　本発明では、エアー循環回路に対して、蓄電池とオルタネータ等を中心とした電装回路を組み込むことにより、動力用エアーモータの外部出力の低下を抑制する。具体的には、動力用エアーモータの出力を常に安定した状態に維持するために、蓄電池を電源した電動モータを利用して充填用コンプレッサを動作させる。この結果、動力用エアーモータの負荷が大きくても、エアータンクの圧力低下を抑制できる。なお、通常は、動力用エアーモータの出力を使用してエアー駆動式充填用コンプレッサを駆動して、エアータンクへのエアーの補充をおこなうが、動力用エアーモータの負荷が大きい場合は、コンプレッサを停止させて、代わりにバッテリーの電力を使用した電動モータによって電動式充填用エアーコンプレッサで、エアータンクのエアーの補充を行う。この結果、エアータンクの圧力も安定させることができるので、この相乗効果によって、動力用エアーモータの出力を一層安定させることが可能となる。また本発明によれば、適切にエアー増幅器を配備することで、エアーの効率を上げることができる。 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 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. Normally, the air-driven filling compressor is driven using the output of the power air motor to replenish air to the air tank. However, if the load on the power air motor is heavy, the compressor should be turned on. The air tank is refilled with an electric filling air compressor using an electric motor that uses battery power instead. As a result, the pressure of the air tank can be stabilized, and this synergistic effect can further stabilize the output of the power air motor. Further, according to the present invention, it is possible to increase the efficiency of air by appropriately providing an air amplifier.
　本発明では、エアー循環回路をハイブリッド化することにより、動力用エアーモータから出力される動力の安定化を図ることができるようになる。 In the present invention, the power output from the power air motor can be stabilized by hybridizing the air circulation circuit.

　本発明の実施形態では、エアー循環回路を円滑且つ効率的に動作させるため、動力用エアーモータの負荷の大きさに応じて、エアータンクのエアーの補充を、エアーモータの出力を使用したコンプレッサと、蓄電池の電力を使用した電動モータで駆動するエアーコンプレッサとで使い分けるようにしている。これにより、一層安定化したエアーモータの動力を得るようにしている。また、エアー増幅器の開発も併せて行っている。以下詳細に説明する。 In the embodiment of the present invention, in order to operate the air circulation circuit smoothly and efficiently, the air tank is replenished with a compressor using the output of the air motor in accordance with the load of the power motor. The air compressor driven by an electric motor using the power of the storage battery is used properly. As a result, more stable power of the air motor is obtained. We are also developing air amplifiers. This will be described in detail below.
　図１は、本発明の実施形態であって、１～２７の部品構成を備えて構成されるハイブリッド・エアー循環回路である。ここでは、各部品構成の説明と同時に、ハイブリッド・エアー循環回路の動作についても説明する。このハイブリッド・エアー循環回路は、エアー循環回路Ｐと連続エアー発生回路Ｒを備えて構成される。なお、図２及び図３には、このハイブリッド・エアー循環回路の作動状態を示すフローチャートが示されている。 FIG. 1 shows an embodiment of the present invention, which is a hybrid air circulation circuit having a component configuration of 1 to 27. Here, the operation of the hybrid air circulation circuit will be described at the same time as the description of each component configuration. This hybrid air circulation circuit includes an air circulation circuit P and a continuous air generation circuit R. 2 and 3 are flowcharts showing the operating state of the hybrid air circulation circuit.
　連続エアー発生回路Ｒでは、動力用エアーモーター１２を動力として活用するにあたり、起動の前準備として、最初に起動用に用いる圧縮エアーを得るため準備用コンプレッサー１を起動して、エアーチャージバルブ２を用いてエアータンク３に０．９Ｍｐａの圧縮空気を初期充填する。次いで、エアーストップバルブ６を開くことで、圧縮エアーを、エアー循環回路Ｐの３方バルブ８に至らしめる。なお、エアータンク３には、開閉バルブ４及び圧力ゲージ５が設けられている。 In the continuous air generation circuit R, in order to use the power air motor 12 as power, the preparation compressor 1 is first activated in order to obtain the compressed air to be used for activation first, and the air charge valve 2 is activated. The air tank 3 is initially filled with 0.9 Mpa of compressed air. Next, the air stop valve 6 is opened to bring the compressed air to the three-way valve 8 of the air circulation circuit P. The air tank 3 is provided with an opening / closing valve 4 and a pressure gauge 5.
　次にエアー循環回路Ｐについて説明する。なお、以下に説明する経路全体が、動力用エアーモータ１２から排出されたエアーをこの動力用エアーモータ１２に再循環させる本発明における循環経路に相当する。まず、アクセレレーター１１のソレノイドバルブをＯＮにして、３方バルブ８から圧縮エアーが流れるようにする。この圧縮エアーは、エアーコントロールユニット９によって自動的に０．６３Ｍｐａに制御され、第１エアー増幅器１０－１を通過する。この第１エアー増幅器１０－１は、図４に概略構成が示されるように、圧縮エアーの通過によって内部が負圧となり、その負圧によって外気が流入する構造となっている。各流入孔にはチェックバルブ７が設けられており、逆流を防止している。この結果、第１エアー増幅器１０－１では、エアー流量が約１０倍に増加する。その増加に関しは、表１において、エアー増幅器入口のエアー量と出口のエアー増加量の状態で示した。エアー増加でエネルギーを蓄えた循環エアーはアクセレレーター１１を経て動力用エアーモーター１２を駆動する。これにより動力用エアーモーター１２が回転して動力を発生する。なお、この動力用エアーモータ１２は、サクションポートＳ１とデリバリーポートＤ１を有しており、サクションポートＳ１から圧縮エアーが導入されて、デリバリーポートＤ１から排気される。

 Next, the air circulation circuit P will be described. Note that the entire path described below corresponds to the circulation path in the present invention in which the air discharged from the power air motor 12 is recirculated to the power air motor 12. First, 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. 4, the first air amplifier 10-1 has a structure in which a negative pressure is caused by passage of compressed air, and 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 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 power air motor 12 via the accelerator 11. As a result, the power air motor 12 rotates to generate power. The power 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.
Figure JPOXMLDOC01-appb-T000001
　エアーモーター１２のデリバリーポートＤ１から吐出された排気循環エアーは、第１分流器１３によりＡフロー及びＢフローの２方向に別れる。Ａフロー方向の排気循環エアーは、第１サージングタンク１４に蓄えられ、更に、第２エアー増幅器１０－２及び第３エアー増幅器１０－３を通り第３サージングタンク１８に至る。一方、Ｂフロー方向の排気循環エアーは、エアーレギュレーター１５に至る。このエアーレギュレータ１５を介して、排気循環エアーは、図６に示されるように、動力用エアーモーター１２によってベルト駆動されているブロワー１６の吸気ポートに排出されて、この時余分の排気エアーは捨てられる。これにより、循環排気エアーの効率を高めると同時に、循環回路の安定化の動きをするものである。なお、このブロワー１６は、ベルト駆動の他に、特に図示しないブロワ用モータによって回転駆動されるようになっている。 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. 6, the exhaust circulation air is discharged to the intake port of the blower 16 that is belt-driven by the power air motor 12 through the 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.
　ブロワー１６で送られたエアーは、第２サージングタンク１７に蓄えられ、配管により、第２エアー増幅器１０－２及び第３エアー増幅器１０－３の外周に配備されたチェックバルブ付吸気孔を介して内部に供給される。即ち、第２エアー増幅器１０－２及び第３エアー増幅器１０－３の構造は、図５に概略構成が示されるように、各吸気口にチェックバルブ７が設置される。 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 a pipe via an intake hole with a check valve. Supplied inside. That is, 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.
　既に述べたように、Ａフロー方向の排気循環エアーは、第２エアー増幅器１０－２及び第３エアー増幅器１０－３の内部を通るので、これにより第２エアー増幅器１０－２及び第３エアー増幅器１０－３の内部は負圧になる。従ってこのＢフローの排気循環エアーも第２エアー増幅器１０－２及び第３エアー増幅器１０－３内に吸引・合流されていき、第２エアー増幅器１０－２及び第３エアー増幅器１０－３の排気循環エアー量は増加する。増加した排気循環エアーは第３サージングタンク１８に蓄えられる。 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.
　第３サージングタンク１８を経た排気循環エアーは、第２分流器１９の２方向に分かれた一方に供給される。また、第２分流器１９の２方向に分かれた他方には、安定化を目的とした第２コンプレッサー（安定化コンプレッサー）２１の圧縮エアーが供給される。従って、第２分流器１９では、この２つのエアーが合流して第４サージングタンク２０に蓄えられる。第４サージングタンク２０に蓄えられたエアーは、３方バルブ８の他方の接続部分に戻り、第１エアー増幅器１０－１に流れ込み、動力用エアーモーター１２に流れて駆動し動力を発生する。アクセレレーター１１のソレノイドバルブをＯＦＦにするまで、エアー循環工程が繰返し、動力の発生が続けられる。なお、この第２コンプレッサー２１の駆動軸は、動力用エアーモータ１２の動力を利用した駆動と、バッテリー２４による電動モータの動力による駆動を選択できるようになっている。 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 for the purpose of stabilization. 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 power 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 drive shaft of the second compressor 21 can be selected from driving using the power of the power air motor 12 and driving using the power of the electric motor by the battery 24.
　また、エアータンク３には、その内部圧力を０．９Ｍｐａに保つため、第３コンプレッサー（エアー駆動式充填用コンプレッサ）２２が接続されている。これにより、エアータンク３は、常に圧力が維持されている。図７に示されるように、この第３コンプレッサー２２の駆動軸は、ベルトによって動力用エアーモータ１２に接続されており、この動力によって駆動されている。さらにこの第３コンプレッサ２２はクラッチ（切替手段）を備えており、動力用エアーモータ１２の負荷状態に応じて、動力の接続と切断が行える。具体的に本実施形態では、動力用エアーモータ１２の負荷状態を判定する判定装置（図示省略）を備えており、この判定装置の判定結果により、動力用エアーモータ１２の負荷が高い場合は、クラッチを開放するように制御して、第３コンプレッサ２２を停止させる。一方、動力用エアーモータ１２の負荷が低く、出力に余剰がある場合は、クラッチを接続してエアータンク３の補充にエネルギーを割り当てる。このように、第３コンプレッサー２２の駆動動力は、動力用エアーモーター１２の余剰動力を効果的に利用している。 In addition, 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. 7, the drive shaft of the third compressor 22 is connected to the power 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 power according to the load state of the power air motor 12. Specifically, in the present embodiment, a determination device (not shown) that determines the load state of the power air motor 12 is provided. According to the determination result of the determination device, when the load of the power air motor 12 is high, The third compressor 22 is stopped by controlling to release the clutch. On the other hand, when the load of the power air motor 12 is low and the output is surplus, the clutch is connected and energy is allocated to the replenishment of the air tank 3. As described above, the driving power of the third compressor 22 effectively uses surplus power of the power air motor 12.
　更にこのハイブリッド・エアー循環回路は、オルタネータ２３、蓄電池（バッテリー）２４、電動式充填用コンプレッサ２５、２６、電動モータ２７等の電装部品を備えている。オルタネータ２３は、直接又は間接的に動力用エアーモータ１２の出力軸に接続されており、この動力によって発電する。この電力はバッテリー２３に充電される。オルタネータ２３と動力用エアーモータ１２の間にも、クラッチ構造又はクラッチに準ずる構想によって接続と開放を切り替えることができるようにすることが望ましい。
電動モータ２７は、バッテリー２４の電力によって回転する。図８に示されるように、この電動モータ２７は、電動式充填用コンプレッサ２５、２６にカップリング２７Ａを介して接続されている。この電動式充填用コンプレッサ２５、２６は、エアータンク３に圧縮エアーを充填するものであり、サクションポートＳ１とデリバリーポートＤ１を有している。 The hybrid air circulation circuit further includes electrical components such as an alternator 23, a storage battery (battery) 24, electric charging compressors 25 and 26, and an electric motor 27. The alternator 23 is directly or indirectly connected to the output shaft of the power air motor 12 and generates power using this power. This power is charged in the battery 23. It is desirable that the alternator 23 and the power air motor 12 can be switched between connection and release according to 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. 8, 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.
　なお、このバッテリー２４は、ブロワー１６のブロワ用モータも回転させる。従って、電動式充填用コンプレッサ２５、２６を動かしてエアータンク３を維持するためのエネルギー源と、ブロワー１６を動かして排気エアーの循環効率を高めるためのエネルギー源となる。 The battery 24 also rotates the blower motor of the blower 16. Therefore, it becomes an energy source for moving the electric filling compressors 25 and 26 to maintain the air tank 3 and an energy source for moving the blower 16 to increase the circulation efficiency of the exhaust air.
　既に述べた動力用エアーモータ１２の負荷状態を判定する判定装置において、負荷が大きいと判定される場合は、オルタネータ２３と動力用エアーモータ１２の間のクラッチを開放してバッテリー２３の充電を中止すると共に、ブロワー１６と動力用エアーモータ１２の間のクラッチも開放する。一方、バッテリー２３によって、電動式充填用コンプレッサ２５、２６を駆動してエアータンク３へのエアーの補充を行うと共に、ブロワー１６をモータによって駆動してエアー循環を促す。このように、エアーの再循環とエアーの補充をハイブリッド化することによって、外部出力の負荷に柔軟に対応できるようにすることで、エアーの利用効率を更に高めることが可能となる。 In the above-described determination apparatus for determining the load state of the power air motor 12, if it is determined that the load is large, the clutch between the alternator 23 and the power air motor 12 is released to stop charging the battery 23. At the same time, the clutch between the blower 16 and the power air motor 12 is also released. On the other hand, the battery 23 drives the electric filling compressors 25 and 26 to replenish air to the air tank 3, and the blower 16 is driven by a motor to promote air circulation. As described above, by hybridizing the air recirculation and the air replenishment, it is possible to flexibly cope with the load of the external output, thereby further improving the air utilization efficiency.
　なお特に図示しないが、このバッテリー２４には、家庭用電源のプラグインコンセントが用意されており、家庭用電源によっても充電できるようになっている。 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.
　次に、第１～第３エアー増幅器１０－１、１０－２、１０－３の詳細構造について説明する。なお、ここでは５種類のエアー増幅器１０１～５０１を説明することにする。エアー増幅器１０１～５０１から最適なものを選択して、第１～第３エアー増幅器１０－１、１０－２、１０－３の全てに適用してもよく、また部分的に適用しても良い。また、後述の通り、例えば第１例のエアー増幅器１０１等については２段の増幅構造となっていることから、１台のエアー増幅器１０１によって、上述の第２，第３増幅器１０－２、１０－２を実現しても良い。以下で説明するエアー増幅器は、自身の外周に備えた複数個のエアー吸入ポートによって、大気、圧縮エアーあるいは気体等を効率良く吸入する構造となっている。 Next, the detailed structure of the first to third air amplifiers 10-1, 10-2, 10-3 will be described. Here, five types of air amplifiers 101 to 501 will be described. The optimum air amplifiers 101 to 501 may be selected and applied to all of the first to third air amplifiers 10-1, 10-2, and 10-3, or may be partially applied. . Further, as will be described later, for example, the air amplifier 101 in the first example has a two-stage amplification structure, so that the above-described second and third amplifiers 10-2, 10-2, -2 may be realized. 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.
　図９及び図１０には、第１例にかかるエアー増幅器１０１が示されている。この増幅器１０１は、内部に形成されてメインエアーフローが通過する通過経路１１０を備える。この通過経路１１０には、メインエアーフローに沿って、分室となる第１室１１２、第２室１１４、第３室１１６が配置されている。各分室１１２、１１４、１１６は円筒状の外壁１１２Ａ、１１４Ａ、１１６Ａによって構成されている。第１室１１２には、第２室１１４側にエアーを吐出する通過孔１１２Ｂが形成されている。第２室１１４には、第３室１１６側にエアーを吐出する通過孔１１４Ｂが形成されている。第３室１１６には、外部にエアーを吐出する通過孔１１６Ｂが形成されている。なお、これらの第１室１１２、第２室１１４、第３室１１６は、全体が一体的に成型されている。 9 and 10 show the air amplifier 101 according to the first example. 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.
　また、第１室１１２の内径ｄ１に対して、第２室１１４の内径ｄ２の方が大きくなっている。更に、第２室１１４の内径ｄ２に対して、第３室１１６の内径ｄ３の方が大きくなっている。このように、下流側に向かって分室の内径を増大させていくことで、増幅効率を高めている。また、この段差を利用して、後述するエアー吸入ポートを配置することで、合理的な形状で外側からのエアーの吸引を実現している。 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.
　更に、第１室１１２の通過孔１１２Ｂの内径ｄ４に対して、第２室１１４における通過孔１１４Ｂの内径は大きく設定され、また、第２室１１４の通過孔１１４Ｂの内径に対して、第３室１１６における通過孔１１６Ｂの内径（これは第３室１１６の内径ｄ３と一致）が大きく設定されている。 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.
　第１室１１２における吐出側には、吐出方向に向かって経路直径が小さくなるテーパ形状の絞り部１１２Ｃが設けられている。従って、この絞り部１１２Ｃの突端に通過孔１１２Ｂが配置されていることになる。同様に、第２室１１４における吐出側には、吐出方向に向かって経路直径が小さくなるテーパ形状の絞り部１１４Ｃが設けられている。従って、この絞り部１１４Ｃの突端に通過孔１１４Ｂが配置されている。これらの絞り部１１２Ｃ、１１４Ｃによって、エアーの流速を増大させて、内部の負圧の発生効率を高める。なお、第３室１１６には絞り部は形成されていない。下流側に負圧を発生させる必要がないからである。 A tapered throttle portion 112C having a path diameter that decreases in the discharge direction is provided on the discharge side in the first chamber 112. 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.
　通過経路１１０の外周には、エアー吸入ポートが複数配置されている。具体的に、第２室１１４の外周における第１室１１２との境界近傍には、周方向に９０度間隔で、４つの第２室用エアー吸入ポート１１４Ｄが配置されている。また、第３室１１６の外周における第２室１１４との境界近傍には、周方向に９０度間隔で、４つの第３室用エアー吸入ポート１１６Ｄが配置されている。通過経路１１０内をメインエアーフローが通過すると、第２室１１４内が負圧となって、第２室用エアー吸入ポート１１４Ｄからエアーが吸入されて、この通過経路１１０に合流する。同様に、通過経路１１０内をメインエアーフローが通過すると、第３室１１６内が負圧となって、第３室用エアー吸入ポート１１６Ｄからエアーが吸入されて、この通過経路１１０に合流する。 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.
　この第２室用エアー吸入ポート１１４Ｄは、第１室１１２における絞り部１１２Ｃの外壁に沿って、そのテーパ形状を利用して配置される。この際、第２室用エアー吸入ポート１１４Ｄは、通過経路１１０のメインエアーフローの流れ方向に対して鋭角αを持って合流するようになっている。同様に、この第３室用エアー吸入ポート１１６Ｄは、第２室１１４における絞り部１１４Ｃの外壁に沿って、そのテーパ形状を利用して配置される。この際、第３室用エアー吸入ポート１１６Ｄは、通過経路１１０のメインエアーフローの流れ方向に対して鋭角αを持って合流する。このように、鋭角αで合流することで、合流時の抵抗を低減して、増幅効率を高めるようにしている。 The air suction port 114D for the second chamber is arranged 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.
　次に、図１１を参照して、第２例にかかるエアー増幅器２０１を説明する。なお、この第２例では、第１例のエアー増幅器１０１と異なる部分について主に説明し、同一又は類似する部分については、符号の下二桁を第１例と一致させることで、説明及び図示を省略する。 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 101 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.
　このエアー増幅器２０１は、第１室２１２、第２室２１４、第３室２１６に加えて、第４室２１８を備えている。従って、特に図示しないが、第３室２１６にも、直径がテーパ状に細くなった状態の絞り部が形成されており、この突端の通過孔から第４室２１８にエアーが排出される。第４室２１８の外周には、第４室用エアー吸入ポート２１８Ｄが形成されており、エアーを吸入して更に増幅させる。このように、通過経路２１０上の分室の数を増やすことで、増幅量を増大させることができる。 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.
　次に、図１２を参照して、第３例にかかるエアー増幅器３０１を説明する。なお、この第３例では、第１例のエアー増幅器１０１と異なる部分について主に説明し、同一又は類似する部分については、符号の下二桁を第１例と一致させることで、説明及び図示を省略する。 Next, an air amplifier 301 according to a third example will be described with reference to FIG. In the third example, parts different from the air amplifier 101 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.
　このエアー増幅器３０１は、第１室３１２、第２室３１４、第３室３１６が、分離可能になっている。詳細には、第２室３１４の上流側に円筒状の係合部３１４Ｅが形成されており、その係合部３１４Ｅ内に第１室３１２が挿入されることで、着脱可能に相互に嵌めあうようになっている。第３室３１６の上流側にも円筒状の係合部３１６Ｅが形成されており、その係合部３１６Ｅ内に第２室３１４が挿入されることで、着脱可能に相互に嵌めあう。このように、第１室３１２から第３室３１６の間に形成される段差を有効活用し、入れ子状に嵌めあわせることで、分解や組み立てが容易にしている。この結果、メンテナンスも簡便になる。 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.
　このエアー増幅器３０１では、第１室３１２の通過孔３１２Ｂの周囲に、更に複数の補助孔３１２Ｆが設けられている。この補助孔３１２Ｆも、エアーを通過可能であり、通過孔３１２Ｂ及び補助孔３１２Ｆの双方を介してメインエアーフローが第２室３１４側に吐出される。この結果、エアーの増幅効率を高めることが可能になる。 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.
　次に、図１３を参照して、第４例にかかるエアー増幅器４０１を説明する。なお、この第４例では、第１例のエアー増幅器１０１と異なる部分について主に説明し、同一又は類似する部分については、符号の下二桁を第１例と一致させることで、説明及び図示を省略する。 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 101 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.
　このエアー増幅器４０１は、通過経路４１０が分室に分かれていない一体構造となっている。なお、この通過経路４１０の入口近傍には、絞り部４１０Ａが配置されており、流入したエアーをいったん絞って、流速を高めるようにしている。また、この通過経路４１０における絞り部４１０Ａの下流側は、エアー進入側からエアー放出側に向かって次第に大きくなるテーパー形状となっている。従って、その入口側の直径ｄ６に対して、出口側の直径ｄ７は大きくなっている。また、このテーパー形状の通過経路４１０の外周には、軸方向に一定の間隔を空けて、第１エアー吸入ポート４１０Ｂ、及び第２エアー吸入ポート４１０Ｃが配置されている。なお、エアー吸入ポート４１０Ｂ、４１０Ｃの構造及び機能については、第１例のエアー吸入ポートと同様であるので説明を省略する。このように、通過経路４１０の内径を滑らかに増大させることで、エアーの流れ抵抗が低減され、増幅効率を高めることが可能となる。 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.
　なお、このテーパー形状の通過経路４１０の内周壁には、図１４に示されるように、複数条の溝４１０Ｄを形成することの望ましい。このスパイラル状の溝４１０Ｄによって、メインエアーフローにスワールを生じさせて、増幅効率を向上させる。 In addition, as shown in FIG. 14, 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.
　次に、図１５を参照して、第５例にかかるエアー増幅器５０１を説明する。なお、この第５例では、第１例のエアー増幅器１０１と異なる部分について主に説明し、同一又は類似する部分については、符号の下二桁を第１例と一致させることで、説明及び図示を省略する。 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 101 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.
　このエアー増幅器５０１は、第１室５１２、第２室５１４が分離可能になっている。また、第１室５１２の内径ｄ１に対して、第２室５１４の内径ｄ２の方が小さくなっている。このように、下流側に向かって分室の内径を縮小させていくことで、流速を高めるようにしている。一方、第１室５１２の通過孔５１２Ｂは、下流側の第２室５１４の直径よりも細くなっている。更にここでは、この通過孔５１２Ｂ自体が、下流側に進むにつれて次第に細くなるテーパ形状となっており、エアーの流速が高まるようになっている。また、通過孔５１２Ｂと第２室５１４の直径が異なることによる段差を利用して、通過孔５１２Ｂの出口の周囲に、リング形状となるエアー吸入スリット５１４Ｅが配置されている。更にこのエアー吸入スリット５１４Ｅには、複数（ここでは８つ）のエアー吸入ポート５１４Ｄが周方向に等間隔で配置される。 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.
　通過孔５１２Ｂを介してメインエアーフローが第２室５１４側に吐出される。この結果、エアーの増幅効率を高めることが可能になる。第２室５１４の下流側は、直径が次第に広くなるデフューザ５１４Ｆが設けられている。 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.
　更に各エアー吸入ポート５１４Ｄには、逆止弁（チェックバルブ）５１４Ｇが設置されている。このようにすることで、エアー吸入ポートから通過経路に向かうエアーの流れは許容し、その反対の流れは抑制することで、一層、増幅の推進力を向上させることができる。 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.
　以上、本実施形態のハイブリッド・エアー循環回路は、エアータンク３に充填された圧縮エアーを動力に変換する際に、その出力を利用してバッテリー２４にエネルギーを蓄えることを可能にしている。また、このバッテリー２４の電力を利用して、エアータンク３への圧縮エアーの補充を行ったり、ブロアー１６を動作させたりすることができる。従って、エアー循環回路では、一般的に、外部負荷の変動に柔軟に対応できないという欠点があるが、このようにハイブリッド化することによって、外部負荷の変動に柔軟に対応でき、圧縮エアーの利用効率を高めることが出来る。 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 power of the battery 24 can be used to replenish the air tank 3 with compressed air or to operate the blower 16. Therefore, the air circulation circuit generally has a drawback that it cannot flexibly cope with fluctuations in external load. However, by using such a hybrid, it can flexibly deal with fluctuations in external load and use efficiency of compressed air. Can be increased.
　具体的には、動力用エアーモータ１２の負荷が高いときは、この動力によるバッテリー２４の充電を行わないようにし、更に、このバッテリー２４を利用した圧縮エアーの補充を行うことで、動力用エアーモータ１２の動力低下が生じないようにする。一方で、動力用エアーモータ１２の負荷が軽いときは、その余剰動力をオルタネータ２３を介してバッテリー２４に蓄えるようにして、次の高負荷時に備えることができる。 Specifically, when the load of the power air motor 12 is high, the battery 24 is not charged by the power, and further, the replenishment of compressed air using the battery 24 is performed, so that the power air The power of the motor 12 is not reduced. On the other hand, when the load of the power air motor 12 is light, the surplus power can be stored in the battery 24 via the alternator 23 to prepare for the next high load.
