The present invention relates to a rotary engine that causes a change in volume around a shaft so that rotational force is transmitted directly to the shaft.

In other words, insert a rotor that is non-constantly rotating in the same direction in a cylindrical casing that is integral with the drive shaft and rotates at constant speed, and according to the mutual position of the exhaust element integrated with the cylindrical casing and the intake element integrated with the rotor, The space between the elements, that is, the cylinder, changes its volume and thus is carried out in four strokes of suction, compression, explosion, and exhaust, and is integrated with the cylindrical casing when it is rotated by applying force to the cylindrical casing with the explosive force generated at this time. The present invention relates to a rotary engine capable of achieving high power with a small, light weight and minimum mechanical heat loss.

In addition, the present invention is a rotary engine that generates a volume change in the combustion chamber (cylinder) around the drive shaft, the rotational force is directly transmitted to the drive shaft, is ignited by the spark plug and exploded, performing four strokes of intake, compression, explosion, exhaust Can be classified as a four-stroke internal combustion engine.

Before explaining the present invention, a four-stroke internal combustion engine will be described. The four-stroke internal combustion engine is a gasoline engine, which has been continuously developed and developed for many years, and has recently improved thermal efficiency.

In general, however, a four-stroke internal combustion engine has a plurality of cylinders mounted transversely to a cylinder block, and the pistons are connected to each other in the crankshaft by connecting rods to the reciprocating motions. Driving force is gained.

The crankshaft driven by the reciprocating piston is developed and developed under the basic concept that one cycle of intake, compression, explosion and exhaust is completed in one cylinder in two revolutions.

As such, the crankshaft means one explosion per two revolutions means that the explosion energy obtained through one explosion per piston is consumed in the engine's internal power transmission process to rotate the crankshaft two times in addition to the driving force.

That is, it is easy to see that a large amount of motion loss is generated during the process of reciprocating the piston by the explosive force in the cylinder and changing the crankshaft into the rotational motion by the connecting rod. Since the camshaft that opens and closes the exhaust valve is also connected to the crankshaft, not all of the rotational force of the crankshaft is consumed by the driving force of the engine. Since the connecting rod connecting the piston to the shaft and the camshaft driving the suction, exhaust, and valve are all integrally inserted into the cylinder block, the conventional four-stroke internal combustion engine has been a bulky weight body, and its thermal efficiency is never 30. It did not exceed%.

As such, the conventional four-stroke internal combustion engine has been developed and developed without breaking the basic concept of obtaining a driving force by converting the reciprocating motion of the piston into a rotational motion, and thus the results have been limited in spite of long-term efforts. Therefore, in order to drastically reduce the size and weight of the four-stroke internal combustion engine and increase its mechanical efficiency, it explodes once in two revolutions of the crankshaft of the conventional four-stroke engine and reciprocates in several cylinders inserted in a line in the cylinder block. It is necessary to develop and move completely from the conventional structure in which the moving Pison tone is changed to the rotational motion by the connecting rod.

The present invention has been devised based on the basic principle, and has a cylinder that rotates around the drive shaft and when the cylinder causes a volume change, the explosive force generated by four strokes of suction, explosion, compression, and exhaust is directly transmitted to the drive shaft. In this case, a large driving force can be obtained in a unit time, and the engine can be made smaller and lighter.

In particular, the present invention is a further development of the "rotary engine" filed by the present application in 1991 Patent Application No. 1154, which further reduces the size of the engine compared to the previous application, and more precisely open and close the intake and exhaust valves Thus, more stable combustion can be performed in the cylinder.

Further, each intake element 6 has a spark plug 23 inserted therein, and an end portion has several grooves 6 ″ into which an oil ring (not shown) and a compression ring (not shown) are inserted. . In addition, several exhaust elements 3 (four are shown in the figure) which are integrally protruded into the drive shaft 1 and the integral cylindrical casing 2 are exhaust holes 3 which are conducted to the outside of the cylindrical casing 2, respectively. And an exhaust valve 15 for opening and closing the exhaust hole 3 'is inserted, and an exhaust valve actuating lever 17 in the shape of a base (a) is inserted at the rear end of the exhaust valve 15.

It has the cooling water jet hole 25 'blown into the exhaust path 26, and is connected with the cooling water supply pipe 24 of the outer cylinder 11. As shown in FIG.

In addition, the outer cylinder 11 has an exhaust passage 26 and an exhaust pipe 11 'which is integral with the block body 13 by a central shaft 12 having an intake pipe 12' through which the mixed gas flows. It is connected to, and the block 14 for preventing reverse rotation is inserted between the shaft (5) of the roller (4) inserted into the block body 13 is inserted.

Looking at the operating state of the present invention having such a structure and its effects as follows. The rotary engine of the present invention is initially driven by the starting motor as in the conventional engine.

When the driving shaft 1 is driven by the starting motor, the cylindrical casing 2 integrated with the driving shaft 1 is driven in the arrow direction (clockwise) shown in FIG.

At this time, the cylinders A, B, and C which are the inside of the cylindrical casing 2 through the intake hole 6 'are mixed gas in which air and fuel are already introduced into the intake passage 38 through the intake pipe 12'. , D enters.

The mixed gas flowing into the cylinder formed inside the cylindrical casing 2 is compressed between the intake element 6 of the rotor 4 and the exhaust element 3 of the cylindrical casing 2 and then inserted into the intake element 6. When the explosion is ignited by the spark plug 23, the explosive force exerts a force on the exhaust element 3 when it explodes, and the cylindrical casing 2 protruding there is rotated under the force, and the cylindrical casing 2 and The integrated drive shaft 1 is to be driven.

Looking through the graph (Fig. 6) showing the interaction state of the cylindrical casing (2) rotated in this way and the rotor (4) inserted into the inside thereof is as follows.

As can be seen from the graph, when the cylindrical casing 2 rotates once, the rotor 4 also rotates once, indicating that the rotation ratios of the cylindrical casing 2 and the rotor 4, that is, R, P, and M, are the same.

However, the cylindrical casing 2 makes constant speed rotation while the rotational amount per unit time is constant, but the rotor 4 performs non-constant speed rotation in which the rotational amount per unit time is not the same.

That is, as can be seen in the graph, the cylindrical casing 2 performs constant speed rotation with a constant rotation rate per unit time. However, the rotor 4 stops from 0 o'clock to 1/16 o'clock, starts to rotate after 1/16 o'clock, and makes 4/16 o'clock at 4/16 o'clock. The rotor 4 then stops from 4/16 o'clock to about 5/16 o'clock, and then resumes rotation after about 5/16 o'clock, and turns 8/16 when it reaches 8/16 o'clock. It will make non-rotational rotation.

In this way, the space between the intake element 6 protruding from the non-constantly rotating rotor 4 and the exhaust element 3 protruding from the cylindrical casing 2 rotating at constant speed, that is, the volume of cylinders A, B, C, D As a result, the intake, compression, explosion and exhaust strokes are performed in the cylinder.

In addition, as shown in FIG. 7, the cylinders A and C facing each other perform the same stroke, and the cylinders B and D perform the same stroke.

Looking at the cycle of the cylinder (A) here as follows.

The suction stroke in which the mixed gas flows into the cylinder A is performed during the period when the rotor 4 is stopped, that is, between 0 o'clock and 1/16 o'clock, and at 1/16 o'clock when the rotor 4 is rotated. The compression stroke takes place until 4/16 o'clock, and is exploded by the spark plug 23 at 4/16 o'clock, the highest compression point.

Thereafter, the period during which the rotor 4 is stopped applies a driving force to the cylindrical casing 2 protruding from the exhaust element 3 when it expands from 4/16 o'clock to 5/16, and the rotor 4 rotates again. The exhaust stroke is completed from 5/16 o'clock to 8/16 o'clock, and the first cycle of the cylinder A is completed.

In this manner, one cycle of the cylinder A is completed while the drive shaft 1 is rotated 180 ° (1/2 revolution).

In the same way, when the drive shaft (1) rotates 1/2 from 180 ° to 360 ° again, another cycle is completed. Therefore, two cycles are performed when the rotor (4) and the cylindrical casing (2) rotate once. You are done.

As described above, in the present invention in which one cycle is completed when the drive shaft 1 rotates 180 °, the intake element 3 is rotated at a constant speed like the cylindrical casing 2 and the rotor 4 so as to rotate at a constant speed. The interrelationship of 6) is as follows.

Initially, the intake element 6 protrudes in the rotor 4 when the exhaust element 3 is moved by starting the constant rotation of the cylindrical casing 2 with the intake element 6 and the exhaust element 3 in close proximity. ) Is the intake valve 19 is opened for 1/16 hours that is stopped, the adsorption gas is introduced into the cylinder (A). After about 1/16 hours, the intake valve 19 is closed and the intake element 6 moves as the rotor 4 rotates. At 4/16 o'clock, the ignition plug 23 inserted into the intake element 6 causes an explosion in the cylinder A, and at 5/16 o'clock when the rotor 4 is stopped. By 16 o'clock the cylinder A will expand.

As described above, since the rotor 4 is stopped, the expansion force in the cylinder A is applied to the exhaust element 3 that is rotating at constant speed, and the cylindrical casing 2 protruding the exhaust element 3 exerts a force. It will receive and drive.

Thereafter, the exhaust valve 15 inserted into the exhaust element 3 is opened in 5/16 hours, and exhaust is completed by 8/16 o'clock, thereby completing the first cycle. Next, look at the relationship between the cylindrical casing (2) rotating at constant speed and the rotor (4) rotating at a constant speed as follows.

When the ratio of the teeth of several driven gears 9 (four are shown in the figure) to the ring gears 8 fixed to the inner wall of the cylindrical casing 2 is 4: 1, the ring gears 8 When one rotation of the driven gear (9) is made four revolutions, four rotation of the driven gear (9) means four rotations of the drive pin (10) at the end of the driven gear (9), drive pin (10) The internal Geneva cam 7 of the inserted rotor 4 is operated four times. Since the Geneva cam 7 rotates 90 ° by the one-time operation of the Geneva cam 7, the four-time operation of the Geneva Cam 7 rotates 360 °, that is, the rotor 4 by one rotation. The graph of FIG. 6 shows that R, P and M of the casing 2 are the same.

In this way, when the drive shaft 1 rotates, the cylindrical casing 2 integrally rotates together, and when the driven gear 9 rotates by the ring gear 8 inserted therein, the shaft of the driven gear 9 rotates. The drive pin 10 of 9 'is inserted into the Geneva cam 7 formed on the bottom of the rotor 4, and the Geneva cam 7 is intermittently rotated when the rotor 4 is rotated. Since the intermittent rotation degree of the rotor 4 can be arbitrarily adjusted according to the configuration of the), it is possible to achieve the best thermal efficiency when arbitrarily manufactured according to the fuel and compression ratio used.

Thus, since the drive pin 10 of the driven gear 9 is inserted into the Geneva cam 7 formed on the bottom of the rotor 4, the rotor 4 does not have to be rotated backwards.

However, it explodes at the time when the rotor 4 which explodes the mixed gas compressed in the combustion chamber, ie, the cylinder, stops, and the explosion force drives the exhaust element 3 clockwise.

This explosive force also acts on the intake element 6 located in the counterclockwise direction to exert a force in the counterclockwise direction on the rotor 4 protruding from the intake element 6, thus forming a Geneva cam formed on the bottom of the rotor 4. There is a fear that the driving pin 10 inserted in (7) will be impacted.

In this way, when a force is applied to the rotor 4, the drive pin 10 inserted into the Geneva cam 7 may be cut off, and thus, between the block body 13 and the shaft 5 of the rotor 4 which do not rotate. Inserting the ball latch 14 to be rotated in only one direction to the rotor 4 to prevent the reverse rotation.

The ball latch 14 is composed of a spring 14 " and a ball 14 ', but a reversal prevention mechanism composed of a bearing and a tooth may be used.

Thus, the intake valve 6 inserted in the cylindrical casing 2 and the rotor 4 which is inserted into the cylindrical casing 2 and the rotor 4 rotated to the same R, P, M in the same direction, respectively, is inserted into the intake valve 6 19) and the operation relationship between the exhaust valve 15 is as follows.

That is, the air inlet (a) -shaped intake, which is inserted into the intake element 6 and opens and closes the intake hole 6 ', penetrates the wall of the rotor 4 and is leaked into the pin 21 ″. One side of the valve actuating lever 21 is inserted, and the other side inserts the roller 22, and the roller 22 travels the intake passage 38 which is a distance between the rotor 4 and the block body 13. Done.

In this way, the roller 22 traveling along the outer circumferential surface of the block 13 in the intake passage 38 is operated by the protrusion 13 ″ of the block 13 so that the intake valve opening / closing valve 21 is operated to intake the valve. (19) will be opened and closed.

In addition, at the rear end of the exhaust valve 15 inserted into the exhaust element 3 to open and close the exhaust hole 3 ', an air space (a) shape penetrating through the wall of the cylindrical casing 2 and retained as a pin 17' One side of the exhaust valve opening / closing lever 17 is inserted, the other side of which the roller 18 is inserted, and the roller 18 has an exhaust passage 26 which is a distance between the outer cylinder 11 and the cylindrical casing 2. Will drive).

In this way, the roller 18 traveling along the inner circumferential surface of the outer cylinder 11 in the exhaust passage 26 is operated by the thick portion 11 ″ of the inner wall of the outer cylinder 11 to open and close the exhaust valve 15. .

In this way, the outer cylinder 11 having the thick portion 11 ″ on the inner side has an exhaust gas exhaust pipe 11 'and a cooling water supply pipe 24 on the outside, and has an intake pipe 12' on the inner side thereof. It is connected integrally with the block body 13, the cylindrical casing (2) is rotated because the main body is operated, that is, the cylindrical casing (2) and the rotor (4) to maintain a fixed state that does not rotate when rotating ) And the exhaust valve actuating lever 17 and the intake valve actuating lever 21 inserted and inserted through the rotor 4 can be operated at the correct time to accurately set the opening and closing timing of the intake valve 19 and the exhaust valve 15. It was.

In addition, several indentations 6 ″ and 3 ″ are formed at ends of each intake element 6 into which the intake valve 19 is inserted and each exhaust element 3 into which the exhaust valve 15 is inserted. The oil ring and the compression ring are inserted here to maintain airtightness.

In addition, the cylindrical casing 2 is provided with a cooling water inlet 25 connected to the cooling water supply pipe 24 of the outer cylinder 11 to cool the cylindrical casing 2, and at the same time, an exhaust passage ( A cooling water jet hole 25 'sprayed in the direction of 26) was drilled to cool the combustion gas.

As described above, the present invention can be manufactured small in size and light in weight because of the low number and simple parts, and high output can be obtained in comparison with its volume.

That is, in the present invention, since two explosions are generated in one cylinder when the drive shaft 1 rotates once, eight explosions are generated when the number of cylinders is configured as four as A, B, C, and D as shown in the drawing. You can get it.

If the number of cylinders in the cylindrical casing (2) is composed of six, the drive shaft may obtain more powerful force by obtaining 12 explosions in one revolution.

As described above, the present invention drives the drive shaft directly with the explosive force obtained from the cylinder around the drive shaft, thereby minimizing mechanical heat loss, obtaining high power per unit time, and generating a centrifugal force around the drive shaft so that the drive shaft is always perpendicular to the ground. It is a very useful invention that can be used more appropriately as a helicopter engine than an automobile engine because of the force to be generated.
