    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 has 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 comprises a body, an armature, a spring, and a spring stop. The body has an inlet portion, an outlet portion, and a passage disposed between the inlet portion and the outlet portion. The armature is disposed within the passage and is displaceable along the axis relative to the body. The spring is disposed within the passage and applies a biasing force to the armature. The spring has a first end disposed proximate the armature and a second end opposite from the first end. The spring stop is disposed within the passage and has a first and second portion. The first portion includes at least one projection engaging the passage. The at least one projection extends obliquely with respect to the axis and in a direction general toward the inlet portion.
