ABSTRACT:
A fuel injector is described, particularly for fuel injector systems of internal combustion engines, including an actuator, a valve needle actuatable by the actuator for actuation of a valve-closure member, which together with a valve-seat surface forms a sealing seat, and a swirl device, having at least one swirl channel through which fuel flows having a tangential component regarding a longitudinal axis of the fuel injector. The axial position of a bypass disk, which is mechanically linked to a valve needle, determines a cross section of at least one bypass channel, which bypasses the at least one swirl channel without a tangential component.
