  • Patent number: 9637418
    Abstract: 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.

  • Publication number: 20150136879
    Abstract: 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.

  • Publication number: 20150125306
    Abstract: 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.

  • Patent number: 8784625
    Abstract: A sensor element having a layered construction and configured to detect a physical property of a gas or a liquid includes a functional component situated in the interior, which functional component is connected electrically to a conductor element, which conductor element extends up to the outer surface or up into the surroundings of the sensor element. The sensor element has at least one sealing element which adjoins the functional component and/or the conductor element. The conductor element and the at least one sealing element are configured to be gas-tight at least regionally in the interior of the sensor element and are situated in such a way that the functional component is separated gas-tight from the surroundings of the sensor element.

    Abstract: A turbine wheel for a continuous-flow machine includes a centrally arranged hub with circumferentially arranged blades and a pressure equalizing channel. The hub is configured to enclose a cavity, and a resulting principle axis of inertia of the turbine wheel coincides with an axis of rotation of the turbine wheel. The pressure equalizing channel is configured to fluidically connect the cavity to at least one axial end face of the hub and to an environment of the turbine wheel. A diameter of the pressure equalizing channel is smaller than a diameter of the cavity. In one embodiment, the turbine wheel is for an exhaust gas turbocharger.
