    摘要： An injector fuel injection valve is guided at the lower end by a plastic valve guide mounted in a nozzle containing a valve seat engagable by the valve element. The valve guide includes inwardly protruding annularly spaced ribs having inner guide surfaces and defining spaced flow channels. The guide surfaces engage the circular or spherical exterior of the valve element to guide the element to properly aligned seating against the conical valve seat. The plastic or polymeric valve guide is preferably molded in place within the cup shaped metal nozzle but, if desired, the valve guide may be separately molded and subsequently inserted or snapped in place within the nozzle. A second plastic valve guide may be provided for guiding the upper end of an associated armature. A plastic or polymeric ring is molded in place or otherwise mounted within a groove around the outer surface of the armature and engagable with a cylindrical tube disposed within a main body of the injector to which the injection nozzle is secured.

    摘要： A fuel injector includes a flexural element connected to a valve armature for restricting radial movement of the armature within a fuel passage. The flexural element is flat and exerts no force on the valve when it is closed but is flexed when the valve is opened and supplements the valve spring force during closing of the valve. The flexural element also is used to set the valve stroke length equal to the element's thickness. A flat tool presses a valve ball into the armature while the ball is seated on a valve seat until the flexural element engages a seat related surface. Engagement of the tool with the flexural element fixed to the armature assures that the flexural element is in an unloaded flat position when the valve is closed and establishes the valve stroke when the valve assembly and seat are installed in the injector body.

    摘要： A vapor storage canister has an improved carbon bed loading pressure maintenance mechanism. A pressure plate is driven up indirectly, through a threaded shaft turned by a radially wound spiral spring, rather than by an axially compressed helical spring. This takes better advantage of the space available between the carbon bed and the lower end of the canister.

    摘要： An electromagnetic fuel injector comprises a body having a fuel inlet and a fuel outlet and a base comprising a valve seat sealably connected to the body. A disk-shaped armature disposed at the fuel outlet for controlling the flow of fuel has an upper surface and a lower surface that comprises a sealing interface with the valve seat. A ring-shaped flexural element comprising a plurality of spaced flexural legs is in contact with the injector body and the upper surface of the armature and provides a spring bias between the body and armature upper surface. When the injector is closed, spring bias between the body and armature upper surface maintains the armature in a sealing position with the valve seat, and when the injector is open, increased spring bias between the body and armature upper surface impels the armature to return to a sealing position with the valve seat.

    摘要： A method is provided for assembling a pole piece into an internal fuel passage of a fuel injector. The assembly method includes the steps of: (a) providing an endoskeletal injector tube, where the injector tube provides the fuel passage for the fuel injector; (b) forming at least one depression into an outer surface of the injector tube; (c) inserting an injector valve into the injector tube; (d) inserting the pole piece into the injector tube, wherein the pole piece is adjustable thereafter; and (e) affixing the pole piece within the injector tube, where an outer surface of the pole piece is in contact with an inner surface of the injector tube corresponding to the depressions, thereby creating a spring fit between the pole piece and the tube.

    摘要： A fuel injector for discharging fuel to an internal combustion engine is disclosed. The injector includes a nozzle body having a solenoid actuator, a pole piece with an axial extending fuel passage, a valve assembly including a reciprocably moveable armature operable against the bias of a spring member, a calibration tube extending through the pole piece fuel passage and operable to load the spring, an axially extending, drawn metal fuel tube having a first end defining an injector fuel inlet and a second end in communication with the axially extending fuel passage of the pole piece. The fuel tube includes features which extend radially inwardly in the wall of the fuel tube to define depressions in the outer surface of the wall which function, with a molded composite jacket to deter rotation of the tube. Additionally, the features define radial inward projections from the inner surface of the tube wall and may be used to position the filter assembly and to align externally installed components of the injector.
