    • The fule injector for an i.c. engine improved valve structure whose valve-opening pressure is directly proportional to the fuel pressure. The fuel injector includes a nozzle holder having a value seat, a needle valve moveably mounted in the nozzle holder and biased against the valve seat by a nozzle spring acting on a movable spring seat fitted therebetween and a plunger moveably mounted in the nozzle holder and having one end on which fuel pressure acts. An actuator rod is disposed between the plunger and moveable spring seat with a small distance provided between the actuator rod and the spring seat. A plunger spring acts on the plunger to urge the latter agaisnt the fuel pressure acting on the plunger.
    • 用于静电注射器 发动机改进的阀门结构,其开启压力与燃料压力成正比。 燃料喷射器包括具有阀座的喷嘴保持器,可移动地安装在喷嘴保持器中的针阀,并通过作用在安装在其上的可动弹簧座上的喷嘴弹簧偏置在阀座上,以及可移动地安装在喷嘴座中的柱塞, 燃料压力起作用的一端。 致动器杆设置在柱塞和可动弹簧座之间,具有设置在致动器杆和弹簧座之间的小距离。 柱塞弹簧作用在柱塞上以促使柱塞弹簧升高作用在柱塞上的燃料压力。
