ABSTRACT:
A fuel injection nozzle of the two stage lift type has a nozzle body containing the valve member of the nozzle and a holder which are spaced apart by a distance piece. A first spring acts on the valve member and a second spring is operative on the valve member after the latter has moved a predetermined distance away from the valve seating. The second spring is engaged by a spring abutment which in the closed position of the valve member engages the adjacent face of the distance piece and the end of the valve member lies flush with the valve body. A push piece is interposed between the valve member and the spring abutment and the extent of movement of the valve member before the second spring is brought into operation is determined by maching the push piece and/or the distance piece.
