20140072404 | BLADE WHEEL FOR A CONTINUOUS-FLOW MACHINE AND METHOD FOR PRODUCING A TURBINE WHEEL FOR A CONTINUOUS-FLOW MACHINE - 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. | 03-13-2014 |
20150125306 | Method for Connecting a Shaft to a Rotary Component and Turbocharger Shaft Produced by said Method - 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. | 05-07-2015 |
20150136879 | FUEL INJECTOR - The invention relates to a fuel injector having an electromagnet | 05-21-2015 |
20150176416 | Method for Producing a Rotor Wheel and a Rotor - A method for producing a component, in particular a rotor wheel, includes positioning a main body, a fusion-weldable attachment layer, and a barrier layer. The main body has a first alloy in an attachment region. The fusion-weldable attachment layer is positioned in the attachment region of the main body and has a second alloy which differs from the first alloy. The barrier layer is positioned between the main body and the fusion-weldable attachment layer. The barrier layer is configured to prevent a reaction of the first alloy of the main body with the second alloy of the fusion-weldable attachment layer during a thermal treatment. The method further includes heating the main body, the barrier layer, and the fusion-weldable attachment layer to connect the main body, the barrier layer, and the fusion-weldable attachment layer to one another. | 06-25-2015 |
