1257973 玖、發明說明： 【發明所屬之技術領域】 本發明係關於一種由燃料泵將儲存在燃料箱内的燃料 升壓，然後將該升壓的燃料通過燃料噴射閥向内燃機噴射 供給的燃料噴射裝置，其中尤其是關於由燃料泵和燃料喷 射閥構成的燃料供給裝置。 【先前技術】 日本專利特開2 0 0 1 — 2 2 1 1 3 7號公報中公開了一種以往 的燃料供給裝置。其中特別是前述公報的圖8中顯示了下 述内容。 即，柱塞泵和噴射嘴結合配置成一體，通過鉚接將襯套 固定配置在構成柱塞泵的泵主體下端上，形成在前述襯套 下方外周的陽螺紋與形成在構成噴射嘴的筒體上方的内周 的陰螺紋係進行螺紋嚙合，因而喷射嘴與柱塞泵結合成一 體。 【發明内容】 (發明所欲解決之問題） 根據以往之燃料供給裝置，因噴射嘴的上端直接結合配 置在柱塞泵的下端，其存在以下的缺點。 第一，在通電驅動柱塞泵時，由於配置在柱塞泵内的電 磁線圈自己發熱，該熱量從構成柱塞泵的襯套對構成喷射 嘴的筒體加熱，使喷射嘴内流動的燃料溫度上升。 根據上述，從喷射嘴内流下的燃料中發生蒸氣，該蒸氣 使從喷射嘴向進氣管内喷射的燃料量不均句、或燃料的供 6 326\總檔\93\93104896\93104896(替換)-1 1257973 給變得斷續，阻礙連續順暢的燃料的供給。 這在内燃機空轉運轉、低速運轉時不是好現象。 第二，在内燃機長期空轉運轉、高負荷低速運轉時等的 情況下，存在進氣管溫度大幅上升的現象。 一方面，由於噴射嘴的前端部一般地***進氣管内，由 此與喷嘴一體形成的柱塞泵也設置鄰近進氣管。 根據上述，進氣管上升的溫度容易作用在柱塞泵上，必 須提高自身發熱的電磁線圈的絕緣性。 例如有從最高容許溫度為9 0 °C的Y類絕緣向最高容許溫 度更高的E類絕緣（1 2 0 °C )、F類絕緣（1 5 5 C )提高的需要， 由此帶來電磁線圈的製造成本上升的情況不能令人滿意。 進而，由於進氣管的熱通過噴射嘴直接傳遞到柱塞泵 上，柱塞泵自身溫度升高，由此在柱塞泵内容易發生蒸氣。 因前述蒸氣引起的蒸氣壓縮作用，容易引起泵的排出量 的波動，保持穩定的泵性能較難。 第三，當向柱塞泵和喷射嘴中任何一方施加外力時，由 於引起另一個變形，例如向柱塞泵施加外力時，該力通過 柱塞泵的襯套使喷射嘴的筒體變形，恐怕會阻礙在筒體内 保持微小間隙向軸方向移動的提升閥體等的順暢動作。 特別是如二輪車、船外機、通用機等進氣管直接露出在 外部使用的設備中以不使用這種燃料供給裝置為佳。 第四，需要考慮使用何種固定機構將由柱塞泵、噴射嘴 構成的燃料供給裝置相對於進氣管的固定部而固定。 第五，柱塞泵和噴射嘴由襯套和筒體螺紋連接，柱塞泵 7 326\總檔\93\93104896\93104896(替換)-1 1257973 的襯套、喷嘴的筒體為了適合内燃機，當變更柱塞泵 的規格及噴嘴的噴射量規格時需要配合它而變更。由 一方變更的時候，另一方也需要同時變更。例如為使 泵的泵容量變大而增加電磁線圈的電線，當增大襯套 徑的時候，需要增大喷嘴的筒體的内徑。 鑒於上述問題，本發明主要目的為提供一種在二輪 船外機、通用機等燃料噴射裝置的使用中最適合的燃 給裝置，其中特別提供一種在遏制因設置在燃料泵内 磁線圈發生的熱量而使喷射嘴内流動的燃料變熱的同 遏制在進氣管溫度上升時燃料泵溫度的上升，而且可 正確的燃料連續而穩定地向内燃機供給的上述燃料供 置。同時提供一種不需要增大燃料泵的電磁線圈的絕 並且價格低廉的燃料供給裝置。 (解決問題之手段） 本發明的燃料供給裝置為了實現上述目的，本發明 種燃料供給裝置，係由燃料泵將燃料箱内的燃料升壓 將該被升壓的燃料通過燃料喷射閥向内燃機噴射供給 其第一特徵在於：將燃料喷射閥和燃料泵一體地安裝a 座體上的同時，燃料泵的燃料排出路和燃料噴射閥的 流入路通過穿設在該底座體内的燃料流路相連， 將具有前述燃料喷射閥和燃料泵的底座體安裝在進 管上，由底座體和進氣管支持的燃料喷射閥的喷孔向 管内開口。 本發明的第二特徵，根據本發明的第一特徵，燃料

線，係介由燃料流路而交叉配置。 本發明的第四特徵，根據本發明的第一特徵，與配置在 前述燃料泵内的電磁線圈相連的聯結器以及和配置在燃料 喷射閥内的電磁線圈相連的聯結器係朝同一外周方向設 置。 本發明的第五特徵，根據本發明的第一特徵，將高壓側 燃料過濾器配置在前述底座體内的燃料流路内。 再有本發明的第六特徵，根據本發明的第一特徵，將低 壓側燃料過濾器一體地安裝在前述燃料泵的燃料流入路 内〇 本發明的第七特徵，根據本發明的第一特徵，由合成樹 脂材料形成底座體。 (作用） 根據本發明的第一特徵，燃料泵和燃料喷射閥一體地安 裝在底座體上，同時，燃料泵的燃料排出路和燃料喷射閥 的燃料流入路通過穿設在該底座體内的燃料流路相連。 將包括前述燃料喷射閥和燃料泵的底座體安裝在進氣管 上，在燃料噴射閥的前端開口的噴孔向著進氣管内開口配 置。 在燃料录驅動時’在設置在燃料果内的電磁線圈自身發 9 326\ 總檔 \93\93104896\93104896(替換)· 1 1257973 熱時，該熱量由底座體減少，可以遏制對燃料喷射閥的熱 傳導，因而可以遏制燃料噴射閥内流動的燃料的溫度的升 高，可以大幅度減少燃料噴射閥内蒸氣的發生。 而且，燃料泵由於對應底座體的體積配置在遠離進氣管 的位置上，可以遏制由進氣管的熱量引起燃料泵溫度升 南’因而’沒有必要提南配置在燃料果内的電磁線圈的絕 緣性。 根據本發明第二特徵，由於燃料泵的燃料排出路的縱軸 線、燃料f射閥的燃料流入路的縱轴線和底座體燃料流路 的縱軸線配置在同一條直線上，所以可以提高從燃料泵向 燃料噴射閥的燃料的直進性，特別是可提高内燃機起動時 的燃料回應性。 根據本發明第三特徵，則前述燃料泵的燃料排出路的縱 軸線和燃料喷射閥的燃料流入路的縱軸線係介由底座體燃 料流路而交叉配置。 如果採用這種結構，在燃料喷射闊作動時，從燃料喷射 閥的燃料流入路向上游側發生的脈動壓力會與燃料流路衝 撞而衰減。另外在燃料泵作動時，從燃料泵的燃料排出路 向下游側發生的脈動壓力會與燃料流路衝撞而衰減。 相互發生的脈動壓力對另一方影響小，由此可將來自燃 料喷射閥脈動小的穩定的燃料供給到進氣管内。 另外，根據本發明第四特徵，由於從燃料泵向外部的聯 結器與從燃料喷射閥向外部的聯結器設置在同一外周方 向，所以可以提高與前述聯結器和外部電源相連的測量型 10 326\總檔\93\93104896\93104896(替換)-1 1257973 連接器的電連接作業性。 根據本發明第五特徵，由於將高壓側燃料過濾器設置在 底座體的燃料流路内，所以可以提高高壓側燃料過濾器的 安裝性。 根據本發明第六特徵，由於將低壓側燃料過濾器設置在 燃料果的燃料流路内*所以可以提南低壓側燃料過ί慮裔的 安裝性。 另外，根據本發明第七特徵，底座體由合成樹脂材料形 成，由於使用與金屬材料相比導熱性低的材料，所以可以 有效地遏制由燃料豕的電磁線圈發生的熱里而引起燃料f 射泵溫度升高。 【實施方式】 (實施例） 以下通過圖1對本發明的燃料供給裝置的一個實施例進 行說明。該燃料供給裝置由燃料泵P、燃料喷射閥J和底 座體B構成。 燃料泵P由下述構成。 元件符號1是由筒狀的圓筒部1 A、從圓筒部1 A下端向 外周方向延伸的下方凸緣部分1 B、從圓筒部1 A上端向外

326\總檔\93\93104896\93104896(替換)-1 1257973 此外，圓筒部件1 2固定配置在流入接頭1 5内，流入接 頭1 5固定配置在設置在線圈架1上方凸緣1 C上面的環形 上側磁極板4 B (由磁性材料製成）上。而且前述流入接頭1 5 在具有收容無填料管7上方部分的凹部的同時還包括向上 方開口的燃料流入路1 6，燃料流入路1 6的下方通過吸入 閥座1 3與穿設在圓筒部件1 2上的導向孔1 2 A流路相連。 返回來再說明可動柱塞8，可動柱塞8係使其導向筒8 A 保持微小間隙滑動自由地支持在圓筒部件1 2的導向孔1 2 A 内，由下彈簧17A和上彈簧17B在一定位置上平衡狀態地 支持。 下彈簧17A的下端繫止在固定鐵芯3的上端上，其上端 繫止在可動柱塞8中間部的下面8C上。 另外，上彈簧1 7 B的下端繫止到可動柱塞8中間部的上 面8 D上，其上端繫止到圓筒部件1

如果採用前述結構，由輛狀物1 9 一上側磁極板4 B -可動 柱塞8 —固定鐵芯3 —下側磁極板4 A —輛狀物1 9形成磁迴 路0 13 326\總檔\93\93104896\93104896(替換)-1 1257973 另外，1 9 A是趨向其它部件的安裝片部，在軛狀物1 9的 一部分上加工切口並向下側方向彎曲該加工切口部分，形 成該19A。在安裝片部19A上穿設出安裝通孔19B。 2 0是一對與電磁線圈2的繞線始端和繞線終端相連的雄 型端子針腳，該雄型端子針腳2 0向聯結器2 1的内底部突 出而被埋設。 上述聯結器2 1係由合成樹脂材料外鑄軛狀物1 9上端薄 壁部和流入接頭1 5下方外周時同時形成。 以下對燃料喷射閥J進行說明。 3 0是由合成樹脂材料形成的圓筒部3 0 A、上方凸緣3 Ο B 和下方凸緣3 0 C組成的線圈架，電磁線圈3 1纏繞在圓筒部 30A的外周上。 3 2表不由磁性材料製成的流入接頭，其包含设置在線圈 架3 0的上方凸緣3 Ο B上的上側磁極板3 2 A，同時還包含由 上側磁極板3 2 A的下面向下方突出的固定鐵芯3 2 B及由上 側磁極板3 2 A的上面向上方突出的流入管3 2 C。 由於從流入管3 2 C的上端向固定鐵芯3 2 B的下端貫通地 穿設燃料流入路3 2 D，將面臨下方的環形彈簧調整管3 3嵌 入到燃料流入路32D内。 而且，將第三密封環3 4設置在穿設在流入管3 2 C的上端 附近外周上的環形槽内，另外，將安裝用環形槽3 2 E穿設 在比第三密封環3 4更靠下的流入管3 2 C的外周上。環形槽 3 2E的橫截面形狀以D剖開狀的缺圓形狀為佳。 這是為了遏制燃料喷射閥J的轉動。 14 326\ 總檔\93\93104896\93104896(替換)-1 1257973 在前述流入接頭上側磁極板3 2 A設置在線圈架3 0的上方 凸緣3 Ο Β上的同時，固定鐵芯3 2 Β***設置在線圈架3 0 的圓筒部30Α内。 3 5表示移動自由地配置在線圈架3 0的圓筒部3 Ο Α内的 同時與固定鐵芯3 2 B的下端面相對配置的鐵心，該鐵心3 5 通過彈簧3 6向離開固定鐵芯3 2 B的方向推壓。 3 7表示由磁性材料形成的耗狀物，從大致形成在中間的 底部朝向上方地凹設線圈架收容孔3 7 B，同時向下方凹設 閥體收容孔3 7 C。 因而，包含電磁線圈3 1的線圈架3 0和流入接頭3 2的上 側磁極板3 2 A收容在軛狀物3 7的線圈架收容孔3 7 B内，在 此狀態下，將形成在輛狀物3 7上端的薄壁部向上側磁極板 3 2 A的上端向内側鉚接。 38表示在下端穿設了喷孔38A的閥體，在該閥體38内， 包括開閉噴孔3 8 A的錐形閥部3 9 A的針閥3 9可自由移動地

7的上端 薄壁部和流入接頭3 2下方外周時同時形成。 15 326\總檔\93\93104896\93104896(替換)-1 1257973 4 2表示配置在穿設在軛狀物3 7下端附近外周上的環形 槽内的第四密封環。 以下對底座體B進行說明。 底座體B包括在上方和側方延伸的安裝凸緣部5 0，從上 端5 Ο A向下端5 0 F燃料流路5 1貫穿設置。 在前述燃料流路中，向底座體B的上端5 Ο A開口的燃料 流路5 1 A係形成為可以將比燃料泵P的下側磁極板4 A更向 下方突出的固定鐵芯3***燃料流路5 1A内的直徑，在底 座體B的下端5 0 F開口的燃料流路5 1 B係形成為可以將比 燃料喷射閥J的環形槽3 2 E更向上方的流入管3 2 C***燃 料流路5 1 B内的直徑。 在底座體B的安裝凸緣部5 0上穿設安裝孔5 Ο E的同時， 形成第一螺絲孔5 Ο B，在下端5 0 F上形成第.二螺絲孔5 0 C。 另外，在本實施例中，燃料流路5 1 (在上端5 Ο A上開口的 燃料流路5 1 A、在下端5 Ο B上開口的燃料流路5 1 B )在一條 直線上形成。 然後採用下述步驟將燃料泵P和燃料喷射閥J安裝在底 座體B上。 將燃料泵P的固定鐵芯3的下部***到在底座體B的上 端5 Ο A内開口的燃料流路5 1 A内的同時，將形成在下側磁 極板4A下方的固定鐵芯3的凸緣部3A配置在底座體B的 上端5 Ο A上，在此狀態下，通過軛狀物1 9的安裝片部1 9 A 的安裝孔1 9 B，將螺絲6 0螺鎖在第一螺絲孔5 Ο B内。 如果採用前述方法，通過將構成燃料泵P的固定鐵芯3 16 326\總檔\93\93104896\93104896(替換)-1 1257973 的下方***底座體B的燃料流路51 A内，燃料泵P立設支 持在底座體B上的同時，通過由螺絲6 0將安裝片部1 9 A 螺鎖在底座體B上，遏制燃料泵P的轉動。 此外，由第一密封環6 A維持***燃料流路5 1 A内的固定 鐵芯3的外周與前述燃料流路5 1 A的内周之間的氣密性。 以下採用下述步驟將燃料噴射闊J安裝在底座體B上。 一側開口的夾子6 1嵌合配置在燃料喷射閥J的環形槽 3 2 E (形成D切口等缺圓環形槽）内，然後，流入管3 2 C*** 配置在於底座體B下端5 Ο B開口的燃料流路5 1 B内，在此 狀態下，利用對夾子61貫通而穿設的安裝孔，將螺絲6 2 螺鎖在底座體B的第二螺絲孔5 0 C上。 如果採用前述方法，通過將構成燃料噴射閥J的流入管 3 2 C***底座體B内的燃料流路51 B中，燃料喷射閥J立 設支持在底座體B上，同時夾子6 1通過螺絲6 2螺合在底 座體B上，遏制燃料喷射閥J的轉動。 此外，由第三密封環3 4維持***燃料流路5 1 B内的流入 管3 2 C的外周和燃料流路5 1 B内周之間的氣密性。 如果採用前述結構，燃料泵P —體地定位安裝在底座體 B的上端5 Ο A上，燃料噴射閥J 一體地定位安裝在底座體B 的下端50F上。 上述燃料泵P和燃料喷射閥J 一體地安裝在底座體B上 的燃料供給裝置係向著内燃機配置如下。 結合圖2進行說明，6 0表示進氣通路6 1貫通地穿設在 其内部的進氣管，進氣通路6 1的下游與内燃機E相連，其 17 326\總檔\93\93104896\93104896(替換)-1 1257973 上游與下述節流閥體相連。 另外在將燃料喷射閥J的軛狀物3 7的下端部和閥體3 8 的下端部***進氣管6 0内的同時，向進氣通路61内開口 的噴射閥支持孔6 2穿設在進氣管6 0上。而且底座體支持 部63斜向上突出地形成在進氣管60上，在底座體支持部 6 3的上端面6 3 A上形成螺絲孔6 3 B。 一方面，由於與進氣管60的進氣通路61相連的進氣通 路65穿設在前述節流閥體64内，進氣通路65由安裝在節 流閥軸6 6上的蝶型節流閥6 7開閉，節流閥軸6 6轉動自由 地安裝在節流閥體6 4内。 該節流閥軸6 6的轉動操作由駕驶者操作。 另外，前述節流閥體的進氣通路6 5的上游側連接到空氣 濾清器6 8上。也就是，由空氣濾清器6 8去除異物後的清 潔空氣通過節流閥體6 4的進氣通路6 5、進氣管6 0的進氣 通路61供給到内燃機E。此時，供給到内燃機E的空氣量 根據操作者所操縱的節流閥6 7的開合度來決定。 包括燃料泵P和燃料喷射閥J的底座體B採用下述方式 安裝在進氣管60上。 也就是，底座體B的安裝凸緣部50設置在進氣管60的 底座體支持部6 3的上端面6 3 A上，同時，包含燃料噴射閥 J的閥體3 8的軛狀物3 7的下端部***進氣管6 0的噴射闊 支持孔6 2内，在此狀態下，利用安裝凸緣部5 0的安裝孔 5 0 A，將螺絲6 3 C螺鎖在底座體支持部6 3的螺絲孔6 3 B内。 如果採用前述結構，由於底座體B固定地安裝在進氣管6 0 18 326\總檔\93\93104 896\93104896(替換)-1 1257973 上，此時，包含燃料噴射閥J的閥體3 8的軛狀物3 7的下 端部支持在噴射閥支持孔6 2内。因而，在燃料噴射閥J 的閥體3 8的下端面開口的噴孔3 8 A也在噴射閥支持孔6 2 内開口 ，噴孔3 8 A通過喷射閥支持孔6 2向進氣管6 0内的 進氣通路61内開口。 燃料配管向下述那樣執行。也就是内部儲存燃料的燃料 箱T與穿設在燃料泵P的流入接頭1 5内的燃料流入路1 6 由燃料管6 9相連。 將與E C U (電控裝置）等外部電源相連的雌型連接器嵌合 連接到燃料泵P的聯結器2 1内，同樣地與外部電源相連的 雌型連接器嵌合連接到燃料噴射閥J的聯結器4 1内。前述 ECU、雌型連接器未示於圖中。 而且，7 0表示清除從燃料箱T向燃料管6 9内供給的燃 料中的異物的淨化器，7 1表示清除從燃料箱T向燃料管6 9 内供給的燃料中的異物的低壓側過濾器。 如果選擇包括前述燃料供給裝置的燃料喷射裝置，在包 含内燃機起動動作的内燃機的運轉中，由於從ECU向燃料 泵P輸出電信號，當不向燃料泵P的電磁線圈2通電時， 可動柱塞8係保持在下彈簧1 7 A和上彈簧1 7 B的彈力保持 平衡的第一狀態下，泵室1 8係保持小容積狀態。 然後當向電磁線圈2通電時，可動柱塞8保持向固定鐵 芯3吸引移動的第二狀態，泵室1 8的室容積依可動柱塞的 移動而增大保持為大容積狀態。 根據從E C U向燃料果P輸出的電信號’可動柱塞8是根 19 326\總檔\93\93104896\93104896(替換 Η 1257973 據該電信號進行往復運動的元件，在泵室1 8的室容積增大 的狀態下，在排出逆止閥1 1閉塞排出閥座9的同時，吸入 逆止閥1 4使吸入閥座1 3敞開，因而，燃料箱T内的燃料 通過燃料管6 9吸入泵室1 8内。 另一方面，在泵室1 8的室容積變小狀態下，在吸入逆止 閥1 4閉塞吸入閥座1 3的同時，排出逆止閥1 1使排出閥座 9敞開，在泵室1 8内升壓後的燃料向燃料排出路5排出。 根據前述情況，在包含内燃機起動動作的内燃機的運轉 中，將燃料箱T内的燃料在泵室1 8内升壓，由連續的燃料 排出路5將升壓後的燃料供給到底座體B的燃料流路5 1 内〇 一方面，由於與燃料泵P相同從ECU向燃料喷射閥J輸 出電信號，當電磁線圈31通電時，鐵心3 5對抗彈簧3 6 的彈力吸引向固定鐵芯3 2 B，針閥3 9的錐形閥部3 9 A向喷 孔3 8 A敞開。 因而，由於針閥3 9係依來自E C U的噴射信號（通電時間） 向喷孔3 8 A敞開，在底座體B的燃料流路5 1内升壓後的燃 料通過喷孔3 8 A向進氣管6 0的進氣通路6 1内喷射供給。 而且，供給到内燃機的空氣量係依節流閥6 7的開合度控 制供給，通過由燃料喷射閥J供給且控制的燃料和由節流 閥6 7控制的空氣，可以使内燃機進行適合的運轉。 根據本發明前述燃料供給裝置，由於預先將燃料泵P和 燃料噴射閥J安裝在底座體B上而形成，由將底座體B安 裝在進氣管6 0上可將燃料供給系統的部件全部安裝在車 20 326\總檔\93\93104896\93104896(替換)-1 1257973 輛上，可以極大地提高車輛的組裝性。 這對如二輪車那樣安裝空間受到極大限制的車相當有 效。 而且，由於燃料管6 9的連接也可以是僅將燃料泵P的燃 料流路1 6和燃料箱T相連，可以提高燃料配管的設計自由 度，同時可以提高該配管連接作業性。 而且，與燃料泵P和燃料喷射閥J相連的升壓燃料流動 的高壓燃料配管由底座體B内燃料流路5 1構成，因此無需 特別考慮燃料配管的耐壓。特別是，底座體B内形成有流 動有升壓後燃料的燃料流路5 1的結構，係用在燃料供給系 統直接地露在外部的二輪車較佳。 也就是即使與障礙物衝撞損傷的危險也較少且提高美 觀。 而且，如果選擇使用電磁線圈2的燃料泵P，由於泵驅 動時電磁線圈2自身發熱，雖然在燃料泵P和燃料噴射閥 J接近配置時，由電磁線圈2發生的熱量作用在燃料喷射 閥J上，存在於燃料喷射閥J内流動的燃料溫度上升的傾 向，如果選擇本發明，由於燃料泵P和燃料喷射閥J通過 底座體B連接，所以可以遏制由燃料泵P的電磁線圈2引 起的對燃料噴射閥J的加熱。 如果選擇前述結構，可以遏制在燃料喷射閥J内流動的 燃料中蒸氣的發生，而且，可將正確的燃料連續地向進氣 管61内供給。 此時，底座體B的材料是導熱性比金屬材料低的合成樹 21 326\總檔\93\93104 896\93104896(替換)-1 1257973 脂材料。例如尼龍樹脂、環氧樹脂，如果使用對聚苯硫， 效果更好。 而且當内燃機處於低速運轉時或高負荷低速運轉等狀態 時，雖然進氣管6 0的溫度極大地升高，在本發明中，燃料 泵P和燃料喷射閥J不直接相連，燃料泵P通過底座體B 與燃料喷射閥J相連。 根據前述結構，燃料泵P可以在相當於底座體B的厚度 t的距離遠離進氣管60設置。及底座體B位於進氣管60 和燃料泵P之間，可以遏制來自進氣管6 0的熱量引起燃料 泵P的溫度升高。因此可以使用絕緣性低的電磁線圈2， 獲得降低電磁線圈製造成本的效果。而且，如上述，由合 成樹脂材料製成底座體B，可以更加提高前述效果。 而且在搭載在車輛上時，存在向沿上方突出的燃料泵P 或向下方突出的燃料喷射閥J上施加外力的情況。例如向 燃料泵P施加外力，即使***在底座體B上端5 0 A開口的 燃料流路51A内的燃料泵P的固定鐵芯3變形，該變形不 直接地給予燃料喷射閥J任何影響，沒有嚴重影響燃料噴 射閥J的動作。特別是，該設備較佳應用於露出外部配置 的二輪車。 而且，由於燃料泵P和燃料噴射閥J安裝在貫通的安裝 部件也就是底座體B上，所以可以簡化固定支持它們的固 定機構。 另外，如圖1所示，由於穿設在燃料泵P的固定鐵芯3 上的燃料排出路5的縱軸線X-X、穿設·在燃料喷射閥J的 22 326\總檔\93\93104896\93104896(替換)-1 1257973 流入接頭3 2上的燃料流入路3 2 D的縱軸線Υ - Υ、穿設在底 座體Β上的燃料流路5 1的縱軸線Ζ - Ζ設置在同一條直線 上，所以可以提高從燃料泵Ρ向燃料噴射閥J的燃料直進 性，可以提高燃料供給的應答性。 燃料泵Ρ的排出壓力比以往技術的排出壓力（3 0 0 k P a ) 低，例如可以提高使用1 Ο 0 k P a的燃料泵P排出壓力的電磁 柱塞果等中的起動時燃料的供給性。此外，前述軸線之間 關係在圖3中顯示。 如圖1所示，燃料泵Ρ的聯結器21和燃料噴射閥J的聯 結器4 1是向同一外周方向設置的元件，與E C U等外部電源 相連的測量型連接器與前述聯結器連接時可以從同一方向 進行連接，可以提高作業性。 這特別是如二輪車那樣對安裝空間受強烈限制的車比較 有效。 而且’清除包含在從燃料果Ρ輸向燃料嘴射閥J的燃料 中的異物的高壓側燃料過濾器7 2位於底座體Β的燃料流路 5 1内，且設置在燃料泵Ρ的固定鐵芯3的下端與燃料喷射 閥J的流入接頭3 2的上端之間，可以非常容易地配置高壓 側燃料過濾器7 2。 也就是，不需要針對高壓側燃料過濾器7 2的配管連接。 不需要圍繞高壓側燃料過濾器7 2的周圍的殼體。通過將燃 料泵Ρ從底座體Β上拆下，高壓側燃料過濾器7 2可以非常 容易地進行維修作業。 此外，雖然考慮將高壓側燃料過濾器72設置在前述固定 23 326\總檔\93\93104896\93104896(替換)· 1 1257973 鐵芯3的燃料排出路5内，或設置在燃料噴射閥J的流入 接頭3 2的燃料流入路3 2 D内，如果採用前述結構，由於高 壓側燃料過濾器7 2的過濾面積由前述流路路徑限制，所以 難以獲得充分的過濾面積。 如果將高壓側燃料過濾器7 2設置在燃料流入路3 2 D内， 就不會受前述限制，可以選擇適合的高壓側燃料過濾器 Ί2。 以下根據圖4對本發明燃料供給裝置的第二實施例進行 說明。此外，燃料泵P和燃料喷射閥J與圖1實施例相同， 相同結構使用相同元件符號，並省略說明。 底座體8 0包括面臨左方的側方凸緣部8 Ο A和面臨水平方 向的水平凸緣8 Ο B，在側方凸緣部8 Ο A上形成用於螺紋連 接燃料泵P的第一螺絲孔8 0 C，在水平凸緣8 Ο B形成用於 安裝進氣管的安裝孔8 0 D以及用於安裝燃料喷射閥J的第 二螺絲孔8 Ο E。 此外，在朝向側方凸緣80A的左端面80F上穿設出形成 燃料流路8 1的左方燃料流路8 1 A的開口 ，朝向水平凸緣 8 Ο B的下端面8 0 G穿設出形成燃料流路8 1的垂直方向燃料 流路8 1 B的開口。 因而，左方的燃料流路8 1 A的縱軸線X - X和垂直方向燃 料流路8 1 B的縱轴線Z - Z在底座體B内垂直相交。 將燃料泵P的固定鐵芯3***左方的燃料流路8 1 A内， 在此狀態下，燃料泵P的安裝部1 9 A通過螺絲6 0螺紋嚙合 在第一螺絲孔8 0 C，因而，燃料泵P固定在底座體B的側 24 326\總檔\93\93104896\93104896(替換)-1 1257973 方凸緣80A上。 另一方面，燃料噴射閥J的流入接頭3 2的流入管3 2 C ***垂直方向燃料流路8 1 B内，在此狀態下，螺絲6 2通過 夾子6 1螺鎖在第二螺絲孔8 Ο E内，而且，燃料喷射閥J 固定在底座體B的水平凸緣80B上。 採用前述結構，穿設在燃料泵P的固定鐵芯3上的燃料 流路5的縱軸線X - X係沿左方的燃料流路8 1 A而配置在水 平方向，穿設在燃料噴射閥J的流入管32C内的燃料流入 路3 2 D的縱軸線Z — Z係沿垂直方向燃料流路8 1 B而配置在 垂直方向，燃料排出路5和燃料流入路3 2 D通過左方燃料 流路8 1 A和垂直方向燃料流路8 1 B交叉配置。 如果採用前述結構，雖然由燃料泵P的驅動而在泵内發 生的脈動壓力通過燃料排出路5作用在左方的燃料流路 8 1 A内，但是該脈動壓力會與交叉垂直方向的燃料流路8 1 B 的側壁衝撞而衰減。 一方面，雖然藉由燃料喷射閥J以開閉喷孔3 8 A而使在 燃料噴射閥J發生的脈動壓力通過燃料流入路3 2 D作用在 垂直方向燃料流路8 1 B内，但是該脈動壓力會與交叉左方 燃料流路8 1 A的側壁衝撞而衰減。從而，由於可以減少在 相互機器内發生的脈動壓力對其他機器部分的作用，所以 可以獲得良好地維持燃料泵P的泵性能和燃料喷射閥J的 排出性能的效果。 以下結合圖5對本發明第三實施例進行說明。 此外，與圖1相同部分使用相同元件符號，省略對其的 25 326\總檔\93\93104896\93104896(替換)-1 1257973 說明。 9 0是低壓側燃料過濾器，具有下述結構。 9 1是下方開口且在側壁包括燃料流入路9 2的有底的杯 狀過濾殼體，9 3是閉塞前述過濾殼體的下方開口的過濾 罩。 在前述過濾罩的中心部設置了上下方向延伸的筒部 9 3 A，在筒部9 3 A上穿設從上端向下端的流路9 3 D。 此外在下方延伸的筒部9 3 A的外周上形成陽螺紋9 3 E。 此外，過濾罩9 3的外周部分向内鉚接在過濾殼體9 1的 外周凸緣上，因而，過濾殼體9 1和過濾罩9 3密閉地形成。 9 4是構成筒狀的過濾體，平板狀上板9 4 A和下板9 4 B由 環形濾紙9 4 C相連，上筒部9 3 A傳入配置在過濾體9 4的内 側（濾紙9 4 C的内側）。此外，過濾體9 4由縮設在上板9 4 A 和過濾殼體9 1底部之間的彈簧9 5推壓在過濾罩9 3上並固 定。 此外，在燃料泵P的上方突出的流入接頭1 5在上端具 有凸緣1 5 A，穿設在流入接頭1 5上的燃料流入路1 6通過 陰螺紋1 5 B在凸緣1 5 A上端面開口。 因而，通過將筒部9 3 A的陽螺紋9 3 E螺紋嚙合在流入接 頭1 5的陰螺紋1 5 B上，前述低壓側燃料過濾器9 0螺紋固 定在燃料泵P的流入接頭1 5的凸緣1 5 A上。 而且，低壓側燃料過濾器9 0的燃料流入路9 2保持燃料 管6 0，與燃料箱T相連。 因而，一旦驅動燃料泵P，燃料箱T内的燃料通過燃料 26 326\總檔\93\93104896\93104896(替換)·1 1257973 管6 Ο、燃料流入路9 2流入過濾殼體9 1内，該燃料由過濾 體9 4的濾紙9 4 C去除異物，從在過濾體9 4内開口的流路 9 3 D向燃料泵Ρ的燃料流入路1 6供給乾淨的燃料。 如果採用前述實施例，由於低壓側燃料過濾器9 0與燃料 泵Ρ —體設置，燃料管6 9也可以將低壓側燃料過濾器9 0 的燃料流入路9 2和燃料箱Τ相連，燃料管6 9是單純的， 可以簡化連接作業。 通過將底座體Β從進氣管6 0上拆下，可以暫時將低壓側 燃料過濾器9 0取下，可以提高前述過濾器的維修性。 通過將低壓側燃料過濾器9 0直接配置在燃料泵Ρ上，可 以具有由低壓側燃料過濾器9 0内的燃料對燃料泵Ρ進行冷 卻的效果。 本發明的燃料泵Ρ可以是稱作由向電磁線圈通電構成泵 作用的電動型燃料泵的容積型泵、非容積型泵。 另外，也可以代替進氣管6 0，將底座體Β安裝在節流閥 體64上。 而且，燃料噴射闊J的結構並不侷限於實施例，燃料噴 射閥J和燃料泵Ρ在底座體Β上的安裝方法並不侷限於實 施例。 (發明效果） 根據前述本發明的燃料供給裝置，由燃料泵將燃料箱内 的燃料升壓，在將升壓後的燃料通過燃料喷射閥向内燃機 喷射供給的燃料供給裝置内，將燃料喷射閥J和燃料泵Ρ 一體地安裝在底座體Β上，同時，燃料泵的燃料排出路和 27 326\總檔\93\93104896\93104896(替換)-1 1257973 燃料噴射閥的燃料流入路通過穿設在底座體内的燃料流路 相連。 將包括前述燃料喷射閥和燃料泵的底座體安裝在進氣管 上，由於由底座體和進氣管支持的燃料噴射閥的噴孔向進 氣管内開口，所以如果將由燃料泵、燃料噴射閥、底座體 組成的燃料供給系統部件安裝在車輛上，則可以提高二輪 車等安裝空間極度限制的車輛的組裝性。 由於燃料管也可以與燃料泵和燃料箱相連，提高了燃料 配管的設計自由度，而且可以提高配管的連接性。 從燃料果向燃料f射閥升壓後的燃料由於保持在形成在 底座體内的燃料流路内，所以無需特別考慮燃料配管的耐 壓性，在燃料配管直接暴露在外部的二輪車、船外機、通 用機等中採用本發明的燃料供給裝置特別有效。 在燃料泵驅動時，燃料泵内電磁線圈自己發熱而發生的 熱量由底座體減少，由於可以遏制對燃料喷射閥的加熱， 因而可以遏制燃料噴射閥内流動的燃料内發生蒸氣，從燃 料噴射闊可以正確穩定連續地向内燃機供給燃料。 而且，由於燃料泵可以配置的與進氣管之間的距離相當 於底座體的厚度，所以可以遏制由進氣管的熱量引起燃料 泵溫度升高，在確保燃料泵排出量穩定的同時，可以採用 絕緣性低的便宜的電磁線圈。 當向從底座體突出配置的燃料泵、燃料喷射閥的一個施 加外力時，即使底座體上的設備支持部分變形，其他設備 支持部分不變形，以將這種設備應用在直接露出外部的二 28 326\總檔\93\93104896\93104896(替換)-1 1257973 輪車上為佳。 由於燃料泵和燃料噴射閥安裝在同一個安裝部件也就是 底座體上，所以可以簡化固定機構。 如果前述燃料泵的燃料排出路的縱軸線、燃料喷射閥的 燃料流入路的縱軸線、燃料流路的縱軸線配置在同一條直 線上，可以提高從燃料泵向燃料噴射閥的燃料的直進性， 特別是提高内燃機起動時的回應性，在使用電磁柱塞泵等 時，獲得排出壓力較低的效果。 如果前述燃料泵的燃料排出路的縱軸線、燃料喷射閥的 燃料流入路的縱軸線通過燃料流路的縱軸線交叉配置，由 於由燃料泵脈動引起的脈動壓力以及由燃料噴射閥動作引 起的脈動壓力分別與燃料流路衝撞而衰減，所以燃料泵的 泵排出性能和燃料噴射閥的排出性能穩定，可以進行良好 地維持。 如果選擇與配置在前述燃料泵内的電磁線圈相連的聯 結器、與配置在前述燃料喷射閥内的電磁線圈相連的聯結 器設置在同一外周方向，由於可以提高與外部電源相連的 測量型連接器和燃料泵的聯結器的連接拆卸作業性和外部 電源相連的測量型連接器和燃料喷射閥的聯結器的連接拆 卸作業性，所以應用在安裝空間狹窄限制的二輪車内為佳。 如果在前述底座體内的燃料流路内設置高壓側燃料過 濾器，在不需要與高壓側燃料過濾器相對的配管連接的同 時，也不需要圍繞高壓側燃料過濾器的殼體，此外，高壓 側燃料過滤器的過濾、面積的選擇不受限制，可以設定適合 29 326\總檔\93\93104896\93104896(替換)-1 1257973 的過濾面積。 如果選擇將低壓側燃料過濾器一體地設置在前述燃料 泵的燃料流入路内，由於燃料管可以僅與低壓側燃料過濾 器的燃料流入路和燃料箱相連，所以在大幅度簡化燃料配 管的作業性的同時，通過將底座體從進氣管上拆卸下，可 以同時進行低壓側燃料過濾器的維護。此外，由低壓側燃 料過濾器内的燃料可以對燃料泵進行冷卻，可以遏制燃料 泵溫度的升高。 另外，如果選擇由合成樹脂材料形成前述底座體，因底 座體由燃料泵的電磁線圈發生熱量所發揮的作用可以降 低，難以向燃料噴射閥傳送熱量，在更加提高從燃料喷射 閥的排出正確性和穩定性的同時，進氣管加熱時，進氣管 的熱量所發揮的作用底座體減小，難以向燃料泵傳送熱 量，可以更加提高從燃料泵排出的正確性和穩定性。 【圖式簡單說明】 圖1為顯示本發明之燃料供給裝置的一個實施例之縱剖 面圖。 圖2顯示將本發明的燃料供給裝置安裝在内燃機上的狀 態之燃料喷射裝置。 圖3為顯示圖1中的固定鐵芯、燃料流路、流入接頭的 位置關係之狀態圖。 圖4為顯示本發明燃料供給裝置的其他實施例之縱剖面 圖。

Description: [Technical Field] The present invention relates to a fuel injection pump that boosts fuel stored in a fuel tank by a fuel pump, and then supplies the boosted fuel to an internal combustion engine through a fuel injection valve The device, in particular with regard to a fuel supply device consisting of a fuel pump and a fuel injection valve. [Prior Art] A conventional fuel supply device is disclosed in Japanese Laid-Open Patent Publication No. 2000-221. Among them, the following is particularly shown in Fig. 8 of the aforementioned publication. That is, the plunger pump and the injection nozzle are integrally disposed in combination, and the bushing is fixedly disposed on the lower end of the pump main body constituting the plunger pump by caulking, and a male screw formed on the outer periphery of the bushing and a cylinder formed in the injection nozzle are formed. The upper inner circumference of the female thread is threadedly engaged, so that the injection nozzle is integrated with the plunger pump. DISCLOSURE OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION According to the conventional fuel supply device, since the upper end of the injection nozzle is directly coupled to the lower end of the plunger pump, there are the following disadvantages. First, when the plunger pump is energized to drive, since the electromagnetic coil disposed in the plunger pump generates heat by itself, the heat is heated from the bushing constituting the plunger pump to the cylinder constituting the injection nozzle, so that the fuel flowing in the injection nozzle The temperature rises. According to the above, steam is generated from the fuel flowing down from the injection nozzle, and the vapor causes the amount of fuel injected from the injection nozzle into the intake pipe to be uneven, or the fuel supply is 6 326\total gear\93\93104896\93104896 (replacement) -1 1257973 The supply becomes intermittent, hindering the supply of continuous and smooth fuel. This is not a good phenomenon when the internal combustion engine is idling and running at low speed. Second, in the case of long-term idling operation of the internal combustion engine and high-speed low-speed operation, there is a phenomenon in which the temperature of the intake pipe is greatly increased. On the one hand, since the front end portion of the injection nozzle is generally inserted into the intake pipe, the plunger pump integrally formed with the nozzle is also disposed adjacent to the intake pipe. According to the above, the temperature at which the intake pipe rises easily acts on the plunger pump, and the insulation of the electromagnetic coil which is self-heating must be improved. For example, there is a need to increase the Class E insulation with a maximum allowable temperature of 90 °C to Class E insulation (1 2 0 °C) and Class F insulation (1 5 5 C) with a higher maximum allowable temperature. The increase in the manufacturing cost of the electromagnetic coil is unsatisfactory. Further, since the heat of the intake pipe is directly transmitted to the plunger pump through the spray nozzle, the temperature of the plunger pump itself rises, whereby vapor is easily generated in the plunger pump. Due to the vapor compression caused by the aforementioned vapor, it is easy to cause fluctuations in the discharge amount of the pump, and it is difficult to maintain stable pump performance. Third, when an external force is applied to either one of the plunger pump and the injection nozzle, the force is deformed by the bushing of the plunger pump by the bushing of the plunger pump when another deformation is caused, for example, when an external force is applied to the plunger pump. I am afraid that it will hinder the smooth movement of the poppet valve body and the like that keep the small gap moving in the axial direction in the cylinder. In particular, it is preferable that the intake pipe such as a two-wheeled vehicle, an outboard motor, or a general-purpose machine is directly exposed to an externally used device so as not to use such a fuel supply device. Fourth, it is necessary to consider which fixing mechanism is used to fix the fuel supply device composed of the plunger pump and the injection nozzle with respect to the fixing portion of the intake pipe. Fifth, the plunger pump and the injection nozzle are screwed by the bushing and the cylinder, and the plunger pump 7 326\total gear \93\93104896\93104896 (replacement)-1 1257973 bushing, nozzle cylinder for the internal combustion engine, When the specification of the plunger pump and the injection amount specification of the nozzle are changed, it is necessary to change it. When one party changes, the other party also needs to change at the same time. For example, in order to increase the pump capacity of the pump and increase the wire of the electromagnetic coil, when the diameter of the bushing is increased, it is necessary to increase the inner diameter of the barrel of the nozzle. In view of the above problems, the main object of the present invention is to provide a fuel supply device which is most suitable for use in the use of a fuel injection device such as a two-wheeled outboard motor or a general purpose machine, and particularly provides a heat generation device for suppressing heat generated by a magnetic coil disposed in a fuel pump. On the other hand, when the fuel flowing in the injection nozzle is heated, the temperature of the fuel pump rises when the temperature of the intake pipe rises, and the fuel can be continuously and stably supplied to the internal combustion engine. At the same time, there is provided an inexpensive and inexpensive fuel supply device that does not require an increase in the electromagnetic coil of the fuel pump. (Means for Solving the Problem) In order to achieve the above object, the fuel supply device of the present invention boosts the fuel in the fuel tank by the fuel pump, and injects the boosted fuel into the internal combustion engine through the fuel injection valve. The first feature of the supply is that the fuel injection valve and the fuel pump are integrally mounted on the a seat body, and the fuel discharge path of the fuel pump and the inflow path of the fuel injection valve are connected by a fuel flow path that is bored in the base body. The base body having the fuel injection valve and the fuel pump described above is mounted on the inlet pipe, and the injection hole of the fuel injection valve supported by the base body and the intake pipe opens into the pipe. According to a second feature of the present invention, in accordance with the first feature of the present invention, the fuel 326\total gear\93\93104896\93104896 (replacement of the pump of the 此, when the direct drive of the plunger is supplied with electricity, The first and the second, the vertical axis of the fuel exhaust passage of the fuel injection valve, the longitudinal axis of the fuel inflow path of the fuel injection valve, and the longitudinal axis of the fuel flow path are disposed on the same straight line. According to a third feature of the present invention, the longitudinal axis of the fuel discharge path of the fuel pump and the longitudinal axis of the fuel inflow path of the fuel injection valve are intersected by the fuel flow path. The fourth feature of the present invention According to the first feature of the present invention, the coupler connected to the electromagnetic coil disposed in the fuel pump and the coupler connected to the electromagnetic coil disposed in the fuel injection valve are disposed in the same outer circumferential direction. According to a first feature of the present invention, a high-pressure side fuel filter is disposed in a fuel flow path in the base body. Further, according to a sixth feature of the present invention, the first aspect according to the present invention According to a seventh aspect of the present invention, the low-pressure side fuel filter is integrally mounted in the fuel inflow path of the fuel pump, and according to the first feature of the present invention, the base body is formed of a synthetic resin material. In a first feature, the fuel pump and the fuel injection valve are integrally mounted on the base body, and at the same time, the fuel discharge path of the fuel pump and the fuel inflow path of the fuel injection valve are connected by a fuel flow path that is bored in the base body. The fuel injection valve and the base body of the fuel pump are mounted on the intake pipe, and the injection hole opened at the front end of the fuel injection valve is disposed toward the opening in the intake pipe. When the fuel is being driven, the electromagnetic coil itself is disposed in the fuel electrode. Hair 9 326\ Total gear \93\93104896\93104896 (replacement) · 1 1257973 When the heat is reduced, the heat is reduced by the base body, which can suppress the heat conduction to the fuel injection valve, thereby suppressing the temperature of the fuel flowing in the fuel injection valve. The increase can greatly reduce the occurrence of steam in the fuel injection valve. Moreover, the fuel pump is disposed away from the intake pipe due to the volume of the corresponding base body. The position of the fuel pump can be suppressed by the heat of the intake pipe. Therefore, it is not necessary to mention the insulation of the electromagnetic coil disposed in the fuel fruit. According to the second feature of the present invention, the fuel pump is discharged. The longitudinal axis of the road, the longitudinal axis of the fuel inflow path of the fuel injection valve, and the longitudinal axis of the base body fuel flow path are arranged on the same straight line, so that the straightness of the fuel from the fuel pump to the fuel injection valve can be improved, in particular According to a third feature of the present invention, the longitudinal axis of the fuel discharge path of the fuel pump and the longitudinal axis of the fuel inflow path of the fuel injection valve are intersected by the base body fuel flow path. According to this configuration, when the fuel injection is wide, the pulsating pressure generated from the fuel inflow path of the fuel injection valve to the upstream side collides with the fuel flow path to be attenuated. Further, when the fuel pump is actuated, the pulsating pressure generated from the fuel discharge path of the fuel pump to the downstream side collides with the fuel flow path and is attenuated. The mutual occurrence of the pulsating pressure has a small influence on the other side, whereby the stable fuel having a small pulsation from the fuel injection valve can be supplied into the intake pipe. Further, according to the fourth aspect of the present invention, since the coupling from the fuel pump to the outside and the coupling from the fuel injection valve to the outside are disposed in the same outer circumferential direction, the measurement type 10 326 connected to the aforementioned coupling and the external power source can be improved. \总档\93\93104896\93104896 (replacement)-1 1257973 Connector electrical connection workability. According to the fifth feature of the present invention, since the high-pressure side fuel filter is disposed in the fuel flow path of the base body, the mountability of the high-pressure side fuel filter can be improved. According to the sixth feature of the present invention, since the low-pressure side fuel filter is disposed in the fuel flow path of the fuel fruit*, it is possible to improve the mountability of the low-pressure side fuel in the south. Further, according to the seventh feature of the present invention, the base body is formed of a synthetic resin material, and since a material having a lower thermal conductivity than the metal material is used, it is possible to effectively suppress the heat generated by the electromagnetic coil of the fuel crucible and cause the fuel f to be emitted. The pump temperature has risen. [Embodiment] (Embodiment) An embodiment of a fuel supply device of the present invention will be described below with reference to Fig. 1 . This fuel supply device is composed of a fuel pump P, a fuel injection valve J, and a base body B. The fuel pump P is composed of the following. The symbol 1 is a cylindrical portion 1A having a cylindrical shape, a lower flange portion 1B extending from the lower end of the cylindrical portion 1A in the outer circumferential direction, and an upper flange portion 1 extending from the upper end of the cylindrical portion 1A toward the outer circumferential direction. A bobbin composed of C, the electromagnetic coil 2 is wound around the outer circumference of the cylindrical portion 1A. 3 is a fixed iron core composed of a magnetic material, the upper end of which is inserted into a lower portion of the inner circumference of the cylindrical portion 1A of the bobbin 1, and is disposed on the lower side of the lower surface of the lower flange portion 1 B of the bobbin 1 The inner peripheral portion of the magnetic pole plate 4 A (formed of magnetic 11 326 \ total gear \93\93104896\93104896 (replacement)-1 1257973 material) is electromagnetically coupled to the outer circumference of the lower end portion of the fixed iron core. The fixed iron core is formed such that its upper end portion is inserted into the cylindrical portion 1A of the bobbin 1 and extends, and the lower end portion projects downward from the lower side magnetic pole plate 4A.

Device. If the fuel injection device including the fuel supply device described above is selected, in the operation of the internal combustion engine including the engine starting operation, since the electric signal is output from the ECU to the fuel pump P, when the electromagnetic coil 2 of the fuel pump P is not energized, the movable plunger The 8 series is maintained in a first state in which the elastic force of the lower spring 1 7 A and the upper spring 1 7 B is balanced, and the pump chamber 18 is kept in a small volume state. Then, when the electromagnetic coil 2 is energized, the movable plunger 8 maintains the second state of suction and movement to the fixed iron core 3, and the chamber volume of the pump chamber 18 is increased and maintained in a large volume state in accordance with the movement of the movable plunger. According to the electric signal output from the ECU to the fuel fruit P, the movable plunger 8 is the root 19 326\the main gear \93\93104896\93104896 (replaces the element that reciprocates according to the electric signal, in the chamber of the pump chamber 18 In the state where the volume is increased, while the discharge check valve 1 1 closes the discharge valve seat 9, the check valve 14 is sucked to open the suction valve seat 13, and thus the fuel in the fuel tank T is sucked through the fuel pipe 69. On the other hand, in a state where the chamber volume of the pump chamber 18 is reduced, the suction check valve 14 is closed while the suction check valve 14 is closed, and the check valve 1 is discharged to discharge the valve seat 9 The fuel that has been boosted in the pump chamber 18 is discharged to the fuel discharge path 5. According to the above, in the operation of the internal combustion engine including the starting operation of the internal combustion engine, the fuel in the fuel tank T is boosted in the pump chamber 18. The pressurized fuel is supplied from the continuous fuel discharge path 5 to the fuel flow path 5 1 of the base body B. On the one hand, since the fuel pump P outputs an electric signal from the ECU to the fuel injection valve J as the fuel pump P, the electromagnetic coil is used. When the power is turned on 31, the iron core 3 5 is attracted to the fixed iron core 3 2 B against the elastic force of the spring 3 6 , the needle The conical valve portion 3 9 A of 3 9 is opened to the injection hole 38 8 A. Thus, since the needle valve 39 is opened to the injection hole 38 A according to the injection signal (energization time) from the ECU, the fuel in the base body B The fuel boosted in the flow path 51 is injected into the intake passage 61 of the intake pipe 60 through the injection hole 38 A. Further, the amount of air supplied to the internal combustion engine is based on the opening degree of the throttle valve 67. By controlling the supply, the internal combustion engine can be appropriately operated by the fuel supplied and controlled by the fuel injection valve J and the air controlled by the throttle valve 67. According to the foregoing fuel supply device of the present invention, since the fuel pump P and the fuel are injected in advance The valve J is formed by being mounted on the base body B. The components of the fuel supply system can be all installed in the vehicle 20 326\main gear\93\93104896\93104896 (replacement) by mounting the base body B on the intake pipe 60. 1 1257973, it can greatly improve the assembly of the vehicle. This is quite effective for a car with a very limited installation space like a two-wheeled vehicle. Moreover, since the connection of the fuel pipe 69 can also be a fuel flow path only for the fuel pump P. 1 6 is connected to the fuel tank T to improve combustion The degree of freedom in designing the material piping can improve the piping connection workability. Further, the high-pressure fuel piping through which the boosted fuel connected to the fuel pump P and the fuel injection valve J flows is constituted by the fuel flow path 51 in the base body B, It is not necessary to particularly consider the withstand voltage of the fuel pipe. In particular, the structure in which the fuel flow path 51 through which the boosted fuel flows is formed in the base body B is preferably used in a two-wheeled vehicle in which the fuel supply system is directly exposed to the outside. That is, even if the collision with the obstacle is less dangerous, the appearance is improved. Further, if the fuel pump P of the electromagnetic coil 2 is selected, since the electromagnetic coil 2 itself generates heat when the pump is driven, although the fuel pump P and the fuel injection valve J are disposed close to each other, heat generated by the electromagnetic coil 2 acts on the fuel injection valve J. In the above, the temperature of the fuel flowing in the fuel injection valve J tends to rise. If the present invention is selected, since the fuel pump P and the fuel injection valve J are connected through the base body B, it is possible to suppress the electromagnetic coil 2 caused by the fuel pump P. Heating of the fuel injection valve J. If the foregoing configuration is selected, the occurrence of vapor in the fuel flowing in the fuel injection valve J can be suppressed, and the correct fuel can be continuously supplied into the intake pipe 61. At this time, the material of the base body B is a synthetic tree having a lower thermal conductivity than the metal material 21 326\total file\93\93104 896\93104896 (replacement)-1 1257973 fat material. For example, nylon resin, epoxy resin, if the use of polyphenylene sulfide, the effect is better. Further, when the internal combustion engine is in a state of low speed operation or high load low speed operation or the like, although the temperature of the intake pipe 60 is greatly increased, in the present invention, the fuel pump P and the fuel injection valve J are not directly connected, and the fuel pump P passes. The base body B is connected to the fuel injection valve J. According to the foregoing configuration, the fuel pump P can be disposed away from the intake pipe 60 at a distance corresponding to the thickness t of the base body B. And the base body B is located between the intake pipe 60 and the fuel pump P, and can suppress the heat from the intake pipe 60 to cause the temperature of the fuel pump P to rise. Therefore, the electromagnetic coil 2 having low insulation can be used, and the effect of reducing the manufacturing cost of the electromagnetic coil can be obtained. Further, as described above, the base body B is made of a synthetic resin material, and the above effects can be further enhanced. Further, when mounted on a vehicle, there is a case where an external force is applied to the fuel pump P that protrudes upward or the fuel injection valve J that protrudes downward. For example, an external force is applied to the fuel pump P, and even if the fixed iron core 3 of the fuel pump P inserted in the fuel flow path 51A opened at the upper end of the base body B 0 A is deformed, the deformation does not directly affect the fuel injection valve J, and there is no influence. Seriously affects the action of the fuel injection valve J. In particular, the device is preferably applied to a two-wheeled vehicle that exposes an external configuration. Further, since the fuel pump P and the fuel injection valve J are mounted on the through-mounting member, that is, the base body B, the fixing mechanism for supporting them can be simplified. Further, as shown in Fig. 1, the longitudinal axis XX of the fuel discharge path 5 which is bored on the fixed iron core 3 of the fuel pump P, and the length of the fuel injection valve J are 22 326\the total gear \93\93104896\ 93104896 (replacement)-1 1257973 The longitudinal axis 燃料 of the fuel inflow path 3 2 D flowing into the joint 3 2 Υ - 纵, the longitudinal axis of the fuel flow path 5 1 penetrating the base body Ζ - Ζ is set in the same straight line Therefore, the fuel straightness from the fuel pump to the fuel injection valve J can be improved, and the responsiveness of the fuel supply can be improved. The discharge pressure of the fuel pump 低 is lower than that of the prior art (3 0 0 k P a ), for example, it is possible to increase the fuel at the start of the fuel plunger using the fuel pump P discharge pressure of 1 Ο 0 k Pa. Supplyability. Further, the relationship between the aforementioned axes is shown in Fig. 3. As shown in Fig. 1, the coupler 21 of the fuel pump port and the coupler 41 of the fuel injection valve J are components provided in the same outer circumferential direction, and the measurement type connector connected to an external power source such as an ECU can be connected to the aforementioned coupler. Connecting from the same direction can improve workability. This is especially effective for a vehicle with a strong installation space, such as a two-wheeled vehicle. Further, the high-pressure side fuel filter 72 that removes the foreign matter contained in the fuel from the fuel cannon to the fuel injection valve J is located in the fuel flow path 51 of the base body, and is fixed to the fuel pump. The high pressure side fuel filter 72 can be disposed very easily between the lower end of the core 3 and the upper end of the inflow joint 3 2 of the fuel injection valve J. That is, the piping connection to the high pressure side fuel filter 72 is not required. There is no need to surround the casing around the high pressure side fuel filter 72. The high-pressure side fuel filter 72 can be easily repaired by removing the fuel pump Ρ from the base body. Further, it is considered that the high-pressure side fuel filter 72 is disposed in the fuel discharge path 5 of the aforementioned fixed 23 326\total gear\93\93104896\93104896 (replacement)·1 1257973 iron core 3, or provided in the fuel injection valve J In the fuel inflow path 3 2 D flowing into the joint 3 2, if the above configuration is employed, since the filtration area of the high pressure side fuel filter 72 is restricted by the above-described flow path, it is difficult to obtain a sufficient filtration area. If the high pressure side fuel filter 7 2 is disposed in the fuel inflow path 3 2 D, it is not limited by the foregoing, and a suitable high pressure side fuel filter Ί 2 can be selected. Next, a second embodiment of the fuel supply device of the present invention will be described with reference to Fig. 4 . Further, the fuel pump P and the fuel injection valve J are the same as those in the embodiment of Fig. 1, and the same components are denoted by the same reference numerals, and the description thereof will be omitted. The base body 80 includes a side flange portion 8 Ο A facing the left side and a horizontal flange 8 Ο B facing the horizontal direction, and a first screw hole 80 for screwing the fuel pump P is formed on the side flange portion 8 Ο A C, at the horizontal flange 8 Ο B, a mounting hole 80D for mounting the intake pipe and a second screw hole 8 Ο E for mounting the fuel injection valve J are formed. Further, an opening of the left fuel flow path 8 1 A forming the fuel flow path 8 1 is bored toward the left end surface 80F of the side flange 80A, and is formed to face the lower end surface 80G of the horizontal flange 8 Ο B. The opening of the fuel flow path 8 1 B in the vertical direction of the fuel flow path 8 1 . Thus, the longitudinal axis X - X of the left fuel flow path 8 1 A and the longitudinal axis Z - Z of the vertical direction fuel flow path 8 1 B intersect perpendicularly within the base body B. The fixed iron core 3 of the fuel pump P is inserted into the left fuel flow path 8 1 A. In this state, the mounting portion 19 A of the fuel pump P is threadedly engaged with the first screw hole 80 C by the screw 60. Thus, the fuel pump P is fixed to the side 24 326 \the main gear \93\93104896\93104896 (replacement)-1 1257973 square flange 80A of the base body B. On the other hand, the inflow pipe 3 2 C of the inflow joint 3 of the fuel injection valve J is inserted into the vertical direction fuel flow path 8 1 B, and in this state, the screw 6 2 is screwed to the second screw hole 8 by the clip 6 1 . In the Ο E, the fuel injection valve J is fixed to the horizontal flange 80B of the base body B. According to the above configuration, the longitudinal axis X - X of the fuel flow path 5 penetrating the fixed iron core 3 of the fuel pump P is disposed in the horizontal direction along the left fuel flow path 8 1 A, and is passed through the fuel injection valve. The longitudinal axis Z-Z of the fuel inflow path 3 2 D in the inflow pipe 32C of J is disposed in the vertical direction along the vertical direction fuel flow path 8 1 B, and the fuel discharge path 5 and the fuel inflow path 3 2 D pass the left fuel The flow path 8 1 A and the vertical direction fuel flow path 8 1 B are arranged in a cross. According to the above configuration, although the pulsating pressure generated in the pump by the driving of the fuel pump P acts on the left fuel flow path 8 1 A through the fuel discharge path 5, the pulsating pressure and the fuel flow in the cross direction are perpendicular. The side wall of the road 8 1 B collides and attenuates. On the other hand, although the pulsating pressure generated in the fuel injection valve J is caused to act in the vertical fuel flow path 8 1 B through the fuel inflow path 3 2 D by the fuel injection valve J to open and close the injection hole 38 A, the pulsation The pressure will collide with the side walls of the cross left fuel flow path 8 1 A to attenuate. Therefore, since the action of the pulsating pressure occurring in the mutual machine on the other machine parts can be reduced, the effect of maintaining the pump performance of the fuel pump P and the discharge performance of the fuel injection valve J can be obtained. A third embodiment of the present invention will now be described with reference to FIG. In addition, the same components as in Fig. 1 use the same component symbols, and the description of 25 326\total file\93\93104896\93104896 (replacement)-1 1257973 is omitted. 90 is a low pressure side fuel filter having the following structure. 9 1 is a bottomed cup-shaped filter case having a lower opening and including a fuel inflow path 9 2 on the side wall, and 13 3 is a filter cover that closes the lower opening of the filter case. A cylindrical portion 9 3 A extending in the vertical direction is provided at a central portion of the filter cover, and a flow path 9 3 D from the upper end to the lower end is bored in the tubular portion 913A. Further, a male thread 9 3 E is formed on the outer circumference of the tubular portion 9 3 A extending downward. Further, the outer peripheral portion of the filter cover 913 is riveted inwardly on the outer peripheral flange of the filter housing 91, and thus, the filter housing 9 1 and the filter cover 913 are hermetically formed. 9 4 is a filter body constituting a cylindrical shape, and the flat upper plate 9 4 A and the lower plate 9 4 B are connected by an annular filter paper 9 4 C, and the upper cylindrical portion 9 3 A is disposed inside the filter body 94 (filter paper 9) 4 C inside). Further, the filter body 94 is pressed against the filter cover 93 by a spring 9 5 which is contracted between the upper plate 94A and the bottom of the filter case 919, and is fixed. Further, the inflow joint 15 projecting above the fuel pump P has a flange 15A at the upper end, and the fuel inflow passage 16 penetrating the inflow joint 15 through the female thread 15B on the flange 15A The end face is open. Thus, the low-pressure side fuel filter 90 is screwed to the inflow joint 15 of the fuel pump P by threading the male thread 9 3 E of the tubular portion 933A into the female thread 15 5 B of the inflow joint 15 . Flange 1 5 A. Further, the fuel inflow path 9 2 of the low pressure side fuel filter 90 holds the fuel pipe 60 and is connected to the fuel tank T. Therefore, once the fuel pump P is driven, the fuel in the fuel tank T flows into the filter housing 9 1 through the fuel 26 326 \the main gear \93\93104896\93104896 (replacement)·1 1257973 tube 6 Ο, the fuel inflow path 9 2 , This fuel removes foreign matter from the filter paper 9 4 C of the filter body 94, and supplies clean fuel to the fuel inflow path 16 of the fuel pump port from the flow path 9 3 D opened in the filter body 94. According to the foregoing embodiment, since the low pressure side fuel filter 90 is disposed integrally with the fuel pump, the fuel pipe 69 can also connect the fuel inflow path 9 2 of the low pressure side fuel filter 90 to the fuel tank port, the fuel pipe. 6 9 is simple and can simplify the connection. By removing the base body Β from the intake pipe 60, the low-pressure side fuel filter 90 can be temporarily removed, and the maintainability of the filter can be improved. By directly arranging the low pressure side fuel filter 90 on the fuel pump port, it is possible to cool the fuel pump port by the fuel in the low pressure side fuel filter 90. The fuel pump cartridge of the present invention may be a positive displacement pump or a non-volumetric pump called an electric fuel pump that functions as a pump by energizing the electromagnetic coil. Alternatively, instead of the intake pipe 60, the base body may be attached to the throttle body 64. Moreover, the structure of the fuel injection width J is not limited to the embodiment, and the method of mounting the fuel injection valve J and the fuel pump cartridge on the base body is not limited to the embodiment. According to the fuel supply device of the present invention, the fuel in the fuel tank is boosted by the fuel pump, and the fuel injection valve is injected into the fuel supply device that supplies the boosted fuel to the internal combustion engine through the fuel injection valve. J and the fuel pump 一体 are integrally mounted on the base body, and at the same time, the fuel pump's fuel discharge path and the 27 326\total gear\93\93104896\93104896 (replacement)-1 1257973 fuel injection valve through the fuel inflow path The fuel flow paths in the base body are connected. A base body including the foregoing fuel injection valve and the fuel pump is mounted on the intake pipe, and since the injection hole of the fuel injection valve supported by the base body and the intake pipe opens into the intake pipe, if the fuel pump and the fuel injection valve are to be used When the fuel supply system component of the base body is mounted on the vehicle, the assemblability of the vehicle whose installation space is extremely limited, such as a two-wheeled vehicle, can be improved. Since the fuel pipe can also be connected to the fuel pump and the fuel tank, the design freedom of the fuel pipe is improved, and the pipe connection can be improved. Since the fuel that has been boosted from the fuel to the fuel injection valve is held in the fuel flow path formed in the base body, there is no need to particularly consider the pressure resistance of the fuel pipe, and the fuel pipe is directly exposed to the outside of the two-wheeled vehicle or the outboard. The fuel supply device of the present invention is particularly effective in machines, general machines, and the like. When the fuel pump is driven, the heat generated by the electromagnetic coil itself in the fuel pump is reduced by the base body, and since the heating of the fuel injection valve can be suppressed, the vapor generated in the fuel flowing in the fuel injection valve can be suppressed, and the fuel is sprayed from the fuel injection valve. The fuel can be supplied to the internal combustion engine in a stable and stable manner. Moreover, since the distance between the fuel pump and the intake pipe is equivalent to the thickness of the base body, it is possible to suppress the temperature rise of the fuel pump caused by the heat of the intake pipe, and while ensuring the stable discharge of the fuel pump, An inexpensive electromagnetic coil with low insulation is used. When an external force is applied to one of the fuel pump and the fuel injection valve projecting from the base body, even if the device supporting portion on the base body is partially deformed, the other device supporting portions are not deformed, so that the device is applied to the two directly exposed to the outside. 326\Total file\93\93104896\93104896 (replacement)-1 1257973 It is better on the wheeler. Since the fuel pump and the fuel injection valve are mounted on the same mounting member, that is, the base body, the fixing mechanism can be simplified. If the longitudinal axis of the fuel discharge path of the fuel pump, the longitudinal axis of the fuel inflow path of the fuel injection valve, and the longitudinal axis of the fuel flow path are arranged on the same straight line, the straightness of the fuel from the fuel pump to the fuel injection valve can be improved. In particular, the responsiveness at the time of starting the internal combustion engine is improved, and when the electromagnetic plunger pump or the like is used, the effect of lower discharge pressure is obtained. If the longitudinal axis of the fuel discharge path of the fuel pump and the longitudinal axis of the fuel inflow path of the fuel injection valve are arranged to cross each other through the longitudinal axis of the fuel flow path, the pulsation pressure caused by the pulsation of the fuel pump and the pulsation caused by the action of the fuel injection valve Since the pressure is respectively attenuated by the collision of the fuel flow path, the pump discharge performance of the fuel pump and the discharge performance of the fuel injection valve are stable, and can be favorably maintained. If a coupler connected to the electromagnetic coil disposed in the aforementioned fuel pump and a coupler connected to the electromagnetic coil disposed in the fuel injection valve are disposed in the same outer circumferential direction, the measurement type connector connected to the external power source can be improved The connection with the coupling of the fuel pump is disassembled and the connection between the measuring connector of the external power supply and the coupling of the fuel injection valve is disassembled, so it is preferable to use it in a two-wheeled vehicle with a narrow installation space. If a high-pressure side fuel filter is provided in the fuel flow path in the aforementioned base body, the piping surrounding the high-pressure side fuel filter is not required, and the housing surrounding the high-pressure side fuel filter is not required, and in addition, the high pressure is required. The filter and area selection of the side fuel filter is not limited, and the filter area suitable for 29 326\total file\93\93104896\93104896 (replacement)-1 1257973 can be set. If the low-pressure side fuel filter is integrally provided in the fuel inflow path of the fuel pump, since the fuel pipe can be connected only to the fuel inflow path and the fuel tank of the low-pressure side fuel filter, the operation of the fuel pipe is greatly simplified. At the same time, the maintenance of the low-pressure side fuel filter can be performed simultaneously by detaching the base body from the intake pipe. In addition, the fuel pump can be cooled by the fuel in the low-pressure side fuel filter to suppress the increase in fuel pump temperature. Further, if the base body is formed of a synthetic resin material, the effect of the heat generated by the electromagnetic coil of the fuel pump of the base body can be reduced, and it is difficult to transfer heat to the fuel injection valve, and the discharge accuracy from the fuel injection valve can be further improved. At the same time as the stability, when the intake pipe is heated, the heat of the intake pipe acts to reduce the base body, and it is difficult to transfer heat to the fuel pump, which can improve the accuracy and stability of the discharge from the fuel pump.
