Abstract
A fuel injector, in particular a fuel injector for fuel-injection systems of internal combustion engines has a piezoelectric or magnetostrictive actuator, a valve closure member which can be actuated by the actuator via a valve needle and which cooperates with a valve seat face to form a sealing seat, and a translating device arranged between the actuator and the valve needle for translating an actuator lift of the actuator into a larger valve needle lift of the valve needle. In this context, the translating device includes at least one lever plate having at least one rigid lever segment running radially.
