Abstract

A nozzle needle (2) slidable in a nozzle body (1) terminates in a pintle (4) slidable in a central outlet bore (5). A pressure space (7) is arranged between the valve seat (3) and the pintle (4). The pintle (4) has a longitudinal bore (8) and a transverse port or bore (9) communicating therewith, and an annular gap (6) between the wall of the central bore (5) and the pintle (4) provides an atomised spray at low speeds and/or loads. The transverse port or bore (9) terminates within the central bore (5) when the nozzle needle is closed and connects the space (7) with the bore (4) after a predetermined lift of the nozzle needle (2) to provide a compact fuel jet at higher speeds and/or loads. The pintle (4) extends over substantially the full length of the central outlet bore (5) when the nozzle needle (2) is fully open, thereby preventing an increase in atomised spray. <IMAGE>
