【発明の詳細な説明】内燃機関吸入システム用の一体型ウェーブデフレクタ発明の背景および要約本発明は、内燃機関（１，Ｃ０）の吸入システム、特に、個々のシリンダへの調整ランチ内に用いられる新規なウェーブデフレクタに関するものである。[Detailed description of the invention] Integrated type for internal combustion engine intake system wave deflector Background and summary of the invention The invention relates to the intake system of an internal combustion engine (1, C0), in particular to the adjustment to the individual cylinders. This invention relates to a novel wave deflector for use in a regular launch.

内燃機関吸入システムの公知構造には、個別シリンダへ導かれる調整ランナと、このう、ンナと組合されて配置されたウェーブデフレクタとが含まれている。一般的に言える点は、複数ウェーブデフレクタを選択的に操作して、一定の操作条件のものとで特定のランナ・セットを選外に置くことができ、その結果、空気が、別様に調整されたランチ・セットを通ってシリンダへ送られるという点である。独立的に操作可能なウェーブデフレクタが各ランチ・セットと組合されて備えられている場合は、その各ランナ・セットを個別に選択から外すことができる。Known constructions of internal combustion engine intake systems include regulating runners leading to the individual cylinders; The wave deflector also includes a wave deflector arranged in combination with the deflector. one Generally speaking, multiple wave deflectors can be selectively operated to achieve certain operating conditions. Certain sets of runners can be excluded from the , in that it is sent to the cylinder through a differently prepared lunch set. . An independently operable wave deflector is provided in conjunction with each launch set. If so, you can deselect each runner set individually.

ウェーブデフレクタは、一つのランナのシリンダ端部のところで平行を保っている。ウェーブデフレクタは、また、開閉位置に操作可能で、組合されたランチを開閉する。一つのランナを選択から外されるのは、組合されたウェーブデフレクタが閉じられたときである。閉じられたウエーブデフレクタは、シリンダ内のピストンが吸入行程を行っているときに、対応シリンダから出る圧力波を阻止又は偏向させる。The wave deflector remains parallel at the cylinder end of one runner. Ru. The wave deflector is also operable into open and closed positions, allowing the combined launch Open and close. One runner is deselected because the combined wave deflection when the data is closed. The closed wave deflector Block or block the pressure waves coming out of the corresponding cylinder when the stone is on the suction stroke. deflect.

ウェーブデフレクタ用の公知構造は、金属シャフトを有しおり、この金属シャフトが、隣接のシリンダに延びる各ランナを分離する壁内の、整列された円形の穴を貫通している。デフレクタを形成する金属製のブレードは、このシャフトに取付けられている。この構造は、しかし、出費が大きい。なぜなら、多くの個別部品を使用し、かなりの数の組立て部品を必要とするからである。更に、部品の一つが破損したりすれば、その破片がエンジンシリンダ内へ入り込み、望ましくない結果を引き起こす。Known constructions for wave deflectors have a metal shaft, which Aligned circular holes in the wall separating each runner where the runners extend into adjacent cylinders. penetrates through. The metal blades forming the deflector are attached to this shaft. It is attached. This structure, however, is costly. Because many individual parts This is because it uses many parts and requires a considerable number of assembled parts. Furthermore, one of the parts If the cause bad results.

本発明は、圧力波を偏向させる目的にとっては、組合されたランチにウェーブデフレクタを精密にフィン）・させることは必ずしも必要ではないという認識に一部もとづいている。換言すると、ウェーブデフレクタが閉じたときに、デフレクタのエツジが、そのランナの壁部に対して完全にシールされる必要は必ずしもないということである。したがって、本発明は、ウェーブデフレクタをプラスチック材料製として、更に一対のウェーブデフレクタをシャフトと一体に構成し、その結果、これら２つが単一の部品又は部材を形成するようにした。For the purpose of deflecting pressure waves, the present invention provides a wave deflector in the combined launch. It is now recognized that it is not always necessary to precisely fin the flexor. It is based on the department. In other words, when the wave deflector closes, the deflector It is not necessary that the edges of the runners be completely sealed against the walls of their runners. That is to say, yes. Therefore, the present invention provides a wave deflector made of plastic. Furthermore, a pair of wave deflectors are constructed integrally with the shaft. As a result, these two form a single part or member.

本発明の別の特徴は、適切なプラスチック材料により、この一体のウェーブデフレクタが曲げ弾性を有するようにされており、この結果、公知の金属部品より組付けが容易な点である。また、ここに開示したプラスチック製のウェーブデフレクタは、デフレクタとシャフトとの間にスロットを有し、組付は過程中の曲げが容易にされている。Another feature of the invention is that this integral wave differential is made of a suitable plastic material. The rectifier is made to have bending elasticity, and as a result, it can be assembled from known metal parts. It is easy to attach. In addition, the plastic wave deflation disclosed here The deflector has a slot between the deflector and the shaft to prevent bending during assembly. It has been made easier.

更に、本発明によるウェーブデフレクタは、ランチを２つの隣接シリンダに架橋している。デフレクタ端部はシャフトの一部となっており、ランチのそれぞれの壁部内の円形穴にフィツトするようにされている。Furthermore, the wave deflector according to the invention bridges the launch into two adjacent cylinders. are doing. The deflector end is part of the shaft and is attached to each of the launches. It is designed to fit into a circular hole in the wall.

シャフトの中間部分は、この共通の壁部を貫通している。このシャフトの中間部分を適合させやすくするため、共通の壁部にはスロットが設けられている。シャフトの中間部分の軸受けとなるクリップが、このスロットに適合する。このシャフト、クリップ、スロットは、次のように構成され、配置されている。すなわち、ウェーブデフレクタが正確に軸方向に位置せしめられ、２つの隣接ランチ間のスロットが実質的に閉じられる結果、これらのランナの間には、直交流が生じないようにされる。The intermediate portion of the shaft passes through this common wall. The middle part of this shaft Slots are provided in the common wall to facilitate adaptation of the parts. Sha A clip that serves as a bearing for the middle part of the foot fits into this slot. This shade The feet, clips, and slots are constructed and arranged as follows. i.e. , the wave deflector is precisely axially positioned between two adjacent launches. As a result of the slot being essentially closed, there is no cross flow between these runners. be made to look like

本発明の更に別の特徴は、ランナ壁内のデフレクタの軸受部分をシールするため、デフレクタ上に一体のシールリップが形成され、デフレクタを作動させうる偏心体を形成する統合的な設備が設けられ、開閉位置をデフレクタの回転する２つの別個の位置とするのに好都合な捩り止め機構が備えられている点である。更にまた、ウェーブデフレクタを組付ける方法も、本発明の特徴をなしている。Yet another feature of the invention is for sealing the bearing portion of the deflector within the runner wall. , an integral sealing lip is formed on the deflector to provide a deflection that can actuate the deflector. Integrated equipment is provided to form a center body, and the deflector rotates to open and close positions. It is provided with a twist stop mechanism which is convenient for setting it in a separate position. Furthermore Furthermore, the method of assembling the wave deflector is also a feature of the present invention.

有利な実施例の説明第１図は、内燃機関の典型的な吸入システム２０の横断面図である。内燃機関も典型的なものであり、図示の例は４シリンダのガソリン・エンジンである。第１図に示されているのは、エンジンの１つのシリンダのシリンダヘッド２２と、組合された吸入弁機構２４のみである。第１図の横断面図にはシリンダへ通じる吸入口２６の断面が示されている。この吸入口は、吸入弁２４が開かれると、シリンダに対して開放される吸入システム２０を通る空気流路は矢印２８で示しである。吸入システム２０に入る吸気は、まず、操作員の制御の下で絞りブレードの開放度が設定される主絞り弁を通過する。吸気流は、ここから高圧区域３２へ導かれる。この区域３２は、吸入システム２０の縦方向に延びている。システム２０の長さは第１図の図平面に対し直角方向である。各エンジンシリンダに対して、それぞれ２つのランナ３４．３６が付属している。それゆえ、第１図には、１つのシリンダに通じる２つのランナ３４．３６が示されている。これらのランチは吸入口２６へ延び、高圧区域３２を吸入口へ連通させている。電磁式燃料噴射装置３８が、燃料レールブロック４０内に設けられている。噴射装置３８は、適宜に調時されて燃料を吸入口２６内へ噴射して、吸入システムを通過して来た空気と混合され、これにより燃焼可能な混合気が形成され、弁２４が開くと、シリンダ内へこの混合気が導入される。ウェーブデフレクタ４２は、吸入弁機構２４の丁度上流にランナ３６と組合せて配置されている。Description of advantageous embodiments FIG. 1 is a cross-sectional view of a typical intake system 20 for an internal combustion engine. internal combustion engine too Typically, the illustrated example is a four cylinder gasoline engine. 1st Shown in the figure is the cylinder head 22 of one cylinder of the engine and the assembly. Only the suction valve mechanism 24 is combined. The cross section in Figure 1 shows the suction leading to the cylinder. A cross section of the inlet 26 is shown. This suction port is connected to the cylinder when the suction valve 24 is opened. The air flow path through the intake system 20, which is open to the reader, is indicated by arrow 28. Ru. The intake air entering the intake system 20 first passes through the throttle blades under operator control. It passes through the main throttle valve, where the degree of opening is set. Inspiratory air flow is directed from here to high pressure area 32. It will be destroyed. This area 32 extends in the longitudinal direction of the inhalation system 20. system 2 The length 0 is perpendicular to the drawing plane of FIG. for each engine cylinder , each with two runners 34,36. Therefore, in Figure 1, 1 Two runners 34,36 leading to two cylinders are shown. these lunches extends to the inlet 26 and communicates the high pressure area 32 to the inlet. electromagnetic fuel injection A device 38 is provided within the fuel rail block 40. The injector 38 is The fuel is injected into the intake port 26 in a timed manner to eliminate the air passing through the intake system. When the valve 24 is opened, the air is mixed with air, thereby forming a combustible air-fuel mixture. This air-fuel mixture is introduced into the engine. The wave deflector 42 is connected to the suction valve mechanism 24 It is arranged in combination with a runner 36 just upstream of the runner.

第１図は、ウェーブデフレクタ４２が閉じ位置にあるところを示したものである。この状態では、シリンダ５への吸気はランナ３４を通り、ランチ３６は通らない。ウェーブデフレクタは、シリンダ内のピストンが吸入行程を行うときに、シリンダから出る圧力波を阻止又は偏向させる。FIG. 1 shows the wave deflector 42 in the closed position. . In this state, the intake air to the cylinder 5 passes through the runner 34 and does not pass through the lunch 36. stomach. A wave deflector is a wave deflector that is Block or deflect pressure waves exiting the cylinder.

第２図は、２つのウェーブデフレクタ４２を示し、これらのデフレクタは、一つがランナ３４と、他はランナ３６と組合されている。FIG. 2 shows two wave deflectors 42, these deflectors being one are combined with the runner 34, and the others with the runner 36.

第３図、第３Ａ図、第３Ｂ図は、本発明の原理を実現している典型的なウェーブデフレクタ４２である。Figures 3, 3A and 3B illustrate typical waveforms embodying the principles of the invention. This is the deflector 42.

このウェーブデフレクタは、一体のプラスチック部品であり、シャフト４４と一対のウェーブデフレクタ・ブレード４６．４８とを有している。シャフトとデフレクタ・ブレードとは、単一の部品を構成するように一体に形成されている。デフレクタ・ブレード４６゜４８は扁平である。シャフトは、円形の端部分４４ａ、４４ｂと円形の中間部分４Ｃとを有している。中間部分４４ｃには環状の肩５０が形成されている。This wave deflector is an integral plastic part and is integrated with the shaft 44. and a pair of wave deflector blades 46,48. shaft and differential The rector blade is integrally formed to form a single piece. De The flexor blades 46° 48 are flat. The shaft has a circular end portion 44a , 44b and a circular intermediate portion 4C. An annular shoulder 5 is provided in the intermediate portion 44c. 0 is formed.

シャフトは各デフレクタ・ブレードのところでは扁平にしておくことが考えられる。各デフレクタ、ブレードには、平らにされたシャフトのところに並んで４つのスリット５２が設けられている。スリット５２は、シャフトと平行に各デフレクタ・ブレードのエツジから始まりブレードの途中まで延びている。シャフトの両側で、それぞれ２本のスリットが互いに整線せしめられている。これらスリット５２の目的は、ウェーブデフレクタを燃料レールブロック４０に、第３Ａ図及び第３Ｂ図について説明するように仕方で組付けるさいに、シャフトのたわみを容易にすることにある。The shaft could be flattened at each deflector blade. Ru. Each deflector blade has four side by side on the flattened shaft. A slit 52 is provided. A slit 52 is provided in each deflation parallel to the shaft. It begins at the edge of the Kuta blade and extends halfway down the blade. of the shaft On each side, two slits are aligned with each other. These slits The purpose of the bolt 52 is to attach the wave deflector to the fuel rail block 40 as shown in FIG. 3A. When assembling the shaft in the manner described in Figure 3B and It's about making it easier.

デフレクタの材料は、曲げ弾性のある適当なプラスチックである。ウェーブデフレクタの、燃料レールブロックへの組付けは、次のように行われる。まず、ブロック４０に、各ランナの末尾部分をなす適当な構成部材を備えておく。２つのデフレクタ・ブレード４６．４８が、これら部材と一緒に配置される。デフレクタ・ブレード４８は、エンジンの吸入口２６へ通じているランナ３６と組合され、他方のデフレクタ・ブレード４６は吸入口２６と、隣接シリンダのランチ３６と組合される。The material of the deflector is a suitable plastic with bending elasticity. wave differential The rector is assembled to the fuel rail block as follows. First, Bro. The rack 40 is provided with suitable components to form the trailing portion of each runner. two de Flexor blades 46,48 are arranged with these members. deflector - the blades 48 are combined with a runner 36 leading to the engine intake 26; The other deflector blade 46 connects the inlet 26 and the launch 36 of the adjacent cylinder. be combined.

同一軸線上に整線された一対の円形の穴５４．５６が、燃料レールブロック４０内に設けられている。ウェーブデフレクタ４２をブロック４０内に組付ける前に、プラスチック製クリップ５８を肩５０にはめ込む。ブロック４０へのデフレクタ４２の組付けは、シャフト端部４４ｂを、第３Ａ図に示したように穴５６内へ差込むことで行なう。このときに、デフレクタ４２には図示のように、たわみが生じる。次いで、シャフトを矢印６０．６２で示したようにＳ字状にたわませ、シャフト端部４４ａを穴５４に差込み、整列させる。それと同時に、クリップ５８を丁字形スロット６４にはめ込む。このスロット６４は、Ｕ字形スロット６６と直角に形成され、このスロット６６内にはシャフト４４の中央部分４４ｃが位置せしめられる。最終的な組付は位置は第３ＡＢ図に示しである。A pair of circular holes 54 and 56 aligned on the same axis are located in the fuel rail block 40. It is located inside. Before assembling the wave deflector 42 into the block 40 , snap the plastic clip 58 onto the shoulder 50. Deflex to block 40 To assemble the shaft 42, insert the shaft end 44b into the hole 56 as shown in FIG. 3A. This is done by inserting it. At this time, the deflector 42 is deflected as shown in the figure. arise. Next, the shaft is bent in an S-shape as shown by arrows 60 and 62, Insert the shaft end 44a into the hole 54 and align it. At the same time, clip 5 8 into the T-shaped slot 64. This slot 64 is a U-shaped slot 66 The central portion 44c of the shaft 44 is positioned within this slot 66. I am forced to put it there. The final assembly position is shown in Figure 3AB.

クリップ５８の形状は、第５図で最もよ（知ることができる。このクリップは、全体として丁字形をなしており、シャフト４４にフィツトさせるための円形の穴６４を有している。穴６８の直径は、肩５０の間にフィツトする直径である。穴６８は、しかし、部分穴であり、クリップの底部に設けられた狭いカットアウト部７０により穴６８が開かれている。クリップ材料の弾性的な可とう性と結びついて、この狭いカットアウト部のところで、クリップはシャフトにスナップ結合することができる。この様子は、第４図から最もよく知ることができる。第４図には、また、クリップとシャフトがスロット６４を実質的に充たしている様子が示されている。このため、それぞれのデフレクタ・ブレード４６．４８に組合された２つのランチ間の漏れ隙間がブロックされる。第４図に見られるように、クリップのカットアウト部７０には隆起部７１が突入している。スロット６４内に配置されることにより、クリップはカットアウト部が開かなくなり、シャフト４４を密に取囲むことになる。更に、クリップは、軸方向にウェーブデフレクタ４２を穴５４．５６の間に位置させるのに役立っている。また、シャフト端部４４ｂは、シャフト端部４４ａよりい（ふん長くし、組付けが容易になっている。The shape of the clip 58 can be best seen in FIG. It has a T-shape as a whole and has a circular hole for fitting the shaft 44. 64. The diameter of hole 68 is such that it fits between shoulders 50. hole 68, however, is a partial hole, with a narrow cutout provided at the bottom of the clip. A hole 68 is opened by the portion 70 . Combined with the elastic flexibility of the clip material The clip snaps onto the shaft at this narrow cutout. can do. This situation can be best understood from FIG. Figure 4 also shows that the clip and shaft substantially fill the slot 64. It is shown. For this reason, each deflector blade 46, 48 has a The leakage gap between the two launched launches is blocked. As seen in Figure 4, A raised portion 71 protrudes into the cut-out portion 70 of the lip. in slot 64 By positioning the clip, the cutout part will not open and the shaft 4 4 will be closely surrounded. Furthermore, the clip axially connects the wave deflector 4 2 between holes 54 and 56. In addition, the shaft end 44 b is longer than the shaft end 44a, making it easier to assemble.

組付は過程には、一定の、制限された軸方向遊びが必要なので、ウェーブデフレクタは、それぞれのランチ内に完全にフィツトはしない。このことは、しかし、重要なことではない。ランチが実質的に閉じられていれば、圧力波を偏向させる機能は有効に働くからである。シャフトの端部４４ａ、４４ｂは、穴５４．５６に十分にしまりばめされているので、ここからの漏れは問題にならない。The assembly process requires a certain, limited axial play, so wave deflation is Kuta does not fit perfectly within each lunch. This, however, It's not important. If the launch is virtually closed, it will deflect the pressure waves This is because the function works effectively. The ends 44a, 44b of the shaft have holes 54,56 leakage is not a problem as the fit is tight enough.

ウェーブデフレクタはアクチュエータ（図示せず）により操作され、アクチュエータは電子制御ユニット（ＥＣＵ）により制御される。デフレクタ・ブレードは、約９０度離れている開閉位置の間で操作される。The wave deflector is operated by an actuator (not shown) and the actuator The controller is controlled by an electronic control unit (ECU). Deflector blade , operated between open and closed positions approximately 90 degrees apart.

閉じ位置ではデフレクタ・ブレードは、ランナを流れる空気流に対し直角方向に位置し、開位置では平行方向に位置する。第６図、第７図に示したクリップとシャフトの実施例は、この開閉位置を定める捩りとめ機構を有している。このクリップは、シャフトの側部を支えるばね部分７２を有している。シャフトには突起７３が設けてあり、穴６８の内側に２つの凹所７４゜７６が形成されている。これらの凹所７４．７６は９０度離れている。ばね部分７２は、突起７３を凹所７４．７６の間の穴６８の壁部に対して押付ける。デフレクタ・ブレードが空気流をブロックするさいには、突起７３は凹所７４．７６の一つにフィツトし、デフレクタ・ブレードが完全に開いたときには、他方の凹所にフィツトする。このようにして、捩りどめ機構は、デフレクタ・ブレードが、開・閉いずれかの位置に位置決めされ、その中間のどこかの位置に止まらないようにする。In the closed position, the deflector blades are perpendicular to the airflow through the runners. and parallel in the open position. The clip and screen shown in Figures 6 and 7 Embodiments of the shaft include a twist lock mechanism that defines this open and closed position. This chestnut The cap has a spring portion 72 that supports the side of the shaft. protrusion on the shaft 73 and two recesses 74 and 76 are formed inside the hole 68. child These recesses 74,76 are 90 degrees apart. The spring portion 72 moves the protrusion 73 into the recess 7 4. Press against the wall of the hole 68 between 76 and 76. Deflector blades allow airflow When blocking the differential, the protrusion 73 fits into one of the recesses 74, 76 and When the rector blade is fully open, it fits into the other recess. This way In this way, the twist stop mechanism prevents the deflector blade from being in either the open or closed position. Positioned and not stuck somewhere in between.

第８図には、ウェーブデフレクタの操作機構が示しである。この操作機構の場合、端部４４ｂを、穴５６から突出させ、突出した端部にレバー７８を取付けるため、十分に長くしておかねばならない。レバー７８は、シャフトの端部４４ｂの、直径を減じた部分にフィツトする非円形の穴を有し、シャフト端部に形成された肩とスナップ式保持リング８０との間に保持されている。リング８０は直径の減じたシャフト端部にはめ込まれている。FIG. 8 shows the operating mechanism of the wave deflector. For this operating mechanism , the end portion 44b is made to protrude from the hole 56, and the lever 78 is attached to the protruding end portion. It must be kept long enough. The lever 78 is located at the end 44b of the shaft. , with a non-circular hole that fits into the reduced diameter section, formed in the shaft end. between the shoulder and a snap retaining ring 80. Ring 80 has a diameter of Fitted into the reduced shaft end.

第９図に示した連結部は、反対側のシャフト端部４４ａに設けられている。この端部には、１つの穴が設けられており、ビン８２が、燃料レール壁の穴を貫通してシャフト端部の穴内に差込まれている。このビン８２は、壁の穴を貫通して突出するだけの長さを有し、キャップ８４がビン８２の端部にかぶせられている第１０図から第１３図までは、ウェーブデフレクタの別の実施例８６を示したものである。このデフレクタは、第１０図の左側端部にアクチュエータが一体に取付けられている。このアクチュエータは、円筒８８の形状を有し、この円筒はデフレクタの軸と同軸的である。円筒８８には小さな穴９０が設けである。この穴９０はデフレクタ軸から外れた位置にある。ウェーブデフレクタが組付けられる穴は、第１０図で見て右側のシャフト端部と円筒８８とを受容するのに適する形状を有している。燃料レールにデフレクタを組付けたのち、ビン９２を穴９０に差込む。ビン９２は、デフレクタを作動させるアクチュエータに連結することができる。このように、ビンと穴とは偏心位置にあって、レバーを形成している。別の特徴は、円形リップシール９４が円筒８８の外周に備えられていることである。このリップシールは、円筒８８が取付けられている穴の内壁と接触している。The connecting portion shown in FIG. 9 is provided at the opposite shaft end 44a. this A hole is provided at the end so that the bin 82 passes through the hole in the fuel rail wall. is inserted into the hole at the end of the shaft. This bottle 82 protrudes through a hole in the wall. The bottle 82 is long enough to be dispensed, and the cap 84 is placed over the end of the bottle 82. 10 to 13 show another embodiment 86 of the wave deflector. It is. This deflector has an actuator integrally attached to the left end in Figure 10. I'm being kicked. This actuator has the shape of a cylinder 88, which is a differential actuator. It is coaxial with the axis of the rector. The cylinder 88 is provided with a small hole 90. this hole 9 0 is located off the deflector axis. Hole where the wave deflector is assembled is of a shape suitable to receive the shaft end and cylinder 88 on the right side as viewed in FIG. have. After assembling the deflector to the fuel rail, insert the bottle 92 into the hole 90. It's crowded. Bin 92 can be coupled to an actuator that actuates the deflector. Wear. The bottle and hole are thus eccentrically located and form a lever. another is characterized in that a circular lip seal 94 is provided on the outer periphery of the cylinder 88. . This lip seal is in contact with the inner wall of the hole in which the cylinder 88 is attached.

更に別の特徴は、円筒８８の端面が、隣接するデフレクタ・ブレードの側にランナの横断面の直接に接触する部分に相応する断面形状９６を有していることである。ランチ内でのデフレクタ・ブレードの配置は、デフレクタ・ブレードが開かれているときには、円筒８８が空気の連続的な流れを妨げないようになされている。この条件は、第１２図から最もよく知ることができる。シリンダ８８には、デフレクタ・ブレードを製造するのに用いる材料を節約するために、端部に穴を設けである。A further feature is that the end face of the cylinder 88 runs to the side of the adjacent deflector blade. It has a cross-sectional shape 96 corresponding to the directly contacting portion of the cross-section of the Ru.
