Zusammenfassung:A fuel injector that includes a sliding armature, decoupled armature, or flying armature movable between a pintle stop and a housing stop. Flying armatures are generally used to increase the total force applied to the pintle stop for lifting the pintle off a nozzle seat to open the fuel injector. When the fuel injector is turned off, a housing stop is arranged to absorb kinetic energy present in the flying armature so that the kinetic energy is not imparted to the nozzle seat.
