Abstract
A fuel injector (1), in particular a fuel injector for fuel injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator (3) and a valve closing body (12) which can be actuated by the actuator (3) via an actuating path (6, 24, 10, 9), the valve closing body (12) working together with a valve seat surface (13) to form a sealing seat. A gap (24) is formed in the actuating path (6, 24, 10, 9) in the non-energized rest state of the actuator (3).
