Abstract
A fuel injector for a fuel injection system of an internal combustion engine includes an energizable actuator having a valve closure element actuable by the actuator by a valve needle, which coacts with a valve seating surface to form a sealing fit and which is held in the closed position by a return spring. The actuator acts on the valve needle via a sleeve-shaped needle driver that is separate from the valve needle, which is arranged in an axially movable fashion with respect to the needle driver, and a collar of the needle driver is engageable behind a needle collar of the valve needle at the end facing away from the return spring.
