ABSTRACT:
An injector nozzle for a fuel injected internal combustion engine, said injector nozzle including a port (5) having a valve seat surface (15) and a valve member (3) having a seating surface (17), said valve member (3) being movable relative to the port (5) to respectively provide a nozzle passage (6) between the valve seat surface (15) and the seating surface (15) for the delivery of fuel therethrough or sealed contact therebetween to prevent said delivery of fuel, the valve member (3) including an outer valve surface (18) located adjacent the seating surface and external to the port, wherein a sharp edge (25) is provided on the valve member (3) at the transition between the seating surface (17) and the outer valve surface (18) thereby for controlling the formation of deposits at or adjacent an exit of the nozzle passage (6).
