Description
【０００１】[0001]
本考案は、例えば内燃機関の補助空気流量を制御する流量制御弁に関する。 The present invention relates to a flow rate control valve for controlling the auxiliary air flow rate of an internal combustion engine, for example.
【０００２】[0002]
周知のように、自動車用ガソリン機関にあっては、機関運転状態に応じてアイ ドリング回転数を制御するために電磁式の流量制御弁が用いられている。かかる 流量制御弁の一般的な構造を図３に示す。 As is well known, in a gasoline engine for automobiles, an electromagnetic flow control valve is used to control the idling speed according to the engine operating condition. The general structure of such a flow control valve is shown in FIG.
【０００３】 すなわち、この流量制御弁は、機関の吸気通路のスロットルバルブをバイパス する補助空気通路１に設けられており、バルブボディ２とソレノイドケーシング ３とを一体的に有している。前記バルブボディ２は、補助空気通路１の１本の吸 入路が接続される補助空気入口部４ａと、該補助空気入口部４ａの両側に設けら れた一対の出口部４ｂ，４ｂとを有し、内部に両端が円環状の金属製バルブシー ト５，６で画成された空気導入室４ｃと、一端がガイド部７を介してガイド筒８ に摺動可能に保持され、かつ他端がアジャスト端壁９の摺動孔９ａに摺動可能に 保持された弁軸１０と、該弁軸１０の略中央両側に夫々固定されて上記バルブシ ート５，６に離着座して空気導入室４ｃを開閉する一対の第１，第２弁体１１， １２とを有している。That is, the flow rate control valve is provided in the auxiliary air passage 1 that bypasses the throttle valve in the intake passage of the engine, and has the valve body 2 and the solenoid casing 3 integrally. The valve body 2 has an auxiliary air inlet portion 4a to which one suction passage of the auxiliary air passage 1 is connected, and a pair of outlet portions 4b and 4b provided on both sides of the auxiliary air inlet portion 4a. And an air introduction chamber 4c having both ends defined by annular metal valve sheets 5 and 6 at one end, and one end slidably held by a guide tube 8 via a guide portion 7 and the other end. Of the valve shaft 10 slidably held in the sliding hole 9a of the adjusting end wall 9 and fixed to both sides of substantially the center of the valve shaft 10 so as to separate from and seat on the valve sheets 5 and 6 and to introduce air. It has a pair of first and second valve bodies 11 and 12 for opening and closing the chamber 4c.
【０００４】 また、この両弁体１１，１２は、合成樹脂材で成形され、アジャスト端壁９側 に装着されたバルブスプリング１３と、前記ソレノイドケーシング３内のプラン ジャスプリングとの相対的なばね力によってバルブシート５，６中央のバルブ孔 ５ａ，６ａを閉塞する位置に弾持されており、この位置では、第１弁体１１の円 錐面１１ａがバルブシート５のシート面５ｂに着座している。The valve bodies 11 and 12 are formed of a synthetic resin material, and are a relative spring between a valve spring 13 mounted on the adjusting end wall 9 side and a plunger spring in the solenoid casing 3. It is elastically held in a position to close the valve holes 5a, 6a in the center of the valve seats 5, 6 by force, and at this position, the conical surface 11a of the first valve body 11 is seated on the seat surface 5b of the valve seat 5. ing.
【０００５】 一方、ソレノイドケーシング３は、内部に電磁コイル及びヨークと、該電磁コ イルの内周に設けられたコアと、該コアに吸引されて摺動するプランジャと、一 端が該プランジャの先端部に連結され、他端が前記弁軸１０と同軸上で連結され た駆動ロッドが収納されている。On the other hand, the solenoid casing 3 is internally provided with an electromagnetic coil and a yoke, a core provided on the inner circumference of the electromagnetic coil, a plunger that is attracted and slid by the core, and one end of the plunger. A drive rod, which is connected to the tip portion and the other end of which is coaxially connected to the valve shaft 10, is housed.
【０００６】 そして、現在の機関運転状態を検出する図外のコントローラから電磁コイルに デューティ制御電流が出力されると、プランジャが駆動ロッド及び弁軸１０を介 して両弁体１１，１２をバルブスプリング１３のばね力に抗して図中右方向へ開 弁させて、２つのバルブ孔５ａ，６ａから空気導入室４ｃに大流量の補助空気を 流入させ、さらに、暖機完了後は、所定の最適な流量を確保するようになってい る。Then, when a duty control current is output to the electromagnetic coil from a controller (not shown) that detects the current engine operating state, the plunger causes the valve elements 11 and 12 to valve through the drive rod and the valve shaft 10. By opening the valve 13 rightward in the figure against the spring force of the spring 13, a large amount of auxiliary air flows into the air introduction chamber 4c from the two valve holes 5a and 6a, and after warming up, a predetermined amount of air is supplied. It is designed to ensure the optimum flow rate.
【０００７】 すなわち、機関の始動初期は、両弁体１１，１２が両バルブ孔５ａ，６ａを大 きく開いて補助空気流量を５０ｌ/min〜８００ｌ/minまで速やかに上昇させて、 暖機促進を行う。一方機関冷却水温が所定以上に上昇し暖機が完了すると、電磁 コイルへの通電量を低下させてコアの吸引力を弱めると、両弁体１１，１２がバ ルブスプリング１３のばね力によって左方向へ移動して両バルブ孔５ａ，６ａを 閉塞する。That is, in the initial stage of starting the engine, both valve bodies 11 and 12 open both valve holes 5a and 6a widely to rapidly increase the auxiliary air flow rate from 50 l / min to 800 l / min to promote warm-up. I do. On the other hand, when the engine cooling water temperature rises above a certain level and warming up is completed, the energizing amount to the electromagnetic coil is reduced and the suction force of the core is weakened, so that both valve elements 11 and 12 are left by the spring force of the valve spring 13. Moving in the direction to close both valve holes 5a, 6a.
【０００８】 ここで、第１弁体１１は、バルブシート５に着座してバルブ孔５ａを完全に閉 塞するが、第２弁体１２は、その外径がバルブシート６バルブ孔６ａよりも若干 小さく設定されて、両者６，１２間にオリフィスが形成されている。したがって 、このオリフィスで暖機完了時の最適な所定の空気流量を確保するようになって いる。Here, the first valve body 11 is seated on the valve seat 5 to completely close the valve hole 5a, but the second valve body 12 has an outer diameter smaller than that of the valve seat 6 valve hole 6a. The orifice is formed between both 6 and 12 by setting it slightly smaller. Therefore, this orifice ensures an optimum predetermined air flow rate at the time of completion of warming up.
【０００９】[0009]
しかしながら、前記従来の流量制御弁にあっては、バルブシート５が金属で形 成されているため、加工精度上、バルブ孔５ａの真円度を十分に得ることが困難 である。このため、閉弁時における第１弁体１１の円錐面１１ａとバルブシート ５のシート面５ｂとの間のシール性能が低下する。したがって、暖機完了後に空 気流量が増加してしまい、アイドリング回転数が上昇する等、回転を不安定にす る要因となる。 However, in the above conventional flow rate control valve, since the valve seat 5 is made of metal, it is difficult to obtain sufficient roundness of the valve hole 5a in terms of processing accuracy. For this reason, the sealing performance between the conical surface 11a of the first valve body 11 and the seat surface 5b of the valve seat 5 at the time of valve closing deteriorates. Therefore, the air flow rate increases after the completion of warm-up, which causes the idling speed to increase, making the rotation unstable.
【００１０】 そこで、バルブスプリング１３のばね力を増加させることも考えられるが、単 にばね力を増加させると、第１弁体１１とバルブシート５との異なる材質上の点 から、第１弁体１１が繰り返し離着座後に円錐面１１ａに摩耗が発生して耐久性 が著しく低下してしまう惧れがある。Therefore, it is conceivable to increase the spring force of the valve spring 13. However, if the spring force is simply increased, the first valve body 11 and the valve seat 5 are made of different materials. There is a fear that the conical surface 11a may be repeatedly worn and seated after the body 11 is repeatedly seated and seated, and the durability may be significantly reduced.
【００１１】 また、電磁コイルへの非通電時にも第１弁体１１がバルブシート５に着座して いる、つまり常閉型になっているため、暖機時に両者５，１１間に付着したオイ ルミストやカーボン等が機関停止後に固着して第１弁体１１がスティックし易く なるという不具合もあった。Further, since the first valve body 11 is seated on the valve seat 5 even when the electromagnetic coil is not energized, that is, it is of the normally closed type, the oil adhered between the both 5 and 11 is warmed up. There is also a problem that the first valve body 11 is apt to stick due to the sticking of the LUMIST, carbon, etc. after the engine is stopped.
【００１２】 本考案は、このような従来の実情に鑑みてなされたものであり、バルブシート と弁体との摩耗、及び両者間のカーボン等によるスティックの発生が防止された 流量制御弁の提供を目的とする。The present invention has been made in view of the above conventional circumstances, and provides a flow rate control valve in which abrasion between a valve seat and a valve body and sticking due to carbon or the like between them are prevented. With the goal.
【００１３】[0013]
前記課題を解決するために本考案にあっては、流通路の途中に配置されたバル ブボディの内部に設けられたバルブシートと、該バルブシートに離着座してバル ブ孔を開閉する弁体とを備えた流量制御弁において、前記バルブシートの内周部 あるいは弁体の外周部のいずれか一方を低粘着剤を配合したゴム部材で形成した 。 In order to solve the above problems, according to the present invention, a valve seat provided inside a valve body disposed in the middle of a flow passage, and a valve body that is seated on and off the valve seat to open and close a valve hole. In the flow control valve having the above, either the inner peripheral portion of the valve seat or the outer peripheral portion of the valve body is formed of a rubber member mixed with a low-adhesive agent.
【００１４】 また、前記バルブシートの外周部内周面あるいは弁体の内周部外周面に係止部 を設ける一方、前記ゴム部材に、前記係止部に径方向から係合する係合部を設け た。Further, while the engaging portion is provided on the inner peripheral surface of the outer peripheral portion of the valve seat or the outer peripheral surface of the inner peripheral portion of the valve body, the rubber member is provided with an engaging portion that engages with the engaging portion in the radial direction. I set it up.
【００１５】[0015]
前記構成においては、バルブ孔を形成するバルブシートの内周部がゴム部材で 形成されているため、弁体との十分な密着性が確保されて、シール性能が向上す る。また、ゴム部材に低粘着剤が配合されているため、カーボン等が付着しても バルブシートと弁体との固着力が低減し、長時間に亘って両者が接触していても 、スティックすることなく容易に離間させることができる。 In the above structure, since the inner peripheral portion of the valve seat forming the valve hole is formed of a rubber member, sufficient adhesion with the valve body is ensured and the sealing performance is improved. Also, since the rubber member contains a low-adhesive agent, the adhesion force between the valve seat and the valve body is reduced even if carbon etc. adheres, and even if both are in contact for a long time, they will stick. Can easily be separated.
【００１６】 また、前記バルブシートの外周部内周面あるいは弁体の内周部外周面に係止部 を設ける一方、前記ゴム部材に、前記係止部に径方向から係合する係合部を設け れば、係止部と係合部との径方向からの係合により、例えばバルブシートの外周 部とゴム部材との結合性が向上し、ゴム部材の軸方向からの不用意な離脱が防止 される。Further, while the engaging portion is provided on the inner peripheral surface of the outer peripheral portion of the valve seat or the outer peripheral surface of the inner peripheral portion of the valve body, the rubber member is provided with an engaging portion that engages with the engaging portion in the radial direction. If provided, the engagement between the locking portion and the engaging portion in the radial direction improves the bondability between, for example, the outer peripheral portion of the valve seat and the rubber member, and prevents the rubber member from being accidentally disengaged from the axial direction. To be prevented.
【００１７】[0017]
以下、本考案の一実施例を図にしたがって説明する。なお、従来と共通の構成 個所には同一の符号を付して説明を省略する。 An embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same components as those of the related art are designated by the same reference numerals and the description thereof will be omitted.
【００１８】 すなわち、本考案の流量制御弁は、従来と同様に自動車用ガソリン機関の補助 空気量制御用に用いられており、図２の２はバルブボディ、３はソレノイドケー シング、４ａは補助空気入口部、４ｂ，４ｂは出口部、４ｃは空気導入室、１０ は弁軸、１１，１２は弁軸１０に設けられた合成樹脂材からなる一対の第１，第 ２弁体、１３はアジャスト端壁９に一端が弾持されて図外のプランジャスプリン グのばね力との相対圧で両弁体１１，１２を弾持するバルブスプリングである。 そして、図中２１は第１弁体１１が離着座して中央のバルブ孔２１ａが開閉制 御される円環状の第１バルブシート、６は第２弁体１２がバルブ孔６ａ内を摺動 して開口面積が可変制御される第２円環状のバルブシートであり、この第２バル ブシート６は、バルブボディ２に一体に形成されている。That is, the flow control valve of the present invention is used for controlling the auxiliary air amount of a gasoline engine for automobiles as in the conventional case. In FIG. 2, 2 is a valve body, 3 is a solenoid casing, and 4a is an auxiliary. Air inlet parts, 4b, 4b are outlet parts, 4c is an air introduction chamber, 10 is a valve shaft, 11 and 12 are a pair of first and second valve bodies made of a synthetic resin material provided on the valve shaft 10, and 13 is The valve spring has one end elastically supported by the adjusting end wall 9 and elastically supports both valve bodies 11 and 12 by a relative pressure with a spring force of a plunger spring (not shown). Further, in the figure, reference numeral 21 denotes an annular first valve seat in which the first valve body 11 is seated on and off and the central valve hole 21a is controlled to open and close, and 6 the second valve body 12 slides in the valve hole 6a. Thus, the second valve seat 6 is a second annular valve seat whose opening area is variably controlled. The second valve seat 6 is formed integrally with the valve body 2.
【００１９】 一方第１バルブシート２１は、バルブボディ２の内周面に形成された嵌合溝２ ａに嵌合固定された金属製の環状外周部２２と、該外周部２２の内周に焼き付け 固定された環状のゴム部材たるシート部２３とから構成されている。前記外周部 ２２は、図１に示すように内周面の第２バルブシート６側の端縁に軸心方向へ突 出した係止部たる突起部２４が一体に設けられている。この突起部２４は、断面 略クランク状に折曲形成されて、先端部位２４ａが断面略矩形状に形成されてい る。On the other hand, the first valve seat 21 includes a metal annular outer peripheral portion 22 fitted and fixed in a fitting groove 2 a formed on the inner peripheral surface of the valve body 2, and an inner peripheral surface of the outer peripheral portion 22. It is composed of a sheet portion 23 which is an annular rubber member fixed by baking. As shown in FIG. 1, the outer peripheral portion 22 is integrally provided with a protruding portion 24, which is a locking portion protruding in the axial direction, at an end edge of the inner peripheral surface on the second valve seat 6 side. The projecting portion 24 is bent to have a substantially crank shape in cross section, and the tip portion 24a is formed to have a substantially rectangular cross section.
【００２０】 一方、シート部２３は、低粘着剤を配合したフッ素ゴムからなり、図１に示す ように一端側に第１弁体１１が離着座する円環状のシート面２３ａが形成されて いると共に、内部周方向に前記突起部２４に径方向から嵌合する係合部たる係合 溝２５が形成されている。この係合溝２５は、前記突起部２４の外形状に沿った 断面略クランク状に折曲形成されていると共に、中央部２５ａが先端部位２４ａ と同一の断面略矩形状に形成されている。なお、ソレノイドケーシング３内には 、従来と同様に電磁コイル，ヨーク，プランジャ，駆動ロッドが収納されている 。On the other hand, the seat portion 23 is made of fluororubber mixed with a low-adhesive agent, and has an annular seat surface 23a on one end side on which the first valve body 11 is seated, as shown in FIG. At the same time, an engaging groove 25 is formed in the inner circumferential direction, which is an engaging portion that fits in the projection 24 in the radial direction. The engaging groove 25 is formed by bending a substantially crank-shaped section along the outer shape of the protrusion 24, and has a central section 25a having a substantially rectangular section similar to the tip portion 24a. In the solenoid casing 3, an electromagnetic coil, a yoke, a plunger and a drive rod are housed as in the conventional case.
【００２１】 したがって、この実施例によれば、第１バルブシート２１のシート部２３がフ ッ素ゴム材で形成されているため、暖機完了後等において、第１弁体１１の円錐 面１１ａが弾性シート面２３ａに密着して十分な気密性を確保する。このため、 第１弁体１１とバルブシート２１間のシール性能が向上し、空気の漏れを確実に 防止することができる。この結果、アイドリング回転数の過上昇や不安定化を防 止することが可能になる。 また、バルブシート２１と第１弁体１１との衝突が 緩和されるため、摩耗の発生も防止でき、耐久性の向上が図れる。Therefore, according to this embodiment, since the seat portion 23 of the first valve seat 21 is made of the fluororubber material, the conical surface 11a of the first valve body 11 is formed after the completion of warming up. Adheres to the elastic sheet surface 23a to ensure sufficient airtightness. Therefore, the sealing performance between the first valve body 11 and the valve seat 21 is improved, and air leakage can be reliably prevented. As a result, it becomes possible to prevent an excessive increase in idling speed and instability. Further, since the collision between the valve seat 21 and the first valve body 11 is alleviated, the occurrence of wear can be prevented and the durability can be improved.
【００２２】 さらに、シート部２３には低粘着剤も配合されているため、フッ素ゴム材と相 俟って第１弁体１１との離れ性が向上し、機関停止後におけるカーボン等による シート部２３と第１弁体１１とのスティックが十分に防止できる。Further, since the seat portion 23 also contains a low-adhesive agent, the separability from the first valve body 11 is improved in combination with the fluororubber material, and the seat portion is made of carbon or the like after the engine is stopped. It is possible to sufficiently prevent the stick between the second valve body 23 and the second valve body 11.
【００２３】 しかも、シート部２３が外周部２２の突起部２４に係合溝２５を介して径方向 から嵌合固定されているため、結合力が強化され、たとえ第１弁体１１に接着し て軸方向の力が作用しても、該シート部２３の外周部２２からの不用意な抜け出 しが確実に防止され、長期に亘り安定かつ確実な作動が得られる。Moreover, since the seat portion 23 is fitted and fixed in the projection portion 24 of the outer peripheral portion 22 in the radial direction via the engaging groove 25, the coupling force is strengthened and even if it is adhered to the first valve body 11. Even if a force in the axial direction is applied, the seat portion 23 is reliably prevented from accidentally coming out of the outer peripheral portion 22, and stable and reliable operation can be obtained for a long period of time.
【００２４】 なお、本考案においては、本実施例と逆に第１弁体１１を低粘着剤を配合した フッ素ゴム材で形成することも可能であり、また、突起部２４をシート部２３側 に、係合溝２５を外周部２２側に形成することも可能である。In the present invention, contrary to the present embodiment, the first valve body 11 can be formed of a fluororubber material mixed with a low-adhesive agent, and the protrusion 24 is located on the side of the seat portion 23. Further, it is possible to form the engagement groove 25 on the outer peripheral portion 22 side.
【００２５】[0025]
以上の説明で明らかなように、着座時におけるバルブシートと弁体との間のシ ール性能が一段と向上し、流量を高精度に制御することが可能になる。また、バ ルブシートと弁体との衝突力が緩和されるため、両者間の摩耗が防止され、耐久 性が向上する。しかも、バルブシートと弁体との固着力が低減して離れ性が向上 し、カーボン等によるスティックの発生が防止される。 As is clear from the above description, the sealing performance between the valve seat and the valve body when seated is further improved, and the flow rate can be controlled with high accuracy. Further, since the collision force between the valve seat and the valve body is alleviated, the wear between the two is prevented and the durability is improved. Moreover, the sticking force between the valve seat and the valve body is reduced to improve the separating property, and the sticking due to carbon or the like is prevented.
【００２６】 また、バルブシートの外周部内周面あるいは弁体の内周部外周面に係止部を設 ける一方、ゴム部材に、係止部に径方向から係合する係合部を設ければ、バルブ シートの外周部とシート部との結合力が強化されて、シート部の軸方向への不用 意な抜け出しが防止され、長期に亘り安定かつ確実な作動を得ることができる。Further, while the engaging portion is provided on the inner peripheral surface of the outer peripheral portion of the valve seat or the outer peripheral surface of the inner peripheral portion of the valve body, the rubber member is provided with an engaging portion that engages with the engaging portion in the radial direction. For example, the coupling force between the outer peripheral portion of the valve seat and the seat portion is strengthened to prevent the seat portion from being accidentally pulled out in the axial direction, so that stable and reliable operation can be obtained for a long period of time.
