Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine rotated by a piston that performs circular motion, namely a rotary piston engine (hereinafter referred to simply as a rotary engine).

The majority of engines currently in practical use are 1. (i!) The piston is reciprocated like a positioning piece by one 4 shots in one revolution (one 'revolution in 2 revolutions in a 41 cycle engine), and the reciprocating M movement is transmitted to the connecting rod and crank. It is a reciprocating engine that converts 11 to 11 (movement).

In a reciprocating engine, each time the piston engages in reciprocation, the
If the multi-cylinder type is used, the volume of 1L will be proportional to the number of cylinders. In addition, gas exchange in each process of suction, compression, 111r tension, and exhaust 1 is inefficient in a 2-stroke engine, and although it can be done efficiently in a 1-stroke engine, it has a valve mechanism that is difficult to maintain. K own rank mechanism and Taki 1
If it is made into a cylinder, the mechanical loss of 4↑4 is large due to the W-bamboo connection and the Q-lance mechanism, resulting in a very poor energy efficiency.

In addition, during continuous rotation, the rapid opening and closing operation of the valve may cause surging or tearing, so it is difficult to maintain high speed rotation and high output.Therefore, the above I am satisfied with the reciprocating engine, which has such drawbacks, but the rotary engine, which was developed to link the piston itself once per rotation and extract the rotational force as output as it is, is now available in both the world and the world. Many engines have been proposed in the past, and their types are diverse, including eccentric rotary engines, cat-and-mouse engines, multi-rotor engines, and rotating block engines.

Of these, several persimmons have been successful, although they are still in the experimental stage, and the W
Ankel Engine's answer is...high from 1! The '+ value receiver' is currently being put into practical use, and it takes advantage of the advantages of not requiring the bell mechanism unique to rotary engines and of transmitting the explosive force to the width of the rotating part of the compensating piston, reducing the number of parts. This makes it possible to reduce the size and weight of the motor, and it also exhibits excellent effects such as low vibration, high speed rotation, and high output.

However, in order to achieve tangential rotational interlocking with 1, the history of the Wankθ10-Tali engine, which involves complicated volumetric changes in the trochoidal curve combustion chamber due to eccentrically interlocking pistons, is still relatively new, so it has been cultivated through actual tests for k years. However, the combustion rate of the Japanese commercial engine changed dramatically, and the difference in technology was clearly evident, rather than the ratio of a reciprocating engine with a crank mechanism.
The amount of fuel consumption etc. is increased by +Ll.

In addition, two sets of rotary pistons (hereinafter simply referred to as piston sets) of -z1 are provided, which rotate simultaneously while maintaining a 180° phase relationship with il within the annular cylinder, and only one piston set is rotated unequally. The 1L piston set rotates in equal rotation while using an unequal rotation power transmission mechanism (Kauer

) has a good result; however, it has many problems with inertia during heavy rotation, and has not been put to practical use.

Therefore, this idea revolved around the above facts and was thoroughly researched.
By incorporating the numerous methods and +11 points of the reciprocating engine, which can now be said to have reached the stage of perfection, into the cat-and-mouse engine, the advantages of the rotary engine were exploited, and the valves (with no < L, small 114 volume) were incorporated into the cat-and-mouse engine. In order to provide a rotary engine with low movement and fuel consumption, high speed rotation, and crystal output with high energy efficiency, and to put it into practical use, we have carried out various experiments and research. It was finally completed as a result of repeated efforts,
First, the gist of this invention is as follows.

That is, the present invention includes a rotor having a pair of pistons which are diagonally opposed to each other in an annular cylinder having a circular orbit, and which rotate once around the center. When the planetary gear mechanism is rotated in the direction opposite to the revolution direction, a planetary gear mechanism is installed, and the crank provided on the planetary south wheel of the planetary gear mechanism and the rotor of each rotor are installed. This rotary engine is configured to link and connect the planetary gears and transmit the rotation of the planetary gears to the output shaft.

The gist of this invention will be further clarified, and one embodiment of the rotary engine according to IJ, 11K will be described in detail with reference to the drawings along with an explanation of its operating principle. It is as follows.

First, let's make the operating principle υ11 easier to understand < + rf line
In other words, in FIG. 1, pistons B and C that move horizontally within cylinder A are connected to crank mechanism F by links D and E, respectively.

Further, the crank mechanism F is installed coaxially with the pinion gear G, and is in mesh with the pinion gear G rack H.

When an explosion is caused between the pistons E and O in the cylinder A, the pressure from the dust causes the pistons ``3'' and ``C'' to operate, and the operation of the pistons B and O is coupled to the crank F and the crank F through links D5E, respectively. Attempts are made to rotate the pinion gear G. (Fig. 2) However, since the pinion gear G is meshed with the rack H, in order to rotate, it must also perform simultaneous [# movement, and the piston B moves as the link D moves. The piston O, which moves to the left and is connected to the link E, is kept in a stopped state in a phase 1i relationship with the cylinder A.

(Fig. 8) By applying the above lGt principle, a cat-and-mouse engine with phase n-inconstant speed interlocking in which each piston moves forward and stops repeatedly is theoretically possible. If the car is simply replaced with an idler gear, the rotation of the star gear, that is, the crank, will rotate at high speed due to the sum of its rotation and revolution, and as mentioned above, the problem of single-penetration force will arise, making it impossible to put it into practical use. Therefore, this point has been fully taken into consideration in the engine of the present invention.

Next, 91 concrete example)+b will be explained, but it goes without saying that the present invention is not limited to the following examples.

That is, 1 is a housing of a rotary engine according to the present invention, and the housing 1 forms an annular cylinder (hereinafter simply referred to as a cylinder) 11 having a circular orbit.
The cylinder 11 is provided with an intake hole 12 and an exhaust hole 13, respectively, and has an ignition plug 14.

Further, 3 is an output shaft, and 4 is a fixed gear formed integrally with the housing 1. At the outer edge of the fixed gear 4, there are a transmission gear 41 that rotates around the fixed gear 4 as a planet, and a fixed gear 4. A planetary gear 42 having a tooth ratio of 2 to 1 and planetarily interlocking the circumference ν4j of the two fixed cities extends around the outer periphery of the output shaft 3. The gears 4, 41, and 42 are arranged in a direct expansion row through a constant arm 31 with the screens of each gear meshing with each other.

In Fig. 4, an output of 1l is generated by a starter motor (not shown).
III 13 is rotated counterclockwise, an explosion occurs in the combustion chamber 11a due to the ignition of the spark plug 14, and the expansion force of the explosion causes both pistons 2a and 2b to move in opposite directions.

However, both pistons 2a and 2b have rotors 21 and 22, respectively.
The crankshaft 5 is connected to the crankshaft 5 by a link 7.7a, and the crankshaft 5 rotates around the fixed wheels 4 through a transmission gear 41 and a planetary gear 42 in a direction opposite to the revolution direction at the same rotation speed. Since it rotates on its own axis, the crankshaft 5 is guided by the rotation imparted by the starter motor in Fig. 2, and rotates clockwise and revolves counterclockwise, and the piston 2a-
The piston 2b moves in the opposite direction, while the piston 2b remains stationary within the cylinder.

Similarly, each master stroke of qζ is performed between &, so that one additional stroke is applied for every 11r11 rotation of the output shaft 3.

14- Considering the rotary engine as described above, this rotary engine is mechanically simple, but provides ideal interlocking to the pistons in a cat and mouse engine, and operates smoothly, to a degree that is incomparable to a reciprocating engine. It has many advantages such as the characteristics of an excellent rotary engine, such as small size, light weight, high speed rotation, high output, and low vibration, and by eliminating the valve mechanism, the number of parts can be reduced and it can be provided at a low price. Well, it has the following excellent effects.

(υ The rotation of the a star gear is adjusted to the same number of rotations as the output shaft by adopting a transmission gear and selecting a precise gear ratio,
The inertia force reduces the stress on the crankshaft, making it more durable.

(2) Since the cylinder and piston are similar to those of a reciprocating engine, it can be easily realized by using the familiar technology of the Reciprocating Engine along with the crank mechanism.

-15- (8) The crankshaft is provided with a free wheel, a flywheel and a flywheel at both ends, and the l11σ side is supported by a fixed arm, and the rotation of the crank arm is carried out by the rotor in the middle, so balance is maintained. It is very stable, and has 4 shots per 11 m rotation, which is equivalent to 8 cylinders when converted to a 4-stroke reciprocating engine. It will become a part of history.
As shown in Figure 10, by installing 6 pistons in the same cylinder, [61-Improved performance with cylinder volume,
Like an electric motor, you can get really smooth rotation even at low speeds of 1141 rpm.

Note that although the rotary engine in the example described in Section 11 is of vertical type, it may also be used horizontally or tilted when mounted on a vehicle. Separate the planetary gears, etc. from the rotor and piston as shown in Figure 11.
The shape and structure of the crankshaft, etc. may be changed as appropriate within the scope of achieving the above-mentioned objects and effects of the present invention, such as changing the overall shape of the engine as appropriate depending on the purpose of use. Needless to say, it is good that it is established.
