  Rexroth Rexroth pump suction and pressure oil from the plunger in a reciprocating movement of the plunger jacket to complete. When the plunger located in the lower position, Rexroth two plunger sleeve hole is opened, the plunger comprising a pump body cavity and oil passages communicating the fuel chamber quickly filled with oil. When the top of the cam roller to the roller body, the plunger will rise. Room from the plunger begins to move up to the front end surface of the plunger hole is blocked up. In this period of time, due to the movement of the plunger, the fuel is extruded from the oil chamber, the flow of oil passage. So this is called pre-travel lift. When the plunger block the hole, began to pressure oil process. Plunger up, a sharp increase in oil pressure oil chamber. When the pressure exceeds the force of the spring and the upper part of the hydraulic valve, the valve on top of the open, the fuel is pressed into the tubing to the injector.

  Rexroth柱塞套上的進(jìn)油孔被柱塞上端面*擋住的時(shí)刻稱為理論供油始點(diǎn)。柱塞繼續(xù)向上運(yùn)動(dòng)時(shí)，供油也一直繼續(xù)著，壓油過(guò)程持續(xù)到柱塞上的螺旋斜邊讓開(kāi)柱塞套回油孔時(shí)為止，當(dāng)油孔一被打開(kāi)，高壓油從油室經(jīng)柱塞上的縱向槽和柱塞套上的回油孔流回泵體內(nèi)的油道。此時(shí)柱塞套油室的油壓迅速降低，出油閥在彈簧和高壓油管中油壓的作用下落回閥座，噴油器立即停止噴油。這時(shí)雖然柱塞仍繼續(xù)上行，但供油已終止。Rexroth柱塞套上回油孔被柱塞斜邊打開(kāi)的時(shí)刻稱為理論供油終點(diǎn)。在柱塞向上運(yùn)動(dòng)的整個(gè)過(guò)程中，只是中間一段行程才是壓油過(guò)程，這一行程稱為柱塞的有效行程。
