ABSTRACT:
A fuel injector for the direct injection of fuel into the combustion chamber of a mixture-compressing internal combustion engine having external ignition includes a piezoelectric or magnetostrictive actuator and a valve needle, which, via a compensation element, is in operative connection to the actuator, a valve-closure member being formed on the valve needle, which cooperates with a valve-seat surface to form a sealing seat. The compensation element is filled with a rheological liquid.
