摘要： 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.

摘要： A fuel system including a fuel nozzle is disclosed. The fuel nozzle is adapted to receive pulsed pressurized fuel from a source and includes a valve seat assembly having a valve seat body with a longitudinally extending passage. The passage of the valve seat body has a valve seat extending thereabout and interfaces with a downstream opening valve element which is disposed within the longitudinally extending passage and operates to move into and out of sealing engagement with the valve seat to regulate the flow of pressurized fuel though the passage. The valve element has a spherically configured upstream surface for sealing engagement with the valve seat which includes an annular drag groove extending thereabout. The drag groove functions to increase viscous drag force, in the downstream opening direction, which is imparted on the valve element by fuel flow over the spherical upstream surface. The nozzle also has an annular, fuel directing orifice disc which is disposed downstream of the valve seat. The orifice disc includes fuel directing orifices which extend therethrough from a first, upstream side to a second downstream side. The annular fuel directing orifice disc limits downstream movement of the valve member and directs fuel through the orifices into a desired fuel pattern.
