Definitions

  • a first sealing element is arranged radially between the filter element and the inner surface of the valve body and a second sealing element is arranged radially between the filter element and the outer surface of the valve needle.
  • the valve assembly 80 comprises an inlet tube 2. Furthermore, the valve assembly 80 comprises a valve body 4.
  • the valve body 4 has a central longitudinal axis L and a cavity 8.
  • the cavity 8 takes in a valve needle 10.
  • the valve needle 10 has an outer surface 12.
  • the cavity 8 of the valve body 4 forms an inner surface 18.
  • the valve needle 10 In a closing position of the valve needle 10, it sealingly rests on a seat body 26, by this preventing a fluid flow through at least one injection nozzle 24.
  • the injection nozzle 24 may be, for example, an injection hole. However, it may also be of some other type suitable for dosing fluid.
  • the seat body 26 may be made in one part with the valve body 4 or be a separate part.
  • the injection valve 82 is provided with an actuator unit 30 that comprises preferably an electromagnetic actuator with an armature 32 and a coil 36.
  • the armature 32 is coupled to the valve needle 10.
  • the inlet tube 2, the armature 32 and a housing 38 are forming an electromagnetic circuit.
  • the actuator unit 30 may, however, also comprise another type of actuator, which is known to persons skilled in the art for that purpose.
  • Such an actuator may be, for example, a piezoelectric actuator.
