Claim:
A fuel injector for a fuel injection system of an internal combustion engine, comprising: an energizable actuating element; a valve seat element; a rigid valve seat provided on the valve seat element; and a valve closing element that is axially movable along a valve longitudinal axis and that works in conjunction with the rigid valve seat so as to open and close a valve, wherein: at least one outlet opening is provided downstream from the rigid valve seat, the valve closing element and the valve seat element being designed so that an opening movement of the valve closing element is fuel-pressure-assisted, wherein: the opening movement of the valve closing element is directed away from the at least one outlet opening, a closing movement of the valve closing element is directed toward the at least one outlet opening, and the valve closing element has an inner through hole through which a fuel flows in a direction that is opposite to the opening movement of the valve closing element, the valve closing element and the valve seat element configured to reverse the direction of fuel flow between the through hole of the valve closing element and the at least one outlet opening.
