Definitions

  • the invention relates to a fuel injection valve for internal combustion engines according to the preamble of claim 1.
  • Such a fuel injection valve is out of DE 10 2008 001 330 A1 the applicant known. It essentially comprises, on the side facing the combustion chamber of the internal combustion engine, a nozzle body accommodated in a housing, in which a nozzle needle is moved up and down.
  • the nozzle needle is at least indirectly axially braced together with the nozzle body by means of a clamping nut against a holding body arranged in the housing.
  • the clamping nut has an internal thread as part of a threaded connection, which cooperates with a corresponding external thread on the holding body and in particular also forms a seal of the housing arranged in the region of the nozzle body fuel, which is meant when operating fuel injection valve under relatively high pressure, here a pressure of more than 1500bar, stands.
  • the present invention seeks to further develop a fuel injection valve for internal combustion engines according to the preamble of claim 1 such that the threaded connection, which connects the clamping nut with the holding body and a seal of the housing after forms on the outside, so educate, that it is particularly dense, especially at relatively high fuel pressures.
  • the invention is based on the idea of designing the threaded connection in such a way that at least two toothing regions with different thread dimensions are present which follow one another axially in the longitudinal direction of the housing. This makes it possible to optimize the respective toothed areas with regard to their specific properties or tasks. In particular, this makes it possible, for example, optimally form a first toothed area with respect to its tightness, while a second toothed area is optimized with respect to the relatively simple mounting of the clamping nut.
  • a thread-free intermediate section is formed between the two toothed regions.
  • This unthreaded intermediate section makes it possible, in particular, to manufacture the two toothing regions on the clamping nut or on the holding body in a relatively simple manner.
  • the axial length of the unthreaded intermediate region corresponds to the axial length of a first toothed region on the clamping nut, which is arranged on the side of the clamping nut facing the holding body.
  • the second toothed region on the side of the clamping nut facing the nozzle body have the smaller thread diameter and a double number of teeth than the first toothed region.
  • the wall thickness of the clamping nut in the second toothed region is greater than in the first toothed region. Due to the increased wall thickness of the clamping nut, the occurring compressive stresses can be absorbed particularly well, or a widening of the clamping nut due to the hydraulic pressure compared to the prior art is reduced, which increases the tightness of the second toothed region.
  • Fig. 1 is a section of a fuel injection valve 100 according to the invention shown, as it is used for injecting fuel in a combustion chamber of an internal combustion engine, not shown, in particular a self-igniting internal combustion engine.
  • the fuel injection valve 100 is part of a so-called common-rail injection system, in which each cylinder of the internal combustion engine, a separate, supplied by a common rail with fuel fuel injection valve 100 is assigned.
  • the injection pressure of the fuel injection valve 100 is preferably more than 1500 bar.
  • the fuel injection valve 100 has a housing 10, which is shown only in regions, in which, inter alia, an injection valve member (not shown), in particular in the form of a nozzle needle, is arranged to be movable up and down.
  • a nozzle body 11 is arranged, which simultaneously forms the combustion chamber of the internal combustion engine facing the end of the fuel injection valve 100.
  • the nozzle body 11 has a step 12 on its outer periphery.
  • a throttle plate 13 is arranged, as well as on the nozzle body 11 side facing the throttle plate 13, a valve plate 14.
  • a holding body 15 of the housing 10 against which the nozzle body eleventh , the throttle plate 13 and the valve plate 14 are axially braced.
  • the axial clamping of the addressed components of the fuel injection valve 100 by means of a clamping nut 18, which has at its end facing the nozzle body 11 at its inner wall a diameter stage 19 which rests flush against the step 12 of the nozzle body 11.
  • the Fig. 1 is formed between the holding body 15 and the clamping nut 18, a threaded connection 20.
  • the threaded connection 20 has a first toothed region 21 on the side facing away from the nozzle body 11 and a second toothed region 22 on the side facing the nozzle body 11.
  • a first toothed region 21 on the side facing away from the nozzle body 11
  • a second toothed region 22 on the side facing the nozzle body 11.
  • the intermediate region 23 is formed in the region of the holding body 15 as a cylindrical portion 17 with a continuous same outer diameter.
  • two sections 24, 25 are formed, each of which is cylindrical, the section 24 facing the first gear section 21 having a larger inner diameter than that of the second gear section 22 facing portion 25.
  • the two portions 24, 25 in about the same length, z. B. each about 2mm, formed.
  • the second toothed region 22 is located near the lower end face 26 of the holding body 15 in the region of the holding body 15 on the side facing the valve plate 14.
  • FIG. 2 to 4 different phases of the assembly process of the clamping nut 18 are shown on the holding body 15.
  • the state is shown in which the first toothed region 21 of the clamping nut 18 is located in the region of the second toothed region 22 of the holding body 15.
  • a gap 27 is formed between the teeth of the second toothed region 22 of the holding body 15.
  • the state is shown in which the first toothed region 21 of the clamping nut 18 in the region of the first toothed region 21 of the holding body 15 arrived. It is essential that at the beginning of the engagement of the thread of the first toothed portion 21 of the clamping nut 18 in the first gear portion of the holding body 15, the output of the winding of the first toothed portion 21 of the clamping nut 18 is still in abutting contact with the second toothed portion 22 of the holding body 15. As a result, the first toothed region 21 of the clamping nut 18 is always in engagement with one of the two toothed regions 21, 22 of the holding body 15, so that slippage or falling through of the clamping nut 18 during assembly on the holding body 15 is avoided.
