Definitions

  • the invention relates to an anchor plate according to the preamble of claim 1 and to a method for producing such an anchor plate.
  • the object underlying the invention is in the manufacturing and cost of To reduce anchor plates and beyond one Optimization of the anchor plates with regard to to achieve functional design.
  • the advantages of the invention consist essentially in the saving of the previously required turning and Milling operations and thus mean a significant one Cost reduction in the manufacture of the speech standing anchor plates.
  • the Application of the MIM injection molding process an almost any design of all structural details, especially the radial recesses, and thus one Functional optimization of the anchor plate all in all.
  • Sintering and / or heat treatment measures can be in addition, the hardness and strength of the anchor plate optimally adapt to the respective application.
  • the flat connector 15 is used to supply power to one Electromagnets with a magnetic core 16, one Solenoid 17 and an anchor bolt 18 (see in particular Fig. 2).
  • the electromagnet 16, 17, 18 is overall using one as a union nut trained chuck 19 on the housing body 11 fixed.
  • the housing body 11 has a housing extension 20, within which a fuel injector (not shown) is arranged.
  • the fuel supply serves a sealing in the housing extension 20 screwed pressure pipe socket 21.
  • the peculiarities of the invention are in Structure, manufacture and design of the anchor plate 25.
  • a preferred embodiment of the anchor plate 25 goes 3 - 5 in particular.
  • the design of the plate-shaped plate part 28 so it is 3 and 4 in particular that the Plate part 28 a total of three in uniform Angular distance of 120 ° to each other radial Has recesses 36, which as an angular Incisions are formed.
  • the opening angle ⁇ of the angular incisions 36 is 90 °.
  • At her radially inner tips 37 go the angular incisions 36 in groove-shaped radial Recesses 38 over that in the bore extension 30th the guide hole passing through the anchor plate 25 27 flow into.
  • Figure 5 makes it clear that the groove-shaped recesses 38 one from the radially outside groove base 39 rising evenly towards the inside have, wherein, as Fig. 3 reveals, the Groove bottom 39 have a rounded cross section can.
