Abstract (en)
[origin: EP0978649A2] The nozzle has a nozzle body (12) with a tip (10) with two axially separate rows of injection holes (14,16) and a nozzle needle (20) axially movable in the nozzle body, whereby a conical surface (22) on the needle tip selectively frees and blocks the fuel path to the injection holes. A protruding insertion body (30) on the needle tip moves axially w.r.t.. the needle. In the closed state the conical surface is in contact with the first, upper row (14) of injection holes on the inside of the tip and a wedge body (32) is in contact with the inside of the tip between the rows of holes. After raising the conical surface to free the fuel path to the first row the wedge body frees the fuel path to the second, lower row (16) of holes.
