Description

本発明は、たとえば燃料電池駆動装置を有する車両で適用するための、気体状の媒体を、特に水素を制御するための調量弁に関する。 The present invention relates to a metering valve for controlling a gaseous medium, especially hydrogen, for application, for example, in a vehicle having a fuel cell drive.

特許文献１は、気体状の媒体を、特に水素を制御するための比例弁として構成された調量弁を記載しており、この比例弁は、ノズル本体と、閉止部材と、弾性的なシール部材とを含んでいる。ノズル本体には、閉止部材によって弁座で解放または閉止することができる少なくとも１つの通過開口部が構成されている。弾性的なシール部材は弁座で封止をする。 Patent Document 1 describes a metering valve configured as a proportional valve for controlling a gaseous medium, particularly hydrogen, and the proportional valve has a nozzle body, a closing member, and an elastic seal. Includes members. The nozzle body is configured with at least one passage opening that can be opened or closed at the valve seat by a closing member. The elastic sealing member is sealed with a valve seat.

特に燃料電池システムのアノード領域の比例弁として適用するときの比例弁の通常の動作では、頻繁な開放プロセスと閉止プロセスが生じる。燃料電池のアノード経路での洗浄プロセスを最適化するために、または燃料電池構造での吸引ジェットポンプの最善の動作のために、追加の切換プロセスも望まれる場合があり得る。しかし比例弁の頻繁な開放と閉止は弁座での摩耗や、弁座に対する閉止部材の傾動をもたらす。閉止部材と弁座の間で角度許容差が発生し得るからである。このことは、ひいては比例弁全体の密閉性に対してマイナスの影響を及ぼす。 The normal operation of a proportional valve, especially when applied as a proportional valve in the anode region of a fuel cell system, results in frequent opening and closing processes. Additional switching processes may also be desired to optimize the cleaning process at the fuel cell anode path, or for the best operation of the suction jet pump in the fuel cell structure. However, frequent opening and closing of the proportional valve results in wear on the valve seat and tilting of the closing member with respect to the valve seat. This is because an angle tolerance can occur between the closing member and the valve seat. This, in turn, has a negative effect on the tightness of the entire proportional valve.

それに対して、気体状の媒体を、特に水素を制御するための本発明による調量弁は、調量弁の頻繁な開放プロセスと閉止プロセスにもかかわらず、弁座での密閉性が保証されるという利点を有する。 In contrast, the metering valve according to the invention for controlling gaseous media, especially hydrogen, is guaranteed to be hermetically sealed at the valve seat despite the frequent opening and closing processes of the metering valve. Has the advantage of

そのために、気体状の媒体を、特に水素を制御するための調量弁は、流入領域から通過開口部への開口部断面を開放および閉止するために弁座と協同作用する長手方向に可動の平坦な閉止部材が中に配置されたバルブハウジングを有する。弁座は、バルブハウジングに収容されてこれと固定的に結合されたノズルの、閉止部材のほうを向いている着座面にある周回するシールエッジとして構成される。これに加えてノズルの着座面はテーパ状に構成されており、閉止部材は調量弁が閉じた位置にあるときに周回するシールエッジに接して径方向の突出部を有する。径方向の突出部は、閉止部材が最大に形成された傾斜姿勢にあるときノズルの着座面の上で閉止部材の最大の傾斜位置を制限し、テーパ状の着座面の開口角βは１７２°から１７８°の間の値範囲にある。 To that end, the metering valve for controlling gaseous media, especially hydrogen, is longitudinally movable in cooperation with the valve seat to open and close the opening cross section from the inflow region to the passage opening. It has a valve housing with a flat closure member placed inside. The valve seat is configured as an orbiting seal edge on the seating surface of the nozzle housed in the valve housing and fixedly coupled to it facing towards the closure member. In addition to this, the seating surface of the nozzle is configured to be tapered, and the closing member has a radial protrusion in contact with the seal edge that orbits when the metering valve is in the closed position. The radial protrusion limits the maximum tilt position of the closure member on the nozzle seating surface when the closure is in the maximally formed tilted position, with the tapered seating surface opening angle β of 172 °. It is in the value range between 178 ° and.

本発明に基づく調量弁により、下降していく着座面によって、弁座と閉止部材の間の角度誤差にもかかわらず均等な力分布が閉止部材で生成され、このことは、ひいてはいっそう高い密閉性につながる。 With the metering valve according to the present invention, the descending seating surface produces an even force distribution in the closing member despite the angular error between the valve seat and the closing member, which in turn results in a higher sealing. It leads to sex.

第１の好ましい発展例では、径方向の突出部は周回するシールエッジの中央から閉止部材の外側の周回エッジまで延び、０．２ｍｍから２ｍｍの、好ましくは０．５ｍｍから１ｍｍの幅Ｘを有することが意図される。ノズルの周回するシールエッジは０．０４ｍｍから０．２ｍｍの間の、好ましくは０．１ｍｍの高さＲを有するのが好ましい。このようにしてシールエッジが、弁座と閉止部材の間に配置された弾性的なシール部材の中へ低い力で入り込むことができるという利点があり、それにより、閉止部材と、ノズルの着座面への径方向の突出部の載置面とに追加的な傾き位置が生じたときに、弁座での高い密閉性およびそれによる調量弁の最善の機能形態が保証される。 In a first preferred development example, the radial overhang extends from the center of the orbiting seal edge to the outer orbiting edge of the closure member and has a width X of 0.2 mm to 2 mm, preferably 0.5 mm to 1 mm. Is intended. The orbiting seal edge of the nozzle preferably has a height R of between 0.04 mm and 0.2 mm, preferably 0.1 mm. In this way, the seal edge has the advantage of being able to enter the elastic sealing member arranged between the valve seat and the closing member with a low force, whereby the closing member and the seating surface of the nozzle are seated. High airtightness at the valve seat and thereby the best functional form of the metering valve is guaranteed when an additional tilt position occurs with the mounting surface of the radial protrusion to.

本発明の別の実施形態では、閉止部材が電磁石によって、および閉止部材と作用接続された磁気アーマチュアによって長手方向に可動であることが意図されるのが好ましい。このようにして、気体状の媒体を調量弁によって制御可能である。 In another embodiment of the invention, it is preferred that the closure member is intended to be longitudinally movable by an electromagnet and by a magnetic armature acting and connected to the closure member. In this way, the gaseous medium can be controlled by the metering valve.

好ましい発展例では、調量弁の長軸に対して径方向に流入通路がバルブハウジングに構成され、該流入通路によって調量弁の流入領域を気体状の媒体で充填可能であることが意図される。 In a preferred development, it is intended that an inflow passage is configured in the valve housing radially with respect to the major axis of the metering valve, which allows the inflow region of the metering valve to be filled with a gaseous medium. NS.

記載されている調量弁は比例弁として構成されるのが好ましく、特に燃料電池構造で燃料電池のアノード領域への水素供給を制御するのに適している。その利点は、アノード経路での少ない圧力変動と静粛な動作である。 The metering valve described is preferably configured as a proportional valve and is particularly suitable for controlling the hydrogen supply to the anode region of the fuel cell in a fuel cell structure. Its advantages are low pressure fluctuations and quiet operation in the anode path.

図面には、燃料電池への特に水素のガス供給を制御するための本発明による調量弁の実施例が示されている。図面は次のものを示す。 The drawings show examples of a metering valve according to the invention for controlling the gas supply of hydrogen, in particular to the fuel cell. The drawings show the following:

図１は、本発明による調量弁１００の実施例を縦断面図で示している。この調量弁１００は、内部空間２６が中に構成されたバルブハウジング１２を有している。内部空間２６の中に、磁気コイル１３と内極１０と外極１１とを含む電磁石１３０が配置されている。内極１０は、非磁性材料からなるスペーサブッシュ部材１４を介してバルブハウジング１２と結合されている。 FIG. 1 is a vertical sectional view showing an embodiment of the metering valve 100 according to the present invention. The metering valve 100 has a valve housing 12 having an internal space 26 inside. An electromagnet 130 including a magnetic coil 13, an inner pole 10 and an outer pole 11 is arranged in the internal space 26. The inner pole 10 is coupled to the valve housing 12 via a spacer bush member 14 made of a non-magnetic material.

さらに、内部空間１２で取り囲まれるアーマチュア空間９の中に、ピン状の部材５を有するストローク運動可能な磁気アーマチュア６が配置されており、ピン状の部材５は磁気アーマチュア６と固定的に結合されるとともに、内極１０の切欠き２７にもバルブハウジング１２の切欠き２８にも収容、案内されている。磁気アーマチュア６はプランジャ型アーマチュアとして構成され、ストローク運動をするときに内極１０の切欠き２２に収容される。 Further, in the armature space 9 surrounded by the internal space 12, a stroke-movable magnetic armature 6 having a pin-shaped member 5 is arranged, and the pin-shaped member 5 is fixedly coupled to the magnetic armature 6. At the same time, it is accommodated and guided in the notch 27 of the inner pole 10 and the notch 28 of the valve housing 12. The magnetic armature 6 is configured as a plunger-type armature and is housed in the notch 22 of the inner pole 10 during stroke motion.

バルブハウジング１２と内極１０がばね空間８を区切っており、該ばね空間の中に、磁気アーマチュア６のピン状の部材５の皿状の端部１６が突入している。ピン状の部材５の皿状の端部１６に閉止ばね１５が支持されていて、該閉止ばねにより磁気アーマチュア６がピン状の部材５とともに初期応力をかけられる。閉止ばね１５と反対を向くほうのピン状の部材５の端部は、平坦な閉止部材２と固定的に結合されている。閉止部材２はピン状の端部５と反対を向くほうの端部に弾性的なシール部材３を有しており、調量弁１００の流入領域７に配置されている。ばね空間８とアーマチュア空間９は第１の接続通路２４を介して、およびアーマチュア空間９と流入領域７は第２の接続通路２５を介して、それぞれ互いに流体接続されている。 The valve housing 12 and the inner pole 10 separate the spring space 8, and the dish-shaped end 16 of the pin-shaped member 5 of the magnetic armature 6 is inserted into the spring space 8. A closing spring 15 is supported by the dish-shaped end 16 of the pin-shaped member 5, and the magnetic armature 6 is subjected to initial stress together with the pin-shaped member 5 by the closing spring. The end of the pin-shaped member 5 facing away from the closing spring 15 is fixedly coupled to the flat closing member 2. The closing member 2 has an elastic sealing member 3 at an end opposite to the pin-shaped end 5, and is arranged in the inflow region 7 of the metering valve 100. The spring space 8 and the armature space 9 are fluidly connected to each other via the first connecting passage 24, and the armature space 9 and the inflow region 7 are fluidly connected to each other via the second connecting passage 25.

調量弁１００の長軸１８に対して径方向に流入通路３１が構成されていて、該流入通路によって調量弁１００の流入領域７を気体状の媒体で充填可能である。流入領域７はバルブハウジング１２のほかにノズル１によっても区切られており、該ノズルに通過開口部２１が構成されている。弾性的なシール部材３のほうを向く、調量弁１００の長軸１８に対して径方向にテーパ状であるノズル１の着座面１ａに周回するシールエッジ２０が構成されていて、これに弁座４が構成されている。周回するシールエッジ２０は、軸方向に０．０４ｍｍから０．２ｍｍの間の、好ましくは０．１ｍｍの高さＲを有している。調量弁１００が閉じた位置にあるとき、弾性的なシール材３が閉止ばね１５の力付勢によって弁座４に当接し、それにより流入領域７と通過開口部２１の間の接続が閉じられる。 An inflow passage 31 is configured in the radial direction with respect to the major axis 18 of the metering valve 100, and the inflow region 7 of the metering valve 100 can be filled with a gaseous medium by the inflow passage. The inflow region 7 is divided by a nozzle 1 in addition to the valve housing 12, and the nozzle has a passage opening 21. A seal edge 20 that faces the elastic sealing member 3 and circulates around the seating surface 1a of the nozzle 1 that is radially tapered with respect to the major axis 18 of the metering valve 100 is configured. The seat 4 is configured. The orbiting seal edge 20 has a height R of between 0.04 mm and 0.2 mm, preferably 0.1 mm, in the axial direction. When the metering valve 100 is in the closed position, the elastic sealing material 3 abuts on the valve seat 4 by the force of the closing spring 15, thereby closing the connection between the inflow region 7 and the passage opening 21. Be done.

調量弁の機能形態 Functional form of metering valve

調量弁１００はここでは比例弁として構成されている。磁気コイル１３が通電されていないとき、閉止ばね１５を通じて閉止部材２が弁座４に押圧され、それにより、流入領域７と通過開口部２１の間の接続が遮断されて、ガス貫流が行われない。 The metering valve 100 is configured here as a proportional valve. When the magnetic coil 13 is not energized, the closing member 2 is pressed against the valve seat 4 through the closing spring 15, thereby breaking the connection between the inflow region 7 and the passage opening 21 to allow gas flow through. No.

磁気コイル１３が通電されると、閉止ばね１５の閉止力と反対方向を向く磁力が磁気アーマチュア６に対して生成される。この磁力がピン状の部材５を介して閉止部材２に伝達され、それにより閉止ばね１５の閉止力が過剰補償されて、閉止部材２が弁座４から持ち上げられる。流入領域７から通過開口部２１の方向へのガス貫流がリリースされる。 When the magnetic coil 13 is energized, a magnetic force directed in the direction opposite to the closing force of the closing spring 15 is generated with respect to the magnetic armature 6. This magnetic force is transmitted to the closing member 2 via the pin-shaped member 5, whereby the closing force of the closing spring 15 is excessively compensated, and the closing member 2 is lifted from the valve seat 4. A gas flow from the inflow region 7 toward the passage opening 21 is released.

閉止部材２のストロークは、磁気コイル１３での電流強さの高さを通じて調整することができる。磁気コイル１３での電流強さが高くなるほど、閉止部材２のストロークが大きくなるとともに、調量弁１００でのガス貫流も多くなる。閉止ばね１５の力はストローク依存的だからである。磁気コイル１３での電流強さが低下すると閉止部材２のストロークも減少し、そのようにしてガス貫流が絞られる。 The stroke of the closing member 2 can be adjusted through the height of the current strength in the magnetic coil 13. The higher the current strength in the magnetic coil 13, the larger the stroke of the closing member 2 and the larger the gas flow through the metering valve 100. This is because the force of the closing spring 15 is stroke-dependent. When the current strength in the magnetic coil 13 decreases, the stroke of the closing member 2 also decreases, and thus the gas flow through is narrowed.

磁気コイル１３での電流が遮断されると磁気アーマチュア６に対する磁力が低下し、それにより、ピン状の部材５による閉止部材２に対する力が低下する。閉止部材２が通過開口部２１の方向に動いて、弾性的なシール部材３をもって弁座４で封止をする。調量弁１００でのガス貫流が遮断される。 When the current in the magnetic coil 13 is cut off, the magnetic force on the magnetic armature 6 decreases, whereby the force on the closing member 2 by the pin-shaped member 5 decreases. The closing member 2 moves in the direction of the passing opening 21 and seals with the valve seat 4 with the elastic sealing member 3. The gas flow through the metering valve 100 is cut off.

図２は、図１の本発明による調量弁の弁座４の領域の拡大部分図を縦断面で示している。調量弁１００が閉じた位置にあるとき、弾性的なシール部材３が弁座４の上に当接して、周回するシールエッジ２０が弾性的なシール部材３の中に入り込む。ノズル１のテーパ状の着座面１ａにより、閉止部材２は弾性的なシール部材３をもって、周回するシールエッジ２０の中央から閉止部材１０の外側の周回エッジ１７まで延びる、０．２ｍｍから２ｍｍの、好ましくは０．５ｍｍから１ｍｍの幅Ｘを有する径方向の突出部１０を有している。 FIG. 2 shows an enlarged partial view of a region of the valve seat 4 of the metering valve according to the present invention of FIG. 1 in a vertical cross section. When the metering valve 100 is in the closed position, the elastic seal member 3 abuts on the valve seat 4, and the orbiting seal edge 20 enters the elastic seal member 3. Due to the tapered seating surface 1a of the nozzle 1, the closing member 2 has an elastic sealing member 3 extending from the center of the orbiting seal edge 20 to the outer peripheral edge 17 of the closing member 10 from 0.2 mm to 2 mm. It preferably has a radial protrusion 10 having a width X of 0.5 mm to 1 mm.

弁座４と弾性的なシール部材３との間の角度許容差は、弾性的なシール部材３を含めた閉止部材２全体の傾きにつながる。このことが図３に示されている。ここで最大に形成された閉止部材１０の傾斜姿勢が示されている。そのときに径方向の突出部１９が、閉止部材２の最大の傾斜位置をノズル１の着座面１ａの上で制限する。テーパ状の着座面１ａの開口角βは、１７２°から１７８°の間の値範囲にある。最大に形成された閉止部材２の傾斜姿勢のとき、径方向の突出部１９は着座面１ａとの接触線３０をもって１８０°−βに相当する角度αを形成する。この角度αは２°から８°の間の値範囲にある。このようにして閉止部材２の傾動にもかかわらず、最大に形成された閉止部材２の傾斜姿勢のときであっても、弁座４での密閉性を実現することができる。 The angle tolerance between the valve seat 4 and the elastic sealing member 3 leads to the tilt of the entire closing member 2 including the elastic sealing member 3. This is shown in FIG. Here, the tilted posture of the closing member 10 formed to the maximum is shown. At that time, the radial protrusion 19 limits the maximum tilted position of the closing member 2 on the seating surface 1a of the nozzle 1. The opening angle β of the tapered seating surface 1a is in the value range between 172 ° and 178 °. When the closing member 2 is tilted to the maximum, the radial protrusion 19 forms an angle α corresponding to 180 ° −β with the contact line 30 with the seating surface 1a. This angle α is in the range of values between 2 ° and 8 °. In spite of the tilting of the closing member 2 in this way, the airtightness of the valve seat 4 can be realized even in the tilted posture of the closing member 2 formed to the maximum.
