Definitions

  • Fluid injection device for internal combustion engines The invention relates to a fluid injection device for internal combustion engines, as it is known, for example, the force ⁇ direct fuel injection in compression-ignition internal combustion engines. From DE 100 24 703 AI a fuel injection valve is known, in which the valve needle is guided in a middle section with very little play in the pressure chamber. To one
  • valve needle To allow passage of fuel, lateral cuts are provided on the valve needle.
  • the components, in particular the valve needle and the pressure chamber must be worked very precisely, which leads to increased costs in the production, since the machining of the inside of a bore is always associated with great effort.
  • a precise guidance of the valve needle is sought in order to achieve a high accuracy in the metering of the fuel and a symmetrical atomization of the fuel.
  • a precise guidance of the valve needle reduces the wear on the valve seat.
  • a fluid injection device for internal combustion engines is specified, in particular a fluid injector.
  • the fluid injection device is, for example, example, a fuel injection device, in particular a fuel injector.
  • the fluid injector includes a valve body in which a valve needle is slidably disposed along a longitudinal axis of the valve body and cooperates with a valve seat to expose or close a fluid outlet.
  • the fluid outlet is a fuel outlet.
  • Fluid injection device has at least one spring element as a guide of the valve needle, which is arranged between the valve body and the valve needle and by means of which the valve needle is supported on the valve body.
  • the spring element is arranged in the radial direction between the valve needle and a circumferential side wall of the valve ⁇ body.
  • the spring element in particular bridges the radial gap between the valve needle and the side wall.
  • the circumferential side wall delimits the cavity of the valve body, through which fluid flows from an inlet of the fluid injector to the fluid outlet and in which the valve needle is arranged, in particular in the radial direction.
  • the spring element can be compressed in particular in the radial direction. Under that the spring element is a guide of
  • Valve needle is, in particular, understood that the spring element prevents tilting of the valve needle relative to the longitudinal axis during operation of the fluid injection device or at least largely prevented.
  • the valve needle is centered by means of the spring element with respect to the longitudinal axis and guided axially.
  • the valve needle is therefore not directly guided by rigid body and in particular not directly by housing parts, but for guiding serves at least one spring element, which in turn is connected to the valve body.
  • This has the advantage that a particularly high accuracy in the manufacture of the components is not required.
  • the needle does not have to be guided without play. Rather conveys to ⁇ least one spring element managers - in particular radially directed executives - between the valve needle and the valve body. If the spring element is designed such that these guiding forces are symmetrical, precise guidance of the valve needle is possible.

  • a support of the valve needle on the valve body by the spring element is understood here and below that a force transmission from the valve needle to the valve body and vice versa by the spring element is possible.
  • the spring element exerts restoring forces on the valve needle, which effect a centered guidance of the valve needle.
  • the return actuating forces act expediently in particular in the radial direction on the valve needle.
  • the spring element in particular the radial restoring forces opposing forces on the valve body, in particular on its side wall. Emotional If the valve needle for opening or closing the fluid outlet, the spring element in one embodiment additionally exert axial restoring forces on the valve needle.
  • the at least one spring element to a bias, in the fully assembled state of the fluid injection device and regardless of the position of the valve, that is, from the position of the valve needle.
  • the spring element is biased in the radial direction. For example, it is compressed in the radial direction in the radial gap between the valve needle and the side wall of the valve body clamped.
  • the spring element on the outer contours of a torus which is formed by a coil spring.
  • the coil spring has a torus as an envelope.
  • the turns of the helical spring may conveniently be wound around a curved and closed centerline, especially about a circular centerline, which is particularly the centerline of the torus.
  • the center line is expediently only an imaginary line.
  • Such a spring element is suitable to effect a symmetrical restoring force on the valve needle and thus a secure guidance.
  • Such a spring element is also suitable for effecting a symmetrical restoring force and thus reliable guidance of the valve needle. It is very easy to install.
  • At least two spring elements are provided, which are designed as helical springs and spaced along the circumference of the valve needle between the valve needle and the valve body are arranged, in particular opposite each other.
  • Fuel can easily pass through both a coil spring and a spider spring. A particularly large hydraulic diameter can be achieved, so that no further means for a fuel passage through the interior of the fluid injection device are necessary.
  • at least one first spring element on a fluid outlet facing portion of the valve needle and at least one second spring element in a remote from the fluid outlet portion of the valve needle are arranged.
  • the first and second spring members are adjacent opposite axial ends of the valve needle.
  • the at least one spring element is formed of a corrosion-resistant spring steel, wherein the corrosion resistance refers to the fuel used, with which the spring element is in contact.

  • Fluid injector 1 slidably and in the present case firmly connected to the valve needle 5. So he takes the valve needle 5 with it when it moves axially. The valve needle 5, when displaced in a direction away from the valve seat 9, releases the nozzle 11, thereby allowing the escape of fluid - i. present e.g. Fuel or urea solution - through the nozzle 11.
