Abstract: An injector comprises a body, a valve needle slidable within the body and biassed into engagement with a seating by a spring, a fuel supply line for supplying fuel to thrust surfaces provided on the valve needle to apply a force on the valve needle acting against the action of the spring, a drain valve operable to control communication between the supply line and a low pressure drain, a needle control valve controlling the fuel pressure within a control chamber defined, in part, by a surface of the valve needle or a component carried thereby oriented such that when high pressure fuel is applied to the control chamber, a force is applied to the valve needle in a direction assisting the spring, wherein the drain valve and the needle control valve are controlled by an electromagnetic actuator arrangement including a single armature, the needle control valve and the surface of the valve needle or component carried thereby defining part of the control chamber being of dimensions such that the needle control valve is substantially pressure balanced at all times.
