Abstract
A fuel injector for fuel injection systems of internal combustion engines, in particular for direct injection of fuel into the combustion chamber of an internal combustion engine, is described, including a solenoid, an armature, which is acted upon by the solenoid in a closing direction by a return spring, and a valve needle, which is connected to the armature in a force-locked manner for actuation of a valve closing body, which together with a valve face forms a sealing seat. An adjusting element for adjusting the spring force of the return spring is situated in a connector sleeve which provides the fuel feed on the inlet side. The adjusting element is delimited toward the outside by a thin-walled sleeve, into which a disk-shaped throttle element having a throttle borehole is introduced as a separate insert part.
