A bearing seat 18 is arranged on the outer side of the sealing end of the stator 1, the central shaft 10 penetrates through a bearing in the bearing seat 18 to ensure that the stator 1 and the rotor 2 move concentrically and fix the geometric relationship of the two parts, and the central shaft 10 is fixed on the rotor 2 through a shaft head nut 19.

The outer wall of the opening end of the rotor 2 is provided with a second tesla valve channel 11 which extends to the sealing end of the rotor 2 through the outer side wall of the rotor 2, the first tesla valve channel 3 and the second tesla valve channel 11 are of the same half tesla valve structure but are arranged in opposite circumferential directions, one is in a clockwise direction, and the other is in a counterclockwise direction. The rotation direction of the rotor 2 during working depends on the direction interchange of the tesla valve structures of the stator 1 and the rotor 2 (the direction of the tesla valve refers to that when fluid moves in the tesla valve, the direction with small resistance is forward, the direction with large resistance is reverse, and the period of the tesla valve is the minimum structure size of the same geometrical structure repeated. After the stator 1 and the rotor 2 are mounted together, a rotational gap of 0.2-0.5mm is left between the two in the relative rotational section.

The circumferential direction of the tesla-structure groove coincides with the rotational direction of the rotor 2, so that the tesla valve ring 14 functions as an intake check valve. When the rotor 2 rotates, the turbine blades 24 on the rotor 2 guide the air-fuel mixture through the air inlet opening into the tesla valve ring 14 and finally into the combustion chamber 4 on the stator 1.

The sealing end of the stator 1 is provided with heat dissipation holes 25 which are circumferentially arranged, so that heat dissipation during working is facilitated.

As an internal combustion engine, the external attachment of the present invention further includes: starting a motor and a storage battery, a spark plug 6 ignition control device and the like. These devices are not essential to the use of conventional internal combustion engines and are not in the subject of the present patent, and are therefore not listed and discussed. In discussing the principles of operation of the present invention, however, it has been assumed that the devices described above are present and operating properly. If necessary, the device of the invention also considers the water-cooling pump and the heat exchanger thereof.

The invention relates to the working principle.

The turbine blades 24 are driven by the external starter to start circular motion with the rotor 2. This process also presses the mixture in the turbine cover 12 through the passages of the tesla valve ring 14 into the combustion chamber 4 of the stator 1 and continuously sucks the mixture from the outside through the central inlet 13 of the turbine cover 12.

When the oil-gas mixture reaches the combustion chamber 4, the spark plug 6 can discharge and ignite at a proper moment, and the gas is deflagrated to form high-pressure gas. Due to the one-way conduction function of the tesla valve ring 14, the high-pressure gas cannot flow back from the gas inlet and can only flow along the circumferential direction between the stator 1 and the rotor 2 through the tesla valve channels reserved on the stator 1 and the rotor 2.

As shown in fig. 11, after a tesla valve strip is divided into two parts, one of the two parts is turned 180 ° and replaced again, a new tesla valve with opposite directions is formed, i.e. the new tesla valve is formed by the first tesla valve channel 3 and the second tesla valve channel 11. In this new tesla valve, the upper and lower halves oppose each other in resistance to flow through the tesla valve.

In the vicinity of the combustion chamber 4, the flowing gas is not directional. However, because the stator 1 and the rotor 2 are of the novel tesla valve structure with opposite directions on both sides of the rotating gap (in the figure, the stator 1 is counterclockwise, and the rotor 2 is clockwise), the stator 1 can provide counterclockwise resistance to the airflow in the airflow flowing process, so that the airflow flows slowly along the clockwise direction, and even stops completely. Similarly, a counter-clockwise moving air stream will encounter a clockwise resistance on the rotor 2. However, since the rotor 2 can make a circular motion relative to the combustion chamber 4, the resistance exerted on the air flow by the rotor 2 becomes a moment that the air flow pushes the rotor 2 to rotate, and the rotor 2 is forced to make a counterclockwise rotation. Once the rotor 2 has been brought into a counter-clockwise rotation, all the air flow against the direction of rotation of the rotor 2 is almost equivalent to no resistance (viscous resistance) with respect to the rotation of the rotor 2. While all the counter-clockwise rotating gas flow lines can also have little resistance for the stator 1. The end result is that the exploding high pressure gas acts on the tesla valve passages of the stator 1 and rotor 2, respectively, creating a torque which forces the rotor 2 to rotate relative to the stator 1, i.e. as shown, the stator 1 (upper half) is subjected to a right force F1 and the rotor 2 (lower half) is subjected to a left force F2, which forces the upper and lower parts to move relative to each other, depending on the unidirectional conductance nature of the tesla valve. If this structure is distributed over a 360 deg. circumference, a relative rotational movement is generated.

In fact, the air flow moving against the direction of the rotor 2 also forms a great resistance to movement due to the viscous effect of the surface of the rotor 2 on the air flow. In the small circumferential direction from the combustion chamber 4 to the exhaust port 7, the combined force of the airflow obstruction of the reverse tesla valve on the stator 1 and the high-speed viscous action of the rotor 2 forces the airflow to hardly reach the exhaust port 7 in the clockwise direction, and the distance is 6-8 times the periodic arrangement of the single tesla valve bodies. Thus, 80% of the high-pressure gas exploded in all the combustion chambers 4 reaches the exhaust port 7 from the large circumferential direction counterclockwise (in the direction synchronized with the rotor 2), and the maximum thermal efficiency is satisfied.

It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the invention.
