Definitions

  • the invention is based on the preamble of claim 1 from DE-B 1 010 783.
  • This known injection nozzle assembly comprises two clamping shoulders which are arranged in one piece diametrically on the outer circumference and to which a flange with an opening which is adapted to the clamping shoulders is assigned an opening.
  • the injection nozzle is not secured against rotation relative to the cylinder head.
  • Such a rotation lock for an angle-oriented secured injection nozzle comprises the fastening device known from DE-B 2 262 570.
  • This anti-rotation device comprises a closed double-edge formed in the flange, which corresponds to two flats in the free end region of the injection nozzle. To mount the flange on the injection nozzle, the devices of the injection nozzle provided in the free end area must be removed.
  • a non-generic fastening device for an injection nozzle wherein a hollow screw threadable from the free end of the injection nozzle can be screwed to the cylinder head as a union nut, which is arranged via a clamping shoulder arranged in an outer circumferential groove and designed as a spring ring acts on the separately angularly oriented injection nozzle with pretensioning force.
  • the object of the invention is to provide a fastening device for an injection nozzle which is provided with projecting means, in particular in the free or fuel connection-side end region, and which enables a simplified external design of the injection nozzle in the fastening region.
  • the flange has a recess as a recess on one side open edge for corresponding stop surfaces on the injection nozzle and acts on a separate annular or cylindrical clamping element from the injection nozzle, which has a separate in the outer peripheral region of the injection nozzle interchangeable clamping shoulder cooperates.
  • the injection nozzle is provided with an open-edged square Flange also achieved an advantageously simplified assembly.
  • the sealing arrangement of the injection nozzle is supported in particular in the case of relatively rapidly changing, higher power outputs of the internal combustion engine in that the rapidly heated bottom-side cylinder head portion also supports the injection nozzle their clamping shoulder presses against the relatively cool cylindrical or sleeve-shaped clamping element.
  • stud screws advantageously enables the flange to be held separately from the cover holder, for which the stud screws are combined with means for fixing the cover in a noise-isolating manner.
  • Suitable agents for this are known for example from DE-A 2 628 692.
  • a device 1 for fastening an injection nozzle 2 provided with projecting devices in the fuel connection end region to a cylinder head 3, indicated in FIG. 3, of an internal combustion engine (not shown) comprises a flange 4, which acts on the injection nozzle 2 in a prestressed manner by means of screw bolts 5 arranged in the cylinder head 3.
  • the flange 4 has a recess 6, which is designed as a double-sided open edge 7, which, via corresponding stop faces 8 on the injection nozzle 2, serves to hold the angle-oriented holder on the cylinder head 3.
  • the flange 4 acts on a cylindrical clamping element 9 separate from the injection nozzle 2, which is preferably designed as a pressure sleeve 10.
  • this pressure sleeve 10 interacts with a clamping shoulder 11 which can be arranged separately in the outer circumference of the injection nozzle 2 and which is preferably designed as a spring ring 13 arranged in an outer circumferential groove 12 of the injection nozzle 2.
  • the tensioning shoulder 11 or the spring ring 13 is provided in the end region of the injection nozzle 2 on the nozzle side.
  • the injection nozzle 2 which bears tightly against a stop on the cylinder head side, is pressed against the relatively cool pressure sleeve 10, which supports the sealing arrangement.
  • flange 4 is connected to the fixing of a cover 14 for the cylinder head 3 serving as studs 15 as a bolt 5.
  • first nuts 16 are used to fix the cover 14 on the cylinder head 3 and second nuts 17 are used for the separate, pretensioned mounting of the flange 4 for fastening the injection nozzle 2 in the cylinder head 3.
