  • Fuel injector having improved parallelism of impacting armature surface to impacted stop surface
    Patent number: 5494223
    Abstract: A non-ferromagnetic member is disposed between, and joined to, a ferromagnetic fuel inlet tube and a ferromagnetic valve body structure. The valve body structure is fitted to the non-ferromagnetic member by telescoping the upper axial end of the valve body structure over the O.D. of the lower end of the non-ferromagnetic member and by guiding the armature on a cylindrical guide surface in a bore of the valve body structure at a location that is axially below the axial location where the upper end of the valve body structure and the lower end of the non-ferromagnetic member telescopically engage. For given part tolerances and given tolerances in tooling that is used to assemble the parts, closer tolerance in parallelism of the impacting armature end surface to the impacted fuel inlet tube end surface is obtained.
