ABSTRACT:
A fuel injector for fuel-injection systems of internal combustion engines, e.g., for the direct injection of fuel into the combustion chamber of an internal combustion engine, includes an actuator, a valve needle which is in operative connection to the actuator and acted upon by a restoring spring in a closing direction, to actuate a valve-closure member which forms a sealing seat together with a valve-seat surface, and an adjustment sleeve, which provides the restoring spring with an initial stress. The adjustment sleeve has a cup-shaped design and an eccentric bore in a base, which is in variable alignment with an eccentric bore in a base of a cup-shaped inner sleeve able to be inserted into the adjustment sleeve.
