In the present invention, an external circuit of the power air motor is prevented from being reduced by incorporating an electric circuit mainly including a storage battery and an alternator into the air circulation circuit. Specifically, in order to maintain the output of the motive power air motor in a stable state at all times, the electric charging compressor is operated using an electric motor powered by a storage battery. As a result, even if the load of the power air motor is large, the pressure drop of the air tank can be suppressed.

In particular, in the present invention, two air circulation circuits are provided, one being a power air circulation circuit and the other being an auxiliary air circulation circuit. As a result, the auxiliary air circulation circuit is used to operate auxiliary equipment other than the output power (for example, a continuous air generating circuit).

In this embodiment of the present invention, two air circulation circuits are provided, one being a power air circulation circuit and the other being an auxiliary air circulation circuit. In addition, as a continuous air generating circuit, an electric circuit centered on a storage battery, an alternator, a compressor, and the like is incorporated to obtain a hybrid to obtain more stable power. In particular, depending on the load of the power air motor, the air tank is replenished with a compressor that uses the output of the auxiliary air motor and an air compressor that is driven by an electric motor that uses the power of the storage battery. By properly using them properly, a stable output is obtained on the power air motor side. This will be described in detail below.

FIG. 1 shows a hybrid air circulation circuit according to an embodiment of the present invention. The hybrid air circulation circuit includes a power air circulation circuit P, an auxiliary air circulation circuit Q, and a continuous air generation circuit R. Here, the operation of the hybrid air circulation circuit will be described at the same time as the description of each component configuration. 2 to 4 are flowcharts showing the operating state of the hybrid air circulation circuit.

First, the continuous air generation circuit R will be described. As preparation before starting, the preparatory compressor 1 is first started to obtain compressed air to be used for starting, and the air tank 3 is initially filled with 0.9 Mpa of compressed air using the air charge valve 2. The air tank 3 is connected to an auxiliary air circulation circuit Q and a power air circulation circuit P via

air stop valves

6 and 106, respectively. Therefore, the

air stop valves

6 and 106 are opened, and the compressed air is made to reach the three-

way valves

8 and 108 of the auxiliary air circulation circuit Q and the power air circulation circuit P, respectively. The air tank 3 is provided with an opening / closing valve 4 and a pressure gauge 5. The pressure gauge 5 functions as a pressure sensor, and can detect the pressure fluctuation of the air supplied to the auxiliary air circulation circuit Q and the power air circulation circuit P.

Next, the auxiliary air circulation circuit Q will be described. Note that the entire route described below corresponds to the auxiliary circulation route in the present invention in which the air discharged from the auxiliary air motor 12 is recirculated to the auxiliary air motor 12. First, in the auxiliary air circulation circuit Q, the solenoid valve of the accelerator 11 is turned ON so that compressed air flows from the three-way valve 8. The compressed air is automatically controlled to 0.63 MPa by the air control unit 9 and passes through the first air amplifier 10-1. As schematically shown in FIG. 5, the first air amplifier 10-1 has a structure in which the inside becomes a negative pressure by the passage of compressed air and the outside air flows in by the negative pressure. Each inflow hole is provided with a check valve 7 to prevent backflow. As a result, in the first air amplifier 10-1, the air flow rate increases about 10 times. The increase is shown in Table 1 in the state of the air amount at the air amplifier inlet and the air increase amount at the outlet. The circulating air that has stored energy by increasing the air drives the auxiliary air motor 12 via the accelerator 11. As a result, the auxiliary air motor 12 rotates to generate power. The auxiliary air motor 12 has a suction port S1 and a delivery port D1, and compressed air is introduced from the suction port S1 and exhausted from the delivery port D1.

The exhaust circulation air discharged from the delivery port D1 of the air motor 12 is separated into two directions of A flow and B flow by the first flow divider 13. The exhaust circulation 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. As shown in FIG. 7, the exhaust circulation air is discharged to the intake port of the blower 16 that is belt-driven by the auxiliary air motor 12 through this air regulator 15, and at this time, the excess exhaust air is discarded. It is done. This increases the efficiency of the circulating exhaust air and at the same time stabilizes the circulation circuit. The blower 16 is rotationally driven by a blower motor (not shown) in addition to the belt drive.

The air sent by the blower 16 is stored in the second surging tank 17, and has a check valve provided on the outer circumference of the second air amplifier 10-2 and the third air amplifier 10-3 by the secondary flow introduction pipe N1. It is supplied to the inside through the intake hole. In other words, the structure of the second air amplifier 10-2 and the third air amplifier 10-3 is provided with a check valve 7 at each intake port, as schematically shown in FIG.

As described above, the exhaust circulation air in the A-flow direction passes through the second air amplifier 10-2 and the third air amplifier 10-3, and thus the second air amplifier 10-2 and the third air amplifier The inside of 10-3 becomes negative pressure. Therefore, the B-flow exhaust circulation air is also sucked and merged into the second air amplifier 10-2 and the third air amplifier 10-3, and the exhaust of the second air amplifier 10-2 and the third air amplifier 10-3 is exhausted. Circulating air volume increases. 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. The other of the second flow divider 19 divided in two directions is supplied with compressed air from a second compressor (stabilized compressor) 21 provided for the purpose of stabilization provided in the continuous air generation circuit R. 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 connection portion of the three-way valve 8, flows into the first air amplifier 10-1, flows into the auxiliary air motor 12, and is driven to generate power. Until the solenoid valve of the accelerator 11 is turned off, the air circulation process is repeated and the generation of power continues. The driving shaft of the second compressor 21 can be selected from driving using the power of the auxiliary air motor 12 and driving using the power of the electric motor by the battery 24.

Next, the power air circulation circuit P will be described. The entire path described below corresponds to the power circulation path in the present invention in which the air discharged from the power air motor 112 is recirculated to the power air motor 112. The configuration of each component / member in the power air circulation circuit P is almost the same as that of the auxiliary air circulation circuit Q. Therefore, the last two digits of each component in the drawing are the same as the auxiliary air circulation circuit Q. A part of the description is omitted.

In this power air circulation circuit P, the solenoid valve of the accelerator 111 is turned ON so that compressed air flows from the three-way valve 108. The compressed air is automatically controlled to 0.63 Mpa by the air control unit 109 and passes through the first air amplifier 110-1. The first air amplifier 110-1 has the same structure as that shown in FIG. The circulating air that has stored energy by increasing the air drives the power air motor 112 via the accelerator 111. As a result, the power air motor 112 rotates to generate power. The power air motor 112 has a suction port S2 and a delivery port D2, and compressed air is introduced from the suction port S2 and exhausted from the delivery port D2.

The exhaust circulation air discharged from the delivery port D2 of the air motor 112 is separated into two directions of A flow and B flow by the first flow divider 113. The exhaust circulation air in the A flow direction is stored in the first surging tank 114, and further passes through the second air amplifier 110-2 and the third air amplifier 110-3 to reach the third surging tank 118. On the other hand, the exhaust circulation air in the B flow direction reaches the air regulator 115. Through this air regulator 115, the exhaust circulation air is discharged to the intake port of the blower 116 belt-driven by the auxiliary air motor 12 on the auxiliary air circulation circuit Q side, and at this time, excess exhaust air is discarded. It is done. This increases the efficiency of the circulating exhaust air and at the same time stabilizes the circulation circuit. In addition to the belt drive, the blower 116 is rotationally driven by a blower motor (not shown) by a battery 24.

The air sent by the blower 116 is stored in the second surging tank 117, and has a check valve provided on the outer periphery of the second air amplifier 110-2 and the third air amplifier 110-3 by the secondary flow introduction pipe N2. It is supplied to the inside through the intake hole. The structures of the second air amplifier 110-2 and the third air amplifier 110-3 are the same as those shown in FIG.

As described above, the exhaust circulation air in the A-flow direction passes through the second air amplifier 110-2 and the third air amplifier 110-3, and thus, the second air amplifier 110-2 and the third air amplifier. The inside of 110-3 becomes negative pressure. Accordingly, the exhaust air circulating in the B flow is also sucked and merged into the second air amplifier 110-2 and the third air amplifier 110-3, and the exhaust air from the second air amplifier 110-2 and the third air amplifier 110-3 is exhausted. Circulating air volume increases. The increased exhaust circulation air is stored in the third surging tank 118.

The exhaust circulation air that has passed through the third surging tank 118 is supplied to one of the second flow dividers 119 divided in two directions. The other of the second shunt 119 divided in two directions is supplied with compressed air from a second compressor (stabilized compressor) 21 provided for the stabilization provided in the continuous air generating circuit R. Therefore, in the second flow divider 119, the two airs merge and are stored in the fourth surging tank 120. The air stored in the fourth surging tank 120 returns to the other connecting portion of the three-way valve 108, flows into the first air amplifier 110-1, flows into the power air motor 112, and is driven to generate power. Until the solenoid valve of the accelerator 111 is turned off, this air circulation process is repeated and the generation of power continues.

Returning to the continuous air generating circuit R, a third compressor (air-driven filling compressor) 22 is connected to the air tank 3 in order to keep the internal pressure at 0.9 MPa. Thereby, the pressure is always maintained in the air tank 3. As shown in FIG. 8, the drive shaft of the third compressor 22 is connected to the auxiliary air motor 12 by a belt, and is driven by this power. Further, the third compressor 22 includes a clutch (switching means), and can connect and disconnect the power according to the load state of the power air motor 112.

Specifically, in the present embodiment, a determination device (not shown) for determining the load state of the power air motor 112 is provided, and according to the determination result of the determination device, when the load of the power air motor 112 is high, The third compressor 22 is driven by controlling to connect the clutch. On the other hand, when the load of the power air motor 112 is low and the output is surplus, the clutch is released, the supplementation of the air tank 3 by the auxiliary air motor 12 is interrupted, and the surplus energy is used for charging the battery 24. Allocate. Thus, the driving power of the third compressor 22 effectively uses the power of the auxiliary air motor 12.

Further, the continuous air generating circuit R includes electrical components such as an alternator 23, a storage battery (battery) 24, electric filling compressors 25 and 26, and an electric motor 27. The alternator 23 is directly or indirectly connected to the output shaft of the auxiliary air motor 12 and generates electric power using this power. This power is charged in the battery 23. It is desirable that the alternator 23 and the auxiliary air motor 12 can be switched between connection and release by a clutch structure or a concept similar to the clutch.

The electric motor 27 is rotated by the power of the battery 24. As shown in FIG. 9, the electric motor 27 is connected to the electric filling compressors 25 and 26 via a coupling 27A. The electric filling compressors 25 and 26 are for filling the air tank 3 with compressed air and have a suction port S1 and a delivery port D1.

The battery 24 also rotates the blower motors of the

blowers

16 and 106. Accordingly, the energy source for maintaining the air tank 3 by moving the electric charging compressors 25 and 26, and the

blowers

16 and 106 are moved, and the exhaust air of the power air circulation circuit P and the auxiliary air circulation circuit Q is moved. It becomes an energy source for improving circulation efficiency.

In the above-described determination apparatus for determining the load state of the power air motor 112, if the load is determined to be large, the clutch between the alternator 23 and the auxiliary air motor 12 is released to stop charging the battery 23. At the same time, the clutch between the blower 116 and the auxiliary air motor 12 is connected. Further, the auxiliary air motor 12 and the battery 23 drive both of the electric filling compressors 25 and 26 and the air driven filling compressor 22 to quickly replenish the air into the air tank 3, and the blower 116. Is driven by a motor to promote air circulation.

FIG. 10 shows the configuration of the air-driven filling compressor 22. The air-driven filling compressor 22 includes an air pump 22A, a pulley 22B attached to the input shaft 22C, an electromagnetic clutch 22D for switching connection / release of the pulley 22B and the input shaft 22C, a suction port S, and a delivery port D. . A belt is stretched over the pulley 22B and connected to the auxiliary air motor 12. By switching the electromagnetic clutch 22D, driving and stopping by the auxiliary air motor 12 are switched as appropriate. Note that the same structure as the air-driven filling compressor 22 may be adopted for the second compressor 21 for stabilization.

FIG. 11 shows the configuration of the auxiliary air motor 12. The auxiliary air motor 12 includes an air pump 12A, a pulley 12B attached to the output shaft 12C, an alternator 23 connected to the shaft 12C, a suction port S1, and a delivery port D1. A belt is laid on the pulley 12B and connected to the pulley 22B of the air-driven filling compressor 22 and the like. Although the case where the alternator 23 is integrated is illustrated here, the present invention is not limited to this.

In the hybrid air circulation circuit of the present embodiment, the air recirculation and the air replenishment are hybridized, so that it is possible to flexibly cope with the load of the external output, thereby further improving the air utilization efficiency. It becomes possible. In particular, the power air circulation circuit P side is not used as a power source for the continuous air generation circuit R, so that the output of the power air circulation circuit P is always stabilized. On the other hand, by using the auxiliary air circulation circuit Q as a power source of the continuous air generation circuit R, the air tank 3 can secure a stable air pressure.

Although not specifically shown, the battery 24 is provided with a plug-in outlet for home power supply so that it can be charged by the home power supply.

Next, the first to third air amplifiers 10-1, 10-2 and 10-3 of the auxiliary air circulation circuit Q and the first to third air amplifiers 110-1 and 110-2 of the power air circulation circuit P are used. , 110-3 will be described in detail. In the following, five types of

air amplifiers

601, 201, 301, 401, and 501 will be described, and the optimum one among these air amplifiers 201 to 601 will be selected and the first to third air amplifiers 10-1 will be described. It may be applied to all of 10-2, 10-3, 110-1, 110-2, 110-3, or may be partially applied. Further, as will be described later, for example, the air amplifier 601 of the first example has a two-stage amplification structure, so that the above-described second and third amplifiers 10-2, 10- are provided by one air amplifier 601. 2, 110-2, 110-3 may be realized simultaneously. The air amplifier described below has a structure in which air, compressed air, gas, or the like is efficiently sucked by a plurality of air suction ports provided on the outer periphery of the air amplifier.

12 and 13 show an air amplifier 601 according to the first example. The amplifier 601 includes a passage 610 that is formed inside and through which the main airflow passes. A first chamber 612, a second chamber 614, and a third chamber 616 serving as a branch chamber are disposed along the main air flow in the passage route 610. Each of the

compartments

612, 614, 616 is constituted by cylindrical

outer walls

612A, 614A, 616A. In the first chamber 612, a passage hole 612B that discharges air to the second chamber 614 side is formed. In the second chamber 614, a passage hole 614B for discharging air to the third chamber 616 side is formed. In the third chamber 616, a passage hole 616B for discharging air to the outside is formed. Note that the first chamber 612, the second chamber 614, and the third chamber 616 are entirely molded integrally.

Further, the inner diameter d2 of the second chamber 614 is larger than the inner diameter d1 of the first chamber 612. Furthermore, the inner diameter d3 of the third chamber 616 is larger than the inner diameter d2 of the second chamber 614. 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 614B in the second chamber 614 is set larger than the inner diameter d4 of the passage hole 612B in the first chamber 612, and the third inner diameter is larger than the inner diameter of the passage hole 614B in the second chamber 614. The inner diameter of the passage hole 616B in the chamber 616 (this coincides with the inner diameter d3 of the third chamber 616) is set large.

A tapered throttle portion 612C having a path diameter that decreases in the discharge direction is provided on the discharge side in the first chamber 612. Therefore, the passage hole 612B is disposed at the protruding end of the throttle portion 612C. Similarly, on the discharge side in the second chamber 614, a tapered throttle portion 614C having a path diameter that decreases in the discharge direction is provided. Therefore, the passage hole 614B is disposed at the protruding end of the throttle portion 614C. By these throttle parts 612C and 614C, the flow rate of air is increased and the efficiency of generating internal negative pressure is increased. The third chamber 616 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 610. Specifically, in the vicinity of the boundary with the first chamber 612 on the outer periphery of the second chamber 614, four second chamber air suction ports 614D are arranged at intervals of 90 degrees in the circumferential direction. In addition, four third chamber air suction ports 616D are arranged at intervals of 90 degrees in the circumferential direction near the boundary with the second chamber 614 on the outer periphery of the third chamber 616. When the main air flow passes through the passage 610, the pressure in the second chamber 614 becomes negative, air is sucked from the second chamber air suction port 614D, and merges with the passage 610. Similarly, when the main air flow passes through the passage 610, the inside of the third chamber 616 becomes negative pressure, air is sucked from the third chamber air suction port 616D, and merges with the passage 610.

The air suction port 614D for the second chamber is disposed along the outer wall of the throttle portion 612C in the first chamber 612 using its tapered shape. At this time, the air suction port 614D for the second chamber merges with an acute angle α with respect to the flow direction of the main air flow in the passage route 610. Similarly, the air suction port 616D for the third chamber is disposed along the outer wall of the throttle portion 614C in the second chamber 614 using its tapered shape. At this time, the air suction port 616D for the third chamber merges with an acute angle α with respect to the flow direction of the main air flow in the passage route 610. Thus, by joining at an acute angle α, the resistance at the time of joining is reduced, and the amplification efficiency is increased.

Next, the air amplifier 201 according to the second example will be described with reference to FIG. In the second example, parts different from the air amplifier 601 of the first example will be mainly described, and the same or similar parts will be described and illustrated by matching the last two digits of the reference numerals with the first example. Is 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 example will be described with reference to FIG. In this third example, parts different from the air amplifier 601 of the first example will be mainly described, and the same or similar parts will be described and illustrated by matching the last two digits of the reference numerals with the first example. Is 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 312F are further provided around the passage hole 312B 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 example will be described with reference to FIG. In the fourth example, parts different from the air amplifier 601 of the first example will be mainly described, and the same or similar parts will be described and illustrated by matching the last two digits of the reference numerals with the first example. Is 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 example, and thus description thereof is 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. 17, 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.

Next, an air amplifier 501 according to a fifth example will be described with reference to FIG. In the fifth example, parts different from the air amplifier 601 of the first example will be mainly described, and the same or similar parts will be described and illustrated by matching the last two digits of the reference numerals with the first example. Is omitted.

In the air amplifier 501, the first chamber 512 and the second chamber 514 can be separated. Further, the inner diameter d2 of the second chamber 514 is smaller than the inner diameter d1 of the first chamber 512. Thus, the flow velocity is increased by reducing the inner diameter of the compartment toward the downstream side. On the other hand, the passage hole 512B of the first chamber 512 is thinner than the diameter of the second chamber 514 on the downstream side. Further, here, the passage hole 512B itself has a tapered shape that becomes gradually thinner toward the downstream side, so that the flow velocity of the air is increased. Further, an air suction slit 514E having a ring shape is disposed around the outlet of the passage hole 512B by utilizing a step due to the difference in diameter between the passage hole 512B and the second chamber 514. Further, a plurality (eight in this case) of air suction ports 514D are arranged at equal intervals in the circumferential direction in the air suction slit 514E.

Main air flow is discharged to the second chamber 514 side through the passage hole 512B. As a result, the air amplification efficiency can be increased. On the downstream side of the second chamber 514, a diffuser 514F whose diameter gradually increases is provided.

Furthermore, a check valve (check valve) 514G is installed in each air suction port 514D. 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.

As described above, the hybrid air circulation circuit according to the present embodiment makes it possible to store energy in the battery 24 using the output when the compressed air filled in the air tank 3 is converted into power. Further, the electric power of the battery 24 can be used to replenish compressed air to the air tank 3 and to operate the blowers 16 and 116. Therefore, the air circulation circuit generally has a drawback that it is difficult to flexibly cope with fluctuations in the external load. However, the hybridization can flexibly deal with fluctuations in the external load and use compressed air. Efficiency can be increased.

Particularly, in this embodiment, when the continuous air generating circuit R is hybridized, two systems of a power air circulation circuit P and an auxiliary air circulation circuit Q are prepared. Therefore, the power air circulation circuit P can be further stabilized by using the output of the auxiliary air circulation circuit Q for driving and charging the continuous air generation circuit R.

In particular, for example, when the load of the power air motor 112 is high, replenishment of compressed air using the battery 24 and replenishment of compressed air using the auxiliary air motor 12 are performed simultaneously in order to increase the supplied air pressure. By doing so, a reduction in driving force of the power air motor 112 is suppressed. On the other hand, when the load of the power air motor 112 is light, the surplus power of the auxiliary air motor 12 can be stored in the battery 24 via the alternator 23 to prepare for the next high load.

As described above, the present embodiment shows the case where the

check valves

7 and 107 are arranged in the air supply path before the three-

way valves

8 and 108 in the power air circulation circuit P and the auxiliary air circulation circuit Q, respectively. However, for example, the three-

way valves

8 and 108 themselves give priority to the high pressure in comparison with the compressed air sent from the air tank 3 and the air sent from the

fourth surge tanks

20 and 120. The

check valves

7 and 107 are not necessary if a device having a function for sending to 9, 109 is used. On the other hand, it is also preferable to arrange a T-shaped pipe in place of the three-

way valves

8 and 108 and provide the

check valves

7 and 107 in each of the air supply paths. If the higher pressure is given priority in this way and the air is sent in the next direction, air circulation can be performed effectively.

¡By installing a rechargeable battery, the air circulation circuit for using the air motor as power can be operated more effectively. Moreover, air motor rotational power can be easily obtained by effectively providing an air amplifier on the air circulation circuit. Furthermore, the output of the power air circulation circuit is stabilized by providing an auxiliary air circulation circuit as a power source for the hybrid as 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.
