【発明の詳細な説明】 噴射装置 この発明は、噴射ノズルホルダを備え、その圧力チャネルは一方で噴射ポンプ に接続し他方で噴射ノズルと接続し、ノズルホルダはノズルピンを縦方向に移動 可能に収容するノズル体に対して中間盤を介して気密に支持されるディーゼルエ ンジン用噴射装置に関する。ここで、変形可能な金属製空洞シリンダ状パッキン グの一端が密封面に対して支持され、ノズル体をノズルホルダと結合するノズル 固定ネジを引き戻すにしたがってその台座に対して変形する。 この種の噴射装置においては、ノズルホルダとノズル体との間の伝達領域内に ある圧力チャネルを密封する必要があり、これによって燃料がノズル締結ナット のネジ山を介してバネ室内に漏れるのを確実に防止することができる。このこと を達成するため、既知の実施形態においては、互いに対向するノズルホルダとノ ズル体の前面ならびにノズル体とノズルホルダの間に配置される中間盤の両前面 部が精密加工された表面を備えており、これは高コストな加工処理によって、成 形、平面処理ならびに研磨されるものである。ノズルホルダ内の圧力チャネルは 、中間盤内の適宜な孔に接合しており、さらにこの孔はノズルに通ずる圧力チャ ネルに接合している。精密に平行研磨された中間盤の両前面ならびにこれに接す るノズルホルダならびにノズル体の前面部の表面により、確実な密封が達成され 、ここで、もちろん高コストな表面処理が必要とされる。この種の噴射装置は、 日本国特許第PS 6−66222号に記載されている。 したがって、本発明の目的は、一方で圧力チャネル、他方でノズル体ならびに ノズルホルダの内部の密封を達成し、ノズル締結ナットのネジ山を通ずる燃料の 漏洩を防止し、さらにこれを低コストに達成することである。 この課題は、請求項1に記載された本発明の特徴にしたがって解決される。残 面が対向配置された中間盤上部より適宜持ち上げられており、これは残面が上部 に対して小さな角度をもって接合するからであるが、密封体はノズルホルダ内の 圧力チャネルを中間盤あるいはノズル体と気密に接合させ、ここで錐形状の密封 面によって密封体の自律的な中心化が達成され、またこれが高圧条件においても 気密に密封することが保持される。この方式によって1000バールまでの最大 圧力を制御することができる。加えて、高 密度な密封端により、針状ロックスプリングフレームの追加的な密封処置が実施 される。 好適な一実施例において、密封体はノズルホルダに整合する円錐形状の外形か らなる錐形状の台座を備える錐形密封部材として形成され、この錐形密封部材が 支持されている対向密封面が中間盤の上面によって形成される。 この錐形密封部材により、対向するノズルホルダの前面を精密加工することな く、圧力チャネルを高圧側の中間盤に気密に接合するという部分課題が解決され る。 ここで、錐形密封部材をこれを収容する台座に比して軸方向に短く形成するこ とにより、錐形密封部材の柔軟性が推進される。 第二の実施例においては、密封体を外側で対向する2つの錐形部分からなる密 封リングとして形成し、ここで一つの部分はノズルホルダ内の錐形台座に整合し 、他方の部分は中間盤の圧力チャネル孔部の錐形に広がった開口部に整合するよ う形成し、中間盤の圧力チャネル孔部の開口部によって対向密封面を形成する。 この種の二つの錐形部分からなる密封リングによって得られる密封作用は、特に 有効で持続的なものとなる。このことは、請求項5に記載されている第三の実施 形態にも該当し、これにおいては、中間盤の支持孔部を貫通する密封管部材によ って中間盤を適宜に架橋し、すなわち、ここで高圧側の密封は、一方でノズルホ ルダ内、他方でノズル体内において、互いに対向する圧力チャネルの開口部間で 直接実施される。 次に、本発明の実施例につき添付図面を参照しながら説明する。ここで: 図1は、ノズル締結ナットを完全に締める前のノズルホルダ/ノズル体の断面 図、 図2は、図1の圧力チャネル領域の拡大断面図、 図3は、ノズル締結ナットを完全に締めた後の図1の断面図、 図4および図5は、それぞれ図2の変更例を示す説明図である。 請求項1ないし3に記載されている噴射装置は、圧力チャネル2を有するノズ ルホルダ1を備え、この圧力チャネル内において燃料が図示されていない噴射ポ ンプから矢印P1の方向に通流し、さらにノズル体3を備え、これは以下により 詳細に説明する高圧結合を介してノズルホルダ1の圧力チャネル2に接続してい る。ノズル体3の中心孔部内にはノズル針部材5が配設されており、その内側の 針端部6は球形状に形成されている。ノズル針部材5の針端部6は、ノズルホル ダ1の中央孔部7内に配置された圧力バネ8によってノズル方向に支持されてい る。このバネは、ノズル針部材5の針端部6上 に配設された圧力ボルト9に対して作用することによって、針端部6に対する閉 鎖方向の圧力をもたらす。 ノズル体3およびノズルホルダ1は、ノズル締結ナット10によって互いに接 続され、これは内側ネジ山11によってノズルホルダ1の外側ネジ山にネジ止め されている。 ノズルホルダ1とノズル体3との高圧接続は、中間盤13によって形成されて おり、その対向する両前面は、成形、切削および研磨によって微細加工されてい る。中間盤13の中央孔部14を介して針端部6が貫通している。 図1によれば、ノズル締結ナット10はまだ完全に締め付けられてなく、した がって中間盤13の上面15とこれに対向するノズルホルダ1の前面16との間 には隙間17が形成されている。この隙間17は、限定的な変形特性を有する鋼 鉄合金または快削鋼からなる錐形密封部材18によって架橋されている。この錐 形密封部材18は中間盤13方向に向かって拡張している錐形の脚面を備えてお り、これはこれに適合するノズルホルダ1の圧力チャネル2の開口部領域内の錐 形台座19に進入している。 ノズル締結ナット10をさらに締め付けると、錐形密封部材18は図3に示さ れているように内側に変形し、これは、台座19内に完全に収容されるまで、末 端パッキング20を形成する。図3に示された気密位置において、錐形密封部材 は、一方で台座19に対し、他方で中間盤13の上面15に対して、圧力チャネ ル2内の高圧に対抗する気密な接続を形成する。 高圧領域から低圧領域に対する密封は、図2に拡大して示されているように、 ノズルホルダ1の前面上において密封縁部が針ロックバネ室の壁部と同位置の部 分Dを介して延在することによって達成され、この密封縁部はノズルホルダ1の 前面16上の中心孔部7と一致する。これによって、追加的に針ロックバネ室の 密封処理が達成される。したがって、位置Dは0.5ないし3.0°をなす角度 γに対する分岐点を形成し、これはノズルホルダ1の前面16に相応して斜めに 延在する静止面21を規定する。静止面21は、Dにおける密封縁部を形成する 。ノズル締結ナット10を締め付け作用下において、密封縁部により、両方の圧 力チャネル2,4によって形成される高圧部分と低圧部分との間に密封効果を高 める追加的なバリアを形成し、この低圧部分はノズルホルダ1ならびにノズル体 3内の中央内部空間に接合している。 錐形密封部材18の密封作用について、図3に示されているように、これがノ ズル締 結ナット10をより強く締め付けることにしたがってごく僅かに変形するにもか かわらず、実質的に自律的中心化をなし得ることが好適である。 図4および図5には、高圧側の圧力チャネル密封が図2の部分拡大図にしたが って示されている。図4において、図2に対する相違点は、錐形密封部材18が 密封リング22によって代替されていることであり、これは実質的に2つの外側 に対向する錐形状の部材26,27からなり、その錐形面はいずれも密封リング 22の端部に向かって先細となっている。上方の部材26は図2について記述し たように圧力チャネル2の下端に収容されるが、下方の部材27は中間盤13の 上面15の圧力チャネル孔部2aの開口部23内に進入している。このように図 3のものに比して拡大された密封面によって、密封作用がさらに改善される。同 様のことが図5の変更例にも該当する。これにおいては、密封管部材25が使用 され、これは密封リング22(図4)と同様に二つの錐形状部材26,27をそ の両端に備えており、これらは空洞シリンダ状の中間部分24内に装着され、こ れは中間盤13の支持孔部29によって緊密に包囲されている。上方の部材26 は図2について記述したものと同様に圧力チャネル2の錐形台座19内に収容さ れているが、下方の部材27はノズル体3の圧力チャネル4の適宜に広がった開 口部28内に進入している。DETAILED DESCRIPTION OF THE INVENTION Injection device The invention comprises an injection nozzle holder, the pressure channel of which on the one hand is an injection pump Connected to the injection nozzle on the other side, the nozzle holder moves the nozzle pin in the vertical direction A diesel engine that is airtightly supported via an intermediate plate The present invention relates to an engine injection device.
