    Abstract: A fuel injection valve for internal combustion engines, having a housing with a bore inside it that contains a longitudinally sliding outer valve needle which in turn contains a longitudinally sliding inner valve needle and the end of each valve needle oriented toward the combustion chamber controls at least one injection opening. The pressure in a control pressure chamber at least indirectly exerts a closing force on the outer valve needle and the pressure in a control pressure chamber at least indirectly exerts a closing force on the inner valve needle. The housing contains a control valve that has a valve chamber and a valve element contained in it, wherein the valve chamber has a connection to the leakage oil chamber, a continuously open connection to the control chamber and a connection to the control pressure chamber. The valve element can move between a end position, the valve element closing the connection to the leakage oil chamber and opening the connection to the control pressure chamber and a second end position, closing the connection to the control pressure chamber and opening the connection to the leakage oil chamber.

    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.
