Flow area armature for fuel injector

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