This patent describes a fuel injector for an internal combustion engine. It comprises: a housing adapted for receiving liquid fuel therein and having a terminal provision for connecting the injector to an engine control computer; a solenoid coil operatively connected with the terminal provision; an orifice plate containing at least one orifice for discharging fuel from the injector; a valve element positioned to cooperate with the orifice plate to control the flow of fuel from the orifice, with the valve element comprising a generally planar valve body comprising a reed spring having a first segment immovable with respect to the housing and a second segment movable cantilevered from the first segment, and an armature attached to the second segment so that fuel is allowed to flow when the coil is excited; and elastic means for urging the second segment into contact with the orifice so that the injector is normally in a closed position.
