Abstract
A fuel injector (1) is described, particularly for fuel injector systems of internal combustion engines, including an actuator (27), a valve needle (3) actuatable by the actuator (27) for actuation of a valve-closure member (4), which together with a valve-seat surface (6) forms a sealing seat, and a swirl device (15), having at least one swirl channel (18) through which fuel flows having a tangential component regarding a longitudinal axis (26) of the fuel injector (1). The axial position of a bypass disk (17), which is mechanically linked to a valve needle (3), determines a cross section of at least one bypass channel (19), which bypasses the at least one swirl channel (18) without a tangential component.

A fuel injector (1) for fuel injection systems of internal combustion engines, comprising an actuator (27), a valve needle (3) actuatable by the actuator (27) for actuating a valve-closure member (4), which cooperates with a valve-seat surface (6) to form a sealing seat, and having a swirl device (15), which has at least one swirl channel (18) through which fuel flows having a tangential component with respect to a longitudinal axis (26) of the fuel injector (1), wherein the axial position of a bypass disk (17), which is mechanically linked to a valve needle (3), determines a cross section of at least one bypass channel (19), which bypasses the at least one swirl channel (18) without a tangential component.
