摘要： A fuel injector comprising a valve needle, engagable with the seating to control fuel flow through a fuel outlet, the valve needle having a thrust surface oriented such that the application of fuel under pressure thereto applies a force to the valve needle urging the valve needle away from the seating. The fuel injector also comprises a valve member for controlling fuel pressure within a control chamber and a piston member slidable within a bore and defining, with the bore, the control chamber. The piston member is exposed to fuel pressure within the control chamber and is arranged to transmit a force applied by the fuel pressure to the valve needle. The piston member has an effective surface area exposed to the fuel pressure which is greater than that of the thrust surface so as to urge the valve needle towards the seating.
摘要翻译：一种燃料喷射器，包括阀针，可与所述座接合，以控制通过燃料出口的燃料流动，所述阀针具有取向的推力面，使得在压力下的燃料的施加对所述阀针施加力以促使所述阀针远离从座位。燃料喷射器还包括用于控制控制室内的燃料压力的阀构件和可在孔内滑动并且与孔一起限定控制室的活塞构件。活塞构件暴露于控制室内的燃料压力，并且被布置成将由燃料压力施加的力传递到阀针。活塞构件具有暴露于燃料压力的有效表面积，该有效表面积大于推力表面的燃料压力，从而将阀针推向座椅。
