Definitions

  • the invention relates to a coil, in particular for an electromagnetically actuated fuel injection valve, which has a winding with a precisely defined number of turns on a coil former.
  • the invention further relates to a method for producing such a coil.
  • the invention has for its object to develop a coil, in particular for an electromagnetically actuated fuel injection valve, which has an exactly definable number of turns with the same ohmic resistance. Furthermore, a method for producing such a coil is to be developed.
  • the first-mentioned object is achieved according to the invention in that the coil has a unifilar winding that determines the number of turns and then has a bifilar winding to generate a desired ohmic resistance.
  • both the number of turns and the ohmic resistance can be set very precisely independently of one another in a coil. Different coils therefore have the same current flow at the same voltage and exert a completely identical magnetic force due to the same number of turns. That is why the coils are particularly well suited for electromagnetically actuated fuel injection valves.
  • the second object is achieved according to the invention in that, in order to generate a desired inductance, the winding wire is first unifilarly wound on the coil former and then the ohmic resistance of the coil winding, including an excess wire length, is measured, and then to achieve a desired total resistance, the excess wire length on the basis of the measured resistance value and specific wire resistance is shortened and the excess wire length is then placed in a loop and wound as a bifilar winding on the unifilar winding.
  • This procedure creates a coil with extremely little effort, which has both a precisely definable number of turns and an ohmic resistance that must be precisely maintained.
  • the fuel injector shown has a winding body 2 in a valve housing 1, on which a winding 3 is wound.
  • a soft iron core 4 provided with a through hole 5 extends through the winding body 2 and forms an inlet connection 6 with an end protruding from the valve housing 1.
  • the other end face of the soft iron core 4 is opposed to form an air gap with an armature 7 which has a coaxially extending valve needle 8 on its side opposite the soft iron core 4.
  • armature 7 which has a coaxially extending valve needle 8 on its side opposite the soft iron core 4.
  • a closing member 9 is arranged, which can close a valve outlet 10.
  • a compression spring 11 presses the armature 7 as seen in the drawing and thereby the closing member 9 in the closed position as soon as the winding 3 is not energized. Flows through the winding 3 current, then the armature 7 is attracted to the soft iron core 4, so that the closing member 9 ge in the open position shown reaches.
  • FIG. 2 shows an enlarged view of the coil body 2, on which two contact lugs 12, 13 are attached. From the contact lug 12, the electrical wire is guided to the winding surface of the coil and then wound in a unidirectional direction on the coil until a winding 3a is produced with the desired number of windings. It can be seen that this unifilar winding 3a is followed by a bifilar winding 3b, the end of which is led to the contact lug 13.
  • the bifilar winding 3b is formed by a loop, the length of which is determined after determining the ohmic resistance of the unifilar winding in order to achieve an exact ohmic resistance.
