Abstract: A fuel injector for an internal combustion engine includes a preassembled permanently mated needle and valve body group contained in a main housing assembly. The valve body group is assembled so that the maximum allowable stroke of the needle is established by a stop abutment, which is permanently attached to the valve body. An injector assembled according to the present method does not require the use of various shims in order to set the air gap. Moreover, precision grinding is not needed to establish the needle lift.

Abstract: A plastic molded fuel rail includes a plurality of core fuel injector assemblies molded within the fuel rail. Each core fuel injector assembly includes a magnetic core, electrical coil bobbin having electrical contacts extending therefrom, and axial fuel passageway. The magnetic core, coil bobbin assembly, and electrical contacts are hermetically sealed from the fuel passageways. An armature and sleeve including a needle and seat valve are inserted into the core fuel injector assemblies to provide fuel injectors. Trimming resistors are appropriately selected connected in series between each fuel injector and a corresponding electronic driver to achieve substantially uniform fuel flow through each fuel injector of the fuel rail.

Abstract: A fuel injector having major components formed by an injection molding process. A coil bobbin assembly is positioned within a magnetic permeable core. An injection molding process provides a plastic housing with the magnetic core and coil bobbin assembly hermetically sealed therein. The molding process also provides a fuel passageway through, and hermetically sealed from, the magnetic core and coil bobbin assembly.

Abstract: A fuel injector for an internal combustion engine includes a housing for receiving liquid fuel 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, and a valve element positioned to cooperate with the orifice plate and to control the flow of fuel from the injector, with the valve element comprising a generally planar first segment which is immovable with respect to the injector housing and a second segment cantilevered from the first segment and having an armature attached thereto so that fuel will be allowed to flow from the injector when the injector solenoid coil is excited.

Abstract: An apparatus assembly for use in an electroplating cell having an electrolyte and one or more sacrificial anodes, comprising: an electrically conductive magazine (elongated steel ribs) defining a sliding supportive track for electrically conductive articles to be coated, said magazine being supported for turning about an axis generally perpendicular to said track, said magazine providing freedom for sliding movement of such articles along said track to either side of said axis during each half-revolution of the magazine about the axis; means for establishing a current throw through said electrolyte between said anode and articles along planes generally parallel to said axis; and means for rotatably driving said magazine about said axis so that each of said articles will experience electrolyte flow reversal and a generally equal length path of movement through said electrolyte for each revolution of the magazine about said axis.
