Abstract

A fuel injector for fuel-injection systems of internal combustion engines includes an electromagnetic actuating element having a solenoid coil, a fixed core, an outer magnetic circuit component, and a movable armature for actuating a valve-closure element, which cooperates with a valve-seat surface provided on a valve-seat element. The injector is characterized by its extremely small outer dimensions. The flexibility in the installation of fuel injectors of varying valve lengths, which is made possible very simply due to the special modular design, is significantly increased in this manner. An optimized dimensioning of the electromagnetic circuit allows for a DFR (dynamic flow range) greater than 17, the DFR being defined as the quotient of qmax/qmin.
