Abstract: A fuel injection system is disclosed having a fuel injection nozzle which receives pressurized fuel pulses from a source. The nozzle includes a body having a tubular nozzle body with a longitudinally extending opening extending therethrough. A valve seat is located between the upstream and downstream ends of the longitudinal opening in the valve body for engagement with a valve member to thereby regulate the flow of fuel through the opening. A downstream stop member includes a hollow cylinder with a diametrical member extending across one end. The cylindrical stop member is received over the downstream end of the nozzle body with the diametrically extending member disposed across the downstream end of the longitudinal opening to thereby limit the outward range of movement of the valve member from the opening. As a result, the valve member and the downstream end of the longitudinally extending opening define an annular fuel metering orifice therebetween to regulate the flow of fuel from the nozzle.
