Abstract
The armature has a tubular wall bounding a main axial through-hole. The upper axial end has a larger outside diameter than does the lower axial end. A portion of the tubular wall lying between these upper and lower ends has a frustoconical exterior surface. A single through-hole extends through the tubular wall at this frustoconical surface to non-perpendicularly intersect the main axial through-hole. The upper end of a needle valve is inserted into the lower axial end of the main through-hole, and the two parts are joined there by welding and/or crimping. The inserted end of the needle valve does not obstruct the single through-hole extending through the tubular wall so that fuel entering the armature via the open upper end of the main through-hole will change direction to pass out of the armature through the single through-hole in the tubular wall.
