Abstract:
An injection nozzle for injecting fuel into a combustion chamber of an internal combustion engine comprises a nozzle body having a bore for receiving fuel from a supply line for pressurized fuel, an outlet from the bore for delivering fuel to the combustion chamber, in use, and a valve needle defining a needle axis and being slidable within the bore. The needle comprises a needle guide portion arranged to guide the needle within the bore. The injection nozzle further comprises a restriction within the bore for restricting fuel flow through the bore, and a restrictive element moveable with the needle and located upstream of the needle guide portion. At least a part of a downstream side of the restrictive element comprises a bevelled surface that extends to a peripheral edge of the restrictive element, the bevelled surface being non-perpendicular to the needle axis.
