| 摘要 |
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) being 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 casing (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 power shaft (5) rotate.
