Abstract

A fuel injector for injecting fuel that is at high pressure into a combustion chamber of an internal combustion engine has an injection valve member triggered by an actuator and a coupler chamber; the actuator acts on the injection valve member and the injection valve member opens or closes at least one injection opening. The coupler chamber is located on the side of the actuator diametrically opposite the injection valve member; and the coupler chamber is filled with fuel that is at system pressure when the injection opening is closed.
