A fuel injection valve for internal combustion engines, having a valve member guided axially displaceably, counter to a closing force, in a blind bore of a valve body. The valve member on an end toward the combustion chamber has a conical valve sealing face, with which the valve sealing face cooperates with a conical valve seat face on the inward-projecting closed end of the blind bore. A blind bore region, adjoins the conical valve seat face downstream, from which region injection openings lead into the combustion chamber of the engine. The blind bore wall region that receives the injection openings is embodied conically, and the injection openings have a certain minimum spacing from an upper and a lower end of this conical blind bore wall region.
