Abstract

A fuel injector, in particular for fuel injection systems of internal combustion engines, has a valve closing body which can be operated by an actuator by a valve needle and which cooperates with a valve seat face to form a sealing seat. Swiveling toggle elements are situated between the actuator and the valve needle, so that the actuator acts on first lever arms of the swiveling toggle elements, and second lever arms are mechanically linked to the valve needle.
