ABSTRACT:
A fuel injector has an actuator which is situated in an actuator housing connected by force-locking to a valve member at an end on the valve-needle side. The actuator is braced on the end of the actuator housing which is opposite thereto. A compensation section of the actuator housing is made of a material having virtually no, or having negative, temperature expansion, so that the temperature expansion of the actuator housing and the valve member, in the sequence up to a valve-sealing seat, essentially corresponds to the temperature expansion of the actuator and transmission elements situated up to the valve-sealing seat. The actuator housing is surrounded radially on the outside by a fuel chamber through which fuel flows.
