Abstract
A method is described for manufacturing a magnet coil for a valve in which first a metal base element of the valve is made available, then an electrically insulating winding support is mounted on the outer wall of the base element, and lastly a winding of the magnet coil is introduced into the winding support. Such a configuration of a magnet coil is suitable particularly in fuel injection valves which are used in mixture-compressing, spark-ignited internal combustion engines, but also in all other solenoid valves.
