Definitions

  • Injection systems for injecting fuel are used to supply fuel to the combustion chambers of ner internal combustion engines.
  • Corresponding injectors generally have a solenoid valve, an armature stroke of such a solenoid valve having to be set precisely when fitting corresponding injectors, since the injector dynamics are significantly influenced by the armature stroke. For example, with a fixed activation period of a solenoid of the solenoid valve, the amount of fuel injected depends on the armature stroke.
  • the armature stroke is set via setting rings which determine the axial position of a corresponding armature stop.
  • the opening of a nozzle of the injector and thus the amount of fuel injected is determined via the armature or the movement of the armature in the axial direction and its axial (end) position.
  • a magnet group is then screwed together with the setting ring dimensioned according to the calculation to the injector body and then the armature stroke is measured in the screwed or tensioned state.
  • Tolerances in the micrometer range can be tolerated for the armature stroke in order to ensure reproducible injector behavior. Due to the only slight tolerance deviations allowed, the anchor stroke after an initial assembly as described above is not always within the tolerance values.
  • the magnet group In order to ensure the setting of the armature stroke within the narrow tolerance values, the magnet group has to be completely dismantled and the armature stroke has to be reset by choosing a setting ring of a different dimension. This process may even have to be repeated several times until an acceptable tolerance of the anchor stroke can be achieved. This process leads to high costs in production.
  • the present invention has in particular the object of providing a device for adjusting an armature stroke of an armature of a solenoid valve, in particular for use in connection with injectors in injection systems, by means of which, even after initial assembly, the possibility of adjusting the armature stroke means that it cannot be dismantled again if it is set incorrectly Anchor stroke is required, which can reduce manufacturing costs in manufacturing.

  • the position of a stop sleeve can be adjusted via the setting of the adjusting element, which is arranged in an axial guide and can be adjusted in its axial position with respect to a main body of the solenoid valve. Due to its set axial position, the stop sleeve forms a stop for the armature to limit the armature stroke in an axial direction of the solenoid valve.
  • the adjustment of the axial position of the stop sleeve with respect to the main body of the solenoid valve via the adjusting element takes place in such a way that a first threaded section of the adjusting element engages in a corresponding first threaded section of the stop sleeve with the same thread pitch, and that a second threaded section of the adjusting element engages in one corresponding second threaded section of the main body engages with the same thread pitch.

  • the axial guidance of the stop sleeve can either be arranged in the magnet, but it is also possible for the axial guidance of the stop sleeve to be arranged in the main body. Depending on the given installation situation, an efficient and reliable axial guidance of the stop sleeve is possible, which serves the accuracy and reliability of the setting of the anchor stroke.
