A fuel injector () including a fuel injector housing (), a valve seat () formed at one end of the fuel injector housing, and a valve body () disposed in the fuel injector housing and operable to open and close a spray hole () in the valve seat. The valve seat includes a base portion () and insert portion () having spray holes () that is secured to the base portion ().

Fuel injector valve seat assembly including insert locating and retention features

A method for producing an injector which is designed in particular to inject fuel into an induction pipe or directly into a combustion chamber of an internal combustion engine. The method includes providing an injector base element, providing a rod that is insertible into a through hole of the injector base element, producing a negative matrix of a spray orifice element on an axial end of the rod, inserting the rod into the through hole of the injector base element, positioning the negative matrix situated on the rod relative to the injector base element, producing the spray orifice element having at least one spray orifice by applying a galvanization layer on a downstream end, in the injection direction, of the injector base element and on the negative matrix, and removing the rod and the negative matrix.
