Fuel injection valve for internal combustion engine

摘要

The fuel injection valve has an electromagnetic circuit with at least one magnetic coil (1), a metal inner core (2), a metal valve mantle (14) and an armature (22), for operation of a valve closure element (23). The coil fits in a radial gap (15) defined between the inner core and the valve mantle. The valve mantle contacts the inner core above and below the coil, with the valve mantle and the inner core coupled together at one or both points of contact.
