Abstract:
Disclosed is a fuel injection valve for internal combustion engines having a valve body in which a hollow valve needle is disposed longitudinally displaceably in a bore. The hollow valve needle, on its end toward the combustion chamber, has a conical valve sealing face, which cooperates with a conical valve seat disposed on the end of the bore toward the combustion chamber. A longitudinal bore is embodied in the hollow valve needle, and a valve needle is disposed in it and, with a valve contact face embodied on its end toward the combustion chamber, likewise cooperates with the valve seat. The tip of the hollow valve needle toward the combustion chamber is formed by a chamfer.
