Abstract

PURPOSE:To reduce the noise and vibration of an internal-combustion engine and to simplify manufacture of the same, by providing a block on the inner surface of a rotary casing having an intake port, an exhaust port and an ignition port formed in its side face, and also providing a pivotally movable piece in the manner that it is held in contact with said block at one end thereof. CONSTITUTION:When an opening 3C and intake port 4E are communicated with each other along with rotation of a rotary casing 3, one end of a pivotally movable piece 3D moves upward along the surface of a block 3F and a sliding surface 3E, and air- fuel mixture is drawn into the rotary casing 3. With subsequent rotation of a crank 7', the pivotally movable piece 3D is then moved downward, and mixture is compressed. When the casing 3 is turned to the position of an ignition plug 4F, mixture is ignited and exploded. Then, the pivotally movable piece 3D is turned upward along the sliding surface 3E pivotally around a point P, and the crank 7' is turned by the intermediary of a connecting plate 10. With subsequent upward and downward movement of the piece 3D, combustion gas is exhausted when the opening 3C is communicated with the exhaust port 4D and mixture is drawn into the casing 3 when the opening 3C is communicted with the intake port 4E. Thus, it is enabled to reduce the noise and vibration and to facilitate machining operation.

Description

[Detailed description of the invention] The present invention relates to internal combustion engines.

Conventionally, in the case of an internal combustion engine, λ is a gasoline engine.
There are two types of engines: reciprocating type engines and rotary type engines.

However, conventional reciprocating engines require an intake valve and an exhaust valve that operate in synchronization with the reciprocating motion of the piston, so the mechanism is complicated, and the piston has a gap between the piston and the cylinder. Slap occurs and is a major cause of engine noise and vibration. Furthermore, in order to smooth the output rotation of the engine, a large number of cylinders must be arranged in parallel or radially, which forces the overall size of the engine to increase.

Further, in a rotary engine, the outer shape of the rotor and the inner circumferential surface of the housing housing the rotor must be formed to form an evitrochoid line, which is difficult to process with high precision.

This invention has been made in view of the above circumstances, and it is an object of the present invention to provide an internal combustion engine that is free from noise and vibration and is easy to process.

Next, with reference to the drawings, 2- I will explain while doing so.

FIG. 1 is a longitudinal cross-sectional view showing an embodiment of the present invention.
2 is a sectional view taken along the line II-n in FIG. 1, and FIG. 3 is a side view showing the embodiment.

An internal combustion engine 1, which is an embodiment of the present invention, is configured as follows. That is, 2 is a cylindrical reversing gearbox, and 3 is a disc 3 facing oppositely.
A rotary housing formed in a cylindrical shape with A and 3B,
The reversing gearbox 2 is fixed to the disc 3A surface of the rotating casing 3 so that the reversing gearbox 2 is located on the same center line as the center line of the rotating casing 3. Reference numeral 4 denotes a circular plate 4B that can make sliding contact with the outer surface of the disc 3A and has an opening 4A having a diameter larger than the outer diameter of the reversing gearbox 2, and a corresponding circular plate 11. 4C and is formed into a circular shape, and houses the rotary housing 3 so that the reversing gearbox 2 protrudes from the opening 4A.

An output shaft 5 is pivotally supported on the center line of the reversing gearbox 2, and a reversing gear mechanism is built therein.

The reversing gear mechanism is attached to the tips of the output shirts 1 to 5 in the reversing gear box 2, and the rotating shafts are arranged at 120 degrees centigrade between the first bevel gear 2A and the first bevel gear 2B.
three free bevel gears 2C that are attached to form an angle and mesh with the first bevel gear 2A, and a second free bevel gear 2C that meshes with the three free bevel gears 2C and is attached to the tip of the crankshaft 6. The output shaft 5 has a bevel gear 2D, and is configured such that the output shaft 5 rotates in the reverse direction when the crankshaft 6 rotates in the normal direction.

The rotary housing 3 has a long hole 3C along the circumference near the circumference of the disk 3A surface, and the rotary housing 3
Crankshaft 6.6 located on its center line within
', a crank 7.7', and a crank pin 8. Roughly speaking, within the circumferential side of the rotating housing 30, there is a swinging piece 3D that is swingable about a fulcrum P.
and a sliding movement 3E that can make vaginal movement contact with the tip surface of the swinging piece 3D.
The swinging piece 3D has a block 3F having a block 3F.

A combustion chamber is formed by the sliding surface 3E of the block 3F, the inner wall surfaces of the disks 3A and 3B, and the inner wall of the circumferential side. and,
In the swinging piece 3D, the other end of the engagement plate 10, whose one end is connected to the crank bin 8, is pivotally supported on a holding member 3G, and the reciprocating swinging movement of the swinging piece 3D is converted into the rotational movement of the crank i structure. It is supposed to be converted.

In the storage case 4, the elongated exhaust port 4D and the intake port 4E are connected to the circular plate 4B so that the opening 3C formed in the disk 3A opens on the rotation locus drawn by the rotation of the disk 3A.
Further, a spark plug 4F is provided on the circular plate 4B so as to be located on the rotation locus. In addition, 4
G indicates an exhaust vibrator, and 4H indicates an intake pipe. The positions of the exhaust port 4D, intake port 4E, and spark plug 4F can be appropriately determined so that intake, compression, explosion, and exhaust can be performed as one cycle during one rotation of the rotating housing 3. .

4- Next, the operation of the internal combustion engine 1 having the above configuration will be explained.

As shown in FIG. 4, just before the combustion gas is completely exhausted from the combustion chamber, the exhaust port 4D and the opening 3C slightly overlap, and the combustion gas is exhausted from this overlapped portion. 3D is in a state close to the inner wall of the circumferential side of the rotating housing 3.

When the rotating housing 3 rotates in the six directions shown by the arrows due to inertial force, the opening 3C no longer overlaps the exhaust port 4D, the end of the opening 3C approaches the intake port 4E, and the opening 3C and the intake port 4E overlap. Initially, fuel gas begins to be injected into the combustion chamber from the intake port 4E. When the rotating housing 3 continues to rotate further, the end of the swinging piece 3D moves up the sliding surface 3E of the block 3F, and the intake of fuel gas continues. As shown in FIG. 5, just before the volume of the combustion chamber reaches its maximum, the intake port 4E and the opening 3G slightly overlap.

Next, when the rotating housing 3 rotates in the six directions shown by the arrow, the end of the swinging piece 3D displaces the Ig-IJ surface 3E of the block 31- in the direction of the arrow B by the rotation of the crank 7' (7) in the direction shown by the arrow. Then, compression of the combustion gas is started.

As the rotary housing 3 rotates, the rear part of the sliding piece 3D descends, and as a result, the fuel gas becomes maximally compressed as shown in FIG. At this point, a spark plug 4F is located at the end of the frontage portion 3C, and the fuel gas explodes and burns when the spark plug 4F ignites.

The rocking piece 3 is caused by the expansion of the combustion gas due to the explosion of the fuel gas.
The end of D rises on the sliding surface 3F- of the block 3F, and the U movement about the fulcrum P of the swinging piece 3D moves the engagement plate 10
is transmitted to the rank mechanism as a rotational motion, and is taken out as an output shirt (.5 rotations).

As shown in FIG. 7, the volume of the combustion chamber reaches its maximum as the rotating housing 3 rotates, and then, due to the rotation of the rotating housing 3 due to inertia, the opening 3C begins to overlap the exhaust port 4D, causing combustion inside the combustion chamber. Gas exhaust begins and the state returns to the state shown in FIG. 4.

As shown above, during one rotation of the rotating housing 3, fuel gas is taken into the combustion chamber, fuel gas is compressed, fuel gas is exploded and expanded, and combustion gas is exhausted. The reciprocating rocking motion is converted into rotational motion by the crank mechanism, and output can be taken out as rotation of the output shaft 5.

Moreover, no piston slap occurs during the rocking motion of the rocking piece 3D, and since the block 3F uses the rotating housing 3 as a flywheel, the output shaft 5 rotates smoothly with no noise and less vibration. power can be extracted. Furthermore, since each part of the device including the rotating housing 3 has a simple shape, the internal combustion engine can be manufactured easily and easily.

Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and can be implemented with appropriate modifications within the scope of the gist of the invention. Needless to say.

FIG. 8 is a partially sectional view showing another embodiment of the invention.

7- The Uchiura engine, which is another embodiment of the present invention, corresponds to a conventional three-cylinder reciprocating engine, and the rotating housing 3
Three blocks 31 are arranged 120° rotationally symmetrically on the inner wall of the circumferential side of
-1.31.3J is arranged, and one end is slidably in contact with 31.3M on each sliding surface 3 of the three blocks 3H, 31, 3J, and inside the circumferential side of the rotating housing 3. Three swinging pieces 3N, 3P, and 3Q that pivotally support the other end are arranged so as to be swingable, and each swinging piece 3N, 3P, and 3Q has an engaging portion t411.
12.13, and the other parts are the same as in the previous embodiment.

Each of the swing pieces 3N, 3P, and 3Q swings in different phases, and the swing motion is extracted as a rotational motion of the output shaft 5.

In the other embodiments described above, the rotation of the outlet shaft 5 can be made even smoother, and the horsepower can be increased even more.

As described in detail above, according to the present invention, it is possible to provide an internal combustion engine that generates less noise and vibration and is easy to manufacture. The internal combustion engine according to the present invention is suitable as a power source for vehicles such as motorcycles and automobiles.
