the aforementioned inner casin g (3), this second ring being coaxial with and fixed to the driving eccentric ring (11), and the eccentric ring arrangement (11, 12) being a substantially non-rotary unit that only performs an eccentric motion, which makes the powe r shaft (5) rotate.
