摘要： The present application relates to a pump unit (1) for a fuel injection system. The pump unit (1) has a low pressure fuel supply line (11) and a high pressure fuel outlet (13). A pumping chamber (5) having a plunger (15) is operable to perform a pumping cycle comprising a pumping stroke and a filling stroke. The pump unit (1) also includes an inlet valve (7) having an inlet valve member (19) movable between an open position for permitting the supply of fuel to the pumping chamber (5) from the low pressure fuel supply line (11) and a closed position for inhibiting the supply of fuel from the pumping chamber (5) to the low pressure supply line (11). An outlet valve (9) is provided in the high pressure fuel outlet (13). The pump unit (1) also includes means (39) for coupling the plunger (15) to the inlet valve member (19). The present application also relates to a method of operating a pump unit (1).
摘要翻译：本申请涉及用于燃料喷射系统的泵单元（1）。泵单元（1）具有低压燃料供应管线（11）和高压燃料出口（13）。具有柱塞（15）的泵送腔室（5）可操作以执行包括泵送冲程和填充冲程的泵送循环。泵单元（1）还包括具有入口阀构件（19）的入口阀（7），所述入口阀构件在允许从低压燃料供应管线（11）向泵送腔室（5）供应燃料的打开位置之间移动，以及用于阻止从泵送室（5）向低压供应管线（11）供应燃料的关闭位置。出口阀（9）设置在高压燃料出口（13）中。泵单元（1）还包括用于将柱塞（15）联接到入口阀构件（19）的装置（39）。本申请还涉及一种操作泵单元（1）的方法。
