Abstract: A fuel injection valve for internal combustion engines with a valve needle which is adapted to be opened by the fuel pressure against the thrust of a first spring. The valve needle is in a parallel arrangement to the first spring additionally placed under load by the fuel to which end a buffer chamber preceding that end face of the nozzle needle which is located opposite the conical nozzle tip, communicates through a first nozzle with the fuel pressure line. The buffer chamber communicates through a second throttle with a fuel leakage line while the connecting line to the leakage line is controlled by a spring loaded reversing valve, as soon as the valve needle opens. This reversing valve opens the connection between the first connecting line leading to the buffer chamber and the fuel pressure line and closes the second connecting line normally connecting the buffer chamber with the fuel leakage line.
