Patent number: 9637418Abstract: In a method for preparing an ester from an hydroxybenzoic acid and a fatty alcohol for use in a binder system for powder injection molding, transesterification of an ester of the hydroxybenzoic acid and a low alcohol using the fatty alcohol is carried out, the fatty alcohol and the ester of the hydroxybenzoic acid and the low alcohol forming a reaction mixture and being used in an essentially equimolar ratio. The transesterification is carried out at a temperature at which the ester of the hydroxybenzoic acid and the low alcohol and the fatty alcohol are present as a homogeneous melt. The binder system for a powder injection molding contains 80 to 98 wt. % of a metal powder and/or a ceramic powder and 1 to 19 wt. % of a polymeric binder component, and 1 to 19 wt. % of at least one ester prepared by the transesterification.Type: GrantFiled: November 25, 2009Date of Patent: May 2, 2017Assignee: ROBERT BOSCH GMBHInventors: Wilfried Aichele, Jochen Rager, Klaus Czerwinski, Eberhard Grath, Josef Arnold, Eva Weisser

Publication number: 20150136879Abstract: The invention relates to a fuel injector having an electromagnet 2 which contains a magnet core 6 and a coil 7 and which further has an armature 9 that is guided on an armature pin 8. The armature pin 8 is guided in a guide sleeve 11 which projects into the electromagnet 2. The fuel injector further has an injector body 4 with at least one injection opening which is introduced into the injector body 4 and which is controlled by an injector needle 5. The aim of the invention is to provide a fuel injector which is functionally improved with respect to the switching times of the fuel injector and the forces that can be generated in the fuel injector while simultaneously simplifying a guide sleeve for an armature pin. This is achieved in that the guide sleeve 11 is integrated into the magnet core 6 and is connected to the magnet core 6 in a formfitting or bonded manner.Type: ApplicationFiled: April 5, 2013Publication date: May 21, 2015Inventors: Jochen Rager, Andreas Buergel, Joachim Fleuren, Bernd Reinsch, Johannes Schmid, Dieter Maier, Helmut Sattmann, David Holzer, Andreas Stimmeder, Dieter Deutsch

Publication number: 20150125306Abstract: A method for producing a connection of at least one rotary component with a central opening to a shaft with a first section along the shaft and a second section on an end face of the shaft includes fixing the shaft at the first section in the central opening of the at least one rotary component by an eccentric arrangement. The fixing of the shaft is such that the shaft is fixed in the radial direction relative to the at least one rotary component. The method also includes fixing the shaft at the second section by press-fitting a ball so that the shaft is secured in the axial direction relative to the at least one rotary component. The fixing steps are carried about by a positive engagement.Type: ApplicationFiled: April 3, 2013Publication date: May 7, 2015Inventors: Johannes Schmid, Bernd Reinsch, Ugur Kisa, Andreas Burghardt, Jochen Rager, Bernd Lutz
