ABSTRACT:
A fuel injection nozzle of the inwardly opening type has a valve member slidable in a bore in a nozzle body which is secured to a holder. The valve member is biased by a first spring into contact with a seating and is movable from the seating by fuel under pressure. An abutment rod is engageable by the valve member after a predetermined movement of the valve member away from the seating. The abutment rod is biased by a second spring housing in an insert mounted in screw thread engagement with a bore in the holder. The rod extends through and is guided by an aperture in the insert and is further guided by guide means removed from the insert. The guide means can be a bush carried by the holder, the coils of the first spring or the valve member.
