    摘要： A fuel injector having a fuel inlet, a fuel outlet, and a fuel passageway extending along an axis between the fuel inlet and the fuel outlet. The fuel injector includes a body having an inlet portion, an outlet portion, and a neck portion disposed between the inlet portion and the outlet portion. An adjusting tube is disposed within the neck portion of the body. A spring is disposed within the neck portion of the body, the spring having an upstream end proximate to the adjusting tube and a downstream end opposite the upstream end. A filter assembly is disposed within the tube assembly to provide a reaction member for the spring. An armature having a lower portion is disposed within the neck portion of the body and displaceable along the axis relative to the body. The downstream end of the spring is disposed proximate to the armature, the spring applying a biasing force to the armature. A valve seal is substantially rigidly connected to the lower portion of the armature. The fuel injector includes a modular valve group subassembly that is connected to a modular coil group subassembly.

    摘要： A fuel injector for use with an internal combustion engine. The fuel injector comprises a valve group subassembly and a coil group subassembly. The valve group subassembly includes a tube assembly having a longitudinal axis that extends between a first end and a second end; a seat that is secured at the second end of the tube assembly and that defines an opening; an armature assembly that is disposed within the tube assembly; a member that biases the armature assembly toward the seat; an adjusting tube that is disposed in the tube assembly and that engages the member for adjusting a biasing force of the member; a filter that is located at the first end of the tube assembly and that has an integral retaining portion; an O-ring that circumscribes the first end of the tube assembly and that is maintained by the retaining portion of the filter; and a first attachment portion. The coil group subassembly includes a solenoid coil that is operable to displace the armature assembly with respect to the seat; and a second attachment portion that is fixedly connected to the first attachment portion.

    摘要： A fuel injector having a fuel flow rate set by injector stroke is disclosed. The fuel injector includes a housing having a hollow passage and a seat disposed at one end of the hollow passage. A needle is slidably mounted in the hollow passage. The needle is operable between a first position wherein the needle engages the seat and a second position wherein the needle is disposed away from the seat. A first flow area is formed by a minimum frusto-conical area between the seat and the needle when the needle is disposed away from the seat. The fuel injector also includes an opening at the one end of the hollow passage proximate to the seat. The opening has a second flow area larger than the first flow area. A method for setting a gaseous fuel injector flow rate with injector stroke is also disclosed.

    摘要： A method for making a valve assembly is disclosed. The method includes providing a first work piece having a longitudinal axis and a first end and providing a second work piece having a surface. The method also includes disposing the first work piece and the second work piece axially between a pair of aligned elements that are relatively movable toward and away from each other along the longitudinal axis of the first work piece. Additionally, the method includes relatively moving the pair of aligned elements toward each other to axially clamp the first work piece and the second work piece and actuating the pair of aligned elements and delivering to the first work piece and the second work piece a controlled clamping force that acts to coin a zone of surface contact between the first end and the surface. Further, the method includes repeating the actuating of the pair of elements a plurality of times. An apparatus used to perform the method is also disclosed.
