Abstract

PURPOSE:To improve the efficiency of an internal combustion engine, by a method wherein pistons are attached in an annular cylinder formed in a manner that rotors, brought into contact with each other in a condition to be positioned facing each other, are placed in bodies. CONSTITUTION:Rotors 1L and 1R, brought into contact with each other in a manner to be positioned facing each other, are placed in bodies 2-4. Pistons A1 and A2, having the same shape in cross section as that of an annular cylinder C, are placed in the annular cylinder C and attached to the rotor 1L in a reverse position to each other in an axial direction. Pistons B1 and B2 are attached on a rotor 1R in a similar manner described above. The half portion of the piston slides over its mating rotor. The rotrs 1L and 1R are rotated as a distance between the pistons is increased and decreased in a condition in that the rotors 1L and 1R are both rotated in the same direction. This enables improvement of the efficiency of an internal combustion engine.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is as shown in FIGS. 1 and 4. Main body 2, 3,
The space created by placing the rotors 1L, 1R facing each other and in contact with each other in the hollow cylinder formed by 4 is ring-shaped, and this ring-shaped space is used as the cylinder C, Segment-shaped pistons A1 and A2 having the same cross section as the ring-shaped cylinder C are attached to the rotor 1L at opposite positions in the radial direction.

Similarly, the pistons B1 and B2 are attached to the rotor 1R (the movement of the pistons A1, A2, B1, and B2 is different from reciprocating motion, but for convenience, they will be called pistons).

Each piston half slides over a mating rotor.

Then, the ring-shaped cylinder C has rotors 1L and 1R inside.
, while rotating in the same direction, the distance A1B1 between each piston
, B1A2, A2B2, B2A1, alternately,
It is a rotating engine that rotates while repeatedly expanding and compressing each piston. (Figure 1 shows the rotors 1L and 1R without the main bodies 2, 3, and 4, the pistons A1 and A2 installed on the rotors, and the piston B1,
B2, is a perspective view).

Its driving method is hypotrochoid.
, when the ratio of the radius of the fixed circle to the moving circle is 2:1, the fixed point on the radius on the moving circle or its extension moves around one diameter of the fixed circle. Let me explain.

In Fig. 2, the center of the moving circle that rotates in contact with the fixed circle d whose center is 0 is M, the radius of the fixed circle is a, the radius of the moving circle is b,
shall be.

The locus PP' drawn by the point P on the dynamic circle is the hypo
cycloid).

Now, if we consider a rectangular coordinate axis whose origin is the center 0 of a fixed circle, then the rectangular coordinates (x, y) of the curve drawn by a fixed point on the moving circle are t, the center M of the moving circle, and the origin 0. The angle formed when the line connecting , intersects the x-axis is the angle measured by the arc method.

Now, if the radius of the moving circle is half the radius of the fixed circle, that is, b=a/2, then x=acost y=0, so when the moving circle makes one revolution, the fixed point on the moving circle is the same as the fixed circle. Reciprocate the diameter.

Further, since a fixed point on the opposite moving circle having the same diameter as this fixed point has x=0 y=asint, this point also reciprocates along the diameter of the fixed circle.

That is, when the radius ratio of the fixed circle and the dynamic circle is 2:1, if one point reciprocates along the x-axis at both ends of the diameter of the dynamic circle, the other point reciprocates along the y-axis.

At this time, the center N of the moving circle is (the center of the moving circle when the radius of the moving circle is half the radius of the fixed circle is N), and the center of the fixed circle is 0.
, the moving circle itself rotates once around the center N in the opposite direction.

This movement is demonstrated using planetary gears. Furthermore, in order to place the shaft in the center, the mechanism shown in FIG.
, and set the gear ratio of gear 12 and planetary gear 13 to 2.
:1.

If the arm 14 is rotated once clockwise while the gear 12 is rotated twice clockwise, the planetary gear 13 is rotated counterclockwise once around N. That is, this planetary gear mechanism has a fixed circle d with a radius of 20N, a moving circle l with a radius of ON, which rotates in contact with each other without slipping,
The movement is the same as (the radius ratio is 2:1, the relationship between a fixed circle and a moving circle).

Its structure will be explained with reference to FIG.

(Due to the large number of parts, the 1L rotor rotates in contact with each other.
For gears that connect to rotor 1R, add an L after the number, and for gears that connect to rotor 1R, add an R after the number.If the number is only the number and L and R are omitted, it is common to both. ).

In Fig. 4, the rotor 1L is installed on top of the piston A1.
, A2, are on the cut plane. Its cross section is the same as that of the ring-shaped cylinder C, and its left half is the rotor 1.
This shows that it is in contact with R.

Rotor 1L is connected to gear 5L, and gear 5L is connected to gear 5L.
, the rotor 1L is also rotated.

Similarly, when the gear 5R is rotated, the rotor 1R is also rotated.

Further, a planetary gear 13 meshed with a gear 12 attached to the central shaft 11 is attached to an arm 14 whose outer periphery is a gear by a shaft 15, and rotates around gears 1 and 2. . (Two planetary gears 13 are used in symmetrical positions).

The ratio of the number of teeth between the gear 12 and the planetary gear 13 is 2:1.

There are flanges 16L and 16R at both ends of the shaft 15,
The flanges 16L and 16R each have a sliding piece 1 in the opposite direction from the center of the shaft 15 (center N of the planetary gear 13).
Sliding pieces 10L and 1 to which 0L and 10R are attached
If the centers of 0R and 0R are respectively A0 and B0, then A0N=B0N. Then, the sliding pieces 10L, 10R fit into the sliding grooves 9L, 9R provided in the gears 8L, 8R, and slide in the radial direction.

For this purpose, the planetary gear 13 and the arm 14 are connected to the gear 12,
When the gears 8L and 8R rotate once around the center O, the gears 8L and 8R also rotate once in the same direction around the center O, although at unequal speeds.

If gears 8L and 8R turn, gears 7L and 7R, gear 6L,
Turn 6R and gears 5L and 5R to turn rotors 1L and 1R.

At this time, if gears 8L, 8R and gears 5L, 5R are set at the same rotation speed, the movement of gears 8L, 8R is directly transmitted to rotors 1L, 1R, and rotors 1L, 1R,
This appears as the movement of the upper pistons A1, A2 and pistons B1, B2.

The movement will be explained with reference to FIG.

If A0B0, is made slightly shorter than 20N, A0, B
0, is a hypotrochoid, then the rectangular coordinates (x, y) of A0, are x=(ON+N
A0)cost y=(ON-NA0)sint The rectangular coordinates (x, y) of B0 are expressed as x=(ON+NB0)cost y=(ON-NB0)sint.

That is, A0 moves around the x-axis, while B0 moves around the y-axis.

In the present invention, pistons A1, A2, pistons B1, B2
, both must be centered around the same axis.

Now, if we move pistons B1 and B2 around the x-axis, they move in the same way as B0, but if we turn them 90 degrees and move them, we can change the movement of pistons B1 and B2 around the x-axis. It can be turned into movement.

In FIG. 5, the center 0 of the gear 12, the planetary gear 13,
center N, sliding piece 10L, center A0, sliding piece 10R,
When the center B0 of is on the y-axis in a straight line, piston A1 is placed on the y-axis, and piston B1 is placed at a position rotated by 90 degrees, that is, on the x-axis, piston A1, piston B1, Both move around the x-axis.

Now, when the center N of the planetary gear 13 rotates to N', A0 rotates to A0', B0 rotates to BO', then it is located above OA0 (on the y-axis). The piston A1, which was in the
Piston B0, which was at the position rotated by 0° (on the x-axis), is O
Rotate to a position 90 degrees from B0'.

In other words, the movement of OA0 is the same as that of pistons A1, A2,
The movement at a position rotated 90 degrees from OB0 is the movement of pistons B1 and B2.

Figure 6 shows that one rotation of the center N of the planetary gear 13 around the center 0 is divided into 16 equal parts, and the respective OA0, OB0,
It shows the position of OB.

is written from the position rotated 90 degrees.

If the position of OA0 is expressed as a0a1a2...a15, and the position of OB0 is expressed as b0b1b2...b15, then (a0b0
), (a1b1), ...... (a15b15), each set indicates the position of OA0, OB0 at the same time,
This simultaneously means pistons A1, A2, pistons B1, B2
, indicates the position of .

Figure 7 shows the rotation of the planetary gear 13, center N, around the center 0, divided into 8 equal parts, and the sliding of the gear 12, center 0, the center N, of the planetary gear 13, every 1/8 rotation. It shows the movement of the center A0 of the piece 10L and the center B0 of the sliding piece 10R, which progress in the direction of the arrow.

At this time, the circumference is divided into four equal parts on the inside of the gear 12, and
The rotation of the gear is expressed by the movement of the numbers, indicating that when the gear 13 and the arm 14 rotate once, the gear 12 rotates twice.

Figure 8 shows the positions of pistons A1, A2, and pistons B1, B2 corresponding to the respective time points shown in Figure 7.The figure shows the OA0 when divided into 16 equal parts as shown in Figure 6. ,OB
The symbol for the position 0 is written.

As explained above and illustrated, when the center 0 of the gear 12, the center N of the planetary gear 13, and the centers A0 and B0 of the sliding pieces 10L and 10R are on a straight line, the pistons A1 and A2 and the piston B1 It can be seen that when the line connecting B2 forms a right angle, the distance between the pistons alternately increases and decreases during each rotation, repeating four times.

When using this as a suction/exhaust engine, as shown in Figure 9,
By providing four openings in the ring-shaped cylinder C, suction and discharge are performed in the direction of the arrow when turning clockwise.

When used as an internal combustion engine, as shown in Fig. 10, two openings are provided in the ring-shaped cylinder C. When the piston rotates clockwise, the upper half performs suction and compression, and the lower half performs suction and compression. explodes (expands) and exhausts air.

At this time, the line ON connecting the center 0 of the gear 12 and the center N of the planetary gear 13 is the center A of the sliding pieces 10L, 10R.
If the angle formed by the line A0B0 connecting 0 and B0 is set at position 20, which is slightly turned from when the angle is a right angle, a larger torque can be obtained more smoothly. This will be explained with reference to the second diagram from the left in the upper row of FIGS. 7 and 8.

ON and A0B0 are at a right angle, and if an explosion occurs between pistons A2 and B2 at this time, a force that tries to turn piston A2 to the left acts on piston B2, which causes it to turn to the right. This is the sliding piece 10 where the force that tries to do so is applied.
The same can be said for the centers A0 and B0 of L and 10R.

A force that tries to turn left is applied to A0, and a force that tries to turn right is applied to B0. These contradictory forces together turn the planetary gear 13 in the same direction (counterclockwise around N). , for ON and A0B0
It turns out that the position 20, which is slightly rotated from when the angles are at right angles, is sufficient.

As can be seen from the above description, the present invention has a simple structure consisting of a ring-shaped cylinder, a plane and a cylinder.

A large capacity can be obtained with a small cross-sectional area.

By appropriately selecting the length of the piston, the position and size of the intake and exhaust ports, it is possible to operate without using any valves.

When used as an internal combustion engine, the energy generated by the explosion is absorbed by the front and rear pistons, and the forces in different directions work together to turn them in the same direction, resulting in an efficient internal combustion engine. I can do it.
