於燃料管附近的燃料喷射閥之電連接器也會有附著燃料 虞。 本發明所成的燃料喷射裝置之燃料管為鑑於前述課 而所完成，其第1目的為提供，在引擎起動時，操作開 閥而將含有蒸汽之燃料朝外部排出時，可將要排出的燃 藉排出至所希望之一定位置，而可抑止：包含燃料喷射閥 圍的機器附著燃料，及使操作開關閥的操縱者附著燃料 及在燃料噴射閥的電連接器附著燃料者。 (解決問題之手段） 本發明的燃料噴射裝置之燃料管，為了達成前述目的 326\ 總橋\93\93118062\93118062(替換)-2 管 上 引 手 被 周 須 飛 置 之 題 關 料 周 6 1276740 在以燃料泵對燃料箱内的燃料昇壓，再藉由燃料 引擎喷射供給該被昇壓之燃料，如此的燃料噴射 其第1特徵為， 在内部具有燃料流路，被固定配置在固定元件 為，在燃料流路的重力方向中之下方形成有可插

側開口部開口在燃料箱内，如此為其第2特徵。 又，本發明除了前述第1特徵外，使前述排出 側開口部接續在壓力調節器的回程燃料通路上， 第3特徵。 又，本發明除了前述第1特徵外，前述常閉型 為藉朝向閥座以第1彈簧被押壓之閥體，及，在 向側以第2彈簧被押壓，同時以具有可遮斷燃料 和大氣之密封元件的操作桿而被分離形成，藉使 拒第1彈簧、第2彈簧的彈簧力押壓而動作閥體 放，如此為第4特徵。

又，本發明除了前述第5特徵外，在引擎的電池馬達驅 動之間通電使前述電磁裝置，藉由可動鐵心使操作桿動作 之閥體開放，如此為第6特徵。 又，本發明除了前述第4特徵外，在前述操作桿之非操 作狀態下，在操作桿和閥體之間形成保持有間隙，如此為 其第7特徵。 又，本發明除了前述第4特徵外，在前述操作桿之非操 作狀態，使操作桿之押壓部外側端位於比燃料管的外側端 之更内方，如此為其第8特徵。 (發明效果） 根據本發明之第1特徵，例如在引擎之熱再起動時，以 電氣驅動燃料泵，同時，手動操作常閉型之開關閥而開放 閥座，而連通燃料流入室和燃料排出室。根據此一構成， 停滯在燃料導入管及燃料流入室内之蒸汽會被昇壓而和燃 料共同流入燃料排出室内，再藉由排出孔、排出管將含有 蒸汽之燃料排出至所希望之一定位置。 因此，自燃料喷射閥對引擎可連續且安定地供給未含有 蒸汽之燃料，而可實施引擎之良好的熱再起動。又，由於 含有前述蒸汽之燃料為藉由排出管排出至自燃料管離開之 所希望的位置，因此，在燃料管及燃料管周圍的機器不會 附著有燃料及異物，而可長期使燃料管的周圍維持清潔， 8 326\總檔\93\93118062\93118062(替換)-2 著燃料所生之橡膠、 不會對安裝在燃料管 可長期維持電氣接續 蒸汽之燃料排出至自 關閥之操縱者附著燃 駕駛者跨越過燃料 由確認自排出管排出 作。 明之第2特徵，開關 料則被流回至燃料箱 耗燃料，而可抑止燃 散至大氣中並可防止 明之第3特徵，開關 燃料則會流入壓力調 料箱内。根據該一構 由於是利用壓力調節 管長度縮短，同時， 開口，而可使用原來 明之第4特徵，開關 在操作桿之非操作狀 力在閥關閉方向側， 上，藉此可保持燃料 面，操作桿抗拒第2 1276740 同時，可抑止附 及劣化。特別是 接器附著燃料而 藉排出管將含有 而可抑止操作開 車，其最適合於 形。進一步，藉 確認燃料泵之動 又，根據本發 管含有蒸汽的燃 因不會無謂地消 時，燃料不會蒸 較佳。 又，根據本發 管之含有蒸汽的 内，並再流回燃 流回燃料箱時， 因此，可使排出 的回程用之燃料 又，根據本發 分離形成，因此 2彈簧被賦加彈 押壓保持在閥座 之遮斷。另一方 樹脂等的零件之澎潤 的燃料噴射閥之電連 之安定性。進一步， 燃料管離開之位置， 料，特別是如二輪機 管的近旁而乘車之情 之前述燃料其也可作 闊被開放而流下排出 内。根據此一構成， 料經濟性之惡化，同 對大氣之污染，因此 閥被開放而流下排出 節器之回程燃料通路 成，排出管内的燃料 器的回程燃料通路， 在燃料箱不必穿設新 的燃料箱。 閥為藉操作桿和閥體 態下，操作桿為以第 閥體以第1彈簧而被 流入室和燃料排出室 彈簧之彈簧力而被押 326V總檔\93\93118062\93118062(替換)-2 9 1276740 壓在開放方向側時，操作桿可更使閥體抗拒第1彈簧之彈 簧力而自閥座離開並使閥座開放，藉此而使燃料流入室和 燃料排出室連通，再藉由閥座、燃料排出室、排出孔而自 排出管排出停滯在燃料流入室内之蒸汽。又，由於操作桿 為具有可遮斷燃料排出室和大氣之密封元件，因此，流入 燃料排出室内的燃料則不會藉由操作桿之周圍而漏出至大 氣側。根據以上構成，即使操作桿之押壓方向的中心和閥 體之開閉方向的中心被偏心配置時，對閥體的閥座也可經 常維持良好的閉塞性。又，朝向閥座押壓閥體之第1彈簧 的彈簧力，可和押壓操作桿之第2彈簧的彈簧力無關地選 擇設定為比較弱的彈簧力，藉此而可減低閥體對闊座之摩 擦消耗，並可長期維持安定的閥閉塞性。 又，根據本發明之第5特徵，在引擎起動時，藉對電磁 裝置的電磁線圈通電而可使可動鐵心動作，藉該可動鐵心 之動作可移動操作桿而自動地開放閥座，且自動地自排出 管排出含有蒸汽之燃料。另一方面，在引擎起動後，對電 磁線圈斷電時則可自動的使閥座再度保持為閉塞狀態。根 據以上之構成，特別是在二輪機車中，駕駛者在騎上二輪 機車之狀態下可作前述電氣切換而大大地提高操作性。 又，根據本發明之第6特徵，在引擎起動時驅動電池馬 達之間，電磁裝置的電磁線圈被通電，而可自動地開放閥 座且自動地由排出管排出含有蒸汽之燃料。另一方面，停 止電池馬達的驅動時，對電磁線圈斷電而再保持閥座之閉 塞狀態。根據以上構成，由於可和電池馬達同時實施閥體 10 326\ 總檔\93\93118062\93118062(替換)-2 1276740 之動作，因此引擎每次起動操作時可確實排出蒸汽。又， 駕駛者只要作電池馬達之驅動操縱即可，不必特別再操作 閥體，如此而可提高其操作性。 進一步，根據本發明之第7特徵，在操作桿之非操作狀 態下，在操作桿和閥體之間被形成有間隙。根據該構成， 在操作桿之非操作狀態下，由於閥體和操作桿被保持於非 接觸狀態，因此，閥體以第1彈簧可確實押壓閥座，而可 保持闊座具有良好的閉塞性。又，在引擎的運轉中，即使 操作桿有微振動時，操作桿也會押壓閥體而不會開放，如 此則可安定地保持閥座之閉塞狀態。又，操作桿和閥體的 對向部則不會有衝突之摩耗。 又，根據本發明之第8特徵，在操作桿之非操作狀態下， 操作桿的押壓部外側端被配置於比燃料管的外側端更内方 的位置。根據該構成，特別是在乘騎二輪機車之駕駛者不 慎接觸到操作桿時也不會押壓到操作桿。又，在行駛中， 操作桿則不會接觸到外物，操作桿不會有破損或彎曲，並 可長期安定地維持操作桿之操作性。 【實施方式】 以下藉圖1、圖2說明本發明所成的燃料喷射裝置中之 燃料管之一實施例。 圖1為本發明之燃料管被安裝在進氣管之燃料喷射裝置 的全體構成圖，圖2為燃料管之重要部份擴大縱剖面圖。 首先說明燃料噴射裝置之全體構成。 10a為在内部穿設貫通有進氣通路11之節流體，進氣通 326\總檔\93\93118062\93118062(替換)-2 11 1276740 路1 1為藉安裝在可迴轉自如地被支持於節流體1 0 a的節流 閥軸1 2之蝶型的節流閥1 3而被控制開閉。又，節流體1 0 a 的進氣通路1 1之上流側11 a為被接續至空氣濾清器A，下 流側1 1 b為藉由進氣管2 0被接續至引擎E。T為在内部貯 留有燃料之燃料箱，燃料箱T内之燃料為藉由燃料進入路 Pa而被吸入燃料泵P内而昇壓，該被昇壓之燃料為藉由燃 料吐出路P b而被供給至燃料導入管3 0。又，R為將由燃料 泵P所供給之在燃料導入管3 0内流動的燃料壓力調壓為一 定燃料壓力之壓力調節器，其被接續配置至燃料導入管 3 0，同時，可自壓力調節器R排出多餘燃料之回程燃料通 路3 1被接續至燃料箱T内。 因此，藉空氣濾清器A被除去異物之清淨空氣會流入節 流體1 0 a之進氣通路1 1，其流入量為由駕駛者以操作節流 閥1 3而被控制，該被控制之空氣為藉由進氣管2 0被供給 至引擎E。另一方面，在燃料箱T内之燃料為，以燃料泵P 被昇壓後被供給至燃料導入管3 0内，另一方面在燃料導入 管3 0流動之燃料為藉壓力調節器R被調壓至一定燃料壓 力，壓力調節器R的多餘燃料則藉由回程通路3 1而被送回 至燃料箱T内。 燃料管 1 被穿設有在内部於上下方向貫通之燃料流路 2，燃料流路2之下方具有喷射閥支持孔2a朝下方開口， 在燃料流路2之上方，螺著有被穿設導引孔3 a之操作桿導 引塞3。燃料管1之上方的外側端1 a為藉操作桿導引塞3 之上端3b所形成。 12 326\總檔\93\93118062\93118062(替換)-2 1276740 又，在燃料流路2之大致中間部形成有閥座4，閥座4 為使燃料流路2區分為朝向上方之燃料排出室5和朝向下 方之燃料流入室6。前述喷射閥支持孔2 a在燃料流入室6 開口。7為對向配置於前述閥座之閥體，閥體7為藉第1 彈簧S1被押壓至閥座4而使閥座4閉塞。前述閥體7為具 有，被配置在燃料流入室6内且對向配置於閥座4，同時， 藉閥體7朝向燃料排出室5内在上方突出之閥桿7 a，前述 第1彈簧S1之下端Sla被繫止於形成在閥座4内方之繫止 段部4 a，上端S 1 b則被繫止在閥桿7 a之突緣部7 b。 8為配置在燃料排出室5内之操作桿，操作桿8的軸部 8 a為在軸方向可移動自如地被支持在操作桿導引塞3之導 引孔3 a上，操作桿8之下端8 b對向配置在閥桿7 a之上端。 前述操作桿8為藉第2彈簧S 2被押壓至閥關閉方向側（圖 之上方），第2彈簧S2之下端S2a為被繫止至燃料排出室 5之繫止段部5 a，上端S 2 b為被繫止至操作桿8之繫止段 部8 c之下面。根據以上構成，操作桿8為藉第2彈箐S 2 被押壓至閥關閉方向側（圖之上方），其上方向移動為藉操 作桿8的繫止段部8 c之上面擋接至操作桿導引塞3的繫止 段部3 c之定位而被限制。該操作桿8之上方停止位置為未 對操作桿8加以任何外力之非操作狀態，在該狀態下，操 作桿8的押壓部外側端8 d (換言之圖中操作桿8之上端）為 位於比燃料管1的外側端1 a之更内方。（換言之，操作桿 8之上端為被配置於比操作桿導引塞 3的上端 3b之更下 方）。又，在操作桿8之非操作狀態中，操作桿8之下端 13 326V總檔\93\93118062\93118062(替換)-2 1276740 8 b和閥體7的閥桿7 a之上端為被對向配置，同時，被配 置成在其對向間形成間隙c。 又，9為配置在操作桿導引塞3的内徑部和操作桿8的 軸部 8 a之外周部之間的端頭密封（1 i p s e a 1 )等之密封元 件，L為配置在操作桿導引塞3的外周和燃料排出室5之 間的密封用0環。根據以上構成，藉由操作桿導引塞3的 導件3a，燃料排出室5内的燃料則不會漏出至外部，藉由 操作桿導引塞3的外周，燃料排出室5内的燃料則不會漏 出至外部。 又，在燃料排出室5穿設有排出孔1 0之開口 ，在燃料 流入室6有燃料導入管30之開口部30a開口。 再度簡單整理以上所說明的燃料管1如下。 燃料管1為在上下方向形成燃料流路2，在其中間部形 成有閥座4，燃料流路2為藉閥座4在其重力方向的下方 被區分形成為燃料流入室 6，在其上方被區分形成為燃料 排出室 5。又，臨近閥座 4配置有閥體 7，同時，闊體 7 藉第1彈簧S1朝向閥座4被押壓支持。在燃料排出室5 内配置有操作桿8。操作桿8之下端8 b被配置於臨近閥桿 7 a的上端，同時，操作桿8的押壓部外側端8 d被配置成 臨近燃料管 1之外側端 1 a外方開口 ，進一步，操作桿 8 為藉第2彈簧S 2在閥關閉方向側被賦予勢能。又，在燃料 流入室6之下端，朝向下方有喷射閥支持孔2 a開口，同時， 有燃料導入管3 0的開口部3 0 a之開口。進一步，在燃料排 出室5有排出孔1 0之開口。 14 326\總檔\93\93118062\93118062(替換)-2 1276740 又，前述燃料管為如下被固定在進氣管 2 0同時實 料配管。 在燃料管1的噴射閥支持孔 2 a内插入有燃料噴射 的流入側端部 J a，根據此構成，在流入側端部 J a開 燃料流入孔被配置成在燃料流入孔6内之重力方向於 開口 。 其次，在插入燃料喷射閥J之燃料管1的外周之溝 内安裝有平板狀之安裝板3 2，同時，燃料喷射閥J之 部J a被插入穿設在進氣管2 0的導引孔2 0 a内，在該# 安裝板3 2被配置於突出在進氣管2 0的外周所形成之 元件2 0 b上，再藉螺釘等的繫緊元件3 3而朝固定元片 螺_固定。 根據以上構成，燃料管1為藉由安裝板3 2被固定 氣管2 0上，燃料噴射閥J為被燃料管1和進氣管2 0 持。另一方面，燃料泵P之燃料吐出路Pb為藉由燃料 管3 0的開口部3 0 a被接續至燃料管1的燃料流入室 在燃料管1之排出孔1 0接續至排出管3 4，該排出管 大氣側之開口部3 4 a為在適當的部位開口。 其次說明其作用。 燃料導入管 3 0在燃料管1内的燃料被大大地加熱 態而起動引擎時，例如以熱再起動說明時，駕驶者首 施操作起動，藉此，電動式的燃料泵 P、點火塞等的 變成通電狀態，燃料泵P被驅動而吸入燃料箱T内的 並昇壓，該被昇壓的燃料被供給至燃料導入管3 0，燃

閥體7往下方押壓而使閥座4保持開放。圖3表示該 7之閥座的開放狀態。當該閥座4被開放時，被昇壓 在燃料導入管3 0及在燃料管1的燃料流入室6内之燃 藉由閥座4、燃料排出室5、排出孔1 0、排出管3 4、 部3 4 a —口氣地朝外部而被排出，而比燃料比重為輕 汽也和前述燃料流動一口氣地由排出管 3 4的開口部 朝外部4非出，如此可抽出燃料導入管3 0、燃料流入室 之蒸汽。因此，駕駛者再度操作起動引擎時，藉燃料 被昇壓而只將未存在有蒸汽之所希望的燃料連續地自 喷射閥J對進氣管2 0内喷射供給，其可確實地實施引 熱再起動。又，在引擎起動後，由於可將蒸汽積極的 外部，其可連續的對引擎供給正確的燃料，因此，在 以後可得到安定的行駛性能。 又，在長期放置引擎（長期引擎未使用）之狀態時， 動操作可和熱再起動時相同。根據以上構成，由於長 置而劣化的燃料可藉由排出管 3 4的開口部 3 4 a被排 部，其可自燃料噴射閥J朝向引擎E供給新的燃料，g 即使長期放置後亦可確實使引擎起動。 在此處本發明的燃料管1之第1特徵為，燃料管1 燃料流路2為藉閥座4而被分離形成為密封的燃料排 5，排出孔1 0在燃料排出室5内開口 ，同時，排出 326\總檔 \93\93118062\93118062(替換)-2 壓力 簧 S2 力使 閥體 保持 料會 開口 的蒸 34a 6内 泵

可解消燃料飛散在燃料管1的周圍而使燃料管1及其周圍 污染，同時，可抑止燃料附著在配置於周圍之橡膠、樹脂 等的零件而發生之膨潤或劣化。又，由於燃料不會朝向接 近燃料管1所配置之燃料喷射閥J的電連接器飛散，因此 可在長期維持良好的電連接器。進一步，由於被形成為密 閉的燃料排出室5，自燃料排出室5朝外部之燃料可藉由 排出管3 4僅被排出至離開的位置，因此，對操縱操作桿之 駕駛者其不會附著燃料，特別是對於二輪機車很適合。又， 當引擎起動操作，同時，藉確認閥座且自排出管34流出的 燃料則可確認燃料泵P是否正常驅動，因此可非常容易確 認燃料泵之驅動。 又，藉使排出管3 4之開口部3 4 a開口在燃料箱T内時， 由於可將自排出管3 4所排出之燃料再送回至燃料箱T内， 因此所有的燃料不會飛散至周圍而可有效地使用燃料，進 一步，藉燃料的蒸發而可防止對大氣污染。 又，藉使排出管 3 4之開口部 3 4 a開口在壓力調節器R 之回程燃料通路3 1内時，則不必在燃料箱T設置新的燃料 開口部，而可使用先前原有的燃料箱 T。又，其可使排出 管3 4的長度縮短相當於回程燃料通路3 1之長度的部份， 17 326\總檔\93\93118062\93118062(替換)-2 1276740 而可提高排出管3 4之配管的佈置性。 又，當使可開閉閥座4之常閉型的開關閥，藉分離形成 為臨近閥座4所配置之閥體7，及，可賦予閥體7開放力 之操作桿8時，即使閥體7的押壓中心和操作桿8的押壓 中心被偏離而偏心配置時，對閥體7的閥座4也可時常維 持良好的閉塞性。例如操作桿8被傾斜配置時也不會對閥 體7有不良影響。又，當使閥體7朝向閥座4賦予勢能之 第1彈簧S 1和使操作桿8朝向閥座關閉方向側賦予勢能之 第2彈簧S 2各別分離配置時，第1彈簧S1的彈簧力只要 具備閥體7可閉塞閥座4所需之彈簀力，即可使闊體7具 有適當之彈簧力押壓閥座4，並可減低閥體7、閥座4之摩 耗。又，藉在操作桿8設置密封元件9則可氣密地保持燃 料排出室5。 又，在操作桿8之非操作狀態下，在操作桿8的下端8 b 和閥體7的閥桿7 a的上端之間形成間隙c時，即使操作桿 8及閥體7的長度方向之尺寸精確度不佳而操作桿8擋接 闊體7時，閥體7也不會不慎使閥座4開放。又，在引擎 運轉中，即使操作桿8在長度方向稍微振動時，操作桿8 擋接閥體4而使開閉反覆時也不會發生聲音而和闊體4之 接觸部也不會摩擦消耗。 進一步，使操作桿 8的押壓部外側端 8d配置於比操作 桿導引塞3的上端3 b更内方時（換言之，使操作桿8的押 壓部外側端8d配置在比燃料管1的外側端之更内方），駕 駛者則不會不慎接觸到操作桿8而押壓到操作桿8。又， 18 326\總檔\93\93118062\93118062(替換)-2 1276740 行駛中操作桿8不會接觸到其他元件而使其彎曲或破 而可良好地保護操作桿8。此對燃料管1配置在直接 大氣之二輪機車中特別有效用者。 其次藉圖4說明本發明之燃料管的其他實施例。 和圖2同一構造之部份為使用同一符號而省略其說 D為可電氣操縱操作桿8之電磁裝置，其為藉以下 成。

(Patent Document 1) Japanese Patent Application No. 2 0 0 3 - 1 3 6 7 2 0 [Problem to be Solved by the Invention] According to the fuel pipe of the prior fuel injection device, when the engine is started, the operation is started. When the valve is opened and the open air is opened, the fuel containing steam is discharged to the periphery of the fuel pipe and scattered. In this way, the fuel adheres to the machine surrounding the fuel pipe, and further, foreign matter tends to adhere to the fuel, and the frequency of maintenance of the machine must be increased. Moreover, especially for the two-wheeled vehicle, the scattered fuel may adhere to the rider's shackles, so it is not good. Further, the electrical connector of the fuel injection valve disposed near the fuel pipe may also have a fuel 附着 attached thereto. The fuel pipe of the fuel injection device according to the present invention has been completed in view of the above-described lessons, and a first object thereof is to provide a fuel that can be discharged when the valve is opened and the fuel containing steam is discharged to the outside when the engine is started. By discharging to a desired position, it is possible to suppress the machine-attached fuel including the fuel injection valve, and the operator who operates the on-off valve to attach the fuel and the fuel to the fuel injection valve. (Means for Solving the Problem) The fuel pipe of the fuel injection device of the present invention, in order to achieve the aforementioned purpose 326\total bridge\93\93118062\93118062 (replacement)-2 pipe-handed by Zhou Xingfei, the title of the material week 6 1276740 The fuel pump boosts the fuel in the fuel tank, and the boosted fuel is injected by the fuel engine. The first feature of the fuel injection is that the fuel flow path is internally provided and fixedly disposed on the fixed component. The injection valve support hole of the inflow side end portion of the insertable injection valve is formed below the gravity direction of the fuel flow path, and the fuel flow path of the support hole at the upper position is supported by the normally closed type switch. a closed fuel inflow chamber; and a closed fuel injector; the fuel inflow chamber opening has an opening of the fuel introduction pipe, and the injection valve support hole is inserted into the inflow side end surface of the fuel injection valve, so that the discharge hole is opened in the foregoing At the same time, the fuel discharge chamber is connected to the discharge pipe and the opening of the outlet side of the discharge pipe is opened. Further, in addition to the first feature described above, the present invention has such a second feature that the discharge-side opening is opened in the fuel tank. Further, in addition to the first feature described above, the present invention provides the third feature in that the discharge-side opening portion is connected to the return fuel passage of the pressure regulator. Further, in addition to the first feature of the present invention, the normally closed type is a valve body that is pressed by the first spring toward the valve seat, and is biased by the second spring on the side, and is slidable at the same time. The fuel and the sealing member of the atmospheric sealing element are separated, and the valve body is actuated by pressing the spring force of the first spring and the second spring, which is the fourth feature. 326\总档\93\93118062\93118062 (replacement)-2 In the injection valve pair device, the fuel pipe inlet support combustion ratio injection valve is distinguished from the chamber; at the time, by the other side, the discharge hole is in the desired pipe The atmosphere of the atmospheric tube is such that its on-off valve is closed. The discharge chamber is operated. The operating lever is made to open the valve seat. 7 1276740 Further, in addition to the aforementioned fourth feature, the present invention is electromagnetically formed by an electromagnetic coil, a movable iron core, and a fixed iron core. The device D operates the aforementioned operating lever, which is the fifth feature. Further, in addition to the above-described fifth feature, the present invention is characterized in that the electromagnetic device is energized between the battery motors of the engine to open the valve body in which the operating lever is operated by the movable iron core. Further, in addition to the above-described fourth feature, the present invention has a seventh feature in which a gap is formed between the operating lever and the valve body in the non-operating state of the operating lever. Further, in addition to the above-described fourth feature, the present invention is such that the outer end of the pressing portion of the operating lever is located inward of the outer end of the fuel pipe in the non-operating state of the operating lever, and thus the eighth feature. According to the first aspect of the present invention, for example, when the engine is restarted, the fuel pump is electrically driven, and the normally closed type on-off valve is manually operated to open the valve seat to communicate the fuel inflow chamber and the fuel discharge. room. According to this configuration, the steam stagnated in the fuel introduction pipe and the fuel inflow chamber is pressurized and flows into the fuel discharge chamber together with the fuel, and the fuel containing the steam is discharged to a desired position through the discharge hole and the discharge pipe. Therefore, the fuel injection valve can continuously and stably supply the fuel containing no steam to the engine, and a good thermal restart of the engine can be performed. Further, since the fuel containing the steam is discharged to a desired position from the fuel pipe by the discharge pipe, fuel and foreign matter are not adhered to the machine around the fuel pipe and the fuel pipe, and the fuel pipe can be used for a long time. The surrounding area is kept clean, 8 326\main file\93\93118062\93118062 (replacement)-2 The rubber produced by the fuel will not be discharged to the self-closing valve for the fuel that can be installed in the fuel pipe for long-term maintenance of the electrical connection steam. The adhering fuel rider crosses the fuel and is confirmed to be discharged from the discharge pipe. According to the second feature of the invention, the switch material is returned to the fuel tank to consume fuel, which suppresses the emission to the atmosphere and prevents the third characteristic, and the switching fuel flows into the pressure regulating tank. According to this configuration, since the length of the pressure regulating tube is shortened and the opening is used, the fourth characteristic of the original can be used, and the non-operating force of the switch on the operating lever is on the valve closing direction side, thereby maintaining the fuel surface. The lever resists the 2,127,740, while suppressing the deterioration. In particular, the connector is attached to the fuel and is contained by the discharge pipe to prevent the operation of the vehicle, which is most suitable for the shape. Further, by confirming the movement of the fuel pump, the fuel containing steam according to the present invention does not unnecessarily disappear, and the fuel is not steamed. Moreover, according to the inside of the hair tube containing the steam, and then flowing back to the fuel tank, the fuel for the returned return can be separated and formed according to the present invention, so that the spring is biased by the spring. Keep it blocked at the valve seat. The stability of the electrical connection of the fuel injection valve of the other component such as resin. Further, the fuel pipe leaves the position, and the fuel, in particular, the fuel as it is in the vicinity of the second turbine, can also be opened and discharged. According to this configuration, the deterioration of the economy of the material is the same as the pollution of the atmosphere, so that the valve is opened and the return fuel passage of the discharge damper is formed, and the return fuel passage of the fuel injector in the discharge pipe does not have to be worn in the fuel tank. Fuel tank. The valve is operated by the operating lever and the valve body, and the operating lever is biased by the spring force of the first valve and the fuel discharge chamber spring by the first spring. 326V total gear\93\93118062\93118062 (replacement)-2 9 1276740 When the pressure is pressed on the open side, the operating lever can make the valve body resist the spring force of the first spring and leave the valve seat and open the valve seat, thereby connecting the fuel inflow chamber and the fuel discharge chamber, and then The valve seat, the fuel discharge chamber, and the discharge port discharge steam that has stagnated in the fuel from the discharge pipe. Further, since the operating lever has a sealing member that can block the fuel discharge chamber and the atmosphere, the fuel flowing into the fuel discharge chamber does not leak to the atmosphere side by the periphery of the operating lever. According to the above configuration, even if the center of the pressing direction of the operating lever and the center of the opening and closing direction of the valve body are eccentrically arranged, the valve seat of the valve body can be maintained in a good occlusive property. Further, the spring force of the first spring that presses the valve body toward the valve seat can be selected to be a relatively weak spring force regardless of the spring force of the second spring of the pressing lever, thereby reducing the valve body width The friction of the seat is consumed, and the stable valve occlusion property can be maintained for a long time. According to a fifth aspect of the present invention, the movable iron core can be operated by energizing the electromagnetic coil of the electromagnetic device when the engine is started, and the movable iron can be moved to automatically open the valve seat by the action of the movable iron core, and automatically The fuel containing steam is discharged from the discharge pipe. On the other hand, after the engine is started, the valve seat can be automatically kept in the closed state when the electromagnetic coil is de-energized. According to the above configuration, particularly in the two-wheeled vehicle, the driver can perform the above-described electric switching while riding the two-wheeled locomotive, and the operability is greatly improved. Further, according to the sixth feature of the present invention, when the battery is driven at the time of starting the engine, the electromagnetic coil of the electromagnetic device is energized, and the valve seat can be automatically opened and the fuel containing steam can be automatically discharged from the discharge pipe. On the other hand, when the driving of the battery motor is stopped, the electromagnetic coil is de-energized and the valve seat is kept closed. According to the above configuration, since the operation of the valve body 10 326\the main gear \93\93118062\93118062 (replacement)-2 1276740 can be performed simultaneously with the battery motor, the steam can be surely discharged every time the engine is started. Further, the driver can operate the battery motor as long as it does not need to operate the valve body in particular, thereby improving the operability. Further, according to the seventh feature of the present invention, in the non-operating state of the operating lever, a gap is formed between the operating lever and the valve body. According to this configuration, since the valve body and the operating lever are held in a non-contact state in the non-operating state of the operating lever, the valve body can positively press the valve seat with the first spring, and the wide seat can be kept well occluded. Sex. Further, during the operation of the engine, even if the operating lever is slightly vibrated, the operating lever presses the valve body without opening, so that the valve seat can be stably closed. Moreover, there is no conflicting friction between the operating lever and the opposing portion of the valve body. According to the eighth aspect of the present invention, in the non-operating state of the operating lever, the outer end of the pressing portion of the operating lever is disposed at a position further inside than the outer end of the fuel pipe. According to this configuration, particularly when the driver riding the two-wheeled vehicle inadvertently contacts the operating lever, it is not pressed to the operating lever. Further, during running, the operating lever does not come into contact with foreign objects, the operating lever is not damaged or bent, and the operability of the operating lever can be maintained for a long period of time.

Start again. Further, after the engine is started, since the steam can be actively externally supplied, it can continuously supply the correct fuel to the engine, so that stable running performance can be obtained later. Also, when the engine is placed for a long period of time (the engine is not used for a long time), the operation can be the same as when the hot restart is performed. According to the above configuration, the fuel deteriorated by the long position can be discharged from the opening portion 34a of the discharge pipe 34, and the new fuel can be supplied from the fuel injection valve J toward the engine E, even after long-term placement. It does make the engine start. Here, the first feature of the fuel pipe 1 of the present invention is that the fuel pipe 1 is in a fuel line 5 which is separated from the valve seat 4 by a valve seat 4, and the discharge port 10 is opened in the fuel discharge chamber 5, At the same time, discharge 326\total file\93\93118062\93118062 (replace)-2 pressure spring S2 force to keep the valve body open to the steam 34a 6 pump P fuel engine's discharge start its release time outside, this inside The outlet opening 10 16 1276740 is connected to the discharge pipe 34, and the opening portion 34a of the discharge pipe 34 is opened at a desired position. According to this configuration, when the operation lever 8 operates the valve body 7 to open the valve seat 4, the fuel containing steam in the fuel introduction pipe 30 and the fuel inflow chamber 6 can be discharged through the opening portion 34a of the discharge pipe 34. Except for the proper place where the fuel pipe 1 is separated, no fuel is leaked from the periphery of the operating rod 8, which can dissipate the fuel from scattering around the fuel pipe 1 to contaminate the fuel pipe 1 and its surroundings, and at the same time, inhibit fuel adhesion. Swelling or deterioration caused by components such as rubber or resin disposed around the periphery. Further, since the fuel does not scatter toward the electrical connector of the fuel injection valve J disposed adjacent to the fuel pipe 1, a good electrical connector can be maintained for a long period of time. Further, since it is formed as a sealed fuel discharge chamber 5, the fuel from the fuel discharge chamber 5 to the outside can be discharged only to the exit position by the discharge pipe 34, and therefore, the driver who operates the operation lever does not adhere to it. Fuel, especially for two-wheelers, is suitable. Further, when the engine is started up, at the same time, by confirming the valve seat and the fuel flowing out from the discharge pipe 34, it is confirmed whether or not the fuel pump P is normally driven, so that the driving of the fuel pump can be easily confirmed. Further, when the opening portion 34a of the discharge pipe 34 is opened in the fuel tank T, since the fuel discharged from the discharge pipe 34 can be returned to the fuel tank T, all the fuel does not fly to The fuel can be used effectively around, and further, the evaporation of the fuel can prevent the pollution of the atmosphere. Further, when the opening portion 34a of the discharge pipe 34 is opened in the return fuel passage 31 of the pressure regulator R, it is not necessary to provide a new fuel opening portion in the fuel tank T, and the previously used fuel can be used. Box T. Moreover, it is possible to shorten the length of the discharge pipe 34 by a portion corresponding to the length of the return fuel passage 31, 17 326\total gear\93\93118062\93118062 (replacement)-2 1276740 to improve the discharge pipe 34 The layout of the piping. Further, when the normally-closed on-off valve of the openable and closable valve seat 4 is separated into the valve body 7 disposed adjacent to the valve seat 4, and the operating lever 8 that can open the force to the valve body 7, even the valve body When the pressing center of 7 and the pressing center of the operating lever 8 are deviated and arranged eccentrically, the valve seat 4 of the valve body 7 can always maintain good occlusion. For example, when the operating lever 8 is disposed obliquely, it does not adversely affect the valve body 7. Further, when the first spring S1 that gives the potential to the valve body 4 toward the valve seat 4 and the second spring S2 that gives the potential energy to the valve seat closing direction side are separately disposed, the spring of the first spring S1 As long as the force of the valve body 7 can block the valve seat 4, the wide body 7 has a suitable spring force to press the valve seat 4, and the wear of the valve body 7 and the valve seat 4 can be reduced. Further, by providing the sealing member 9 on the operating lever 8, the fuel discharge chamber 5 can be hermetically held. Further, in the non-operating state of the operating lever 8, when the gap c is formed between the lower end 8b of the operating lever 8 and the upper end of the valve stem 7a of the valve body 7, even the longitudinal direction of the operating lever 8 and the valve body 7 When the dimensional accuracy is not good and the operating lever 8 blocks the wide body 7, the valve body 7 does not inadvertently open the valve seat 4. Further, even if the operating lever 8 slightly vibrates in the longitudinal direction during the operation of the engine, the operating lever 8 blocks the valve body 4 so that no sound is generated when the opening and closing is repeated, and the contact portion of the wide body 4 is not rubbed and consumed. Further, when the pressing portion outer end 8d of the operating lever 8 is disposed inward of the upper end 3b of the lever guiding plug 3 (in other words, the pressing portion outer end 8d of the operating lever 8 is disposed in the specific fuel pipe 1) The inner side of the outer end), the driver does not inadvertently touch the operating lever 8 and presses it to the operating lever 8. Also, 18 326\total file\93\93118062\93118062 (replacement)-2 1276740 The operating lever 8 does not come into contact with other components while driving, and is bent or broken to protect the operating lever 8 well. This pair of fuel tubes 1 is particularly effective for use in a two-turbine vehicle in direct atmosphere. Next, another embodiment of the fuel pipe of the present invention will be described with reference to FIG. The same components as those in Fig. 2 are denoted by the same reference numerals, and the electromagnetic device in which D is electrically operable to operate the operating lever 8 is omitted. 40 has a cylindrical portion 40a at the center portion, and has a flange portion 40b extending on the lower side of the side of the cylindrical portion 40a, and has a side extending flange portion 40c above the square portion thereof, Winding bobbin. The bobbin is formed of a synthetic resin material having an insulating material, and at the same time, the electromagnetic coil 40 d is wound around the outer circumference of the portion 40 a. 4 1 is a lower pole piece 4 1 a disposed under the lower flange portion 40 b of the winding pipe 40; and a fixed core 41 b inserted in the cylindrical portion 40 a; thus formed The lower pole is formed by a magnetic material. Further, the lower magnetic pole 41 penetrates the insertion hole 4 1 c in the vertical direction from the upper surface of the fixed pole 4 1 b toward the lower surface of the lower pole piece 4 1 a. 4 2 is an upper pole piece disposed on the upper flange portion of the bobbin 40, and on the other hand, is disposed movably in the cylindrical portion of the bobbin 40 and is fixed to the fixed core 4 1 b The movable core 4 3 is formed by a magnetic material. 4 4 is an outer casing formed by a magnetic material disposed around the outer circumference of the coil 40 d, and the lower magnetic pole piece 4 1 a and the upper magnetic pole piece 4 2 are magnetically coupled, and when the coil 40 d is energized, A magnetic circuit is formed by the upper magnetic pole piece 4, the movable iron core 4 3, the iron core 4 1 b, the lower magnetic pole piece 4 1 a, and the outer casing 4 4 . 326\Total file\93\93118062\93118062 (replacement) - 2 damage, exposed. Under the shape of the side f 40 cylindrical bobbin into the matching side of the core through the 40c 40a core electromagnetic housing electromagnetically fixed again, 19 1276740 in this embodiment, the lower end of the outer casing 4 4 toward the operating rod guide plug 3 3d The caulking is performed, and the upper end is caulked toward the member 45 disposed on the upper pole piece 42. According to the above configuration, the operation lever guide plug 3 is screwed to the upper side of the fuel flow path 2 of the fuel member 1, and the electromagnetic device D is described above the fuel pipe 1. Therefore, in the fuel tube mounting state of the electromagnetic device D, the small 8 e protruding upward from the shaft portion 8a of the operating lever 8 is inserted through the lower magnetic pole piece 4 1 a and the fixed iron core 4 1 b. In the hole 4 1 c, the upper end is configured to be in contact with the movable iron core end face 43 a. Thus, the lever 8 is biased upward to give the spring force of the spring S2. Second, explain its role. When the electromagnetic coil 40 d is non-energized, since the electromagnetic coil is formed with any magnetic circuit, the movable iron core 43 is pressed by the spring force of the S 2 by pressing the upper operating lever 8 Recipe location. This state is shown in Fig. 4, and a gap c is formed between the valve stem 7a of the lower end 8b of the operating lever 8, between the movable iron core 4 3 4 3 a and the upper end 4 1 d of the fixed iron core 4 1 b, Therefore, the valve body 7 can be closed by the spring force of the first spring S1, and the electromagnetic coil 4 can be operated when the engine is restarted, or when the engine is moved for a long time. 0 d can be used here, the electromagnetic coil 40 d forms magnetic electricity between the upper pole piece 4 2, the movable core 4 3 , the core 4 1 b , the lower pole piece 4 1 a, and the outer casing 4 4 The generated magnetic force, the movable iron core 4 3 can resist the first bullet 326 \ the total file \93\93118062\93118062 (replacement) - 2 the flange non-magnetic opening portion is installed before the first diameter of the shaft portion 43 2 spring 40d not 2 spring placed on the upper and the lower end of the valve body 1 曰 1 gap d. Block 4 〇 Re-powered. For example, the fixed iron is attracted to the fixed core 4 1 b side (below the bottom of Fig. 4) by the spring force of the second spring S 2 of the springs S1, 20 1276740. When the movable iron core 43 moves, the operation lever 8 and the valve body 7 also move downward at the same time, and the valve body 7 is opened and held by the valve seat 4, and is stopped in the fuel introduction pipe 30 and the fuel inflow chamber 6 as in the above-described embodiment. The steam can be discharged together with the fuel through the discharge port 10 and the discharge pipe 34, so that a good engine start can be performed. According to the second embodiment, since the operator only needs to perform the energization operation on the electromagnetic coil 40d of the electromagnetic device D at the time of starting the engine, the operation lever 8 can be greatly improved compared to the mechanical pressing operation. Operational. In particular, for a two-wheeled vehicle, the driver can perform the aforementioned energization operation while riding a two-wheeled vehicle. Further, since the energization time can be started in a short time when the engine is started early, the battery power is not consumed, and it is more suitable for a two-wheeled vehicle having a smaller battery capacity than an automobile. Further, when the engine is started, when the battery motor is driven to synchronize with the battery motor, the electromagnetic coil 40d of the electromagnetic device is energized. * When the engine is started, the stagnant steam can be discharged frequently, and the startability can be further improved. Further, if the electromagnetic motor 40d is connected in series with the circuit of the battery motor, the electric switch for energizing the electromagnetic coil and the operation of the electric switch are not necessary. Further, when the engine is deactivated and the battery motor is driven off after the explosion is completed, the electromagnetic coil 40 d can be automatically turned into a non-energized state. Fig. 5 shows another embodiment of the fuel hose of the present invention. Here, only the different portions thereof will be described. The fuel pipe 50 has: a first fuel flow path 51a formed in the vertical direction; and, from the first fuel flow path 51a 21 326\total file\93\93118062 \93118062 (replacement) - 2, the second fuel flow path 5 1 b formed at the upper end of the 1276770 is formed on the left side; the valve seat 4 is formed in the second combustion flow path 5 1 b, thereby being divided into the fuel inflow chamber 6 and Feed 4 is not out of chamber 5. Further, the injection valve hole opened below the fuel inflow chamber 6 is inserted into the inflow side end portion of the support fuel injection valve J, and the fuel introduction pipe 30 is opened to the upper side of the fuel flow chamber 6. On the other hand, the fuel discharge chamber 5 formed toward the left side has a discharge port 10 port downward, where the discharge port 10 is connected to the discharge pipe 34, and the atmosphere opening portion 34a of the discharge pipe 34 is opened. A certain position that you want. Further, since the valve body and the lever are the same as those of the first embodiment, the same reference numerals are used. According to the fuel pipe, since the fuel discharge chamber 5 and the fuel introduction pipe 30 are disposed on the side, the height of the longitudinal axis X - X of the fuel injection valve J can be shortened, in particular, such as a two-wheeled vehicle.
