  • Publication number: 20020179743
    Abstract: A fuel injection valve with a valve body (1) and a bore (3), embodied as a blind bore, whose bottom face is oriented toward the combustion chamber. A conical valve seat (9), in which at least one injection port (11) is disposed, is embodied on the bottom face. In the bore (3), a pistonlike valve member (5), which is longitudinally displaceable counter to a closing force, is disposed and has a valve member tip (7), which in the closing position of the valve member (5) comes to rest on the valve seat (9). A first conical face (30) and a second conical face (32), disposed toward the combustion chamber toward the first conical face, are embodied on the valve member tip (7), and the cone angle (&agr;) of the first conical face (30) is smaller than the cone angle (&ggr;) of the valve seat (9), which in turn is smaller than the cone angle (&bgr;) of the second conical face (32).
