A fuel injector, in particular for fuel injection systems of internal combustion engines. Such an injector is characterized by a magnetic circuit containing a core, a solenoid, an armature, and a movable valve needle having a valve closing body that cooperates with a fixed valve seat), the valve seat being formed on a valve seat body), and a valve seat carrier into which the valve seat body is introduced. The outer circumference of the valve seat body has a sawtooth-like structure for establishing a fixed connection to the valve seat carrier. The fuel injector is suitable in particular for use in fuel injection systems of mixture-compressing, externally ignited internal combustion engines. |
