Abstract

The fuel injector has a valve plate (1) which forms a valve seat (7) for a valve bolt (5), where the valve bolt is guided in a sealing sleeve (8) in a slidable manner. The valve bolt is movable with the actuation of an actuator unit enlarged by the valve seat in an opening position. A receiving plate (18) is provided between the valve plate and a chock plate (2).
