More Information
Summary:An electromagnetic injector for controlling a fuel quantity to be fed into an internal combustion engine includes a valve body displaceable by an electromagnetic coil system, the valve body acting together with a magnet armature of the electromagnetic coil system. The electromagnetic coil system includes at least two concentrically positioned coils integrated into the magnetic circuit so that in each case a first pole body is positioned between two adjacent coils, and the inner and outer coil are respectively adjacent to a second pole body, the first and second pole bodies are components of the magnetic circuit of the electromagnetic coil system, and in each case adjacent coils may have a common field current flowing through them in opposite directional sense to each other.
