Abstract
A fuel injector comprising a nozzle body having a first bore defining first and second seatings and an outer valve member slidable within the first bore and engageable with the first seating to control fuel flow from a first outlet opening located downstream of the first seating. The outer valve member is provided with a through bore and an inner valve member is slidable within the through bore and is engageable with a second seating to control fuel flow from a second outlet opening. The through bore defines a step which is engageable with an enlarged region of the inner valve member, the through bore permitting, during fuel injector assembly, insertion of the inner valve member into the through bore through an end of the through bore remote from the first and second outlet openings. The invention also relates to a method of assembling such a fuel injector.
