摘要： A pump head suitable for use in a fuel pump for a common rail fuel injection system, comprises a pump head housing defining a plunger bore and a pumping chamber. Fuel is pressurized within the pumping chamber by a plunger reciprocating within the plunger bore. The pump head housing includes an inlet valve arrangement for controlling fuel flow into the pumping chamber. The inlet valve arrangement includes a valve member movable between open and closed positions in response to fuel pressure within a gallery. The gallery communicates with an external chamber defined by a closure means externally mounted to the pump head housing. In use, the gallery communicates with a source of low-pressure fuel via the external chamber. The pump head housing has a projection which locates the closure member on the pump head housing.
摘要翻译：一种适合用于共轨燃料喷射系统的燃料泵的泵头包括限定柱塞孔和泵送室的泵头壳体。燃料通过在柱塞孔内往复运动的柱塞在泵送室内被加压。泵头壳体包括用于控制进入泵送室的燃料流的入口阀装置。入口阀装置包括响应于画廊内的燃料压力在打开位置和关闭位置之间运动的阀构件。画廊与由外部安装在泵头壳体上的封闭装置限定的外部室连通。在使用中，画廊通过外部室与低压燃料源通信。泵头壳体具有将封闭构件定位在泵头壳体上的突起。
