Title:
【発明の名称】磁束を作業ギャップから選択的にそらすことによる燃料噴射器の動流キャリブレーション
Document Type and Number:
Japanese Patent JPH07505939
Kind Code:
A
Abstract:
An electromagnetically operated fuel injector has a dynamic flow calibration mechanism in which a control rod that extends between and enters holes in both the stator and the armature is selectively positioned to divert some of the magnetic flux from the axial working gap between the stator and the armature such that the diverted magnetic flux passes through the control rod directly between the stator and the armature without passing through the working gap. A non-magnetic tube is disposed between the control rod and the stator and armature holes. The portion of that tube which is within the stator hole is joined to the stator while the portion which is within the armature hole provides guidance for the armature. In a bottom-feed version of fuel injector the tube also serves to prevent fuel within the injector from wetting the control rod. The fuel injector is dynamically calibrated by selectively positioning the control rod by use of an external tool that engages the control rod so that the diverted flux which is conducted between the stator and the armature is conducted through the control rod without passing through the working gap.
