  • the fuel manifold extends above the engine head and is connected to the injector through a bush projecting from the fuel manifold.
  • the injector is coupled to the seating by means of a ball coupling.
  • the fuel manifold is rigidly secured to the engine head of the engine.
  • An opposing spring is interposed between the fuel manifold and the injector to compress the injector inside the seat.
  • WO 03/054383 A1 discloses a fixing device for reciprocally fixing a fuel injection valve to a cylinder head in an internal combustion engine and for fixing the fuel injection valve to a fuel distribution line.
  • the fixing device is embodied in the form of a spring clip comprising undulated spring shackles which press against a shoulder of the fuel distribution line.
  • WO 00/42315 A1 discloses a spring clip which includes a first portion including a bridge connecting spaced elongate fingers adapted to straddle a body portion of a fuel injector and be receivable in a receiving portion of a fuel rail cup.
  • the elongate fingers include a reverse bend at a midpoint therealong and terminate in a bridging portion.
  • the bent elongate defines finger segments on each side of the revere bend. The finger segments diverge from the reverse bend part way toward the bridge and bridging portions and converge thereaf-ter to form generally diamond shaped spring elements.
  • a second portion of a generally planar shape having spaced legs engages slots in the injector body.
  • the second portion includes a wall portion extending generally perpendicular to the spaced legs and connects with the bridging portion.
  • WO 03/038267 A1 discloses a fixing device for reciprocally fixing a fuel injection valve to a cylinder head of an internal combustion engine and for fixing the fuel injection valve to a fuel distribution line.
  • the fixing device comprises two spring tongue elements which can be inserted into a retaining groove of the fuel injection valve or the fuel distributor line.
  • a center distance of the spring tongue elements is less than the largest diameter of the opening surface surrounded thereby and the spring tongue elements are resilient in a radial direction in relation to an axis of the fuel injection valve.
  • At least two spring elements are formed in an axial direction in relation to the spring tongue elements and are resilient with respect to traction and pressure.
  • the spring elements can be detachably linked to the opposite lying fuel injector valve or fuel distributor line in an axial non-positive fit by means of a locking connection.
  • the object of the invention is to create a fuel cup, a holder for fixing an injector to the fuel cup and an injector assembly which enable a proper coupling of the injector to the fuel cup.
  • the invention is distinguished concerning a first aspect of the invention by a holder for fixing an injector to a fuel cup.
  • the holder comprises a bottom portion, a first side portion, a notch of the holder, an injector recess, and at least one elastic element.
  • the first side portion extends away from a first side of the bottom portion and comprises the notch of the holder.
  • the notch of the holder is arranged for engaging the notch of the holder to a notch of the fuel cup.

  • the notch of the holder enables a simple coupling of the holder to the fuel cup. This contributes to a simple assembling of the injector to an internal combustion engine.
  • the injector recess enables the positive connection between the holder and the injector. This contributes to a simple assembling of the holder to the injector. If the injector with the holder and the fuel cup is arranged in the internal combustion engine, the elastic elements are preloaded. So, the elastic elements apply a given force to the injector towards a combustion chamber of the internal combustion engine. This contributes to that the injector is pressed into a seat of the injector at the internal combustion engine despite a pressure which may be applied on the injector towards the fuel cup because of a pressure in the combustion chamber.
  • the fuel cup recess with its diminution contributes to a simple design of the notch of the holder and so to a low-cost production of the notch of the holder.
  • the notch of the fuel cup comprises a T-shaped fixing element which may be introduced into the fuel cup recess for engaging the holder to the fuel cup.
  • the fuel cup is coupled to a fuel rail and/or a part of the fuel rail.
  • the holder comprises a second and a third side portion.
  • the second and the third side portions are coupled to a second and, respectively, a third side of the bottom portion of the holder.
  • the second and the third side portions are arranged opposite to each other and each comprise at least one elastic element. This may contribute to apply an even load on the injector through the elastic element. This contributes to a proper coupling of the injector to the injector seat of the internal combustion engine.
  • the elastic elements each comprise at least one bended arm.
  • Each bended arm is coupled to the bottom portion at a first end of the bended arm.
  • the bended arm extends away from the bottom portion and then bends back towards the bottom portion.
  • Each bended arm has a second end of the bended arm.
  • the second end of the bended arm has a given distance to the bottom portion.
  • each bended arm comprises an extension at a bended part of the bended arm for a coupling of the extensions to shoulders of the fuel cup. This contributes to a proper coupling of the bended arms to the fuel cup. This contributes to apply the given force on the injector properly.
  • the injector recess of the holder is open towards a fourth side of the bottom portion facing away from the first side of the bottom portion of the holder.
  • the injector recess comprises an orientation element of the holder for avoiding a rotation of the holder relative to the injector around an axis of the injector. This enables the positive connection of the holder to the injector in a simple way. So, this contributes to a proper fixation of the holder to the injector.
  • the holder comprises back stops for each of the bended arms.
  • the back stops extend away from the bottom portion towards the second ends of the bended arms.
  • the back stops of the bottom portion have the given distance to the second ends of the bended arms. This may contribute to stabilize the bended arms of the holder. This contributes to a proper functionality of the holder over a long lifetime of the holder.

  • the T-shaped fixing element is especially advantageous in combination with the fuel cup recess of the holder.
  • the T-shaped fixing element comprises a first section and a second section.
  • the second section is broader than the fuel cup recess of the holder.
  • the first section is arranged between the fuel cup and the second section is slightly broader than the diminution of the fuel cup recess and smaller than the fuel cup recess. This enables to introduce the T-shaped fixing element into the fuel cup recess by slightly bending the first side portion of the holder in such a way that the diminution gets at least as broad as the first section of the T-shaped fixing element. This enables to form the notches in a very simple way.
  • the fuel cup comprises at least two shoulders.
  • the two shoulders are formed and arranged at the outside of the fuel cup opposite to each other for a coupling with the elastic elements of the holder. This contributes to a proper coupling of the bended arms to the fuel cup. This contributes to apply the given force on the injector properly.

  • the extensions of the bended arms of the holder are coupled to the shoulders of the fuel cup.
  • An injector assembly ( figure 1 ) comprises an injector 2, a holder 4, and a fuel cup 6.
  • the injector assembly is arranged at an internal combustion engine for injecting fluid into a combustion chamber of the internal combustion engine.
  • the fuel cup 6 is coupled to a fuel rail and/or a part of the fuel rail.
  • the injector 2 comprises an injector tip 3 facing away from the fuel cup 6.
  • the injector tip 3 comprises at least one injector opening through which the fuel may be injected into the combustion chamber.
  • the injector 2 is arranged at the internal combustion engine in such a way that a step 5 of the injector is coupled to an injector seat of an engine head of the internal combustion engine.
  • the holder 4 comprises a notch of the holder 4.
  • the notch of the holder 4 is arranged for engaging the notch of the holder 4 to an notch of the fuel cup 6.

  • the holder 4 further comprises at least one elastic element.
  • the elastic element is arranged in such a way that, if the injector assembly is arranged at the internal combustion engine, the injector 2 is pressed in its injector seat by the elastic element.
  • the holder 4 comprises two elastic elements which are arranged at two opposite sides of the holder 4. This contributes to an even load on the injector 2.
  • the elastic elements each comprise a bended arm.
  • the holder 4 comprises a bended arm 14 of a second side portion of the holder 4 and a bended arm 16 of a third side portion of the holder 4.

  • the holder 4 further comprises an extension 18 of the bended arm 14 of the second side portion and an extension 20 of the bended arm 16 of the third side portion.
  • the extensions are formed for improving the coupling of the elastic elements to the fuel cup.
  • the extensions are formed for improving the coupling of the extensions to a first and, respectively, a second shoulder 22, 24 of the fuel cup 6.
  • the extensions and the shoulders enlarge a coupling surface between the holder 4 and the fuel cup 6. This contributes to a proper load transfer from the fuel cup 6 to the injector 2, if the injector assembly is arranged at the internal combustion engine. For example, if the coupling surface between the elastic elements and the fuel cup 6 would be too small, the contact of the elastic elements to the fuel cup 6 may be lost during operation of the internal combustion engine because of vibrations of the internal combustion engine.
  • the notch of the fuel cup 6 comprises a T-shaped fixing element 26.
  • the T-shaped fixing element comprises a first section 28 of the T-shaped fixing element 26 and a second section 30 of the T-shaped fixing element 26.
  • the T-shaped fixing element 26 is formed in such a way that the first section 28 is slightly broader than the diminution 12 of the fuel cup recess 10 and that the second section 30 is broader than the fuel cup recess 10 of the holder 4. This enables the engaging of the T-shaped fixing element 26 into the fuel cup recess 10 of the holder 4.
  • the injector 2 comprises a fuel connection 34.
  • the fuel connection 34 is arranged for sealingly coupling the injector 2 to the fuel cup 6.
  • the fuel connection 34 may be introduced into an injector recess of the fuel cup 6.
  • the injector 2 may comprise a sealing 36.
  • the injector 2 comprises a groove 38 of the injector 2.
  • the groove 38 of the injector 2 is arranged at the fluid connection 34.
  • the groove 38 may at least partly extends around the circumference of the fluid connection 34.
  • the groove 38 comprises two C-shaped parts ( figure 4 ) and at least one orientation element 40 of the injector 2.
  • the orientation elements 40 may comprise a rectangular shape.
  • the orientation elements 40 of the injector 2 are arranged for a coupling with an orientation element 35 of an injector recess 33 of the bottom portion 31 of the holder 4.
  • the orientation elements 40 of the injector 2 are coupled to the orientation element 35 of the injector recess 33 and if the holder 4 is clamped to the injector 2, the orientation elements avoid a rotation of the holder 4 around an axis of the injector 2.
  • the injector recess 33 of the holder 4 and the groove 38 of the injector 2 are formed and arranged in such a way that the holder 4 may be clamped to the injector 2 in such a way that a border of the injector recess 33 may be arranged partly in the groove 38.
  • the injector recess 33 of the holder 4 comprises an open end facing away from the first side portion 8 of the holder 4.
  • the holder 4 While assembling the injector assembly, for example, at an assembly line, the holder 4 may be clamped to the injector 2. Afterwards, the fluid connection 34 of the injector 2 is introduced into the fuel cup 6 and the T-shaped fixing element 26 is introduced into the fuel cup recess 10 of the holder 4. If the T-shaped fixing element 26 is engaged in the fuel cup recess 10, the fuel cup 6, the holder 4, and the injector 2 may be handled as one part. This is especially advantageous for the assembling of the injector assembly to the internal combustion engine.
  • the whole fuel rail of the internal combustion engine may be assembled in such a way that all injectors 2 of the fuel rail are clamped at their fuel cups 6 of the fuel rail and that the whole fuel rail with the injectors 2 may be handled as one piece.
  • the injector 2 is arranged in its injector seat of the engine head of the internal combustion engine, for example, a screw may be stuck through a fixing recess 32 of the fuel cup 6. If the fuel cup 6 is fixed by the screw at the engine head, the notches loose their sense and do not further contribute to fix the injector 2 to the fuel cup 6. However, then the fuel cup 6 loads the elastic elements of the holder 4. The load on the elastic elements leads to a bending of the bended arms towards the bottom portion 31. The back stops may contribute to that the bended arms are not bended in such a way that the bended arms break.
  • the back stops may also are bended and contribute to increase the elastic force of the elastic elements.
  • the load is transferred to the injector 2 in such a way that the injector 2 is pressed against its injector seat in the engine head. This contributes to that the injector 2 stays in its injector seat despite a pressure which may force the injector 2 away from its injector seat and which may be produced by a pressure in the combustion chamber of the internal combustion engine.
  • the holder 4 may comprise only one or more than two elastic elements.
  • the elastic elements may be formed alternatively, for example by springs.
  • the notches may comprise an alternative embodiment and/or there may be arranged further notches.
  • the bended arms may be formed without the extensions and the fuel cup 6 may be formed without the shoulders, respectively.
