ABSTRACT:
A fuel injection valve for internal combustion engines, having a valve member that is guided so that it can slide axially in a bore of a valve body. The valve member has a valve sealing face on one end which cooperates with a valve seat face on the valve body and this valve member, on an end remote from the valve sealing face, is acted on in the closing direction toward the valve seat by a valve spring, as well as having another adjusting member that controls a two-stage opening stroke course of the valve member. In order to control the two-stage opening stroke course of the valve member, the adjusting member is embodied as an adjustable stop, in which the valve member comes into at least indirect contact with after passing through a partial stroke and which in a first position, is locked in its initial position and in a second position, can be moved in the opening direction by means of the valve member.
