Abstract
A fuel injector for an internal combustion engine has a nozzle needle that opens or closes at least one injection opening. At an end oriented away from the at least one injection opening, the nozzle needle has a step-shaped widening, which forms an end surface oriented toward the at least one injection opening. The end surface, an end surface of a first booster, and an end surface of a second booster delimit one side of a control chamber; an actuator moves the first booster and the second booster into or out of the control chamber.
