Though the rotor is moved anomalously, a crankshaft and a slide bearing allow smooth rotation to get a motive power.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention is a new type of rotary engine having a basic shape of a composite circle, and can also be used as a pump. The basic shape of the rotary engine shown in "Claim 1" is such that a linear shape that inscribes three small circles and three great circles centered on each point of an equilateral triangle as shown in FIG. An internal combustion engine and a pump using a change in a working chamber (1) caused by moving a rotor (2) based on the same small circle and great circle as a reference, about each point of an equilateral triangle, as a housing (3). It works as The change in the working chamber (1) due to the movement of the rotor (2) is shown in Fig. 8
This is as shown in the operation diagram of FIG. The relationship between an equilateral triangle and a small circle and a great circle is as follows (see FIG. 1). Let one side of an equilateral triangle be L Let the radius of a small circle be R1 Let the radius of a great circle be R2 R2 = L + R1 Rotor width = R1 + R2

The operation of the rotor (2) rotates about each point of the equilateral triangle, and the rotation angle when the rotor (2) moves about one point of the equilateral triangle is 60 degrees, and then another angle. This is an anomalous motion in which a rotation of 60 degrees is made around a point of an equilateral triangle, and then a rotation is made around another triangle point. The state of rotation of the rotor (2) is as shown in the operation diagrams of FIGS. 8 and 9. A method of extracting power from the irregular movement of the rotor (2) according to claim 2 is as follows. 3) Center the rotor (2) with the crankshaft (1).
0), and the displacement of the center distance between the rotor housing (3) and the rotor (2), which occurs when the rotor (2) rotates, is applied to the shaft on the rotor side of the crankshaft (3) in the width direction of the rotor (2). Is moved by the slide bearing (11) to absorb the displacement between the shafts and transmit the power. When the rotor (2) moves, the rotor (2) and the crankshaft (10) and the slide bearing (11)
8 and FIG. 9, the crankshaft (10) makes four rotations while the rotor (2) makes one rotation. The structures of the rotor (2) and the crankshaft (10) are as shown in the perspective views of FIGS. 4 and 5 and the exploded view of FIG.

[0003] Claim 3 is an example in which the basic structure of claim 1 is used as an internal combustion engine. One example of a structure used as an internal combustion engine is as shown in FIGS. 2 to 7, in which a rotor housing (3) has a spark plug (4) at one place and a rotary valve for intake and exhaust at one place. (5), a rotary valve (6) for an intake and pressurized tank is provided in one place, a hollow serving as a combustion chamber (13) is provided in a rotor (2), and rotation of the rotor (2) is controlled by a crankshaft (10). ) And the slide bearing (11)
It is a structure to take out power. Operation as an internal combustion engine
As shown in FIGS. 8 and 9, the rotor (2) is rotated to perform seven strokes of “intake → pressurization of intake → intake → intake of pressurized intake → compression → explosion → exhaust”. Things. Also, while the rotor (2) makes one rotation, the rotor (2)
It performs seven strokes on one side and performs one explosion, and performs the same operation on the other side, and performs two explosions on both sides. In the engine of the present invention, the volume of the rotor (2) changes three times on one side of the rotor (2) during one rotation. Therefore, in the case of a four-cycle internal combustion engine, it is necessary to change the ignition position. Therefore, the intake is performed twice and the amount of intake is increased, and the ignition is performed at the same position. One intake is shown in FIG. As shown, a pressurized tank (7) is provided and temporarily stocked here.
At the time of the second intake, the intake air of the pressurized tank (7) was press-fitted into the working chamber (1) in the latter half to increase the intake air amount, thereby increasing the combustion efficiency.

Since the rotary valves (5) and (6) are located away from the high-pressure section generated during the explosion or compression in the working chamber (1), the pressure loss of the valve section is small. Although a rotary valve is used for this purpose, a piston-type valve of another type may be used.

[0005] A "claim 4" is used in order to make the operation of the seven strokes of the "claim 3" a general four-stroke operation.
As shown by "0", the ignition device (4), the intake air (8), and the exhaust equipment (9) are provided at three places of the rotor housing (3), respectively, while the rotor (2) makes one rotation. On one side, perform four steps of “intake → compression → explosion → exhaust”.
Performed 5 times, and the same operation was performed on the opposite side of the rotor (2), and the structure was such that the rotor (2) exploded three times during one revolution, and was a high-power engine. It is.

In the structure of claim 3 and claim 4, the intake air is basically a mixture of gasoline and air in the case of a gasoline engine or the like, but is replaced with a spark plug (4) in the case of a diesel engine or the like. Can be used by providing a fuel injection facility.

[0007] Claim 5 uses the basic structure of Claim 1 to make the pump work, and as shown in Fig. 11, the rotor housing (3) has three check points. Providing a valved suction (15) and discharge valve (16),
Utilizing changes in the working chamber (1) that occur when the rotor (2) rotates, it is used as a pump and a compressor.

The working chamber is hermetically sealed by a seal (12) provided on the rotor. The seal (12) on the rotor housing side is structurally different from the basic shape described in “Claim 1”.
Because it is always perpendicular to the tangent circle, multiple seals (12)
Can be installed, and the number of installations can be determined according to the purpose.
