Definitions

  • the invention relates to a fuel injection device according to the preamble of claim 1.
  • a fastening device for a fuel injection valve for attachment to a suction tube in which the axial fixation of the fuel injection valve on the fuel distributor line or on a plug-in nipple by a fastener, which is designed as a U-shaped securing clip provided with two resiliently resilient legs is.
  • the securing clip engages in the mounted state by corresponding recesses of the plug-in nipple and can be latched into a recess formed as an annular groove in a connecting piece of the fuel injection valve.
  • the axial clearance between the recesses and the securing clip as well as between the annular groove and the securing clip should be kept small in order to achieve an exact fixation of the fuel injection valve without tension of the seal.
  • a disadvantage of the DE 29 26 490 A1 known fastening device is in particular the bracing effect of the various mounting parts on the fuel injection valve.
  • the force flow generated in the fuel injection valve leads to deformations and thus to changes in the stroke of the valve needle to jamming and to a pressure or bending load of the housing parts, which are generally thin-walled and welded together at several points.
  • each fastening measure leads, for example by a support collar to increase the radial extent of the fuel injection valve and thus to an increased space requirement during installation.
  • the fastening device comprises a sleeve which is clamped between a shoulder of the fuel rail and a shoulder of the fuel injection valve and is formed of an elastic material. Due to its tubular structure, the sleeve can transfer the hold-down forces to the fuel injector only to a limited extent effectively.
  • the claimed by the shoulders of the fuel injector and fuel rail surfaces of serving as hold down sleeve represent the manufacturing edges resulting in the production of the blank of the sleeve cutting edges.
  • the fuel injection device with the characterizing features of claim 1 has the advantage that a direct and thus very accurate Vermosfix ist between fuel injector and connecting piece is created by simple measures on the fuel injector and the connection piece.
  • a pin-shaped raised pin is provided on the fuel injection valve, which corresponds to a groove-like recess or recess on the connection piece of the fuel distribution line. The protruding into the recess pin of the fuel injector ensures regardless of the hold-down for a rotation of the fuel injection valve against the fuel rail and for a reliable assignment of the rotational position of the blank holder to the fuel injection valve.
  • the hold-down in the circumferential direction with an open area in such a way that it is penetrated by the connection plug of the fuel injection valve, so that a clear installation position is defined for the hold-down.
  • a Verwarfix ist the blank holder against the connection piece is eliminated by the pairing Spigot / recess on the fuel injector / connecting piece.
  • the holding-down device is mounted on the fuel injection valve in such a way that a hold-down clip subjected to bending stress is directed away from the connection plug of the fuel injection valve.
  • FIG. 1 a partially illustrated fuel injection device with a first hold-down in a side view
  • FIG. 2 the fuel injection device according to FIG. 1 in a perspective view
  • FIG. 3 A second embodiment of a fuel injection device in a perspective view
  • FIG. 4 in the fuel injectors of FIGS. 1 to 3 used hold-down as a single component
  • FIG. 5 a second embodiment of a hold-down
  • FIG. 6 a third embodiment of a hold-down.
  • FIG. 1 is shown as an embodiment, a valve in the form of an injection valve 1 for fuel injection systems of mixture-compression spark-ignited internal combustion engines in a side view.
  • the fuel injection valve 1 is part of a fuel injection device.
  • the fuel injection valve 1 which is designed in the form of a direct-injection injector for injecting fuel directly into a combustion chamber of the internal combustion engine, is installed in a receiving bore of a cylinder head, not shown.
  • a sealing ring 2, in particular of Teflon®, ensures optimum sealing of the fuel injection valve 1 with respect to the wall of the cylinder head.
  • the valve receptacle can also be provided on a receiving socket of a suction pipe, not shown.
  • the fuel injection valve 1 has at its inlet-side end 3 a plug connection to a fuel distributor line 4, which is represented by a sealing ring 5 between a connecting piece 6 of the fuel distributor line 4, which is shown in section, and an inlet connection 7 of Fuel injection valve 1 is sealed.
  • the fuel injection valve 1 has an electrical connection plug 8 for the electrical contacting for actuating the fuel injection valve 1.
  • a hold-down device 10 is provided according to the invention between the fuel injection valve 1 and the connecting piece 6.
  • the hold-down device 10 is designed as a bow-shaped component, for example as a stamped and bent part.
  • the hold-down 10 has a part-ring-shaped base element 11, wherein this base element 11, which does not rotate through 360 °, but for example has only an extension of about 250 ° to 320 °, is supported on a shoulder 12 of the fuel injection valve 1.
  • axially resilient hold-down bracket 13 of the hold-down 10 abuts a downstream end surface 14 of the connecting piece 6 to the fuel rail 4 in the installed state.
  • the hold-down 10 is interrupted, wherein the hold-down 10 forms a closed bracket element, in particular the FIGS. 2 to 4 clarify. In this way, the hold-down 10 can surround the fuel injector 1 and still allows the passage of the electrical connector plug 8.
  • the hold-down bar 13 protrudes with its resilient brackets from the connector 8 away.
  • a pin-shaped raised pin 15 is provided on the fuel injector 1, which corresponds to a groove-like depression or recess 16 on the connecting piece 6 of the fuel manifold 4.
  • the protruding into the recess 16 pin 15 of the fuel injector 1 provides a direct and thus very secure rotation of the fuel injector 1 relative to the fuel rail 4 and for a reliable assignment of the rotational position of the blank holder 10 to the fuel injector 1.
  • the recess 16 on the connecting piece 6 of the fuel distributor line 4 extends from the end face 14 and extends in slot-like or groove-like manner in the axial direction.
  • the recess 16, which is introduced, for example, by machining, has such an axial extent that the pin 15 of the fuel injection valve 1 can be received in full length.
  • FIG. 2 is the fuel injection device according to FIG. 1 shown in a perspective view. This illustration particularly clarifies the mounting position of the hold-down 10 between the shoulder 12 and the end face 14 and the engagement of the pin 15 in the recess 16.
  • FIG. 3 in a perspective view shown second embodiment of a fuel injection device differs from the in FIG. 2 illustrated embodiment, in particular in the embodiment of the connecting piece 6 and the recess 16.
  • the connecting piece 6 of the fuel distribution line 4 has at its downstream end on a collar annular protruding collar 19, on which the end surface 14 is formed to bear the hold 10 with its hold-down bracket 13 and in which the recess 16 is formed.
  • the groove-like recess 16 is completely penetrated by the pin 15 in the installed state of the fuel injection valve 1.
  • the recess 16 is introduced by means of punching or by machining.
  • FIGS. 4 to 6 three embodiments of downers 10 are shown, wherein the in FIG. 4 shown as a single component hold-down 10 in the fuel injectors of FIGS. 1 to 3 used holdings corresponds to 10. All embodiments are characterized in that, starting from a planar part-ring-shaped base element 11, at least one bent, axially resilient hold-down bracket 13 extends out of the plane of the base element 11.
  • the base member 11 is formed like a spider and surrounds the fuel injection valve 1 in the region of its inflow-side end 3. As already described, penetrates the connector 8 of the fuel injection valve 1, the open area 20 of the base member 11 of the blank holder 10.
  • the base member 11 may be substantially circular ( FIGS. 4 and 5 ) or depending on the shape of the fuel injection valve 1, for example pear-shaped ( FIG. 6 ) or similar in cross section.
  • the base member 11 is made flat, for example, with a thickness of about 1.5 mm, so that a large bearing surface on the shoulder 12 is present.
  • the basic elements 11 of the hold-down 10 of the FIGS. 5 and 6 upright, for example, in turn, with a wall thickness of about 1.5 mm, but thus also dictates the small width of the support surface of the respective base member 11 on the shoulder 12.
  • the hold-down 10 represents a closed bracket member, since the hold-down bar 13 is connected endlessly to the base member 11. From the base member 11, two webs 21 extend with increased width largely in the axial direction and thus substantially perpendicular to the extension plane of the base member 11. These webs 21 go kinked into the actual axially resilient holddown 13, wherein the hold-down bracket 13 composed of three essential sections.
  • the hold-down bar 13 has, starting from the webs 21, only a small axial extent, which results from two uniform oblique sections 22.
  • the oblique sections 22 merge into slightly curved contact sections 23 which, in the installed state, ultimately have touching contact with the end face 14 of the connecting piece 6.
  • a connecting portion 24 is provided, which is carried out slightly lowered relative to the abutment portions 23 and ensures that the entire hold-down device 10 is closed.
  • the circumferential extent of the hold-down strap 13 with its sections 22, 23 and 24 largely corresponds to that of the base element 11, but in a different axial plane, caused by the height of the webs 21st
  • the oblique sections 22 merge into slightly curved contact sections 23 which, in the installed state, ultimately have touching contact with the end face 14 of the connecting piece 6.
  • the two abutment sections 23 of each hold-down 10 terminate the two-part hold-down bar 13 in this way.
