Fuel injection nozzle and method of manufacture

An injection nozzle (10) for use in a fuel injector for an internal combustion engine, the injection nozzle comprising:

• an inner valve needle (26) which is engageable with an inner valve seating (24, 58) to control fuel delivery through one or more first nozzle outlets (14) and operable by means of an actuator to move away from the inner valve seating (24, 58),
• an outer valve (28) which is engageable with an outer valve seating (24, 70) to control fuel delivery through one or more second nozzle outlets (16), wherein the outer valve (28) is provided with a valve bore (36) within which at least a part (26a) of the inner valve needle (26) is received, and
• the inner valve needle (26) having a region (48) which cooperates with a region (46) of the outer valve (28) in circumstances in which the inner valve needle (26) is moved away from the inner valve seating (24, 58) through an amount exceeding a predetermined threshold amount (D), thereby to cause the outer valve (28) to lift away from the outer valve seating (24, 70) together with the inner valve needle (26), and where the regions (46, 48) remain disengaged when the inner valve needle (26) is moved away from the inner valve seating (24, 58) through an amount less than the predetermined threshold amount (D).
