Abstract
A fuel injector, such as a fuel injector for fuel injection systems in internal combustion engines, includes a valve needle, the valve-closure member of which cooperates with a valve seat surface to form a sealing seat, and includes an armature engaging with the valve needle, the armature being arranged on the valve needle in an axially movable manner and being damped by a damping element including an elastomer. A ring space is formed between damping element and the valve needle, which is filled with fuel, the ring space being in contact with a throttle gap.
