Abstract
A fuel injection nozzle for internal combustion engines that has a nozzle body with a valve seat disposed on the combustion chamber end and an outwardly-opening valve needle with a closing head, which has a closing cone that works together with the closing valve seat. At least one injection port is disposed in the closing head at an angle with respect to the axis of reciprocation of the valve needle, and is opened by a control edge on the nozzle body depending on the inlet pressure of the fuel. In order to minimize any deflection of the injection stream flowing out of the injection port relative to the alignment of the injection port, the port is divided into at least two parallel conduits, which are separated from each other by a dividing wall and which upon the opening stroke of the valve needle are unblocked one after the other by the control edge.
