  • Patent number: 12358011
    Abstract: A fuel injector retention arrangement for connecting a fuel injector with a fuel rail comprises a fuel injector receiving cup having a fuel rail end in connection with a fuel rail and a fuel injector insertion end into which a fuel injector is insertable and connecting pins, the connecting pins being insertable into the receiving cup in such a manner, that a longitudinal axis of the connecting pins is situated in a first plane, which is oriented perpendicularly to a longitudinal axis of the receiving cup. The connecting pins are arranged in apertures of the receiving cup. A longitudinal axis of the apertures and the longitudinal axis of the connecting pins are aligned with each other. The apertures have an insertion end into which the connecting pins are insertable and a shoulder forming an axial stop for the connecting pins at a second end of the apertures. The apertures have a service opening which is arranged between the shoulder of the apertures and an outside surface of the receiving cup.

  • Patent number: 12031509
    Abstract: A fuel injector assembly includes a valve housing, a valve stem that is disposed in the valve housing, a magnetic coil that surrounds the valve housing and is used to displace the valve stem within the valve housing, and a terminal blade. The terminal blade includes a bus bar that provides an electrical connection between the magnetic coil and an external connector. In addition, the terminal blade includes a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end. The clip includes a sacrificial portion that is configured to part, for example by dissolving, when the terminal blade undergoes an overmolding process. As a result of the overmolding process, the clip is separated into multiple, spaced portions.
