Definitions

  • DE 196 50 865 A1 refers to a solenoid valve for controlling the fuel pressure in a control chamber of an injection valve, such as a common rail high-pressure accumulator injection system. Via the fuel pressure in the control chamber, a stroke movement of a valve piston is controlled, with which an injection opening of the injection valve is opened or closed.
  • the solenoid valve comprises an electromagnet, a movable armature and a valve member which is moved with the armature and acted upon by a valve closing spring in the closing direction and which cooperates with the valve seat of the solenoid valve and thus controls the fuel drain from the control chamber.
  • a screw connection is realized by means of a union nut, which connects a nozzle body, a resting on this throttle plate and a valve plate of a fuel injector with the holding body of the fuel injector, see for example GB 2024315 A. It is initially of secondary importance, whether the fuel injector is actuated by means of a piezoelectric actuator or by means of a solenoid valve.
  • a sealing ring which is preferably made of PTFE, is used to achieve a seal of the low pressure area of the fuel injector to the outside.

  • the Arretiersegmente which is preferably shown as a separate, circumferentially divided formed locking tongue, a defined locking force can be generated.
  • the height of the axial force introduced into the sealing dressing depends on a height difference between the bearing surface of the nozzle body and locking lugs in combination with the rigidity of the resilient region.
  • sleeve-shaped locking element a circumferential position orientation of the previously used nozzle lock nut, which affects the assembly time low.
  • connection between a nozzle body and associated components as well as the holding body of the fuel injector, which is proposed by the sleeve-shaped locking element proposed by the invention, can also be opened again
  • fixing pins Due to the avoidance of a relative movement in the circumferential direction by the elimination of the screw and the risk of shearing is omitted for fixing pins, which may be required for correct installation of the valve and the throttle plate. If, on the other hand, the valve plate and the throttle plate are oriented in the correct position relative to one another, the use of fixing pins can be completely dispensed with.
  • Low pressure seals are integrated into the nozzle retaining nut, so that previously used, preferably manufactured as a PTFE sealing rings for low pressure sealing can be omitted.
