Abstract: A vented solenoid armature/valve member assembly comprises an armature joined to a valve member by a vented screw. The screw includes a vent hole extending its complete length in order to accommodate fluid displacement that occurs when the armature/valve member assembly is moved by energizing the solenoid. By providing venting through the screw itself, several advantages are achieved including the elimination of vent holes in the valve member as well as the ability to use a relatively larger screw to hold the armature and valve member together. This in turn results in a more robust armature/valve member assembly. The present invention finds particular application in hydraulically actuated electronically controlled fuel injectors in which initiation of injection events is controlled by a solenoid actuated valve.
