A fuel injection valve (1), which is designed in particular as an injector for fuel injection systems of air-compressing, self-igniting internal combustion engines, comprises an actuator (6) and a control valve (30). A valve closing member (31) of the control valve (30) can be actuated by the actuator (6). Furthermore, a force transmission element (37) is provided, which is arranged in the valve closing member (31). Furthermore, the valve closing member (31) is designed such that an end face (31) of the force transmission element (37) is acted upon by a pressure (p v) in a valve chamber (32) of the control valve (30). The force transmission element (37) transmits to the actuator (6) a force that results from the action of the pressure (p v) in the valve chamber (32) on the end face (31) of the force transmission element (37).
