A fuel injector (1) has an injection valve (7) having a movable pin (15) terminating with a shutter head (22); a tubular supporting body (4) having a feed channel (5); and a sealing body (17), in which a valve seat (16) of the injection valve (7) is defined; the shutter head (22) is truncated-cone-shaped, is located outside the sealing body (17), and, in a closed position, is pushed against the sealing body (17) in the opposite direction to the fuel feed direction; the pin (15) has a stop member (35), which is integral with the pin (15) and comes to rest on a top surface of the sealing body (17), when the pin (15) is in the open position opening the injection valve (7), so as to determine travel of the pin (15).
