1T A7 8025-1 .TWP-8/13 經濟部中央標準局員工消費合作社印製 B7五、發明説明() 可利用調整螺絲21來預施應力。 由於閥具本體9之選擇設計及在閥室23内的排氣開口 10,來自進氣口 4的氣體壓力會在閥具本體的密閉方向產 生一道力量。介於閥具本體座板間的密封可利用特別簡單 5 的方式來達成,因爲僅需將密封板設計成平面型即可。作 動桿12亦具有某一程度的彈性性質,這對閥具的開啓及閉 合是極爲重要的。 以下將舉一實例,閥具是在進氣口 4壓力爲8巴的情況 下操作,而在進氣歧管内的壓力則爲2.2巴(增壓式引擎)。 10 開口 10的面積約爲10平方厘米,而門本體9的閥具揚 升則爲0.25厘米。 如果此處使用的閥具是做爲序列噴射,除了具有傳統 的優點外,則更有可能特別提供一種控制系統設計,即特 別在啓動期間,在内燃機最初的第一及第二轉時,並無氣 15 體噴入。在此情況下,電腦控制可以最佳化方式來設定内 燃機所有的參數。完成設定後,燃料再行噴入。 可由圖示看出,根據本發明之閥具可以輕薄短小的設 計。利用這種方式,這種閥具不但可以應用在全新的進氣 歧管上,也重新安裝在現有的歧管上。 20 座板8同時亦做爲一閥具本體9的密封裝置及一止擋 件0 以上説明之閥具可以一種非常簡單及便宜的方式來製 造。閥具輸送的氣體量,在不需額外的花費下即可以很容 易地改變,即只要改變調整環即可,而該調整環則是經常 n m ---I —^Ί - m 1^1 - 一 (請先閱讀背面之注意事項再填寫本頁) 訂 银 本紙張&度適用中國國家標隼(CNS ) A4規格(210X297公釐) A7 8025-1.TWP-9/13 B7 五、發明説明() 需要的。其結果便是,該閥具即可在相對應的進氣期間輸 送氣體。 由以上的説明可以瞭解到該閥具可做不同的變化實 施。這些變化實施則都包括在本發明申請專利範圍所定義 5 的範圍内。 —in - HM I n (請先閱讀背面之注意事項再填寫本頁) t T 、ya 線 經濟部中央標準局員工消費合作社印製 -9- 本纸乐尺度適用中國國家標準(CNS ) Λ4規格(210X297公釐)
