DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cat-and-mouth type rotary engine and a cat-and-mouth type rotary fluid compressor or blower.

[0002]

2. Description of the Related Art Heretofore, all cat and mouth type rotary engines have used two sets of deformed gears. The explosive force received by the rotor head is transmitted to the separate gears attached to the two rotors, and the moment of the force resulting from the difference in the distance between the point of engagement with the other pair of gears meshing with them from the axis of the output shaft. By utilizing the difference, the output is extracted on the principle that the output shaft rotates in the direction in which the gear with the larger moment rotates. However, in the case of ordinary deformed gears, there is an engagement point where the magnitude of the moment of force is reversed with another set of gears in the middle of a cycle in which a certain rotor head receives the explosive force and rotates the output shaft, After this point, the gear on the side with the larger moment of force continues to rotate in the original direction of rotation due to inertia despite trying to rotate the output shaft with the opposite force, causing gear damage and severe wear. The Cat and Mouse type rotary engine could not be put to practical use.

[0003] A rotary engine of US Pat. No. 5,224,847 (later abandoned) eliminates this drawback. This is a cat-and-mouth type using gears designed so that the magnitude of the moment of force does not reverse with that of another set of gears in the middle of a cycle in which a certain rotor head receives the explosive force and rotates the output shaft Although it is a rotary engine, unfortunately, the gear was invented for a long time, and although many similar shapes have been patented, it is actually a gear that is not manufactured industrially. A mouse-type rotary engine has not been put to practical use.

Japanese Patent Application No. 04-212339 discloses a cat-and-mouth type rotary engine that does not use gears.
There is a method that uses a generator to extract power and temporarily converts explosive power to electricity,
Not only the mechanism becomes complicated and the device becomes large and heavy,
There is a defect that the loss of power transmission is large due to the conversion of the energy form.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-described problems of the conventional cat-and-mouth type rotary engine, and enables the following to be achieved, and a cat with a fluid compressor or a blower. An object of the present invention is to provide an and-mouth type rotary engine. It is another object of the present invention to provide a cat-and-mouth type rotary fluid compressor or blower that operates using external power while substantially maintaining the structure of the cat-and-mouth type rotary engine. (1) Smooth rotation without causing damage to parts or severe wear. (2) Convert energy into rotational force efficiently and reasonably. (3) A mechanism capable of using components that can be mass-produced industrially. (4) The structure is simplified and the overall bulk is reduced. (5) Special processing parts are not required, thereby lowering processing costs and improving productivity.

[0006]

For this reason, the cat-and-mouth type rotary engine of the present invention does not depend on the method of taking out the power by the difference in the force moment between the two sets of gears. On the other hand, grooves having partially different angles are engraved so as to surround the output shaft.
The difference in the magnitude of the component force in the rotating direction of the explosive force applied to the grooves of the two rotors is taken out via a rod, and the following structure is adopted to obtain the rotating force.

That is, the rotors (1) and (2) are disks and are provided with rotor heads (3) (5) and (4) at both ends in the radial direction.
The shaft holes (7) and (8) having (6) and having the same inner diameter are provided at the centers of both rotors without being eccentric. With the rotors facing each other, an output shaft (20) having a diameter substantially equal to the inner diameter of the shaft hole is inserted into the housing through both shaft holes. The two rotors are rotatable with each other as long as the rotor heads do not contact each other, and are also rotatable with respect to the output shaft. Each part is set to have a size rotatably abutting so that the donut-shaped hermetic chamber defined by the inner wall of the housing and the two rotors is further divided into four hermetic chambers by the four rotor heads, thereby maintaining airtightness. Attach necessary sealing materials to
An ignition device or a fuel injection device (1
7), one intake port (18) and one exhaust port (19). No intake or exhaust valves are required.

For the sake of convenience, the housing is divided into two parts on the right and left sides in a plane perpendicular to the output shaft, and a heart-shaped groove (15) that goes around the shaft hole (13) on the inner surface of the left piece (11) of the housing. ), And the rotor (1) facing the groove.
Is provided with a toroidal groove (9) that goes around the shaft hole (7). The direction of the tomogram is defined by drawing an imaginary line extending in the radial direction from the output shaft when the rotor (1) rotates in the forward direction, a point depressed from the point of the tom through a curved portion, and a straight line portion from the depressed point. It is a direction that crosses in the order of a sharp point via.

The point of the heart of the groove (15) of the housing, that is, the point farthest from the axis, the distance from the axis is determined by the two pointed points of the tomogram of the groove (9) of the rotor, That is, the distance from the shaft center of the groove (15) of the housing is equal to the distance from the shaft center of the point furthest from the shaft center, and the distance from the shaft center of the most concave point of the heart of the housing is (15). It should be equal to the distance from the axis of the concave point. The sharp point of the heart of the groove (15) of the housing is approximately in the direction between the intake port (18) and the exhaust port (19) when viewed from the shaft hole (13). When viewed from 7), they are arranged in the directions of the rotor heads (3) and (5), respectively.

A hole (21) is formed in the output shaft (20) to penetrate in the radial direction, and a rod (23) having a cross section substantially equal to the cross section of the hole is inserted through the hole. The rod is slidable in the radial direction of the output shaft. A space is provided between the inner surface of the housing and the side surface of the rotor so that the rod (23) does not hit each side surface when the rod (23) slides and rotates together with the output shaft. At one end of the rod (23), a rod-shaped projection (25) having a circular cross section substantially protruding from the width of the rod in the output axis direction and having an outer diameter substantially equal to the width of a groove formed in the housing and the rotor is provided. Both ends of the projection are simultaneously fitted into the grooves (15) and (9) formed in the housing and the rotor. Both ends of the rod-shaped projection are slidable along respective grooves.

The inner surface of the right piece (12) of the housing is also provided with a heart-shaped groove (16) that goes around the shaft hole (14) in the same manner as the inner surface of the left piece. And the rotor (2) facing the groove is provided with a toroidal groove (10). As with the rotor (1), the direction of the tomogram is as follows: an imaginary line extending in the radial direction from the output shaft when the rotor rotates forward, a point depressed through a curved portion from a point at the point of the tom, It is a direction that crosses in the order of from the point to a sharp point via a straight line part.

In the output shaft (20), the hole (2
Another hole (22) is opened at a distance substantially equal to the thickness of the rotor (1) (2) from 1) and penetrates the shaft in the same direction as the hole (21). A rod (24) having a rod-shaped projection (26) formed at one end thereof is inserted into the hole (22) such that the rod-shaped projection is on the same side as the rod-shaped projection (25) provided on the rod (23). 26) are simultaneously fitted into the grooves (16) and (10) formed in the housing and the rotor. Both ends of the rod-shaped projection are slidable along respective grooves. At the stage when the rod-shaped projections provided on the two rods are fitted into the grooves engraved on the housing and the rotor,
The three rotors and the output shaft are not rotatable with respect to each other. A friction reducing member such as a sintered oil-impregnated metal, a roller, a bearing, or the like is mounted between the edge of the groove formed in the housing and the rotor and the rod-shaped projection or between the hole formed in the output shaft and the rod.

The groove formed in the inner surface of the housing is not limited to a symmetrical heart shape but may be an asymmetrical shape, as long as it can restrict the movement of the rod-shaped projection in the radial direction of the output shaft. The shape may be a perfect circle or an ellipse shifted so as not to be concentric. Since the grooves formed in the rotor need only be able to change the component of the force acting on the rod-shaped projections in the rotational direction, the straight part can be made a gentle curve instead of a perfect straight line, and it can also be sharp and pointed. Points can also be rounded so that the rod-like projections can slide easily. The cross-sectional shape of both ends of the rod-shaped projection is not circular, but may be semicircular or another shape so as to easily receive a force in the rotational direction from the groove of the rotor. Needless to say, their shapes and orientations can be varied in order to facilitate smooth movement and efficient transmission of force.

When an even number of four or more rotor heads is provided on each rotor, the groove formed on the inner surface of the housing has a substantially football shape having two sharp points, or a substantially triangular shape having three sharp points. To have multiple sharp points. At this time, the groove on the side surface of the rotor may be a tomogram having two sharp points, but may be a windmill having an even number of sharp points such as four or six. It goes without saying that the ignition device or the fuel injection device, the intake port, and the exhaust port are each increased.

The distance of the groove engraved in the housing from the axis farthest or closest to the output axis is the distance from the axis farthest or closest to the axis of the groove of the rotor. It is not always necessary to make them equal to each other. For example, the positions of both ends of the rod-shaped projection provided on the rod may be shifted in the radial direction of the output shaft. Throughout this specification, the shape of the groove refers to the center line of the groove, and it is obvious that the lines at both edges of the groove are different between the inside and the outside.

[0016] Even if the directions of the hearts of the grooves engraved in the left piece and the right piece of the housing are not reversed, and the two holes formed in the output shaft are not in the same direction, ie, the rods (23) and (24) are It works even if they are in any directions, but here the directions of the hearts in both grooves are reversed, and the two holes are in the same direction. Then, when the two rods slide while rotating together with the output shaft, the direction of movement of the center of gravity is reversed, and the generation of vibration is suppressed.

In the above description, the rod is inserted into the hole formed in the output shaft. On the contrary, the rod is enlarged so that the parallel surface is partially sandwiched between the parallel surface and the diameter of the output shaft. The rod may be provided with a hole or notch having a length that can slide in the direction, and the output shaft may be clamped by the rod.

The rod may be slidably held in the radial direction of the output shaft, or may be held so as to be able to swing along a plane perpendicular to the output shaft. That is, a part of the output shaft is cut off, or two projections are arranged on the output shaft in the axial direction, and the rod is pivotally held between the walls facing the axial direction by a rod holding pin, or the output is A configuration in which a crank is provided on a shaft and the rod is swingably held on the crank portion, or the rod is swung along a plane perpendicular to the output shaft by other methods. A rod-like projection is provided at the other end of the two rods which are swingably held in this form, and both ends of the rod-like projection are simultaneously fitted into grooves formed in the housing and the rotor. When the rod is swingably held on the output shaft, the rod may not necessarily be an integral rigid rod but may be partially connected with a pin or the like,
A flexible substance may be used as the material, and the material may be partially swung by bending.

The cat-and-mouth type rotary engine of the present invention does not require an intake valve or an exhaust valve, but facilitates adjustment of intake compression, or timing of fuel injection or ignition explosion, or a mechanism capable of internal cooling. For this purpose, an intake valve and an exhaust valve may be provided. Others
The cat and mouse type rotary engine of the present invention is not limited to the shapes and combinations shown in the embodiments to be described later, and many other variations can be considered.

[0020]

Suppose that the rotor heads (3) and (4) are located at positions sandwiching the ignition device or the fuel injection device (17), and an explosion cycle is about to begin between the two rotor heads. At this time, the rotor heads (5) and (6) are located at positions sandwiching the end of the intake port (18), and an intake cycle is about to start between the two rotor heads.
Each rotor and output shaft are from the rotor (1) side to the rotor (2).
And rotate clockwise. At this time, the bar-like projection (26) comes to a point slightly down to the linear portion from the point where the toe of the groove (10) of the rotor (2) is sharp, and at the same time, the bar-like projection (26) At a point slightly below the point where the heart is sharp.

When an explosion occurs here, the explosive force received by the rotor head (4) is applied to the toroidal groove (10) of the rotor (2).
Through the edge of the groove to the rod-like projection (26) fitted in the groove. Since the rod-shaped projection is located in the linear portion of the groove, and the direction of the straight line is approximately in the radial direction of the output shaft, the component in the rotation direction of the force received by the rod-shaped projection from the edge of the groove is large, and The component force is small. In other words, a large force is exerted on the rod-like projection (26) to move it in the rotation direction. At the same time, the bar-shaped projection is in the heart-shaped groove (16) of the housing,
Since the direction of the groove is substantially in the direction of rotation, the rod-shaped projection (26) does not receive a large force that hinders the movement in the direction of rotation from the heart-shaped groove (16). After all, the rod-shaped protrusion (2
6) starts to move in the rotation direction.

On the other hand, at this time, the rod-like projection (25) is located at a point slightly advanced from the recessed point of the groove of the groove (9) of the rotor (1), and has a direction opposite to the rotation direction received by the rotor head (3). Is transmitted from the curved portion of the groove, but since this curve is substantially oriented in the rotational direction, the radial component of the force received from the edge of the groove is large and the component in the reverse rotation direction is small. In other words, the force for moving the bar-shaped projection (25) in the reverse rotation direction is small.

Therefore, the output shaft is rotated in the rotation direction via the rod (24) by the rod-shaped projection (26) which starts to move by receiving a large force in the rotation direction. Rod-shaped protrusions (2
6) is guided by the groove (16) of the housing while rotating around the output shaft in the rotational direction, and heads toward the concave point of the heart of the groove, and at the same time, toward the concave point of the tom in the groove (10) of the rotor. When the rod-shaped projection reaches a point slightly advanced from the concave point of both grooves, the rotor head (4) reaches the position where the original rotor head (5) was.

On the other hand, the rod-shaped projection (25) is pushed in the rotational direction via the rod (23) according to the rotation of the output shaft, and is guided by the groove (15) of the housing toward the sharp point of the heart of the groove. At this time, the rotor (1) moves since the direction of the tom-shaped groove (9) is slightly oblique to the direction of the heart-shaped groove (15) of the housing at the position of the rod-shaped projection (25). The edge of the trough-shaped groove (9) is pushed by the rod-shaped projection (25) and gradually rotates in the rotation direction of the output shaft. The rotor head (3) reaches the position where the original rotor head (4) was located when the rod-like projection (25) reaches a point slightly lower than the point where both grooves are sharp. Thus, the explosion stroke between the rotor head (3) and the rotor head (4) ends, and the intake stroke between the rotor head (5) and the rotor head (6) also ends.

At this time, the exhaust stroke has been completed between the rotor heads (4) and (5), and the compression stroke has been completed between the rotor heads (6) and (3). Each step of intake and explosion begins between the rotor heads. By repeating the above, the cat and mouse type rotary engine according to the present invention moves. Note that the position of the rod-shaped projections (25) and (26) in the rotation direction at the start of the explosion may deviate from the position described above depending on the rotation speed of the engine and the timing of ignition or fuel injection.

In the above description, one cycle of each of the intake compression explosion and exhaust was performed. However, this cycle is performed by providing an even number of rotor heads, such as four or six, for each rotor in one housing, the intake port exhaust port and By providing a plurality of ignition devices or fuel injection devices, a plurality of intake compression, explosion, and exhaust cycles can be performed simultaneously in parallel. In this case, the groove on the inner surface of the housing may have a shape having a plurality of sharp points, such as a substantially football shape having two sharp points, or a substantially triangular shape having three sharp points. The groove on the side of the rotor can be a Tomoe with two pointed points,
This may be a windmill shape having an even number of sharp points, such as 4 or 6. The rod operates with two rods.

In addition, one or more of the above plurality of intake compression, explosion and exhaust cycles are left, and the other intake compression, explosion and exhaust cycles are simply made into intake and exhaust cycles, and air and other fluids are taken in from the outside. It is also possible to adopt a configuration in which the inside of the housing and the rotor head are cooled. In this case, an intake port and an exhaust port are newly provided at the position of the ignition device or the fuel injection device at the portion where cooling is performed. Furthermore, with this configuration, a cat and mouth type rotary engine with a fluid compressor is provided if a tank is provided at the end of the exhaust port provided for cooling the inside of the housing and the rotor head, and a blower is provided if a blow port is provided. It can be a cat and mouse type rotary engine.

Further, the above-described cat-and-mouth type rotary engine of the present invention has a configuration in which an ignition device or a fuel injection device is removed from the configuration, a tank or an outlet is provided, and an external power is connected to the output shaft as an input shaft to connect the cat. And-mouth type rotary fluid compressor or blower.

The cat and mouse type rotary engine of the present invention is not limited to the above-described embodiment, and can be made in various configurations.

[0048]

As described above, the cat-and-mouth type rotary engine of the present invention suffers from gear damage and severe wear caused by the conventional cat-and-mouth type rotary engine using two sets of deformed gears. This eliminates the drawbacks that occur, and also eliminates the energy loss associated with power conversion, which was a problem with using a generator to extract power. Moreover,
The conventional cat-and-mouth type rotary engine has two sets of deformed gears provided outside the housing to increase the overall size. However, in the cat-and-mouth type rotary engine of the present invention, an energy conversion mechanism is provided inside the housing. As a result, the merit that the overall size can be reduced was also born.

In summary, (1) the component rotates smoothly without damaging or severely abrading parts. (2) Energy is efficiently converted into rotational force. (3) Each component can be industrially produced, and the entire structure can be mass-produced industrially. (4) The overall size is reduced, and the material size is reduced due to the reduced size. (5) Special processing is not required, thereby reducing processing costs and improving productivity. This has the effect.
