Definitions

  • an injection valve which comprises an actuator module with a cavity and an actuator unit.
  • the injection valve further comprises a fluid module, being disposed at least partially within the cavity of the actuator module and comprising a housing and a valve needle.
  • the valve needle is disposed in the housing and is actuatable by the actuator unit.
  • the valve needle is operable to prevent a fluid injection in a closing position and permit the fluid injection in further positions at a fluid module end.
  • the actuator module is adhered to the fluid module via a metal adhesive, which is arranged between a surface of the housing of the fluid module and a surface of a wall of the cavity of the actuator module.
  • the fluid module end may for example associate to an intake manifold of the internal combustion engine.
  • the injection valve may for example be a low pressure injection valve for dosing gasoline into the intake manifold.
  • FIG. 1 an injection valve
  • An injection valve 18 ( FIG. 1 ), that is in particular suitable for dosing fuel into an intake manifold, comprises a fluid module 2 and an actuator module 4 .
  • the fluid module 2 comprises a housing 24 and a valve needle 8 .
  • the valve needle 8 is disposed within the housing 24 and is operable to prevent a fluid injection into the intake manifold in a closing position and permit the fluid injection into the intake manifold in further positions.
  • a first fluid module end 6 is associated to the intake manifold, where the fluid is dosed into.
  • a second opposite fluid module end 7 may be hydraulically coupled to a fluid rail, in which fluid is reserved under a predetermined pressure.
  • the actuator module 4 comprises a cavity 20 ( FIG. 2 ) in which the fluid module 2 is at least partially disposed.
  • the actuator module 4 further comprises an actuator unit 14 which is for example a magnetic coil which is operable to magnetically actuate the valve needle 8 to move along a longitudinal axis L of the injection valve 18 . Also other accomplishments of the actuator unit 14 are possible.
  • the actuator module 4 comprises an electrical connector 10 which is electrically coupled to the actuator unit 14 to electrically actuate the actuator unit 14 .
  • the electrical connector 10 is electrically coupled to the actuator unit 14 via one or more wires, which are routed through an actuator housing of the actuator module 4 to the actuator unit 14 .
  • FIG. 2 depicts the fluid module 2 and the actuator module 4 of the injection valve 18 .
  • FIG. 2 further depicts a metal adhesive 16 which is applied on a surface of the housing 24 of the fluid module 2 .
  • the metal adhesive 16 is applied sectionally on a predetermined area of the surface of the housing 24 of the fluid module 2 which is associated to the first fluid module end 6 of the fluid module 2 .
  • the metal adhesive 16 is applied completely around the housing 24 of the fluid module 2 .
  • the metal adhesive 16 is at least sectionally applied on an area of a surface of the wall of the cavity 20 of the actuator module 4 .
  • the metal adhesive 16 is preferably liquid if it is not hardened and is preferably applied on the particular surface in liquid form.
  • the actuator module 4 After applying the metal adhesive 16 the actuator module 4 is put over the fluid module 2 , whereas the metal adhesive 16 is in contact with the surface of the housing of the fluid module 2 and the surface of the wall of the cavity 20 of the actuator module 4 . During this step the metal adhesive 16 is still liquid. After putting the actuator module 4 over the fluid module 2 , the metal adhesive is hardened for a predetermined period of time, for example 5 min.
  • the metal adhesive 16 is arranged or applied on an area of the surface of the housing 24 fluid module 2 and/or on an area of the surface of the wall of the cavity 20 of the actuator module 4 which is located between the electrical connector 10 and the first fluid module end 6 of the fluid module 2 .
  • the fluid permeation path 12 is at least stopped before it runs along the routing of the one or more wires of the electrical connector 10 to the outside combustion engine environment.
  • the use of the metal adhesive 16 contributes to prevent the permeation of moisture between the fluid module 2 and the actuator module 4 may be combined with other facilities to contribute to prevent the permeation of moisture, for example the use of a sealing ring between the first fluid module end 6 and the actuator unit 14 . Basically the use of the metal adhesive 16 is sufficient to prevent the permeation path 12 between the fluid module 2 and the actuator module 4 .
