Abstract

Exemplary fuel injectors for use in fuel injection devices are disclosed. An injector may have a control chamber, which can be selectively relieved of pressure by means of a pilot valve in order to control a nozzle needle stroke of an axially displaceable nozzle needle of the injector. The fuel injector may have at least one nozzle on a first end, and the control chamber on a second end of the nozzle needle. The control chamber may be sub-divided by a throttle plate accommodated therein into a first chamber and a second chamber, with the second chamber being positioned closer to the nozzle, and the two chambers communicating with each other via the throttle plate. First and second resilient elements may be accommodated in a pre-stressed manner against the throttle plate in the first chamber and in the second chamber, respectively.
