Abstract
A fuel injector comprising a nozzle body defining a bore within which an outer valve member is slidable, the outer valve member being engageable with a first seating to control fuel injection from a first outlet opening provided in a nozzle body. The outer valve member is provided with a through bore within which an inner valve member is slidable, the inner valve member being engageable with a second seating to control fuel injection through a second outlet opening provided in the nozzle body. The fuel injector further comprises first and second control chambers for fuel whereby, in use, movement of the inner and outer valve members away from their respective seatings is controlled by controlling fuel pressure within the first and second control chambers so as to permit fuel delivery from a selected outlet opening.
