Definitions

  • the invention is based on a valve for metering a flowing, e.g. gaseous or liquid medium, in particular fuel injection valve for internal combustion engines, according to the preamble of claim 1.
  • a known fuel or fuel injection valve for directly injecting fuel or fuel into the combustion chamber of an internal combustion engine ( DE 103 17 148 A1 ) has a valve housing, a recorded in the valve housing piezoelectric, electrostrictive or magnetostrictive gimbaled actuator, which is operatively connected to a valve needle, an electrical connector and an electrical connection from the connector to the actuator producing supply line.
  • the supply line has two supply lines. Each supply line is composed of an electrical conductor fixed on the housing side, a contact pin protruding from the actuator, which is arranged in the valve housing diametrically to the conductor, and a flexible strand section connecting the conductor to the contact pin.
  • the electrical conductor is a sheathed round wire, which is passed through a valve housing final, an inlet for the fuel end cap, and the bare contact pin is frontally from the actuator.
  • the flexible strand section is in the form of a spring blade which extends transversely to the axis of the valve housing.
  • the spring leaf is soldered or welded with angled blade ends on the one hand to the bare end of the sheathed round wire and on the other hand with the bare contact pin.
  • a fuel injection valve is already known in which the electrical lines of a piezoelectric actuator, for example, are protected against mechanical damage, the contacting of the actuator is improved and made cost-effective.
  • At least one electrical line is provided between two bearings with a strain relief, so that the electrical lines are not mechanically stressed by the high-frequency lifting movements of the actuator or the compensatory movements of a hydraulic coupler.
  • the strain relief is formed such that the length of the electrical line between the two bearings is greater than the axial distance with respect to the valve axis between the bearings. This results in a loop, loop or bend of the electrical line between the bearings.
  • the valve according to the invention with the features of claim 1 has the advantage of a significantly simplified assembly, since the complete wiring of the actuator producing, holistic supply module can be much easier plugged between connector and actuator and only at its conductor ends with connector and actuator must be welded , Compared to the electrical supply line in the known valve described above accounts for a total of four welds, which are additionally required there in the two supply lines in the connection of each spring leaf with round wire and pin.
  • the supply module can be easily and inexpensively produced in the plastic injection process with only two inserted and preformed in the middle line section, electrical conductors.

Due to the plurality of axially offset, meandering curvatures is a small axial spring stiffness of the supply module achieved, so that only occur at very small lifting voltages in the middle conductor sections at an axial temperature of the actuator.
  • the plastic bridge member has a plastic ring bounding the middle conductor sections to the elongated front conductor sections, which is integrally formed on the plastic casing of the front conductor sections, and a plastic disc segment delimiting the elongate rear conductor sections with a central passage opening.
  • the plastic disk segment is integrally formed on the plastic casing of the rear conductor sections and from both middle conductor sections in each case a curvature branch nearest the plastic disk segment of the meandering curvature adjacent to the plastic disk segment is embedded in the plastic disk segment.
  • the plastic disk segment has a disk surface defined by a circular arc and a chord, and is oriented so that the chord of the circle extends parallel to the plane in which the front and rear conductor sections extend.
  • the between the plastic ring on the one hand and the plastic disk segment on the other hand extending plastic sheaths of the two middle conductor portion each have a rectangular cross-section, which is parallel to the chord of the plastic disk segment extending cross-sectional dimension represents the largest cross-sectional dimension and made much larger than the other cross-sectional dimension.
  • the large width of the plastic casing produced thereby increases the torsional rigidity of the plastic bridge member.
  • the electrical conductors consist of a round wire, for example with a diameter of 0.5 mm or from an embossed sheet metal part.
