Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary engine having an intake / exhaust sluice valve and a C-shaped, freely rotatable, compression combustion chamber and a rotor having a chevron that rotates in a rotor housing.

[0002]

2. Description of the Related Art Many automobiles manufactured at present employ a so-called reciprocating engine, in which a piston is moved up and down by the explosive force of an air-fuel mixture and its reciprocating motion is converted into rotary motion by a crankshaft. In order to increase the output of this engine, there is no other way than increasing the engine size or increasing the rotation speed, but there is a limit to the speed at which the piston moves up and down, so in order to solve this problem, the rotary engine It has been developed and adopted in some automobiles, and has been improved so far.Today, the current rotary engine forms the inner peripheral surface of the rotor housing into an eyebrow shape and also has a rice ball-shaped rotor. Is characterized by rotating along the inner surface.

[0003]

As described above, in the rotary engine, since the inner peripheral surface of the rotor housing has to be formed into a cocoon shape, there is a drawback in manufacturing, and the manufacturing tends to be complicated. There was a drawback. In view of the above-mentioned conventional problems, the present invention can perform smooth acceleration from a low speed range to a high speed range without lowering the output at high speed rotation, has a small vibration and noise, and has the same output. The present invention provides a rotary engine that can be made smaller and lighter than the reciprocating engine described above and can be easily manufactured. Also, since the rotor directly contacts the outside air, it seems possible to use a ceramic rotary engine that does not require cooling water.

[0004]

[Means for Solving the Problems] To achieve the above object,
The engine according to the present invention is provided with a rotor (2) provided with a chevron on one side inside a circular rotor housing (1) in association with an output shaft, and a tip is provided on one side of the rotor housing (1). By contacting the outer peripheral edge of the rotor (2) and inserting and removing the intake / exhaust sluice valve (7) freely,
An intake port (8) and an exhaust port (9) are provided, and a rotor housing (3) is provided on the other side of which the tip is in contact with the outer peripheral edge of the rotor (2) and is rotatable, and the compression combustion chamber (10) is provided. The ignition plaque (11) is provided on the.

[0005]

Since the present invention is configured as described above, the angle (6) of the rotor (2) passes through the position of the intake port (9), so that the intake port is rotated as the rotor (2) rotates. The air-fuel mixture sucked into the rotor housing (1) from (9) is a rotor housing (3) that freely rotates with the rotor (2) as shown in the first drawing, and an inner surface of the rotor housing (1). It is confined in the compression combustion chamber (10) surrounded by, and the volume of this compression chamber (a) gradually decreases as the rotor (2) rotates, and the air-fuel mixture enters the compression combustion chamber (10). Rotor (2)
At the same time when the chevron (6) comes into contact, the freely rotatable C-shaped rotor housing (3) rotates while accumulating the air-fuel mixture, and the center of the freely rotatable C-shaped rotor housing (3) is set to the rotor ( Simultaneously with the passage of the chevron (6) of 2), the mixture is ignited and exploded by the spark of the spark plug (11) and pressurizes the inside of the compression combustion chamber (10), so that the rotor rotates and the expanded combustion gas Is discharged from the exhaust port (8) as the rotor (2) rotates, and the same process as above is repeated.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. Figure (1) is a combination of a large circle (15), a small circular arc (16), and a C-shaped free-rotating combustion chamber (10), with the same large circular center of the rotor housing (1). A rotor (2) with a chevron attached to a perfect circle is provided in association with the output shaft (5). An intake / exhaust sluice valve (7) is sandwiched on one side, and an intake port (9) is on the upper side and exhaust is on the lower side. A mouth (8) is provided. The sluice valve (7) engages with the guide hole (13) provided in the rotor housing (1), and the upper part of the guide hole (13) is pressed by a spring toward the center of the rotor (2). The guide hole (13) is constantly applied with an appropriate pressure so that when the rotor chevron (6) comes into contact with the rotor chevron (6), the outer peripheral edge of the rotor chevron (6) is brought into contact with the rotor chevron (6) to freely move back and forth. (3) is a C-shaped rotatable rotor housing (3), one side of which is constantly in contact with the outer peripheral edge of the rotor (2), and at the same time the chevron (6) of the rotor (2) is in contact with the C-shaped rotation. Both sides of the free rotor housing (3) are set to rotate while contacting the chevron of the rotor (2).

[0007]

As described above, the present invention directly converts the explosive force of the air-fuel mixture into the rotational movement of the output shaft without using the crank mechanism, so that the output at the time of high speed rotation does not decrease. It can perform smooth acceleration from low speed to high speed, has less vibration and noise, and is smaller and lighter than a reciprocating engine of the same output. Similarly, unlike the one in which the inner peripheral surface of the rotor housing is formed into a cocoon shape, it is easy to manufacture because it uses a circular rotor housing. It also has the feature that the control mechanism for rotating it can be omitted.
