Rotary engine with axially directly connected compression and power cylinders

A rotary engine with axially directly connected compression and power cylinders, comprising a compression cylinder and a power cylinder;

• the compression cylinder being internally provided with a compression rotor having three blades, the power cylinder being internally provided with a power rotor having three blades, and the compression rotor and the power rotor rotating coaxially;
• characterized in that
• the rotary engine further comprises an intermediate cylinder wall and a combustion chamber unit;
• the intermediate cylinder wall being located between the compression cylinder and the power cylinder to serve as a common inner-end wall of the compression cylinder and the power cylinder, and having a first circular recess and a second circular recess formed at two opposite end surfaces thereof;
• the first circular recess communicating with the compression cylinder and being sized for fitly receiving a compression-side rotational valve that rotates synchronously with the compression rotor, and the second circular recess communicating with the power cylinder and being sized for fitly receiving a power-side rotational valve that rotates synchronously with the power rotor;
• the compression-side rotational valve being provided with three L-shaped first openings, which are located corresponding to the three blades of the compression rotor and respectively have an outlet located on a circumferential wall of the compression-side rotational valve, and the power-side rotational valve being provided with three L-shaped second openings, which are located corresponding to the three blades of the power rotor and respectively have an outlet located on a circumferential wall of the power-side rotational valve;
• the intermediate cylinder wall being provided on a circumferential surface with a first through hole and a second through hole;
• the first through hole being located within a rotational orbit of the outlets of the first openings, and the second through hole being located within a rotational orbit of the outlets of the second openings;
• and
• the combustion chamber unit internally defining a hollow combustion chamber and being fixedly connected to the circumferential surface of the intermediate cylinder wall;
• the combustion chamber communicating with the first through hole and the second through hole, such that compressed air-fuel mixture in the compression cylinder can sequentially flow through two aligned L-shaped first opening and first through hole into the combustion chamber and high temperature high pressure gas in the combustion chamber can sequentially flow through two aligned second through hole and L-shaped second opening into the power cylinder.
