Abstract
A fuel injector for use in an internal combustion engine comprises a first valve member and a second valve member, an injection control chamber for fuel, and a set of nozzle outlets; wherein actuation of the second valve member controls the fuel pressure within the injection control chamber, and actuation of the first valve member is regulated by the fuel pressure within the injection control chamber; and wherein the fuel injector is arranged such that actuation of the second valve member establishes a fuel flow path between the injection control chamber and the set of nozzle outlets. The first valve member may be provided with a first valve bore within which the second valve member is received. An injection nozzle and a method of operating a fuel injector are also described.
