In conventional rotary engines, the gas seal of the working chamber is not three-dimensional and the airtightness is poor, and sufficient time is not secured for the intake stroke and exhaust stroke. Furthermore, the structure is complicated and there is room in the dimensions of parts. There was a defect such as not being. The present invention provides a rotary engine as described below to solve the above-mentioned conventional drawbacks. Next, the present invention will be described in detail with reference to the case of the rotary internal combustion engine shown in the drawings. First, as shown in FIGS. 9 and 1, there is a fixed gear 14 at the center, and a bearing 12 is fixed inside the fixed gear 14. It is a side wall of the body with a hole for it. Reference numeral 2 denotes a central wall of the body, which has an intake port 20, an exhaust port 19, and a spark plug mounting port 18, as shown in FIG.
It is a cylindrical one that surrounds the outer rotor 5. Three
Is a horizontal body wall of the same type as 1. There is no fixed gear and the above bearing 1
2 There is a hole for fixing. As shown in FIG. 1, these bodies 1, 2 and 3 are fixed together by bolts and integrally formed to cover a rotor and the like, and are fixed to a vehicle body or the like. Reference numeral 4 denotes a lateral wall of the outer rotor, which forms a part of the working chamber and has a hole for fixing the bearing 8. 5 is an exhaust port 15, an intake port 16 shown in FIG. 2 and FIG. 6 (B). Ignition port 1
7. And the center of the outer rotor with the working chamber wall 25. Reference numeral 6 denotes an outer rotor lateral wall which is of the same type as that of the above-mentioned 4, and these 4.5.6. As shown in FIG. 1, the unit is fixed by bolts and integrally formed to form a working chamber and the like so that the whole unit makes a rotary motion. 7 is inside the working chamber wall 25 of the outer rotor center 5, and as shown in FIG. 1, the inside of the working chamber wall 25 of the outer rotor center 5 is rotatable by the outer rotor lateral walls 4 and 6 and the inner rotor bearing 8. The vane 9 intervenes in the longitudinal direction with the inner rotor fixed to. When the inner rotor 7 rotates, the tip of the vane 9 moves while constantly contacting the working chamber wall 25 of FIG. 2 and reciprocates in the inner rotor 7. Further, since the inner rotor 7 is slightly displaced from the center of the working chamber wall 25, even if the vane 9 moves, the length of the vane 9 to both tips and the working chamber wall 25 at that position.
Since the distance is always the same, the tip of the vane 9 is alternately pushed and reciprocated as the inner rotor 7 rotates. From this, as shown in FIG. 5, when the outer rotor 5 and the inner rotor 7 rotate, the position of D-10 is the suction stroke, A-10 is the compression stroke,
The position of B-10 is the combustion stroke, C-10 is the exhaust stroke, and the main working chamber 10 undergoes volume changes to perform each stroke.
Next, 11 is an output shaft, which is integrally attached to the outer rotors 4 and 6, respectively, and through the outer body bearings 1 and 2 and the outer rotor bearing 12, the outer rotor 4.5.6. The whole is fixed rotatably, and serves as both the rotor shaft and the output shaft. Reference numeral 13 is a revolving gear, which is fixedly attached to one end of the inner rotor 7 and meshes with a fixed gear 14. The fixed gear 14 does not move integrally with the lateral body wall 1. Therefore, when a rotational force is applied to the revolving gear 13, the shaft 23 of the inner rotor pushes the bearing 8 while rotating, so that the outer rotor rotatably rotates through the outer rotor bearing 4.5.6. The entire rotor rotates, while the inner rotors 7 are rotatable within the outer rotors 5 and thus rotate while revolving. At this time, the revolution speed of the revolution gear 13 is twice that of the fixed gear 14. 15
Is the exhaust port of the outer rotor central portion 5 in FIGS. 2 and 6 (B). Reference numeral 16 is an intake port, and 17 is an ignition port, which are rotationally moved. In FIG. 2 and FIG. 7 (b), 18 is a spark plug attachment port of the body central wall 2, 19 is an exhaust port, and 20 is an intake port. Reference numeral 21 denotes a seal, which in FIG. 6 (B) keeps airtightness between the outer rotor center 5 and the body center wall 2 of FIG. 7 and is accommodated in the groove portion of the outer rotor center 5, and FIG. The seal 21 shown in FIG. 2 is housed in the groove of the vane 9 and keeps the main working chamber 10 airtight. Further, the seal 21 in FIG. 6 (A) is the inner rotor 7
And the outer rotors 4 and 6 are kept airtight. Two
Reference numeral 2 denotes an idle working chamber shown in FIG. 2, which does not perform each action such as a suction stroke. Reference numeral 23 denotes shafts at both ends of the inner rotor 7 shown in FIGS. 1 and 6 (A), which are rotatably fixed by bearings 8. Reference numeral 24 denotes a space in which the revolution gear 13 shown in FIGS. 1 and 9 is accommodated, and the gear 13 revolves while rotating in the space. Reference numeral 25 is a curved surface on the wall of the working chamber shown in FIG. From the above, when combustion occurs at B-10 in FIG. 2 first, pressure is applied to the vane 9, so that the inner rotor 7 rotates and is then transmitted to the revolution gear 13 shown in FIG. Thirteen
Is engaged with the fixed gear 14, the revolving gear 13 capable of rotating and revolving revolves while rotating around the fixed gear 14. Therefore, the outer rotor 4.5.6. Is rotatably fixed by the outer rotor bearing 12,
When the inner rotor bearing 8 is pushed, the entire outer rotor is
The rotation and the revolution movement are repeatedly transmitted to the output shaft 11. At this time, the outer rotor 4.5.6. When the gear rotates once, the revolution gear 13 makes two revolutions and further revolves around the fixed gear 14 once. Next, the operation state will be described mainly with reference to FIGS. 2 to 5. First, in A-10 of FIG. 2, the exhaust stroke A-1 is shown at the end of the intake stroke and the compression stroke.
5, the suction port 16 and the ignition port 17 are all closed. B-
10, the compression stroke ends, the spark of the plug of the ignition plug attachment port 18 is transmitted to the ignition port B-17, and the combustion process starts in the working chamber B-10. At this time, the exhaust port B-15, Suction port B-16, closed, ignition port B
-17 is an open state. C-10 is a place where the exhaust stroke is about to start at the end of the combustion stroke, and the exhaust port C-15
Is still closed at this point, and the suction port C-16 and the ignition port C-17 are closed. D-10 is the end of the exhaust stroke and the start of the intake stroke. Exhaust port D-15 is already closed, intake port D-16 is beginning to open, ignition port D-15
-17 is in a closed state. In Fig. 3, the outer rotor 5 rotates 22.5 degrees in the direction of the arrow and the inner rotor 7 rotates.
Is rotated by 45 degrees, A-10 has started the compression stroke, B-10 is the beginning of the combustion stroke, and the ignition port B-17 has been closed. C-10 is a little before the exhaust stroke, and the exhaust port C-15 is still closed. D
-10 is the place where the inhalation process has already started, and the inhalation port D-1
Only 6 is open. In Fig. 4, the outer rotor 5 is 45
With the inner rotor 7 rotated 90 degrees,
-10 is a place where the compression stroke has been completed by half, B-10 is a place where the combustion stroke has been completed by half, C-10 is a place where the exhaust stroke has been completed by half, and exhaust port C- Only 15 are open. D-
No. 10 is the one in which the suction stroke has been completed by half and only the suction port D-16 is open. In Fig. 5, the outer rotor 5 is 6
It rotates 7.5 degrees, the inner rotor 7 rotates 135 degrees, A-10 is at the beginning of the end of the compression stroke, ignition port A-1
