摘要： A fuel injection nozzle for internal combustion engines having a nozzle body with a valve seat disposed on a side of the combustion chamber of the internal combustion engine and an outwardly opening needle valve with a closing head that has a closing cone that cooperates with the valve seat. At least one outwardly oriented injection hole is disposed in the closing head that is supplied with fuel via a supply conduit from a pressure chamber. The supply conduit is oriented axially with respect to the injection hole and changes over into this injection hole in a funnel shape. Its width corresponds approximately to the length of the injection hole. The injection hole and supply conduit extend at an acute angle a to the longitudinal axis of the closing head that is adapted to the combustion chamber of the internal combustion engine. The intake of the supply conduit is located in a face end of the closing head remote from the end on the side of the combustion chamber.
