Abstract
An injector arrangement is disclosed which comprises a valve needle urged into engagement with a seating under the action of the pressure of fuel within a control chamber. A needle control valve controls communication between a source of fuel at high pressure and the control chamber, and also between the control chamber and a low pressure drain. The needle control valve includes a valve member including an end which is engageable with a surface extending in a plane normal to the axis of the valve member to close a port communicating with the low pressure drain.
