Zusammenfassung:	PROBLEM TO BE SOLVED: To reducing the space of a fuel injection valve and the required length of the valve element by producing the two step releasing stroke movement of the valve element by a valve spring providing load to the closing direction of the valve element and the valve adjusting element transmitting the force loaded with the high pressure of the fuel to the valve element. SOLUTION: The two step releasing stroke movement of a valve element 1 is produced by providing spring load in the closing direction of the valve element 1 to the valve spring 51 to press the valve seat 15 and then to affect to the valve element 1 during partial stroke of the valve element 1 and to transmit to the valve element 1 by a valve adjusting element formed by an axially movable sleeve 31 disposed between the valve element 1 and the valve hole 3 the additional force loaded by the fuel pressure. This allows the required structuring space in the fuel injector valve, and the required length of the valve element 1 to be reduced.
