Abstract

PURPOSE:To reduce nonuniform rotation and abrasion of a power transmitting part by providing the inside of a housing with a rotor rotating together on an output shaft so as to form a ring space in its periphery, and installing both a projected part which cuts off the ring space, and a partition plate which intermittently opens/closes the ring space. CONSTITUTION:When a rotor 2 rotates clockwise, a ring space 3 is closed by a partition plate 6, and when a projected part 4 of the rotor 2 passes the position of a closed compressed fuel gas supply valve 9 closed, the compressed fuel gas supply valve 9 is opened, so that the compressed fuel gas 13 from a compressed fuel gas feeder 10 is sucked into a combustion chamber 11. At this time, in an exhaust chamber 12 an exhaust valve 7 is opened and exhaust gas 14 is exhausted by means of rotation of the projected part 4. When the projected part 4 passes a place where an ignition device 8 is placed, the compressed fuel gas supply valve 9 is closed, and the compressed fuel gas 13, which is ignited by the ignition device 8 and supplied to the combustion chamber 11, is exploded for combustion. As a result, the rotation of the rotor 2 can directly be taken out as power via an output shaft 5.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a rotary engine.

[Prior Art] In a conventional rotary engine, the triangular point of the approximately triangular rotor rotates while contacting the inner surface of the cocoon-shaped housing, and the volume change created at this time causes absorption and absorption.
It performs four stages: compression, explosion, and exhaust.

The rotation of the rotor at this time is not a perfect circular motion, but an eccentric planetary motion that moves along a fixed trajectory.

The rotary engine extracts the planetary motion of the rotor as rotation of an output shaft and obtains rotational force.

[Problems to be Solved by the Invention] Therefore, conventional rotary engines have the problem of uneven rotation because the rotor performs planetary motion. The problem was that the gear mechanism was extremely complex, and the power transmission part suffered from severe wear.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rotary engine that has a simple configuration, has less uneven rotation, and can reduce wear on the power transmission section.

[Means for Solving the Problems] The present invention includes a rotor in a housing that rotates integrally around an output shaft and forms a ring-shaped space on the outer periphery. A protrusion that blocks the ring-shaped space is formed, and a partition plate that can intermittently open and close the ring-shaped space is provided at a predetermined position of the housing, and a compressed fuel gas supply valve is provided on one side near the partition plate. This rotary engine is characterized by having an ignition device and an exhaust valve on the other side.

[Function] At the same time as the protrusion provided on the rotor passes the position of the partition plate, the ring-shaped space is shut off by the partition plate, the compressed fuel gas supply valve is opened to take in the compressed fuel gas, and the exhaust valve is opened. Start exhausting the previous combustion gas. Next, the compressed fuel gas supply valve is closed, and the compressed fuel gas is exploded by the igniter, and the expansion of the gas pushes the protrusion and rotates the rotor, thereby obtaining output through the output shaft and simultaneously exhausting the gas. When the explosion, expansion, and exhaust are completed, the partition plate is brought into a state where the protrusion can pass through, allowing the protrusion to pass through. Thereafter, the above steps are repeated and performed continuously.

〔Example] Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 (A) and (B) show an embodiment of the present invention.

As shown in FIGS. 1 and 2, a circular rotor 2 that rotates around an output shaft 5 is provided inside the housing 1, and a ring-shaped space 3 with a desired diameter is formed around the outer circumference of the rotor 2. has been done.

A protrusion 4 is integrally provided on the outer circumferential surface of the rotor 2 and can protrude radially outward to block the ring-shaped space 3.

A protrusion 4 of the rotor 2 is provided at a predetermined position of the housing l.
A partition plate 6 is provided that moves up and down to open and close the ring-shaped space 3 in synchronization with the rotation of the ring-shaped space 3.

Further, in the housing 1, an ignition device 8 and a compressed fuel gas supply valve 9 are provided near one side of the partition plate 6, and an exhaust valve 7 is provided near the other side of the partition plate 6. There is. Further, the compressed fuel gas supply valve 9 is connected to a compressed fuel gas supply device IO.

The ring-shaped space 3 described above is divided by the partition plate 6 and the protrusion 4, and includes an ignition device 8 and a compressed fuel gas supply valve 9.
The space in contact with the combustion chamber 11 becomes a combustion chamber 11, and the space excluding the space that becomes the combustion chamber 11 becomes an exhaust chamber 12.

Figures 3 to 3E are diagrams showing the stroke of the rotary engine of the present invention.

Figure 3 shows the intake and exhaust strokes, and rotor 2 is indicated by arrow a.
When the protrusion 4 of the rotor 2 passes the position of the closed compressed fuel gas supply valve 9, the ring-shaped space 3 is closed by the partition plate 6. 9 is open, and compressed fuel gas 13 from the compressed fuel gas supply device 10 is sucked into the combustion chamber 11 . At this time,
In the exhaust chamber 12, the exhaust valve 7 is in an open state, and the exhaust gas 14 is exhausted by the rotation of the protrusion 4 of the rotor 2.

Further, the compressed fuel gas 13 supplied from the compressed fuel gas supply device IO is compressed to a high enough pressure to ignite and explode to rotate the rotor 2.

FIG. 3(B) shows the explosion/exhaust stroke. When the rotor 2 rotates in the direction of the arrow a, the projection H4 passes the location where the ignition device 8 is installed, and the compressed fuel gas supply valve 9 closes. , the ignition device 8 electrically ignites the compressed fuel gas 13 supplied into the combustion chamber 11 to explode and burn it.

As the inflation gas pressure at this time acts on the protrusion 4,
The rotor 2 obtains rotational force, and the rotation of the rotor 2 is directly extracted as power through the output shaft 5.

Also, at this time, in the exhaust chamber 12, the exhaust gas 14 is being exhausted from the opened exhaust valve 7, as in the case shown in FIG.

FIG. 3(C) (DJ) (E) shows the cycle switching stroke, and as the explosion/exhaust stroke in FIG. 3(B) approaches the end, the protrusion 4 reaches the exhaust valve 7 as shown in FIG. When it approaches, the exhaust valve 7 is closed and the partition plate 6 moves (retreats) in the direction of the arrow.

Next, as shown in FIG. 3(D), when the protrusion 4 finishes passing the position of the exhaust valve 7, the exhaust valve 7 opens again and the protrusion 4
passes through the position of the retracted partition plate 6.

Furthermore, as shown in FIG. 3 (ε), when the protrusion 4 finishes passing through the position where the partition plate 6 is provided, the partition plate 6 moves again in the direction of arrow C so as to form the combustion chamber 11. Then, the process returns to the process shown in FIG. 3, and this process is repeated thereafter.

The rotation of the rotor 2, the movement of the partition plate 6, and the opening and closing of the compressed fuel gas supply valve 9 and exhaust valve 7 are synchronized by a cam or the like.

As mentioned above, the rotor 2 is rotated by performing the three strokes of intake, explosion, and exhaust, and the stroke of the partition plate that switches the cycle, and the rotation is transmitted through the output shaft 5 that is integrally formed on the axial center of the rotor 2. It can be extracted as power.

At this time, since the rotor 2 and the output shaft 5 are integrally formed, there is no uneven rotation, and a constant power can be stably extracted.

The fourth drawing (to)) and the one shown in FIG. 5 (■) show the case where the partition plate is formed as a rotating body.

That is, a partition rotating plate (partition plate) 1 rotates around a rotating shaft 16 located perpendicular to the output shaft 5 of the rotor 2.
7 is provided, and a four part 15 is formed at a predetermined position of the partition rotary plate 17 so that the protrusion 4 of the rotor 2 can pass therethrough, and the partition rotary plate 17 is connected to the rotor 2 through a gear or the like. It is designed to rotate in synchronization with the rotation of.

That is, as shown in FIG. 4(A) (13+), when the protrusion 4 of the rotor 2 comes to the position of the partition rotation plate 17, the recess 15 of the partition rotation plate 17 corresponds to the protrusion 4 and Pass part 4.

Further, as shown in FIGS. 5(A) and 5(B), when the protrusion 4 does not pass through the recess 15, the partition rotating plate 17 closes the ring-shaped space in the same way as the partition plate 6 shown in FIG. 3 is divided into a combustion chamber 11 and an exhaust chamber 12.

Note that the rotary engine of the present invention is not limited to the above-described embodiments, and may include a plurality of protrusions, partition plates, exhaust valves, compressed fuel gas supply valves, and ignition devices at required positions. It goes without saying that the rotational direction of the rotor is not limited to the embodiment, and that various other changes can be made without departing from the gist of the invention.

[Effects of the Invention] As explained above, according to the rotary engine of the present invention, since the rotor and the output shaft are integrally formed with the same center, there is no uneven rotation and stable and constant power can be obtained. I can do it.

In addition, it can have a simple configuration, which has the excellent effect of suppressing abrasion of the constituent members and prolonging their service life.
