As described above, the term "compressor" means a compressor and an expander, and the compressor of the present invention may implement the functions of the compressor and the expander with one fluid machine.

1 is a view schematically illustrating a basic configuration of a compander having a triple trocoidal rotor according to an embodiment of the present invention.

Referring to the drawings, the compander 10 having a triple trocoidal rotor according to the present embodiment, a trocoidal rotor is composed of the three trocoidal rotors (15, 17, 19) are meshed with each other Assembly 13 and a casing 11 for hermetically receiving the assembly 13 therein. The casing 11 may be manufactured in a cylindrical shape having a predetermined diameter.

The trocoidal rotor assembly 13 includes a first rotor 15, a second rotor 17 for receiving the first rotor 15 in an eccentric position thereof, and the second rotor 17. It comprises a third rotor (19) for receiving the in its eccentric position. The first rotor 15 and the second rotor 17 are in line contact with each other on the same principle as in the conventional trocoidal gear pump, and the third rotor 19 is also wired with respect to the second rotor 17. Contact.

The shaft 14 is penetrated and fixed to the central axis of rotation of the first rotor 15. The shaft 14 passes through the first rotor 15 completely and extends in the longitudinal direction, and both ends thereof protrude a predetermined length out of the casing (11 in FIG. 2) as shown in FIG. 2.

The shaft 14 receives the power from an external power source and rotates the first, second, and third rotors 15, 17, and 19 by axially rotating in the direction of arrow a. At the same time, the working fluid is sucked to the first and second discharge ports 25 and 27, and the compressed working fluid is expanded and discharged, or high pressure and high speed is applied to the first and second suction ports 21 and 23. When the working fluid is press-fitted and the first, second and third rotors 15, 17, and 19 are rotated by the expansion force of the working fluid, they rotate in the direction of arrow a and provide a rotational torque to the outside.

That is, the shaft 14 is a shaft that receives a rotational torque from the outside or provides a rotational force to the outside.

Both ends of the drive shaft 14 pass through the casing 11 and the outer circumferential surface thereof is supported by the casing so that the rotation center of the first rotor 15 is always kept constant.

On the outer circumferential surface of the first rotor 15, a known trocoidal gear tooth is formed. In the present embodiment, six gear teeth are formed, and the tooth root between each gear teeth has a curved shape.

In addition, the second rotor 17 takes the form of a hollow cylinder, and a trocoidal gear is formed on the inner and outer circumferential surfaces thereof. The gear teeth formed on the inner circumferential surface of the second rotor 17 are engaged with the gear teeth formed on the first rotor 15, and the number thereof is seven more than that of the first rotor. The first rotor 15 and the second rotor 17 have a meshing structure and an operating mechanism such as a known trocoidal gear.

The gear teeth formed on the outer circumferential surface of the second rotor 17 correspond to the gear teeth formed on the inner circumferential surface and have the same number and take the form of a conventional trocoidal gear.

The third rotor 19 is a rotor capable of relative movement with respect to the casing 11, the gear is formed on the inner peripheral surface. The gear teeth formed in the third rotor 19 maintain the engagement state of the gear teeth formed on the outside of the second rotor and the conventional trocoidal gear system. In addition, the number of gear teeth formed in the third rotor 19 is eight, one more than the second rotor 17.

Meanwhile, in the casing 11, first and second suction ports 21 and 23 are provided at one side of the shaft 14, and first and second discharge ports 25 and 27 are provided at the other side.

Each port is a connecting passage connecting the inside and the outside of the casing 11, and the first and second suction ports 21 and 23 are passages for guiding the external working fluid into the casing 11, respectively. The discharge ports 25 and 27 are passages for discharging the working fluid compressed in the casing 11 to the outside of the casing 11.

The first and second suction ports 21 and 23 may be disposed between the first rotor 15, the second rotor 17, and the third rotor 19 with respect to each other when the shaft 14 rotates in the direction of the arrow a. It is located where it starts to open and its internal pressure drops. Thus, for example, when the shaft 14 rotates in the direction of arrow a, the working fluid flows between the first rotor 15 and the second rotor 17 through the second suction port 23 and the first suction port 21. It can be introduced between the second rotor 17 and the third rotor 19 through.

In addition, the second discharge port 27 is located at a portion where the internal pressure increases by narrowing between the first rotor 15 and the second rotor 17, and the first expansion discharge port 25 is the second rotor. The volume between the 17 and the third rotor 19 is located at the moment when the volume starts to shrink after the maximum expansion. When the rotor rotates at a high speed, the first expansion discharge port 25 may be positioned more upstream.

The working fluid introduced into the first and second suction ports 21 and 23 is compressed according to the continuous rotation of the shaft 14, and the working fluid between the first rotor 15 and the second rotor 17 is discharged secondly. It is discharged through the port 27, the working fluid between the second rotor 17 and the third rotor 19 is expanded and discharged through the first discharge port (25).

The position and the flow cross-sectional area of the suction port and the discharge port depend on the shape and size of each gear, and in particular, when adjusting the position and the flow cross-sectional area, the output of the compander can be adjusted.

FIG. 2 is a side view of the compander shown in FIG. 1.

Referring to the figure, the shaft 14 penetrates through the casing 11 and protrudes from both sides of the casing 11. Since the shaft 14 extends outside of the casing 11, a drive source such as a motor or an engine may be connected to the shaft 14, or a load required by an axle or other power may be connected.

In addition, it can be seen that the first and second suction ports 21 and 23 and the first and second discharge ports 25 and 27 are located at both sides of the shaft 14. The suction ports 21 and 23 and the discharge ports 25 and 27 may be connected to separate pipes.

3A and 3B are diagrams for explaining two operation mechanisms of the compander.

The first operating mechanism is to draw the working fluid into two suction ports at the same time and discharge them simultaneously to the two discharge ports.

The second operating mechanism is to first inject the working fluid into the first suction port 21 and to compress the first, and then pass through the first discharge port 25 and the second suction port 23 in order in the casing 11. After the second compression is discharged to the final second discharge port (27).

3A is a diagram for explaining the first operation mechanism described above.

Referring to the drawings, it can be seen that the working fluid is sucked into the first and second suction ports 21 and 23 at the same time along the arrow p direction. As such, the working fluid sucked at the same time through the first and second suction ports 21 and 23 is compressed through the inside of the casing 11 and then discharged through the first and second discharge ports 25 and 27 in the direction of the arrow q. (Exhaust ports 25 and 27 are expanded and compressed according to their position).

3B is a diagram for explaining the second operation mechanism described above.

As shown, the first discharge port 25 and the second suction port 23 are connected through a connection pipe 29. Therefore, the working fluid supplied into the casing 11 through the first suction port 21 along the arrow p direction is first expanded in the casing 11 and then the arrow q direction through the first expansion discharge port 25. After passing through the cooler along the connecting pipe 29 and moves to the second suction port (23). The working fluid moved to the second suction port 23 is compressed into the casing 11 again and then compressed and discharged to the outside through the second discharge port 27.

Thus, expansion and compression occur continuously at the same time.

4A, 4B, and 4C are views sequentially shown to explain the operation of the trocodal rotor assembly in the operation mode shown in FIG. 3A.

As described above, when the shaft 14 rotates, the assembly 13 rotates as a whole, during which the first rotor 15 and the second rotor (where the first and second suction ports 21 and 23 are located). The space between 17 and the space between the second rotor 17 and the third rotor 19 are opened.

Accordingly, the pressure between the first, second, and third rotors 15, 17, and 19 is lowered so that an external working fluid passes through the first and second suction ports 21 and 23, as shown in FIG. 4A. Flows inside.

If the shaft 14 continues to rotate in the above state, the working fluid rotates in a state trapped between the first, second, and third rotors 15, 17, and 19, as shown in FIG. 25, 27) gradually closer to the side.

Subsequently, as shown in FIG. 4C, when the working fluid moving in the locked state between the rotors 15, 17, and 19 finally reaches the first and second discharge ports 25 and 27, the working fluid is discharged from both discharge ports 25,. 27) at the same time inflated and discharged (25 is expanded and 27 is compressed).

5A to 5F are views sequentially shown to explain the operation of the trocoidal rotor assembly in the operation mode shown in FIG. 3B.

As shown in FIG. 5A, when the driving shaft 14 is rotated, an external working fluid moves into the casing 11 through the first suction port 21. The working fluid moved into the casing 11 through the first suction port 21 moves toward the first expansion discharge port 25 in a state of being trapped between the second rotor 17 and the third rotor 19. And expand (see FIG. 5B).

Subsequently, as shown in FIG. 5C, the working fluid reaching the first expansion discharge port 25 is expanded through the first expansion discharge port 25 to the outside of the casing 11, and exits the connection pipe (FIG. 3B). After passing through the cooler through 29), the temperature of the air is lowered and then moved to the second suction port 23.

As described above, the working fluid moved to the second suction port 23 is sucked between the first rotor 15 and the second rotor 17 as shown in FIG. It moves to the second discharge port 27 in a compressed state between the first rotor 15 and the second rotor 17 to be discharged to the cooler and then discharged to the compression tank (see FIG. 5F).

As described above, the compander according to the embodiment of the present invention expands or compresses the speed of the shaft due to expansion of a working fluid, expands and compresses therein, and mixes compressed air with gas in a direct combustion chamber to increase the combustion expansion pressure to 21. After entering, it expands to 25 and exhausts it to the outside. It rotates shaft 14, and 23 receives compressed air and compresses and discharges it to 27. After that, the open cycle and compressed air are supplied to the combustion chamber through the pressure tank. It can be applied to various torque generators because it has two characteristics as a closed cycle that does not mix with.

6 is a configuration diagram showing an example of a torque generating device using the compander. Of course, the shaft in which the above-mentioned torque is generated is the shaft 14 of the compander.

As shown, the second discharge port 27 of the compander 10 is connected to the compressed air tank 51. The compressed air tank 51 is a general high pressure air tank to temporarily store the compressed air discharged from the second discharge port 27 of the compander.

In addition, the compressed air tank 51 is connected to the combustor 53 through a plurality of valves. The combustor 53 is a place where combustion takes place inside, like a combustion chamber of a reciprocating engine cylinder. The combustor 53 has a combustor chamber 55 for receiving the compressed air that has moved from the compressed air tank 51 and the external gas supplied by the pressure pump 59, and inside the combustor chamber 55. And an spark plug 57 that sparks and ignites, and relates to an open cycle.

The high speed and high pressure combustion gas generated in the combustor 53 is moved into the compander 10 through the first suction port 21 of the compander 10. As such, the combustion gas moving into the compander 10 moves to the first expansion discharge port 25 between the second rotor 17 and the third rotor 19 as shown in FIG. 5A. The two rotors 17 and the first rotors 15 are rotated in the counterclockwise direction of FIG. 5A and are expanded and exhausted through the first discharge port 25. As described above, when the first rotor 15 rotates, the shaft 14 also rotates, so that torque can be transmitted to the outside through the shaft 14.

Meanwhile, as described above, the combustion gas passes through the compander 10 and the first and second rotors 15 and 17 are rotated so that new air from outside flows through the second suction port 23 to the casing 11. ) Compressed inside. The air sucked into the second suction port 23 moves to the compressed air tank 51 through the second discharge port 27 in a compressed state between the first and second rotors 15 and 17 and the combustion chamber ( Wait to go to 53).

7 is a configuration diagram showing another example of the torque generating apparatus using the above-described compander.

The same reference numerals as the above reference numerals denote the same members having the same function, and repeated description thereof will be omitted.

The compander 10 in the torque generating device explained with reference to FIG. 7 has the operation mechanism of FIG.

Referring to the drawings, it can be seen that the first expansion discharge port 25 and the second suction port 23 of the compander 10 is connected to the cooler 71, and relates to a closed cycle. The cooler 71 is a known general cooler and cools the gas discharged to the first expansion discharge port 25 to supply it to the second suction port 23.

In addition, the second discharge port 27 is connected to the compressed air tank 51 and the compressed air tank 51 is connected to the combustor 53. The compressed air in the compressed air tank (51) is heated while passing through the combustor and moves to the first suction port (21) to rotate the first and second rotors (15, 17) and torque to the outside through the shaft (14). Occurs. The combustion gas rotated by the first and second rotors 15 and 17 is not discharged to the atmosphere but moves to the cooler 71 through the first expansion discharge port 25.

The combustor 53 heats a pipe through which compressed air moves by igniting with the outside air and gas accommodated therein.

In any case, the inflated air moved to the cooler 71 passes through the cooler 71 and then flows into the case 11 once again through the second suction port 23 as shown in FIG. It is compressed between the 15 and the second rotor 17 and moves to the compressed air tank 51 through the second discharge port 27 as shown in FIG. 5F to wait.

8 is a configuration diagram showing still another example of the torque generating device using the compander. Basically, the torque generating device shown in Fig. 8 is a device for generating torque on the shaft of one of the accelerators using a compressor and an accelerator.

Referring to FIG. 8, the torque generator includes a compressor and an accelerator (10a, 10b), a combustor 53 and a heat exchanger (81) positioned between the two (10a, 10b). The compressor and the expander (10a, 10b) has the same configuration, one side (10a) serves as a compressor (compressor) and the other side (10b) serves as an expander (expander).

 The first discharge port 25 of one side 10a, which acts as a compressor, is connected to the second suction port 23 of the other accelerator 10b through the supply line 82. In addition, the supply line 82 is provided with a combustor (53).

The combustor 53 burns by adding gas to the compressed air supplied from the compressor 10a through the supply line 82, and the explosive force according to the combustion is passed through the second suction port 23 to the other accelerator 10b. To be delivered to. When the combustion gas is pressurized through the second suction port 23 to the other side of the accelerator 10b, the first, second and third rotors 15, 17, and 19 are pushed and rotated by the explosive force of the gas, and the shaft 14 is rotated. Rotate

Combustion gas discharged to the second discharge port 27 by returning the inside of the accelerator 10b moves along a predetermined path through the recovery line 83 and in the meantime is directed toward the combustor 53 through the supply line 82. Heat exchanged with cold compressed air and exhausted to atmosphere. The compressed air directed to the combustor is preheated through heat exchange with the hot combustion gas in the recovery line 83.

Meanwhile, while the operation continues, compressed air is continuously sucked into the first suction port 21 of the other accelerator 10b, and the sucked air is first expanded in the expanded state inside the accelerator 10b. Discharged through 27. The expanded air discharged through the first discharge port 25 is discarded after heat exchange. Here, the compressed air in the compressor may be stored in the compressed air tank 51, of course.

Reference numeral 85 is a belt connecting the two compressors and the shaft 14 of the accelerator.

As a result, the torque generating device shown in Fig. 8 has a mechanism for burning the compressed air supplied by the compressor 10a on one side and axially rotating the shaft 14 of the other accelerator with the explosive force.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention. .

The suction volume and discharge of working fluid can be increased to provide high speed high pressure compression performance. In addition, the mutual heat exchange and mechanical efficiency are increased, and the torque generator using the same does not need to separately heat the compressed air (combustion gas, heat-expanded air and compressed heat), and position the suction and discharge ports. By adjusting, control of compression ratio and expansion ratio is possible, the structure is solid, no noise and vibration, and high speed rotation is possible. In addition, by attaching several companders on one axis, there is no effect of stopping or abnormality of the device even in the event of high power and equipment failure.
