Magnetic assembly for actuating injection valve used for injecting e.g. fuel into combustion chamber of internal combustion engine of motor vehicle, has armature whose stroke movement produces stroke movement of inner pole

摘要

The assembly has a strokingly movable armature (2) i.e. plunger, interacting with a magnetic coil (1), and executing a stroke movement in a direction of an inner pole (4) against resilient force of a spring (3) during energizing the coil. The pole is strokingly movably received in a hole (5) i.e. stepped hole, of a housing part (6). The pole is hydraulically and/or mechanically coupled with the armature so that the armature stroke movement produces a stroke movement of the pole. The pole is subjected with the force in a direction of an annular stroke stopper (7) e.g. annular sealing body. An independent claim is also included for an injection valve.
