Abstract

A fuel injector for fuel injection systems of internal combustion engines. The valve includes an electromagnetic actuating element which has a solenoid, a solid core, an external magnetic circuit component, and a movable armature for activating a valve closing member which cooperates with a valve seat surface provided on a valve seat member. The valve has extremely small outer dimensions. By optimizing the dimensions of the electromagnetic circuit, the outer diameter of the external magnetic circuit component in the peripheral area of the solenoid is 10.5 mm<DM<13.5 mm. This increases the flexibility in installing fuel injectors having different valve lengths, which are made possible due to the special modular design. The valve is suitable as a fuel injector in particular for use in fuel injection systems of mixture-compressing, spark ignition internal combustion engines.
