Abstract
A fuel injector with a magnetic coil, which cooperates with an armature acted upon by a restoring spring, the armature forming an axially movable valve part together with a valve needle. A valve-closure member, which forms a sealing seat with a valve-seat member, is provided at the valve needle. An inner pole and an outer pole form a magnetic circuit with the magnetic coil. A membrane is positioned at an inflow-side end face of the inner pole, which includes at least one orifice, which is covered by the inner pole in the dosed state of the fuel injector.
