More Information
Summary:A fuel injector, particularly an injector for fuel-injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator and a valve-closure member which is operable by the actuator with the aid of a valve needle and which cooperates with a valve-seat surface to form a sealing seat. The actuator, at a first end face, abuts against a supporting member that has at least one cut-out through which at least one segment of an actuating sleeve projects. The actuating sleeve, at a first end, acts upon the valve needle, and at a second end, embraces the actuator at a second end face of the actuator facing away from the first end face of the actuator.
