  1 and 2 show an air amplifier 101 according to a first embodiment of the present invention.

  The amplifier 101 includes a passage path 110 that is formed inside and through which the main airflow passes. A first chamber 112, a second chamber 114, and a third chamber 116 serving as a branch chamber are arranged in the passage route 110 along the main air flow. Each compartment 112, 114, 116 is constituted by cylindrical outer walls 112A, 114A, 116A. In the first chamber 112, a passage hole 112B for discharging air to the second chamber 114 side is formed. In the second chamber 114, a passage hole 114B for discharging air to the third chamber 116 side is formed. In the third chamber 116, a passage hole 116B for discharging air to the outside is formed. The first chamber 112, the second chamber 114, and the third chamber 116 are integrally molded as a whole.

  Further, the inner diameter d2 of the second chamber 114 is larger than the inner diameter d1 of the first chamber 112. Furthermore, the inner diameter d3 of the third chamber 116 is larger than the inner diameter d2 of the second chamber 114. Thus, amplification efficiency is increased by increasing the inner diameter of the compartment toward the downstream side. In addition, air suction from the outside is realized in a rational shape by arranging an air suction port described later by using this step.

  Further, the inner diameter of the passage hole 114B in the second chamber 114 is set larger than the inner diameter d4 of the passage hole 112B in the first chamber 112, and the third inner diameter is larger than the inner diameter of the passage hole 114B in the second chamber 114. The inner diameter of the passage hole 116B in the chamber 116 (this coincides with the inner diameter d3 of the third chamber 116) is set large.

  On the discharge side in the first chamber 112, a tapered throttle portion 112C having a path diameter that decreases in the discharge direction is provided. Therefore, the passage hole 112B is disposed at the protruding end of the throttle portion 112C. Similarly, on the discharge side in the second chamber 114, a tapered throttle portion 114C having a path diameter that decreases in the discharge direction is provided. Therefore, the passage hole 114B is disposed at the protruding end of the throttle portion 114C. By these throttle parts 112C and 114C, the flow velocity of air is increased and the generation efficiency of internal negative pressure is increased. The third chamber 116 is not formed with a throttle portion. This is because it is not necessary to generate a negative pressure on the downstream side.

  A plurality of air suction ports are arranged on the outer periphery of the passage route 110. Specifically, in the vicinity of the boundary with the first chamber 112 on the outer periphery of the second chamber 114, four air suction ports 114D for the second chamber are arranged at intervals of 90 degrees in the circumferential direction. In addition, four third chamber air suction ports 116D are arranged at intervals of 90 degrees in the circumferential direction near the boundary with the second chamber 114 on the outer periphery of the third chamber 116. When the main air flow passes through the passage path 110, the pressure in the second chamber 114 becomes negative, air is sucked from the second chamber air suction port 114D, and merges with the passage path 110. Similarly, when the main airflow passes through the passage path 110, the pressure in the third chamber 116 becomes negative, air is sucked from the third chamber air suction port 116D, and merges with the passage path 110.

  The air suction port 114D for the second chamber is disposed along the outer wall of the throttle portion 112C in the first chamber 112 using its tapered shape. At this time, the air suction port 114D for the second chamber joins at an acute angle α with respect to the flow direction of the main air flow in the passage path 110. Similarly, the third chamber air suction port 116 </ b> D is disposed along the outer wall of the throttle portion 114 </ b> C in the second chamber 114 using its tapered shape. At this time, the air suction port 116D for the third chamber merges with an acute angle α with respect to the flow direction of the main air flow in the passage path 110. Thus, by joining at an acute angle α, the resistance at the time of joining is reduced, and the amplification efficiency is increased.

  Next, an air amplifier 201 according to the second embodiment will be described with reference to FIG. In the second embodiment, the difference from the air amplifier 101 of the first embodiment will be mainly described. For the same or similar parts, the last two digits of the reference numerals are matched with those of the first embodiment. Description and illustration are omitted.

  The air amplifier 201 includes a fourth chamber 218 in addition to the first chamber 212, the second chamber 214, and the third chamber 216. Therefore, although not particularly illustrated, the third chamber 216 is also formed with a narrowed portion having a tapered diameter, and air is discharged to the fourth chamber 218 from the passage hole at the tip. A fourth chamber air suction port 218D is formed on the outer periphery of the fourth chamber 218, and sucks air to further amplify it. Thus, the amount of amplification can be increased by increasing the number of compartments on the passage route 210.

  Next, an air amplifier 301 according to a third embodiment will be described with reference to FIG. In the third embodiment, the difference from the air amplifier 101 of the first embodiment will be mainly described, and for the same or similar parts, the last two digits of the reference numerals are matched with those of the first embodiment. Description and illustration are omitted.

  In the air amplifier 301, the first chamber 312, the second chamber 314, and the third chamber 316 are separable. Specifically, a cylindrical engagement portion 314E is formed on the upstream side of the second chamber 314, and the first chamber 312 is inserted into the engagement portion 314E so that they can be detachably fitted to each other. It is like that. A cylindrical engaging portion 316E is also formed on the upstream side of the third chamber 316, and the second chamber 314 is inserted into the engaging portion 316E so that they can be detachably fitted to each other. As described above, the steps formed between the first chamber 312 and the third chamber 316 are effectively utilized, and are fitted in a nested manner to facilitate disassembly and assembly. As a result, maintenance is also simplified.

  In the air amplifier 301, a plurality of auxiliary holes 312 </ b> F are further provided around the passage hole 312 </ b> B of the first chamber 312. The auxiliary hole 312F can also pass air, and the main air flow is discharged to the second chamber 314 side through both the passage hole 312B and the auxiliary hole 312F. As a result, the air amplification efficiency can be increased.

  Next, an air amplifier 401 according to a fourth embodiment will be described with reference to FIG. In the fourth embodiment, the difference from the air amplifier 101 of the first embodiment will be mainly described. For the same or similar parts, the last two digits of the reference numerals are matched with those in the first embodiment. Description and illustration are omitted.

  The air amplifier 401 has an integral structure in which the passage route 410 is not divided into compartments. A throttle portion 410A is disposed in the vicinity of the entrance of the passage route 410, and the flowed air is once throttled to increase the flow velocity. In addition, the downstream side of the narrowed portion 410A in the passage route 410 has a tapered shape that gradually increases from the air entry side toward the air discharge side. Therefore, the diameter d7 on the outlet side is larger than the diameter d6 on the inlet side. In addition, a first air suction port 410B and a second air suction port 410C are arranged on the outer periphery of the tapered passage route 410 with a certain interval in the axial direction. Note that the structure and function of the air suction ports 410B and 410C are the same as those of the air suction port of the first embodiment, and a description thereof will be omitted. Thus, by smoothly increasing the inner diameter of the passage route 410, the air flow resistance is reduced, and the amplification efficiency can be increased.

  In addition, as shown in FIG. 6, it is desirable to form a plurality of grooves 410D on the inner peripheral wall of the tapered passage passage 410. The spiral groove 410D generates a swirl in the main air flow and improves amplification efficiency.

  Although not particularly shown in the first to fourth embodiments, a check valve (check valve) is installed in each air intake port. By doing in this way, the flow of the air which goes to a passage route from an air suction port is permitted, and the driving force of amplification can be improved further by suppressing the opposite flow.

  FIG. 7 shows a fifth embodiment of the present invention, which is an air circulation circuit having a component configuration of 1 to 22. Here, the operation of the air circulation circuit will be described at the same time as the description of each component configuration, but the description of the air amplifier will be omitted because the air amplifier of the first to fourth embodiments may be used as appropriate. 12 and 13 are flowcharts showing the operating state of the air circulation circuit.

  When using the air motor 12 as power, as a preparation before starting, the compressor 1 is started to obtain compressed air to be used for starting first, and the starting air tank 3 is compressed by 9 kpa using the air charge valve 2. Initial filling with air. Next, the air stop valve 6 is opened, and the compressed air is brought to the three-way valve.

  Next, the solenoid valve 11 of the accelerator is turned ON so that compressed air flows from the three-way valve 8. The compressed air is automatically controlled to 7.0 kpa by the air control unit 9 and passes through the first air amplifier 10-1. In the first air amplifier 10-1, the air flow rate increases about 10 times. The increase is shown in Table 1 in terms of the amount of air at the air amplifier inlet and the amount of air increase at the outlet. The circulating air that has accumulated energy by increasing the air drives the air motor 12 through the accelerator 11. As a result, the air motor 12 rotates to generate power.

  The exhaust circulation air discharged from the air motor 12 is separated into two directions of A flow and B flow by the first flow divider 13. The exhaust circulating air in the A-flow direction is stored in the first surging tank 14, and further passes through the second air amplifier 10-2 and the third air amplifier 10-3 to reach the third surging tank 18. On the other hand, the exhaust circulation air in the B flow direction reaches the air regulator 15. Through this air regulator 15, the exhaust circulation air is discharged to the intake port of the blower 16 that is belt-driven by the air motor 12. At this time, excess exhaust air is discarded.

  The air sent by the blower 16 is stored in the second surging tank 17 and is connected to the outer periphery of the second air amplifier 10-2 and the third air amplifier 10-3 by pipes through the intake holes with check valves. Supplied inside. The structures of the second air amplifier 10-2 and the third air amplifier 10-3 are substantially the same as those of the first air amplifier 10-1 already described, except that a check valve is installed at each intake port. Since it is a structure, description thereof will be omitted.

  As already described, the exhaust circulating air in the A-flow direction passes through the inside of the second air amplifier 10-2 and the third air amplifier 10-3, whereby the second air amplifier 10-2 and the third air amplifier Since the inside of 10-3 becomes negative pressure, the exhaust circulating air of this B flow is also sucked and merged into the second air amplifier 10-2 and the third air amplifier 10-3, and the second air amplifier 10 -2 and the exhaust air circulation amount of the third air amplifier 10-3 increase. The increased exhaust circulation air is stored in the third surging tank 18.

  The exhaust air circulating through the third surging tank 18 is supplied to one of the second flow dividers 19 divided in two directions. Further, the compressed air of the second compressor 21 is supplied to the other of the second flow divider 19 divided in two directions. Therefore, in the second flow divider 19, the two airs merge and are stored in the fourth surging tank 20. The air stored in the fourth surging tank 20 returns to the other connecting portion of the three-way valve 8, flows into the first air amplifier 10-1, and flows to the air motor 12 to generate power. Until the solenoid valve 22 of the accelerator 11 is turned off, the air circulation process is repeated and the generation of power continues.

  In addition, a third compressor 22 for maintaining pressure is connected to the starting air tank 3 in order to keep its internal pressure at 9 kpa. Thereby, the pressure is always maintained in the starting air tank 3.

  Here, the case where the check valve 7 is disposed in the air supply path before the three-way valve 8 is shown, but for example, as shown in FIG. 8, the three-way valve 8 itself is used for starting. This check valve 7 can be obtained by using the one having a function of sending the compressed air sent from the air tank and the air sent from the fourth surge tank 20 in the direction of the air control unit 9 in preference to the one having a higher pressure. It is unnecessary. Further, as shown in FIG. 9, it is preferable to arrange a T-shaped pipe in place of the three-way valve and provide a check valve 7 in each of the air supply paths. In this way, the air circulation circuit is effectively performed by sending a higher pressure preferentially in the next direction.

  In FIG. 10, the air regulator 15 and the blower 16 are shown enlarged. Exhaust air from the air motor 12 is sent to the suction port of the blower 16 via the air regulator 15. At this time, excess exhaust air is not taken into the suction port and is discharged to the outside. This increases the efficiency of the circulating exhaust air and at the same time stabilizes the circulation circuit.

FIG. 11 shows the third compressor 22 in an enlarged manner. The third compressor 22 is provided with a clutch on its drive shaft, and the power generated by the air motor 12 is introduced into the third compressor 22 via this clutch. Thus, the driving power of the third compressor 22 effectively uses the power generated by the air motor 12.

  14 and 15 show an air circulation circuit according to a sixth embodiment of the present invention. In the circulation circuit, only the parts different from the fifth embodiment will be described, and the same or similar parts will not be described by matching the reference numerals in the description and illustration.

  In this circulation circuit, instead of the first air amplifier 10-1, a fourth air amplifier 10-1 that is the same as this is arranged between the third surge tank 18 and the shunt 2. Therefore, at the time of starting, first, the compressed air is accumulated in the starting air tank 9, and the solenoid valve 11 of the accelerator is turned ON. As a result, the air automatically controlled to 7.0 kpa by the air control unit 9 through the three-way valve 8 is directly supplied to the air motor 12. The circulating compressed air that has passed through the air motor 12 is accumulated in the third surging tank 18 via the second air amplifier 10-2 and the third air amplifier 10-3.

  In the process in which the air stored in the third surging tank 18 returns to the three-way valve 8, the fourth air amplifier 10-1 amplifies the air. Therefore, when the circulation is started, the air flowing through the air motor 12 is amplified by the second to fourth air amplifiers 10-2, 10-3, and 10-4, and the solenoid valve 22 of the accelerator 11 is turned off. Until then, the air circulation process is repeated, and the generation of power continues.

  The air motor rotation power can be easily obtained by effectively arranging the air amplifier on the air circulation circuit. For this reason, it can be used in the automobile industry / ship business-related or general industries. It is especially pollution free and can be used in a wide range of industries.
