ABSTRACT:
A fuel injection nozzle is proposed having a valve needle which opens in the direction of fuel flow and a throttle point controlled in accordance with the stroke of the valve needle which is loaded by at least two closing springs, in order to obtain a distinct pressure jump with respect to the required opening pressure when the throttle point is rendered ineffective. As a result, the throttle point is fully effective during idling and at relatively low partial loads and is only rendered ineffective when the supply of fuel is relatively great.
