Description

The present invention relates to a rotary engine mechanism that outputs power by an engine mechanism that simplifies the structure and changes reciprocating motion to rotational motion, and in particular, a rotary air supply / exhaust valve that can rotate 360 degrees inside an air supply / exhaust groove provided in a base, In combination with the design of the correct supply / exhaust timing, and by combining the operation of the cross-type rotary locking arm and crank journal installed in the drive unit set, the rotation reduction ratio design between the gear sets enables the intake of the engine The present invention relates to a four-stroke engine that does not have a crankshaft and an air valve that can achieve a four-stroke circulation operation of compression, combustion, and exhaust.

The current engine cycle is nothing but two or four strokes (ie, two or four strokes). In addition, the engine is powered from the crankshaft. That is, the crankshaft becomes the power output shaft of the entire engine. However, the crankshaft is not a straight shaft body from the front end portion to the end portion, and the piston changes the reciprocating motion up and down into the rotational motion, so that the crankshaft is formed with a refractive shaft that matches the number of pistons. Therefore, when the piston reciprocates up and down, it often causes eccentricity in the refracting part of the crankshaft, and when the piston reciprocates up and down while being biased, a lateral force is applied to the piston and it comes into contact with the cylinder The piston is damaged by long-term friction.

Furthermore, unless a plurality of air valve sets are mounted inside the known engine, it is impossible to provide intake, compression, combustion, and exhaust strokes to the cylinder. In terms of the structure of the institution, it is a little complicated.

The main object of the present invention is to control the gear assembly structure in which the linkage between the crank journal or the cross-shaped rotary locking arm and the air supply / exhaust valve forms a constant rotational speed ratio, whereby the air supply / exhaust valve rotates continuously, The purpose is to provide a four-stroke engine that does not have a crankshaft and an air valve, and continuously circulates the four strokes of intake, compression, combustion, and exhaust, by operating the intake and exhaust strokes in multiple cylinders. provide.

The next object of the present invention is to provide a feature of the rotation system in which the supply / exhaust valve of the operating gear connected to the inside of the gear set rotates at a position of 360 degrees inside the base through a special speed reduction process by the gear set structure. In addition, the intake and exhaust strokes can be performed inside the base, and the rotation speed ratio of the cross-shaped rotary rocking arm ≧ 2 times the rotation speed ratio of the supply / exhaust valve can be obtained. The purpose is to provide a four-stroke organization.

Another object of the present invention is to completely wear out the piston and cylinder without applying lateral force because the push rod connected to the piston forms a reciprocating motion in the vertical direction in the engine structure of the rotary power output. The purpose of the present invention is to provide a four-stroke engine without a crankshaft and an air valve that can be avoided and extend the service life of the engine.

Another object of the present invention is to select an appropriate length in the straight direction of the fixing rod and the cradle, and in order, a crank journal, a cross-shaped rotary locking arm and a piston cylinder in which the push rod is indirectly connected to the upper plate. The purpose is to provide a four-stroke engine without crankshaft and air valve, which can use gasoline or diesel oil by determining the internal height limit and having various compression ratios in the cylinder.

Based on the foregoing object, the four-stroke engine of the present invention having no crankshaft and no air valve includes a base, an air supply / exhaust valve, a cradle, a drive device set, and an upper plate.

Among them, the gear set provides control of the rotational speed ratio value between the crank journal or the cross-shaped rotational locking arm and the air supply / exhaust valve, and the rotational speed ratio is ≧ 2.

When the piston, push rod and air supply / exhaust valve reciprocate by driving the piston, the air supply / exhaust valve drives and rotates the cross-shaped rotary rocking arm, gear set, and connecting rod indirectly via the push rod. The intake / exhaust valve continuously operates the strokes of intake, compression, combustion, and exhaust, and performs the circulation operation by the four strokes of intake, compression, combustion, and exhaust of the engine.

Reference is made to FIGS. 4 to 6, a diagram showing air intake and exhaust stroke control by the intake and exhaust valves of the present invention, a front view of the engine operation according to FIG. 4, and a side view of the engine operation according to FIG. As can be seen from FIG. 4, when the engine of the present invention starts operation, the air inlet 20 and the air outlet 21 of the air supply / exhaust valve 2 are respectively connected to the air supply / exhaust port 12 of the cylinder 11 and the air supply / exhaust port 12 ′ of the cylinder 11 ′. The facing air passes through the air input hole 13 of the base 1, the air inlet / outlet of the air supply / exhaust valve 2 and the air supply / exhaust port 12 of the cylinder 11, and enters the inside of the cylinder 11. Then, the air is discharged through the air outlet 21 of the air supply / exhaust valve 2, the air supply / exhaust port 12 ′ of the cylinder 11 ′ and the air exhaust hole 14 of the base 1. The cylinder 11 'can be evacuated.

Reference is made to FIGS. 5A, 5B and 6, a front view of the engine operation according to FIG. 4, and a side view of the engine operation according to FIG. As is apparent from the figure, air is sent into the cylinder 11 through the air supply / exhaust port 12 of the cylinder 11, and the air sequentially pushes the piston 31 and the push rod 30 inside the cylinder 11 upward, while the cylinder 11 ' The internal air is discharged from the air supply / exhaust port 12 ′ of the cylinder 11 ′, and the piston 31 ′ and the push rod 30 ′ are pushed downward in the cylinder 11 ′. Among them, the reason why the piston 31, the push rod 30, the piston 31 ', and the push rod 30' can reciprocate up and down inside the cylinders 11 and 11 'is mainly the piston 31, the push rod 30, When the piston 31 ′ and the push rod 30 ′ are extruded or retracted inside the cylinders 11, 11 ′, the air inside the cylinders 11, 11 ′ located above the pistons 31, 31 ′ respectively passes through the holes 160. , 160 ′, the piston 31, the push rod 30, the piston 31 ′, and the push rod 30 ′ are vertically moved into the cylinders 11, 11 ′ by discharge or suction. As a result, the support shaft 321 connected to the push rod 30 reciprocates in the receiving space 3201 in an inward and outward direction, while the support shaft 321 ′ connected to the push rod 30 ′ The reciprocating motion is carried out in the accommodation space 3201 ′ inward and outward in order through the push rod 30 ′. Among them, the support shafts 321 and 321 ′ can reciprocate in the receiving spaces 3201 and 3201 ′, respectively. The main reason is that the support shafts 321 and 321 ′ are accommodated when they are extruded or retracted inside the receiving spaces 3201 and 3201 ′, respectively. Air inside the spaces 3201 and 3201 ′ is discharged or sucked through the vent holes 3202 and 3202 ′, respectively, and the support shafts 321 and 321 ′ can reciprocate inside the housing spaces 3201 and 3201 ′, respectively. Further, the support shafts 321 and 321 ′ reciprocate in the accommodating spaces 3201 and 3201 ′, respectively, and at the same time, the first guide rod 323 provided in the tube body 320 has the first roller bearing 333 of the first inclined rod 332 provided in the crank journal 33. Therefore, the first guide bar 323 rotates counterclockwise in conjunction with the first inclined bar 332, the horizontal bar 331, and the vertical bar 330 to form rotational energy.

When the first guide rod 323 rotates, the second guide rod 324 corresponding to the first guide rod 323 and connected to the lower end of the tube body 320 also rotates counterclockwise correspondingly to the first guide rod 323, The driving gear 345 is rotated in the counterclockwise direction by interlocking with the driving gear 345 at the end of the second inclined rod 347 connected via the two-roller bearing 348, so that the driving gear 345 sequentially moves in the order of the upper gear 342, the lower gear 343, The rotating shaft 344 ′ rotating simultaneously with the operating gear 346 and rotating simultaneously with the operating gear 346 rotates counterclockwise in conjunction with the connecting rod 22 of the air supply / exhaust valve 2.

As can be seen from the above, the supply / exhaust valve 2 is operated upward and downward simultaneously with the intake and exhaust strokes, and the connecting rods 30 and 30 ′ are oscillated in conjunction with the cross-shaped rotary locking arm 32 and rotated to the crank journal 33. By forming the energy and operating the gear set 34 to drive the connecting rod 22 connected to the air supply / exhaust valve 2, the air supply / exhaust valve 2 can rotate counterclockwise simultaneously with the intake and exhaust strokes.

When the push rods 30 and 30 'are pushed upward and downward respectively, no lateral force is generated, and the pistons 31 and 31' and the cylinders 11 and 11 'are completely prevented from touching each other, thereby extending the service life of the engine. it can.

Reference is made to FIGS. 7 and 8, a diagram showing cylinder compression and intake stroke control by the intake and exhaust valves of the present invention, and a front view of engine operation according to FIG. After the cylinders 11 and 11 ′ complete the intake and exhaust strokes respectively, the air supply / exhaust valve 2 continues to rotate in the counterclockwise direction, and the rotation mode of the air supply / exhaust valve 2 is mainly shown in FIG. The “supply / exhaust port 12” communicates with the air inlet 20 of the supply / exhaust valve 2 and feeds air into the cylinder 11 ′, while the supply / exhaust port 12 of the cylinder 11 is blocked by the outer wall of the supply / exhaust valve 2. Therefore, the sealing mode of the cylinder 11 is formed.

As shown in FIG. 8, after the air enters the cylinder 11 ′ through the air supply / exhaust port 12 ′ of the cylinder 11 ′, the air moves in order, and the piston 31 ′ and the push rod 30 ′ inside the cylinder 11 ′ At the same time, the air supply / exhaust port 12 ′ of the cylinder 11 corresponding to the cylinder 11 ′ is restricted by the outer wall of the air supply / exhaust valve 2, thus forming a sealed mode. The piston 31 and the push rod 30 inside the cylinder 11 The air inside the cylinder 11 is compressed downward, and the push rods 30 'and 30 are pushed upward and downward respectively. At the same time, the support shaft 321 connected to the push rod 30 moves inward and outward to accommodate the receiving space 3201. The support shaft 321 ′ connected to the push rod 30 ′ moves inward and outward through the push rod 30 ′ and moves inward and outward inside the accommodation space 3201 ′. Exercise to. Further, the support shafts 321 and 321 ′ reciprocate inside the accommodating spaces 3201 and 3201 ′, respectively, and the first guide rod 323 provided in the tube body 320 also rotates the crank journal 33 together. Since the interlocking method is the same as described above, description thereof is omitted here.

As described above, the rotation of the first guide rod 323 causes the cruciform rotary rocking arm 32 that swings to follow, and simultaneously, the gear set 34 and the air supply / exhaust valve 2 are interlocked together, thereby the cylinder 11 ′. , 11 perform the intake and compression strokes respectively, the supply / exhaust valve 2 also rotates counterclockwise, and the drive system of the gear set 34 and the supply / exhaust valve 2 by the cross-shaped rotary locking arm 32 is the same as described above. Therefore, explanation here is omitted.

Reference is made to FIGS. 9 and 10, a diagram showing cylinder combustion and compression stroke control by the intake and exhaust valves of the present invention, and a front view of engine operation according to FIG. After the compression and intake strokes of the cylinders 11 and 11 'are completed, the supply / exhaust valve 2 continues to rotate in the counterclockwise direction. The rotation mode of the supply / exhaust valve 2 is mainly shown in FIG. Since the air supply / exhaust port 12 and the air supply / exhaust port 12 ′ of the cylinder 11 ′ are respectively blocked by the outer wall of the air supply / exhaust valve 2, the cylinders 11, 11 ′ are sealed.

Continuing, reference is made to FIG. 10, a diagram illustrating cylinder combustion and compression stroke control by the intake and exhaust valves of the present invention. Inside the cylinder 11, after the piston 31 is compressed with a predetermined stroke in the downward direction, the gasoline vapor is immediately injected directly into the cylinder 11, and the gasoline vapor mixed in the cylinder 11 is instantly ignited and burned. At the same time as the piston 31 and the push rod 30 are pushed upward by the cylinder 11, the piston 31 and the push rod 30 corresponding to the inside of the cylinders 11 and 11 'compress the air inside the cylinder 11' downward. As a result, the cruciform rotation locking arm 32 is swung upward and downward via the push rods 30 and 30 ′, respectively. The gear set 34 is driven, and the crank journal 33 changes the reciprocating motion to rotational motion to form rotational energy, while the gear set 34 interlocks the connecting rod 22 of the air supply / exhaust valve 2 and reverses the air supply / exhaust valve 2. Rotate 360 degrees clockwise. Since the interlocking method of the cross-shaped rotary locking arm 32 using the push rods 30 and 30 ′, the crank journal 33, the gear set 34, and the air supply / exhaust valve 2 is the same as described above, the description thereof is omitted here.

After each of the cylinders 11 and 11 ′ completes the combustion and compression strokes, the air supply / exhaust valve 2 continues to rotate in the counterclockwise direction. The rotation mode of the air supply / exhaust valve 2 is mainly shown in FIG. The air supply / exhaust port 12 is connected to the air outlet 21 of the air supply / exhaust valve 2 and the air output hole 14 of the base 1, while the air supply / exhaust port 12 ′ inside the cylinder 11 ′ is blocked by the outer wall of the air supply / exhaust valve 2. Therefore, the sealing mode of the cylinder 11 ′ is formed.

Continuing to refer to the front view of engine operation according to FIG. The exhaust gas after the explosion inside the cylinder 11 is exhausted in order through the air supply / exhaust port 12, the air outlet 21 of the air supply / exhaust valve 2 and the air outlet 14 of the base 1 (that is, the exhaust stroke). The push rod 30 is pushed downward inside the cylinder 11, while the piston 31 ′ inside the cylinder 11 ′ compresses air downward in a predetermined stroke, and then directly injects gasoline vapor inside the cylinder 11 ′. The gasoline vapor mixed inside the cylinder 11 ′ is ignited and burned instantaneously, and the piston 31 ′ and the push rod 30 ′ are pushed upward inside the cylinder 11 ′. As a result, the cross-shaped rotary locking arm 32 swings by being pushed downward and upward via the push rods 30 and 30 ', and the cross-shaped rotary locking arm 32 swings and the crank journal 33 and The gear set 34 is driven, and the crank journal 33 changes the reciprocating motion into rotational motion to form rotational energy. The gear set 34 interlocks with the connecting rod 22 connected to the air supply / exhaust valve 2, and turns the air supply / exhaust valve 2 counterclockwise. Rotate 360 degrees in the direction.
