Abstract
A fuel injector for fuel injection systems of internal combustion engines has an actuator and a valve needle actuatable by the actuator, which valve needle is in turn coupled to, and actuates, a valve closing body. The valve closing body and a valve seat surface of a valve seat body form a sealing seat. At least one injection opening is formed in the valve seat body, and an elastic vibration element penetrates the injection opening. The elastic vibration element is attached on the inlet side of the injection opening and leaves a portion of cross-section of the injection opening free.
