摘要： An engine fuel injector (10) having a fuel inlet tube (12) and a biasing spring (56) loading a solenoid actuated injection valve (50) within the injector (10) is provided with a calibration assembly (58) combining the calibration member (74) or tube with an internally mounted fuel inlet filter (76). The calibration member (74) may include a body (78) with an enlarged end (88) that is interference fitted within the fuel inlet tube (12) and an opposite stepped in end (80) forming a seat (82) which is engaged by the biasing spring (56). The fuel filter (76) has an enlarged annular base (92) fixed within the enlarged end (88) of the calibration member (74) and having an associated filter screen (98) or element through which fuel passing through the calibration member is filtered for passage through the injector (10). The filter screen (98) may extend completely within the calibration member (74), or alternatively, can project outward from the enlarged end (86) of the calibration member (74) into the inlet end (86) of the fuel inlet tube (12). Advantages in the ease of calibration, reduced assembly costs and improved filtration of fuel are provided.

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 injector that includes a flying armature movable relative to a pintle stop, and an electromagnetic circuit configured to move the flying armature away from the pintle stop prior to accelerating the armature toward the pintle stop as part of moving the pintle to open the fuel injector. The flying armature increases the total force applied to the pintle to open the fuel injector by supplementing the static force imparted to the armature by a magnetic field with an impact force imparted by the armature being in motion toward and impacting with the pintle stop. The arrangement of magnetic circuit devices and materials used to make the magnetic circuit devices cooperate to provide a reversing force that urges the armature away from before urging the armature toward the pintle stop, and increases the rate at which the force that urges the armature toward the pintle stop increases.

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 method of assembly of a fuel injector having a valve plunger reciprocable in a guide tube for movement from a closed position engaging a valve seat to an open position engaging a valve stop by energizing of a solenoid coil to move the plunger against a biasing spring, wherein the method includes setting the valve stop at a position effective to establish the desired valve stroke, and fixing the valve stop to the guide tube by first laser spot welding the valve stop in the guide tube to fix the position of the valve stop without changing the set gap, and then laser seam welding the valve stop in the guide tube at an axial location beyond the spot welds, relative to a plunger-engagable end of the valve stop, to provide a hermetic seal around the valve stop.

摘要： A fiber optic light line unit provides a uniform linear beam of illumination onto a target, such as a traveling web. A number of fiber optic bundles have distal ends that are butted together end to end to create a long, seamless line of uniform strip lighting. The unit has a housing in which distal portions of the fiber optic bundles fan out so that the termini of the fibers are arrayed in a single continuous fiber row at a distal face plate of the housing. The ends of the row of each bundle abut the ends of the adjacent row from another bundle. In one embodiment the housing has first and second halves that sandwich the fiber termini, and there are respective sawtooth or similar recesses that each hold a respective fiber end or terminus. A cylindrical lens can be disposed with its axis across the linear beam of light. The fibers are held with their termini at a predetermined slant angle, e.g., thirty degrees, so that the light emanating from the unit impinges on a target at an angle. This reveals defects that may be oriented in the travel direction of the web.

摘要： A method for externally adjusting the axial length of a solenoid actuated fuel injector includes the step of externally forming a helical scribe mark in a housing component, thereby changing the axial length of the injector. By adjusting the length of the helical scribe mark and the depth of the scribe mark, and by measuring the stroke or the flow rate of the injector, the stroke or the flow rate of injector may be set precisely. The external adjustment of the length of the housing component may be made in cartridge form as well as in final assembly form of the fuel injector complementing the manufacturing process versatility.

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.
