[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine using two rotors rotating at a constant speed and a variable speed.

[0002]

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact engine while minimizing the loss of generated force and at the same time reducing the generated vibration.

[0004]

SUMMARY OF THE INVENTION The present invention provides a means for obtaining high-efficiency rotational power by suppressing the generated vibration as much as possible by providing two coaxially rotating rotors in a combustion space. .

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. As shown in the front view in FIG. 1, the apparatus according to the present invention is provided with two rotors having the same rotation axis inside a cylindrical cylinder, one rotor rotates at a constant speed, and the other rotor rotates at a variable speed. The resulting variable clearance is adapted to be applied to the combustion cycle of the engine.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a cylindrical cylinder having a vent for intake and exhaust on its outer peripheral surface, which is integrally formed with a gear mechanism (gear box) for controlling a variable speed rotating rotor 2.

[0007] Reference numeral 2 denotes a variable-speed rotating rotor, which realizes an engine combustion cycle of intake, compression, explosion, and exhaust through a vent hole provided outside the cylindrical cylinder 1 by utilizing a gap with the preceding constant-speed rotating rotor 6. I do.

Reference numeral 3 indicates that after the preceding constant-speed rotor 6 completes the compression stroke and ignites and explodes at the position of the spark plug 4, the succeeding speed-changing rotor 2 stops rotating in the reverse direction due to the explosion. And a simple mechanism such as a reverse lock type is desirable.

Reference numeral 5 denotes a position for the compressed mixed gas immediately before the ignition explosion when the preceding constant-speed rotating rotor 6 and the succeeding variable-speed rotating rotor 2 coincide at an opening angle of 0 degree at the position of the spark plug 4. This is a space of a fixed volume.

This space must form a volume calculated so that the compression ratio of the gas mixture immediately before the ignition explosion is optimized.

As shown in FIG. 2, the apparatus of the present invention has a gear mechanism (gear box) for controlling a variable speed rotary rotor directly connected to a cylinder portion including two rotary rotors.

10, 11, and 12 are small diameter, medium diameter,
A gear of the same type and the same structure constituted by a large-diameter three-stage gear, in which only portions necessary for rotation control are carved, and only the three-stage gear 11 arranged at the center is another three-stage gear. 10 and 12 are combined in the opposite direction.

3 to 5, a description will be given of a mechanism in which one of the rotors in the cylinder is rotated at a variable speed by the combined three-step gear.

First, at the time shown in FIG. 3, the constant-speed rotating rotor 6 and the variable-speed rotating rotor 2 are located at the ignition point, and their opening angles are 0 degrees.

Due to the ignition explosion, the constant-speed rotating rotor 6 starts to rotate clockwise. At this moment, a force that causes the variable-speed rotating rotor 2 to rotate in the counterclockwise direction is generated. A reverse rotation prevention stopper 3 for preventing reverse rotation must be provided.

The gears 10, 11,
Reference numeral 12 denotes large-diameter gears 10a, 11a, 12a, medium-diameter gears 10b, 11b, 12b, and small-diameter gears 10c, 11 respectively.
The large gear 11a is in mesh with the small gears 10c and 12c on both sides since the gear 11 located at the center is assembled upside down.

In this embodiment, the ratio of the diameters of the respective gears is defined as a large diameter a: small diameter c = 2.5: 1, a medium diameter b: small diameter c = 1.7.
It represents 5: 1. Note that the diameter ratio is not limited to this.

Each gear is designed such that teeth are formed only in necessary portions in order to achieve a timing of rotation, and a rotation speed is changed depending on a meshing position.

The constant-speed rotor 6 that has started to rotate clockwise opens with the variable-speed rotating rotor 2 whose rotation angle has been reduced by a gear mechanism (gear box) formed by a combination of three-stage gears having the above-mentioned diameter ratio. When the angle is enlarged and the constant-speed rotating rotor 6 rotates to 110 degrees, the variable-speed rotating rotor 2 rotates to 44 degrees to maximize the opening angle of both rotors at 66 degrees, and then gradually rotates two sheets. Narrow the opening angle between the rotors.

At the time when the rotor is rotated by 180 degrees, the succeeding variable-speed rotating rotor 2 and the preceding constant-speed rotating rotor 6 coincide with each other at an opening angle of 0 degree, and the exhaust stroke is completed.

Subsequently, the constant-speed rotating rotor 6 starts rotating clockwise ahead of time, and performs suction while gradually increasing the opening angle with the variable-speed rotating rotor 2 that gradually follows again.

When the opening angle again exceeds the maximum point of 66 degrees, the intake stroke is completed, and the two rotating rotors perform the compression stroke while reducing the opening angle.
At that time, compression is completed and ignition explosion occurs.

[0023]

The present invention is configured as described above and has the following effects.

Since the two rotors are arranged coaxially, vibration generated by rotation is small, and energy loss is reduced, so that the generated force can be used efficiently.

Further, by providing a vent hole in the outer peripheral portion of the cylinder, there is an advantage that the structure can be simplified without requiring a complicated valve mechanism.

Since the entire engine structure can be made compact, it can be used in a hybrid system in combination with an electric motor.
