  • the Swirl element has an inner opening area several swirl channels that are not with the outer circumference of the swirl element. The whole Opening area extends completely over the axial Thickness of the swirl element.
  • a disadvantage of the above-mentioned document known fuel injection valve is in particular the high production costs, on the one hand in increased Production costs and on the other hand in inhomogeneities in the injected mixture cloud and resulting asymmetrical beam patterns as well as deviant Flows down.
  • the fuel injection valve according to the invention with the characterizing features of claim 1 has In contrast, the advantage that the swirl module by the small dimensions of the cord-twisted together Wires, which include spin-generating cavities, very can be made small.
  • the swirl module can in easy way in any, standard Fuel injection valves are used.
  • By the Arrangement of the swirl module on the downstream side of the Sealing seat can be any injection angle relative to Longitudinal axis of the fuel injection valve can be realized without having to divert the fuel jet.
  • wires for example, tungsten to produce or in the form of glass fibers, since This reduces the diameter of the wires to a minimum can be.
  • the sleeve, the receiving member and the wires are subject not the demand for high precision, so that all Components are inexpensive to produce.
  • a fuel injection valve 1 is in the form of a Fuel injection valve 1 for fuel injection systems of mixture-compacting, externally ignited Internal combustion engine running. This is suitable Fuel injection valve 1 in particular for direct Injecting fuel into a not shown Combustion chamber of an internal combustion engine.
  • the fuel injection valve 1 consists of a Nozzle body 2, in which a valve needle 3 is arranged.
  • the valve needle 3 is connected to a valve closing body 4 in Operative connection, with a on a valve seat body. 5 arranged valve seat surface 6 to a sealing seat interacts.

  • the magnetic coil 10 is in a coil housing 11 encapsulated and wound on a bobbin 12, which rests against an inner pole 13 of the magnetic coil 10.
  • the magnetic coil 10 is connected via a Line 19 of a via an electrical plug contact 17th energized electric current.
  • the plug contact 17 is surrounded by a plastic sheath 18, the Inner pole 13 may be molded.
  • the valve needle 3 is in a valve needle guide fourteenth guided, which is designed disk-shaped. to Stroke adjustment is a paired shim 15.
  • An the other side of the dial 15 is a Anchor 20. This is about a first flange 21st non-positively connected to the valve needle 3 in conjunction, which by a weld 22 with the first flange 21 connected is.
  • On the first flange 21 is supported Return spring 23 from which in the present design of Fuel injection valve 1 by a sleeve 24 Bias is brought.
  • the fuel injection valve 1 is through a Seal 28 against a not shown Fuel line sealed.
  • a swirl module 34th Downstream of the sealing seat is a swirl module 34th arranged, which preferably under a spray-off angle ⁇ with respect to a longitudinal axis 35 of the Fuel injection valve 1 is inclined.
  • the swirl module 34 is shown in more detail in Figures 2 and 4 and 5.
  • the armature 20 drops sufficient reduction of the magnetic field by the pressure of the Return spring 23 from the inner pole 13, causing the with the valve needle 3 operatively connected flange 21st moved against the stroke direction.
  • the valve needle 3 is thereby moved in the same direction, causing the Valve closing body 4 touches on the valve seat surface 6 and the fuel injection valve 1 is closed.
  • Fig. 2 shows in a partial sectional view of a enlarged view of the discharge-side part of the in Fig. 1st described first embodiment of a Fuel injection valve according to the invention 1.
  • the shown detail is designated in Fig. 1 with II.
  • Matching components are matched Provided with reference numerals.
  • the valve seat body 5 acts on the valve seat surface 6 with the valve closing body 4, which is connected to the valve needle. 3 is trained. Downstream of the sealing seat is the Swirl module 34 is arranged, which is aligned so that a longitudinal axis 36 of the swirl module 34 with the longitudinal axis 35 of the fuel injection valve 1 includes the angle ⁇ . Thus falls the longitudinal axis 36 of the swirl module 34 with the Beam axis of the fuel jet together, creating a Beam deflection and resulting inhomogeneities and Asymmetries are avoided.
  • the swirl module 34 consists of a receiving component 37, which the injection opening 7, a swirl chamber 38 and the actual swirl unit 39 contains.
  • the receiving member 37 can be cylindrically shaped and in a corresponding recess 40 of the valve seat carrier. 5 be used.
  • the swirl chamber 38 is downstream of the Swirl unit 39 is arranged and tapers in Flow direction to the injection opening 7.
  • Fig. 3 shows a schematic representation of a Section along the line III-III through the Fuel injection valve 1 in Fig. 2 with something changed Diameter of the valve seat body 5 in the cutting area.
  • valve closing body 4 in the region of Valve seat body 5 with at least one bevel 40th Mistake are off Symmetrieschreibn four polished sections 40 on the valve closing body. 4 designed to be a volume 41 between the Valve-closing body 4 and the valve seat carrier 5 on the one hand to keep small to avoid turbulence, on the other hand, to avoid throttling effects sufficiently large. In this way, the Movement of the valve needle 3 and the leadership of the Valve-closing body 4 in the valve seat body 5 by a Radial equilibrium of forces run undisturbed.
  • Fig. 4 shows in an excerpted sectional view of a schematic view of the swirl unit 39 in the area IV in Fig. 2.
  • the swirl unit 39 consists of several, in the illustrated preferred embodiment three, fine wires 42, the For example, consist of tungsten or as glass fibers can be executed.
  • the wires 42 are in one Recess 43 of a sleeve 44 arranged and fill it almost completely off. Between the wires 42 are Cavities 45 formed, which for the fuel guide are responsible. Each of the cavities 45 acts like a Flow channel. To create a twist, the Cavities 45 extend helically in the sleeve 44. The corresponding shape is achieved in that the wires 42nd in the recess 43 of the sleeve 44 kordelä Colour be twisted against each other.
  • Wires 42 By twisting the Wires 42 takes the axial length of the wires 42 existing cord, the cross section of the entirety of Wires 42 or the cord, however, so that the wires 42 to an inner wall 46 of the recess 43 of the sleeve 44th abut and caulk thereby. This will be the Wires 42 fixed in the sleeve 44. Alternatively, the Wires 42 also by squeezing the sleeve 44th be caulked.
  • the entire swirl module 34 can be kept small. This can the dead volume of the downstream of the swirl unit 39th arranged swirl chamber 38 also be very small whereby the swirl flow also between two injection cycles of the fuel injection valve 1 in the swirl chamber 38 is obtained and can remain homogeneous.
  • Fig. 5 shows a schematic representation of a Section through the swirl unit 39 shown in FIG along the line V-V in FIG. 4.
  • the swirl unit 39 three wires 42 which in the recess 43 of the sleeve 44th are arranged.
  • the wires 42 are located on the inner wall 46th the sleeve 44 on.
  • the not filled by the wires 42 Residual volume forms the cavities 45, which serve as flow channels act.
  • swirl module 34 Due to the small dimensions of the swirl module 34 can standard fuel injection valves 1 easily so be equipped. A receiving bore 47 in Valve seat body 5, in which the swirl module 34 is inserted is easy and inexpensive to install. The individual components of the swirl module 34 are also simple assemble, reducing the manufacturing cost in comparison for conventional spin conditioning or solutions, which are arranged on the inflow side of the sealing seat, decreases significantly.
  • Embodiment limited and z. B. also for Fuel injection valves 1 with a larger number of Wires 42 and for any types of Fuel injectors 1 applicable.
