摘要： A protection device for a lower guide system of a fuel injector includes a debris shield deflecting a fuel flow around a lower guide system and a particle trap collecting particles contained within the fuel flow. By deflecting the fuel flow towards flow passages around the lower guide system, the particles contained in the fuel flow are prevented from entering a lower guide area, such as a radial gap between the stationary components of the lower guide system and the moving component of the valve assembly. The particle trap may be defined in a lower housing of the fuel injector or may be integrated in the debris shield. The debris shield may be integral with a valve assembly or may be a separate component. A permeable area may be integrated in the debris shield to enable partial flow therethrough.

摘要： An upper guide system for a solenoid actuated fuel injector of an internal combustion engine includes an armature and a guide ring having a cylindrical shape and surrounding the armature and positioning the armature in a radial direction. The location of the upper guide system is substantially in the same axial location as the radial magnetic forces imposed on the armature. Features such as flutes or grooves are disposed on an outer diameter surface of the armature and/or holes through a body portion of the armature. Accordingly, the response performance of the solenoid actuated fuel injector is improved.

摘要： A dual-coil outwardly-opening fuel injector including a fuel tube connected at a lower end to a lower injector housing. Within the fuel tube are a lower (opening) solenoid pole piece, a specially-formed armature, and an upper (closing) solenoid pole piece. A seat assembly including an injector nozzle, swirler, and valve seat are adjustably threaded into the lower housing. A pintle assembly, including a solid pintle portion supporting a valve head and a tubular portion welded thereto, is axially disposed within the fuel tube and is welded to the armature which is spaced from the lower pole piece by a distance equal to the opening stroke of the valve. A return spring adjustment mechanism disposed on the upper pole piece engages the upper end of the pintle assembly for varying the closing force of the return spring. Opening and closing solenoid preassemblies are mounted external to the fuel tube for magnetically engaging the pole pieces and armature within in known fashion.

摘要： An upper guide system for a solenoid actuated fuel injector of an internal combustion engine includes an armature having a first diameter section, a reduced diameter second section, and a concave portion at the transition between the first and second sections. The guide system also includes a guide shaped to extend into the concave portion of the armature and includes a central opening that slidably receives the second diameter section. The guide positions and guides the armature in a radial and an axial direction. The guide is assembled in an axial location that is close to the axial location of the center of the magnetic force acting on the armature. The guide system allows for a desired relative large guide length to diameter ratio.

摘要： 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.

摘要： A fuel swirler plate for improving atomization of fuel in a fuel injector. A plurality of identical fuel supply passages is formed in the plate, each passage including an outer fuel reservoir region; a region having converging walls wherein fuel is accelerated and turned partially tangential to the axis of the plate and fuel injector; a metering region wherein flow is regulated; and an exit region wherein the fuel is combined with similar fuel flows from the other passages to form a high velocity swirl annulus between the swirler plate and a pintle ball of the fuel injector. An advantage of the novel swirl plate over prior art plates is that, when the injector valve is closed, only a very small volume of fuel resides in the swirl annulus between the pintle ball and the exit region of the plate, and such residual fuel is urged rotationally and becomes the leading edge of a new vortex the next time the valve is opened, thus minimizing SAC spray formation. The present invention is useful in fuel cells, burners, and in both direct injection and port injection fuel injectors of internal combustion engines.
