Abstract
An injection nozzle () for an internal combustion engine, the injection nozzle () including a nozzle body () provided with a bore () defining a valve seating surface, and having a first nozzle outlet and a second nozzle outlet, a first delivery chamber upstream of said nozzle outlets, an outer valve member, moveable within the bore () and itself provided with an axial bore (), wherein the outer valve member is engageable with an outer valve seat defined by the valve seating surface so as to control fuel flow from a first delivery chamber to at least the first nozzle outlet when the outer valve member lifts from its seat. The injection nozzle () also includes an inner valve member, moveable within the axial bore () and including first and second seating lines spaced apart axially from each other, both seating lines being engageable with an inner valve seat defined by the valve seating surface so as to control fuel flow from a second delivery chamber to the second nozzle outlet when the inner valve member lifts from inner valve seat. The inner valve member defines, at least in part, a flow path including an axial passage provided in the inner valve needle such that fuel may flow from the first delivery chamber to the second delivery chamber.
