Abstract
A fuel injection nozzle has a body in which is formed a bore at one end of which is a seating. Outlet orifices extend from the bore and located in the bore is a valve member shaped at one end to engage the seating and spring biased into engagement with the seating to prevent fuel flow through the orifices. The initial movement of the valve member away from the seating is limited and during this limited movement the fuel flow through the orifices is limited by an annular clearance defined by axially extending cylindrical surfaces formed by the wall of the bore and the valve member.
