Abstract

A fuel injector, in particular an injector for fuel injection systems of internal combustion engines, has a first actuator which cooperates with a first valve needle. A first valve closing body situated on the first valve needle cooperates with a first valve seat surface to form a first sealing seat. A second actuator cooperates with a second valve needle, and a valve-closing body situated on the second valve needle cooperates with a second valve seat surface to form a second sealing seat.
