ABSTRACT:
The invention relates to a fuel injection nozzle, in which at least two levers are disposed between the valve needle and the spring support plate of the closure spring, which levers are supported with one end on the housing and the other end on the valve needle, these levers being supported in the middle region on the spring support plate, thereby permitting a certain lever path. As a result it is attained that during this first lever path or a first stroke of the valve needle, because of the action of the levers, the closing force exerted by the spring on the valve needle is reduced in accordance with the lever translation. As a result of this intermediate-position control of the needle stroke, with the creation of a pressure step in consequence, cold-start hammering of the engine is avoided, and quieter operation is made possible, as a result of the resulting prolongation of injection time during idling and at partial load.
