ABSTRACT:
A fuel injection nozzle comprises a valve member which is biased into contact with a seating by a spring supported on a spring abutment having an integral extension which projects through an aperture in the end face of a holder which carries a nozzle body in which the valve member is located. The valve member is in engagement with the extension. A sleeve surrounds the valve member and is slidable in the body and is engageable with the extension. The valve member and the sleeve move together against the action of the spring under the action of fuel pressure to allow fuel flow to an outlet. The movement of the sleeve is arrested by a stop surface defined by the end face of the holder. The continued movement of the valve member being under the action of the fuel pressure acting on the valve member alone, until its movement is arrested by a stop.
