ABSTRACT:
A fuel injection nozzle includes a fuel pressure actuated valve member which is biased by a first spring into engagement with a seating. A pre lift stop is engaged by a surface which moves with the valve member after a predetermined movement of the valve member away from the seating. The lift stop is movable against the action of a second spring to allow continued movement of the valve member. The lift stop position is determined by a yieldable abutment which during the closing movement of the valve member towards the seating, yields under the action of the inertia of the pre lift stop to assist the closing movement of the valve member.
