ABSTRACT:
A fuel injection nozzle for internal combustion engines, having a valve needle loaded with a closing spring and having a damping device which damps the end stroke (h.sub.2), leading into the fully open position of the valve needle, in accordance with the number of strokes and/or stroke length of the valve needle or with the quantity of fuel put through per injection event. The valve needle is coupled with a second damping device, which in partial-load and full-load operation also, at least intermittently, damps the initial stroke (h.sub.1), leading out of the closing position, of the valve needle. As a result it is attained that for a wide range of the performance graph, the ratio of the injection quantity to the duration of injection can be optimized in terms of the fuel consumption and emission of toxic substances, without having to accept increased combustion noise in the critical ranges.
