BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary engine which is one of internal combustion engines, and more particularly to a rotary engine having a rotor provided with a sliding plate.

[0002]

2. Description of the Related Art Conventionally, a reciprocating piston engine is a prime mover widely used not only in transportation such as automobiles and ships but also in various industrial fields such as agriculture and civil engineering. Various obstacles such as noise generation due to inertia of reciprocating parts such as valves are unavoidable. For this reason, a rotary engine that eliminates reciprocating motion and obtains power only in one direction has been proposed and put to practical use, and various improvements have been proposed in the past. For example, a Wankel engine, which is one of rotary engines, has a trochoidal curved surface formed on the inner circumference thereof, a rotor housing having an ignition plug and an exhaust hole, and the rotor housing is sandwiched in a sealed state from both sides. Fixed to each other and each of which has a center gear formed therein, and a side gear which is disposed in the rotor housing and meshes with the center gear formed in the side housing. A rotor shaped like a rice ball,
An eccentric shaft that is inserted into an internal gear formed in the side housing and is eccentric by an eccentric amount that deviates the tocolloid curve. Then, one cycle of suction, compression, explosion, and exhaust is completed in an approximately three crescent-shaped space which is formed by the inner peripheral surface of the rotor housing and the outer peripheral surface of the rotor and whose capacity is changed by the rotation of the rotor. By repeating this cycle, the eccentric shaft rotates. According to the rotor engine of the Wankel engine, since the motion obtained by the explosion of the fuel is the rotary motion, the mechanism is simplified and the volume is reduced unlike the conventional reciprocating piston engine. You can

Therefore, the present invention has been proposed in order to solve the problems of the above-described conventional rotary engine, and a rotary which can obtain an efficient rotation characteristic without using an eccentric shaft. The purpose is to provide an engine.

Hereinafter, the rotating operation of the rotary engine 1 of the present embodiment having the above-mentioned structure will be described step by step with reference to FIGS. 7 to 10. The rotors 3 shown in the respective drawings are all designed to rotate in the counterclockwise direction in FIG.
3 is shown with a dashed-dotted line, and the 2nd control rail 14 is shown with a dashed-two dotted line.

First, the state shown in FIG. 7 is the first sliding plate 9
The fuel is compressed in the space partitioned by the fourth sliding plate 12 (or one seal 20) and the second
In the space between the sliding plate 10 and the third sliding plate 11, the gas after the explosion is released to the outside through the first and second exhaust ports 16 and 17. At this time, the first sliding plate 9 is released from the state in which the sliding movement of the first groove 5 from the first groove 5 toward the inner peripheral surface 2a of the rotor housing 2 was regulated by the second regulating rail 14 until then. Just before the operation, the fourth sliding plate 12 is connected to the second regulation rail 14
The tip end is in contact with the inner peripheral surface 2a of the rotor housing 2 without being restricted by. Then, when the rotor 3 further rotates, as shown in FIG. 8, the fourth sliding plate 12 moves to the first
The regulation rail 13 regulates the sliding movement from the fourth groove 8, while the first sliding plate 9 is not regulated by the regulation rail 13 and the front end is the inner peripheral surface 2a of the rotor housing 2.
Contact with. Then, in the state shown in FIG. 8, the spark plug 15 operates and the compressed fuel explodes. Then, as described above, the first sliding plate 9 is not restricted by the first restricting rails 13, so that the first sliding plate 9 is further connected to the rotor housing as shown in FIG. While protruding toward the inner peripheral surface 2a side of the second member 2, the fourth sliding plate 12 is regulated by the regulating rail 13 and therefore maintains the same position as that shown in FIG. At this time, the rotor 3
Since the outer peripheral surface of the rotor 3 is in contact with the one seal 20 to keep airtightness, the outer peripheral surface 3a of the rotor 3 is formed with the notch 3b, so that the first slide plate A large pressure is applied to 9, and the first sliding plate 9
Since the slit 32 is formed in the inner surface of the rotor housing 2, the tip of the first sliding plate 9 is in close contact with the inner peripheral surface 2a of the rotor housing 2, thereby further improving the airtightness in the space and preventing the rotation loss. It Then, when the rotor 3 further rotates due to this explosion, as shown in FIG. 10, the first sliding plate 9
Passes through the first exhaust port 16. As a result, the gas generated by the explosion is discharged from the inside of the rotor housing 2. When the rotor 3 rotates further, the third
Like the first sliding plate 9, the sliding plate 11 is not regulated by the first regulating rail 13, so that the tip of the sliding plate 11 rotates while being in contact with the inner peripheral surface 2a of the rotor housing 2 and the rotor 2 of the rotor 2 rotates. Since the outer peripheral surface 3a is in contact with the other seal 21, the gas (residual gas) generated by the explosion is before the third sliding plate 11 reaches just before the first exhaust port 16. Substantially all is released, and further the third slide plate 11
The second outlet 1 formed in front of the other seal 21
When it reaches 7, it is completely released.

When the rotor 3 further rotates from the state shown in FIG. 10, the first sliding plate 9 and the fourth sliding plate 12 are respectively moved to the second sliding plate 10 and the third sliding plate 10 shown in FIG. The same state as that of the sliding plate 11 of FIG. Therefore, the operation of the second sliding plate 10 and the third sliding plate 11 will be described below to replace the description of the operation of the first sliding plate 9 and the fourth sliding plate 12 described above. That is, the third sliding plate 11 is the other seal 2
1, the outside air is sucked from the suction valve 18 between the third sliding plate 11 and the second sliding plate 10, and as shown in FIG.
Is injected into the rotor housing 2. At this time, the second sliding plate 10 that was previously restricted by the first restricting rail 13 is released from the restriction by the first restricting rail 13, while the third sliding plate 11 is controlled by the first restricting rail 13. The regulation rail 14 of No. 2 regulates the sliding movement, and further the rotor 3
Since the outer peripheral surface 3a of the above is in contact with the one seal 20, the fuel is gradually compressed as the rotor 3 rotates as shown in FIG. Then, the second sliding plate 10 and the third sliding plate 11 are in the same state as the first sliding plate 9 and the fourth sliding plate 12 shown in FIG. 7 again. In addition,
As shown in FIG. 8, the compressed fuel remains in the state of being blocked by the first sliding plate 9 and the fourth sliding plate 12 by the first notch 3b formed on the outer peripheral surface of the rotor 3. Move to the state shown.

As described above, according to the rotary engine 1 of the present embodiment, since the rotor 3 rotates at the center of the rotor housing 2, it is not necessary to use the eccentric shaft as a constituent element unlike the conventional rotary engine. Therefore, not only efficient rotation characteristics can be obtained, but also the outer peripheral surface 3a of the rotary 3 and the first sliding plate 9 and the third sliding plate 9
Since the first and second notches 3b and 3c for increasing the thickness receiving area of the sliding plate 11 are formed, the rotational force due to the explosion can be further increased. Further, slits 32 and 33 are formed on one side surface of the first sliding plate 9 and the third sliding plate 11, respectively, and the slits 32 and 33 are inclined toward the inner peripheral surface 2a of the rotary housing 2. Therefore, at the time of explosion, the first and third sliding plates 9 and 9 are released from the sliding restriction by the first restriction rail 13.
The tip of 11 slides in a state of being in close contact with the inner peripheral surface 2a of the rotary housing 2, and as a result, the gas compressed by the explosion does not leak from the first and third slide plates 9 and 11. Therefore, it is possible to obtain a rotating force with no further loss. In addition, the first and third sliding plates 9 and 1
1 and the first upper cutting portions 26 and 27 through which the second regulation rail 14 is inserted and the second and fourth sliding plates 10 and 12 and the first regulation rail 1
Bearings 28, 29, 30, 31, 38, 39, and 38 are respectively inserted in the second lower cutting portions 36, 37 through which 3 is inserted.
Since 40 and 41 are formed respectively, smooth rotation of the rotor 3 can be realized.
