ABSTRACT:
A fuel injector includes a measuring valve, a movable valve seat opened or closed by the measuring valve, a bobbin having a coil, an armature loosely fitted in one end of a through hole of the bobbin, a core inserted into the other end of the through hole, a nozzle having an injecting hole, a rod opening or closing the injecting hole and fixed to the movable valve seat, a diaphragm dividing a mixing chamber and a fuel chamber in the through hole, a fuel passage communicating between the mixing chamber and the fuel chamber, a first spring disposed between the movable valve seat and the nozzle, and a second spring disposed between the measuring valve and the armature. A measuring current supplied to the coil is smaller than an injecting current supplied to the coil, and the urging force of the first spring is larger than the urging force of the second spring.
