Abstract
A fuel injection valve for internal combustion engines, having a valve body () in which a bore () is embodied that is defined on its end toward the combustion chamber by a valve seat () at which at least one injection opening () originates. The hollow valve needle () is located longitudinally displaceably in the bore () and has a valve sealing face () on its end oriented toward the valve seat (). A first sealing region () and a second sealing region () are embodied on the valve sealing face (), and upon contact of the hollow valve needle () with the valve seat (), the first sealing region () upstream of the at least one injection opening () and the second sealing region () downstream of that injection opening effect sealing between the valve sealing face () and the valve seat () (FIG.).
