  • Fuel injector device and method of producing the same
    Patent number: 5109823
    Abstract: A fuel injector device has a fuel swirling element disposed upstream of a valve seat and capable of imparting a swirling force to a fuel supplied thereto, a fuel injection nozzle orifice disposed downstream of the valve seat, and a fuel distributing adapter disposed downstream of the fuel injection nozzle orifice and capable of distributing the flow of the fuel injected by the fuel injection nozzle orifice in two directions. The adapter has an axial fuel passage having a fuel inlet of a diameter greater than that of the injection orifice and an outlet end of a substantially "8"-shape having a minimum diameter smaller than that of the inlet end. The adapter can be formed by preparing a blank having an axial fuel passage and then conducting a plastic work by a punch press on an end face of the blank so as to restrict the outlet end of the fuel passage.
