Patents by Inventor Tilla Haubold

Tilla Haubold has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20160297008
    Abstract: A one-piece component includes a first subregion made of a base material, and a second subregion made of the base material as binder with intercalated hard material particles, the second subregion being injection-molded onto the first subregion by means of MIM injection molding, so that an integral connection is formed between the first subregion and the second subregion. Furthermore, a method for producing the one-piece component by means of MIM injection molding is described.
    Type: Application

  • Patent number: 9394867
    Abstract: A fuel injection valve for injecting fuel includes: a coil, an internal pole, a valve sleeve, and a magnetic separating element, where the valve sleeve and the magnetic separating element are embodied in one piece as a powder injection-molded component, and the valve sleeve forms a magnetic region and the magnetic separating element forms a non-magnetic region, which are intermaterially joined to one another.

  • Patent number: 8245402
    Abstract: The method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, is characterized in that the following method steps are used: a) providing a sheet metal strip made of a magnetic or magnetizable material, b) introducing an additive into a middle area of the sheet metal strip and fusing there for forming a non-magnetizable structure, c) cutting the sheet metal strip into a sheet metal piece of desired width, d) deforming the sheet metal piece into a sleeve shape, e) mutual fastening of the cut edges now facing each other and running in the longitudinal direction of the sleeve for forming a sleeve blank, f) final machining of the sleeve blank until a desired geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines.
