原裝威格士VICKERS單泵雙聯(lián)泵Vickers單體泵是用于產生噴油器（或噴射器）的噴射壓力的裝置。對于采用Vickers單體泵式電控燃油噴射系統(tǒng)的發(fā)動機來說，有幾個氣缸，就有幾個Vickers單體泵，Vickers單體泵是第二代電控燃油噴射系統(tǒng)，按照高壓產生裝置的不同，可將燃油噴射系統(tǒng)分為分配泵、直列泵、泵噴嘴和Vickers單體泵電控燃油噴射系統(tǒng)。[1]
工作原理
Vickers單體泵的組成：Vickers單體泵由柱塞套筒、柱塞、彈簧座、回位彈簧、出油閥、出油閥彈簧、出油閥座、出油閥壓緊螺帽等零件組成。V10F 1S2T 1C2H 20

原裝威格士VICKERS單泵雙聯(lián)泵１、出油閥的作用
（１）防止噴油后滴油，提高關閉速度：停止供油時，出油閥減壓帶的下沿一進入導管時，高壓油管與泵室的通路便被切斷。當出油閥*座落后下降了一距離ｈ，因而高壓油管的容積得到增大，使油壓迅速地下降１MPa～２MPa，斷油迅速干脆，防止了因油壓的波動和“管縮油漲”而產生噴后滴油。
Ｐ泵>Ｐ簧＋Ｐ殘—開；
Ｐ泵簧＋Ｐ殘—關。
（２）防止噴油前滴油，提高噴射速度：噴油泵供油時，待油壓高于出油閥彈簧的預緊力和高壓油管內的殘余壓力后，出油閥升起，其密封錐面離開閥座。必須等到出油閥上的減壓帶*離開閥座的導向孔時，泵油室的燃油才能進入高壓油管。
（３）防止燃油倒流，使高壓油管內保持一定的殘余壓力
原裝威格士VICKERS單泵/Vickers雙泵產品型號２、出油閥的構造
（１）出油閥的圓錐部是閥的軸向密封錐面，閥的錐部在導孔中滑動配合起導向作用。尾部加工有切槽，形成十字形斷面，以便使燃油通過。出油閥中部的圓柱面叫減壓帶，它與密封錐面間形成了一個減壓容積?，F(xiàn)貨：3129015,55619,85063,85381,51413,4027025,6652130,6652103,6652000,7000-41441-0000000,7000-12721-0000000,7000-40001-6330500

（２）出油閥和閥座是精密偶件，采用優(yōu)質合金鋼制造，其導孔、上下端面及座孔經過精密的加工和研磨，配對以后不能互換。
（３）閥座的下端面和柱塞套筒的上端面是精密加工嚴密貼合，它是通過壓緊螺帽以規(guī)定的扭緊力矩來壓緊的。壓緊螺帽與閥座之間有一定厚度的銅制高壓密封墊圈。出油閥壓緊螺帽和殼體上端面間還有低壓密封墊圈。
（４）在出油閥壓緊螺帽內腔裝有帶槽的減容器，以減小內腔空間的容積，促進噴停迅速，限制出油閥zui大升程的作用?？蛇x的流量控制或單穩(wěn)分流閥蓋提供更大的靈活性。
單穩(wěn)分流閥蓋維持幾乎恒定的流量給*回路而把多余流量分流給第二回路。去往第二回路的流量取決于泵的流量。*回路受內裝溢流閥保護，但必須第二回路提供外界溢流閥。
性能葉片頂端／定子載荷小，允許高壓工作。由于進油口流道結構給出均勻的油液加速度，因而給出較好的灌注，特別在低進口壓力下更是如此，所以可以高轉速。
低成本Vickers的高效率結構產生了每圓線泵投資的額外功率，給工業(yè)提供了每馬力容量的低泵成本。
這種元件的上乘設計使其壽命更長 ... 它們已被證實它們能耐受如象開溝機、反鏟挖掘機及拖拉機之類的繁重用途。
原裝威格士VICKERS單泵雙聯(lián)泵進油口壓力腔和出油口壓力腔是徑向對置的。結果，壓力誘發(fā)的徑向載荷是平衡的 ... 軸承只需承受外界載荷。
流量控制蓋把至工作系統(tǒng)的流量限制于希望的zui大流量。多余流量分流回油箱。在雙泵中，軸端泵的流量與轉速成正比例。
流量控制蓋還包括一個溢流閥以限制zui高系統(tǒng)壓力。
流量控制的典型應用是在動力轉向裝置中，其中在發(fā)動機的中速至高速范圍內提供恒定油源。
