摘要： A fuel injector includes a tubular injector body which has an open, upper end and defines an axial fuel passage. A solenoid actuator assembly is disposed in the injector body and includes a spool-like bobbin with a central through-bore and a wound wire coil supported thereon. A magnetic circuit pole subassembly includes a fuel tube, a valve guide, and a pole piece. The fuel tube has a tubular portion and a lower circular flange portion radially extending from a lower terminal end of the tubular portion to contact the open, upper end of the injector body. The nonmagnetic valve guide has a guide cylindrical portion, extending axially downward through the central throughbore and is closely encircled by the bobbin, and a guide circular flange portion radially extending from an upper end of the guide cylindrical portion and mating with the lower circular flange portion of the fuel tube. The pole piece is configured as a constant section cylinder to be received by the fuel tube tubular portion and the guide cylindrical portion. A valve armature is disposed within the injector body downstream of the pole piece where upon energization of the solenoid actuator assembly, the injector body, fuel tube, pole piece, and armature conduct a magnetic circuit to axially draw the valve armature permitting fuel injection.

摘要： A fuel injector for discharging fuel to an internal combustion engine is disclosed. The injector has a nozzle body with an annular valve seat surrounding a fuel discharge opening. A valve member is disposed in the internal cylindrical cavity and is moveable between a first, sealing position relative to the valve seat and a second, open position off of the seat. The valve member is guided in its movement, with respect to the valve seat by a valve guide member disposed in the nozzle, closely adjacent the annular valve seat. The valve guide member includes a disc shaped member having an outer perimeter which is configured for placement within the nozzle body and a tubular central portion which defines a central, valve guide opening. The valve guide opening extends through the tubular central portion to open adjacent the annular valve seat and is configured for circumjacent disposition relative to the valve member to guide movement of the valve. Fuel openings extend through the valve guide and are disposed circumferentially about the valve guiding central opening to conduct fuel around the valve guide member.

摘要： An engine fuel injector includes an internal fuel passage in which pressure waves can develop upon opening and closing of an injection valve. A fuel pressure damper is associated with the fuel passage and operates to vary the internal volume of the fuel passage in a manner to reduce the amplitude of pressure variations and pressure waves in the fuel passage. A variety of fuel pressure damper embodiments are disclosed.
