The fuel injection valve contains excitable actuator, e.g. magnetic coil, co-acting with stopper needle (4), forming sealing seat (6) with valve seat body (5). In valve seat body is formed at least one injection spray port (7).On front side (39) of valve seat body, facing combustion chamber, is formed protrusion (38), into which open injection spray ports.
