ABSTRACT:
A rotary combustion engine includes a driving eccentric ring arranged between a non-rotary outer casing and a non-rotary inner casing for rotating a power shaft situated inside the inner casing. In order to drive the eccentric ring, a combustion chamber arrangement is provided between the inner and the outer non-rotary casings for burning a mixture of fuel and air supplied thereto, the power shaft being provided with an eccentric element. In order to minimize the number of rotating components, a second eccentric ring is mounted by a bearing around the power shaft inside the aforementioned non-rotary inner casing, this second ring being coaxial with and fixed to the driving eccentric ring, and the eccentric ring arrangement being a substantially non-rotary unit that only performs an eccentric motion, which makes the power shaft rotate.
