Abstract

PURPOSE:To increase the compression ratio and to transmit the rotation smoothly without using a crank shaft by providing a pair of fan-shaped preceding and succeeding rotors in a cylindrical case so that a combustion chamber enclosed between both rotors is made minimum at compression and discharge strokes. CONSTITUTION:If a combustion chamber 7 is at a suction stroke when an engine is started, the small diameter portion of a gear 17 is engaged with the large diameter portion of a gear 20 and a rotary shaft 3 is rotated faster than a rotary shaft 5, thereby a preceding rotor 4 is moved faster than a succeeding rotor 6, the chamber 7 is expanded and the fuel is sucked through a suction port 13, and when the capacity of the chamber 7 is made maximum, a hole 13 is blocked by the outer peripheral surface of the rotor 6 and the suction stroke is completed. Next, the large diameter portion of the gear 17 is engaged with the small diameter portion of the gear 20, the rotary shaft 5 is rotated faster than the rotary shaft 3 and the rotor 4 is moved slower than the rotor 6, thereby the capacity of the chamber 7 is made small and the fuel is compressed, thus the compression action immediately in front of an ignition plug 15 is made greatest, and the plug 15 is ignited to explode. As a result of this expansion, the chamber 7 is again expanded, the gear 17 is engaged with the gear 20, the shaft 3 is rotated faster than the shaft 5, and the chamber is shrinked to discharge through a discharge port 14.

Description

[Detailed description of the invention] This invention relates to a rotary engine.

Conventional rotary engines, such as the Wankel type rotary engine, have a structure in which rounded triangular (9) rolling stones are housed within a cocoon-shaped casing, making it possible to increase or change the compression ratio. However, since the transmission of the rolling motion to the output shaft is done through the crankshaft, there is the drawback that the transmission is not smooth.

This invention eliminates the drawbacks of the above-mentioned conventional products, increases the compression ratio, and enables smooth transmission of (b) rotational motion to the output shaft without using a crankshaft. The purpose is to provide a rotary engine that is simple and easy to manufacture.

The present invention will be described with reference to embodiments shown in the drawings.

In Figs. 1 to 3, l is a cylindrical casing with a front number ζ attached to one end of a bearing member 8, and inside this casing 1 there is an inner rotating shaft 8 which is coaxially arranged in the center of the casing. A pair of rotors fixed symmetrically to 4. A and a pair of rotors 6.11', which are similarly fixed symmetrically on the outer rotation axis S, are arranged to be rotatable.

These rotors4. A and 6. The outer peripheral surface and the front direction of l are in contact with the inner wall of the casing 1 by 3 m, and both end directions are 1 turn @3.
It is formed into a roughly cylindrical shape with a corner 1#L8 extending 60 degrees from the center of the vessel. and C's O-t 4.4' and 6,
4 combustion types by both 6' sai+ and the inner wall of casing l? , 8,9°10 are formed. A lid 12 having a bearing portion 11 for supporting the shaft end of the rotating shaft 3 is mounted on the front surface of the casing 1 to seal the inside of the casing.

Further, in the upper circumferential wall of the casing 1, an inlet hole 13 and an exhaust hole 14, which are approximately the same size as the outer circumferential surface of the rotor and have a symmetrical shape, are sequentially bored in the direction of rotation. Fuel such as gas is supplied through a supply pipe (not shown). Suction hole 13 and exhaust hole 1
An ignition plug (#11 in Fig. 4) is installed on the peripheral wall of the casing l at the intermediate position of 4. ◇On the rotating shaft a, 5 protruding outward from the casing l through the bearing member 2, Elliptical units 16 and 17 of the same shape are arranged separately with a phase shift of 90 in mutually orthogonal directions,
The rotary shaft 3 is faster than the single rotor during the suction process and the explosion of the rotor, and the rotary shaft is faster than the rotary shaft 3 during the compression process and exhaust.

An output shaft 18 is supported at the other end of the bearing member 8, and the gear 1g is mounted on this output shaft.

Ellipse with the same shape as 17 - single G,! Similarly, the small diameter portion of the gear 19 and the large diameter portion of the shaft wheel 16 are integrally arranged so that the large diameter portion of the gear 20 and the small diameter portion of the gear 17 mesh with each other. There is.

Next, the operation of the previous two embodiments will be explained with reference to Fig. 4 (-) to (f+). The figure shows the positional relationship, and the left side is the gear 16.1 fixed to the rotating shaft 3.s.

．． It is 20. For convenience of explanation, the combustion chamber 7 formed by the opposing end surfaces of the a-tube 4 and the rotor 6, and the inner wall of the casing will be mainly explained.

First, a gear 8 (not shown) fixedly installed on the output shaft 18 is rotated via a drive mechanism, and this rotational force is sequentially applied to the gears 1G, 1G, and 16.17. Rotors 4, 4' on a and rotor 'e#'&- rotate in the direction of the arrow to start. This allows for example 7 combustion chambers or 4 intake manifolds! (
In the case shown in Fig. 4 1), the small diameter part of gear 17 is
(2) Since the N rotating shaft 3 can rotate faster than the rotating shaft 5 (2), the leading rotor 4 moves faster than the somatic rotor 6 and gradually expands the combustion chamber 7. Then, fuel continues to be sucked from the suction hole 13.

This suction continues until the leading end surface of the leading rotor 4 approaches the ignition Zolag 1s, and Shin Uchitani in the combustion chamber 7 reaches R
At #, the suction hole 18 is closed by the outer peripheral surface of the forward rotor 6, thereby completing the suction process and sealing the combustion chamber 7 (FIG. 4b).

Thereafter, the large diameter part of the gear 17 meshes with the diameter part of the spacer 200)tJ-, and contrary to the above, the rotation IMs can rotate faster than the rotation shaft 3, so that the leading rotor 4 is rotated by the trailing rotor 6. Move slower. Therefore, the internal volume of combustion M7 gradually decreases, and the fuel inside is compressed. This compression effect is maximum when the rear end surface of the preceding rotor 4 slightly exceeds the spark plug 18JE and the front end surface of the conventional rotor 6 is positioned slightly in front of the spark plug (FIG. 4).

Next, the spark plug IB is energized to ignite and burn the compressed fuel in the combustion chamber γ, which has been brought into a high-temperature and high-pressure state.

This is an explosion, and the combustion chamber 7 is expanded again due to the expansion caused by this explosion (Fig. 4). When this expansion starts, the small diameter part of the gear 17 meshes with the large diameter part of the gear 30, and the single rotation shaft 3 can rotate faster than the rotation @S, so the leading rotor 4 is faster than the trailing rotor 6. also moves fast,
When the leading rotor 4 reaches the position where it roars through the exhaust hole 14 *([
4 Figure 1) *@It becomes the size of an umbrella. Thereafter, as described above, the trailing rotor moves faster than the leading rotor 4 to make the combustion chamber 1 smaller, and the exhaust hole 14 is opened by the movement of the leading rotor 4, so that combustion gas is discharged from the exhaust hole 14. is evacuated and after evacuation, the rotor 4°6 returns to its original state II (1
14 Returning to Figure 1), it becomes ζ2 which rotates 1@.

As mentioned above, the combustion is caused by the rotation of gears II and 17.
Li? performs suction, compression, explosion, and exhaust operations, and performs the same internal combustion engine action as a 4-stroke cylinder, and at the same time each rotor 4.6. A, one combustion at the C threshold 118,9
．． 10 also has the same effect as Kenpo. By extracting the rotational interlocking of the gears 16 and 17 as described above through the mold wheels is and go, a (b) rotational force is obtained at the output $18, and from then on, this rotational force gives the rotor one rotation of inertia. It functions as a 4-cylinder, 4-cycle engine by repeatedly producing suction, pressure, explosion, and exhaust as described above.

Incidentally, in the above embodiment, two pairs of rotors each consisting of a leading rotor and a trailing rotor are provided in the casing l, but the invention is not limited to this, and it may be one pair, or three or more pairs. There is no point in setting one up. The leading rotor and trailing rotor were made to be of the same size, but either one of the rotors could be made smaller with a narrower width connecting both end surfaces to lower the compression ratio, or conversely, one rotor with a larger width could be It is possible to arbitrarily change the compression ratio by increasing the compression ratio for dust.

Since this invention is constructed as described above, the combustion chamber surrounded between the leading rotor and the trailing rotor of the explosive type can be made the most compact, and therefore the compression ratio can be increased compared to the conventional one. It can be made higher. In addition, it is possible to output one-turn motion without using a rank shaft like in conventional products, and since the output shaft is installed at a location different from the rotor's rotating shaft, transmission of one-turn interlocking to the output shaft is possible. It can be done smoothly with a billion yen. Furthermore, since the rotor moves within the casing in surface contact, it not only has excellent airtightness, but also has excellent effects such as being simple and easy to manufacture.
