ABSTRACT:
A fuel injection nozzle for supplying fuel to an internal combustion engine includes a valve member which at one end is of reduced diameter and mounts a spring abutment and at its other end is engageable with a seating to prevent flow of fuel from an inlet to an outlet. The valve member is slidable in a sleeve which is also slidable in a nozzle body secured to a holder. A spring is located in a chamber in the holder and the reduced diameter portion of the valve member extends into the chamber. A tubular push piece surrounds the reduced diameter portion to transmit the force developed on the sleeve by the fuel pressure, to the spring abutment. The movement of the sleeve is limited by the engagement of a flange on the push piece with the end face of the holder and the movement of the valve member is limited by the engagement of a step defined on the valve member with the end of the push piece.
