Definitions

  • the invention is based on a magnetic coil of the type of claim 1.
  • a magnetic coil of the type of claim 1. takes place Use with a distributor fuel injection pump according to DE-A1-43 39 948.
  • the magnetic coil provided there is part a solenoid valve of a distributor fuel injection pump and exposed to fuel during operation.
  • the well-known Magnetic coil is on a winding body made of insulating material applied and subsequently by an additional Plastic pad closed.
  • the winding body from Plastic has extensions made of insulating material, inside which the contact connections of the solenoid are guided. The areas of the contact connections thus surrounded by insulating material are through the openings in the bottom of the case passed through and are lying on the outside through seals sealed a closure plate, the rest of the fuel-carrying space after the fuel injection pump seals outside.
  • the object of the invention is the magnetic coil within the Position the housing exactly. This task will according to the invention by the subject matter of patent claim 1 solved. Further advantageous embodiments of the invention are the subject of the subclaims.
  • the invention is characterized in that that in a simple way an accurate positioning of the Magnetic coil inside the pot-shaped housing is realized and a high density in a simple manner Completion of the live parts of the solenoid is achieved to the outside.
  • the solenoid coincides with that Contacting the walls of the surrounding pot-shaped housing intensively in this case.
  • the solenoid is beyond securely fixed in this housing and it is an exact Assignment to a magnet armature of the magnet coil can be achieved. In doing so, the openings are required to the contact connections from the exposed to the fuel Leading space outwards, intensively through the extrusion coating the magnetic coil filled with insulating material and sealed.
  • Positioning of the solenoid is within the surrounding one Isolierstoffes a third opening in the pot-shaped Provided housing through which a support member can be inserted. This serves together with the contact connections of the solenoid to fix the position. That way it is possible while encapsulating the solenoid with insulating material to maintain the position of the solenoid exactly. In order to are also the electrical values and the magnetic forces that act on an anchor, exactly observable.
  • the arrangement of the third opening, through which a rod-shaped part can be inserted and the position the contact connections are selected so that a stable three-point bearing the coil during the spraying process becomes.
  • a measuring point outside the Pot-shaped part created, which ensures that the inner area of the pot-shaped housing with the extrusion coating the solenoid is completely filled, and that then removal of the rod-shaped part is still possible during the spraying process, so that the third opening and the coil is made at this point with insulating material.
  • This Spigot needs when using the solenoid in an application according to the prior art none Connection of fuel-carrying rooms to non-fuel-carrying rooms Spaces or surroundings, so that at this then also no sealing must be done, as with the Contact connections that must have such a connection.

Further is a third between the bottom and the injection mold Space provided within through a feed opening in the rod-shaped part for positioning the wall of the injection mold the solenoid is insertable and through the third Opening in the bottom of the housing can be passed. Within These three rooms become the contact connections during the spraying process overmoulded and also the rod-shaped part initially molded. Then at the end of the injection process after withdrawing the rod-shaped part this third room completely filled.
  • the solenoid coil is advantageously used in a distributor injection pump used according to claim 6. at the seal required there between fuel-carrying Parts of the fuel injection pump and fuel-free It is important to take into account that, a hundred percent Sealing the openings in the bottom of the pot-shaped Plastic injection molding is not possible, because of the different temperature expansions of Insulating material and metal an initially existing density Adhesion between plastic and metallic housing is present, then undergoes a replacement in operation. For this reason, it is necessary that the outside leading contact connections in addition to the component be sealed, otherwise the fuel-carrying Rooms of the distributor injection pump are closed.
  • This component according to claim 7 has a receptacle, which at the third opening of the pot-shaped housing completely encloses the insulating material protruding part. This means that there is no connection at this point between fuel-carrying parts and fuel-free Divide the distributor injection pump so that a third Sealing point is omitted here.
  • a third sealing point should be used be created because between the rod-shaped part and plastic extrusion possibly a fuel supplier Gap could result in the tightness of the coil endangered, or because, on the other hand, a passage also this third place provided by the component would have to be sealed, which passage is then sealed should be. With the tight, little space available design of distributor injection pumps thus it enables a compact design without additional Achieve mounting space for seals.
