Definitions

  • a plurality of injection openings which are used for the direct fuel injection into the combustion chamber of an internal combustion engine
  • the fuel injection valves in this case control the injection of compressed and thus pressurized fuel by the longitudinal movement of a valve needle, which has a valve sealing surface and cooperates with a body seat.
  • a valve needle which has a valve sealing surface and cooperates with a body seat.
  • two basic types are distinguished: on the one hand so-called seat hole nozzles in which the injection openings emanate directly from a conical body seat, and on the other hand so-called blind hole nozzles in which the injection openings start from a blind hole.
  • the blind-hole nozzles have the advantage over the seat-hole nozzles that the distribution of the fuel to the individual injection openings takes place uniformly, as a result of which a more uniform spray pattern is generally achieved than with seat-hole nozzles.
  • the problem arises that the fuel which passes between the valve sealing surface and the body seat, is swirled when passing into the blind hole, so that the effective, applied to the injection openings injection pressure is reduced.
  • a fuel injection valve that works on the principle of the blind hole nozzle.
  • a needle tip is formed on the valve needle, which also in the open position of the valve needle, so if this from the Body seat has lifted, protrudes into the blind hole.
  • the needle tip has a conical sealing surface with which the valve needle is seated on the body seat. This sealing surface is adjoined by a convex, ie outwardly arched region, which in turn merges into a concave region, that is to say inwardly curved region.
  • the end of the valve needle then forms a dome, which is also curved outward and connects tangentially in the concave area.
  • the fuel flow should be deflected into the blind hole without detachment from the needle point in order to avoid turbulence.
  • this has the disadvantage that the shape of the needle tip can not be adapted equally well to all spray holes, since they usually include different angles with the longitudinal axis of the valve needle.
  • only at some of the holes results in an optimized inlet, while other injection openings are rather unfavorably flowed through the applied flow.
  • the fuel injection valve according to the invention with the characterizing features of claim 1 has the advantage over that the inlet of the fuel into the blind hole and thus the effective injection pressure at the injection openings are optimized.
  • the valve needle on a conical valve sealing surface and an adjoining valve needle tip wherein the valve needle tip is concave directly adjacent to the conical valve sealing surface and adjoins the concave needle tip an outwardly curved dome or a flat end face.
  • the fuel flow dissolves when entering the blind hole of the valve needle, but is then redirected from the farther downstream part of the needle tip, so that the fuel leaves the injection openings at high speed and thus with a high effective injection pressure.
  • an edge is formed at the transition of the conical body seat to the blind hole, which, in combination with the configuration of the needle tip, ensures that the inlet of the fuel into the blind hole is further optimized.
  • This embodiment is particularly advantageous when the blind hole has a conical wall from which the injection openings emanate.
  • the needle tip extends so far into the blind hole that the concave needle tip, even when the valve needle is in its open position, reaches up to the height of the injection openings.
  • the concave needle tip is adjoined by a curved dome which forms the end of the valve needle. Depending on how far the valve needle protrudes into the blind hole, turbulence in the blind hole can be reduced.
  • FIG. 1 a fuel injection valve according to the invention is shown in longitudinal section, with only the essential components are shown.
  • the fuel injection valve has a valve body 1, in which a bore 3 is formed with a longitudinal axis 8, wherein the bore 3 is delimited at its combustion chamber end by a body seat 9.
  • the body seat 9 is adjoined by a blind hole 10, from which at least one injection opening 7 originates, wherein a plurality of injection openings 7 are usually provided which are distributed over the circumference of the blind hole 10. It can also be provided that the individual injection openings 7 different inclination angle with respect to the Have bore 3.
  • a piston-shaped valve needle 5 is arranged, which is longitudinally displaceable and which is sealingly guided in a guide portion 15 in the bore 3.
  • valve needle 5 tapers the body seat 9 to form a pressure shoulder 13 and finally goes over into a valve sealing surface 11 at its body-side end.
  • the end of the valve needle 5 finally forms a needle tip 30, which then, when the valve needle 5 rests on the body seat 9, projects into the blind hole 10.
  • a pressure chamber 19 is formed which is radially expanded at the level of the pressure shoulder 13. In the radial extension of the pressure chamber 19 opens an extending in the valve body 1 inlet channel 25 through which the pressure chamber 19 can be filled with fuel under high pressure.
  • valve needle 5 is acted upon at its body seat facing away from the end of a closing force which points in the direction of the body seat 9 and which is generated for example by a spring element or by hydraulic means. Depending on the ratio of this closing force to the hydraulic opening force, which arises essentially by the pressurization of the pressure shoulder 13, the valve needle 5 moves longitudinally within the bore 3. If the valve needle 5 on the body seat 9, the blind hole 10 is opposite the pressure chamber 19 closed. If, however, an injection of fuel take place, the valve needle 5 is moved away either by an increase in pressure in the pressure chamber 19 or by a reduction in the closing force of the body seat 9. As a result, fuel flows between the valve sealing surface 11 and the body seat 9 into the blind hole 10, from where the fuel is ejected via the injection openings 7.
  • FIG. 2 shows an enlarged view of the designated II section of FIG. 1 in the region of the body seat 9.
  • the valve sealing surface 11 is conical, wherein it may also be provided to provide two or more conical surfaces with slightly different angles instead of a conical surface, wherein all opening angles of these conical surfaces, as well as the opening angle of the valve sealing surface 11, are substantially equal to the opening angle of the likewise conical body seat 9.
  • the conical valve sealing surface 11 is followed by a needle tip 30, which is also in the open position of the valve needle 5, the in of the FIG. 2 is shown in the blind hole 10 projects.
  • the needle tip 30 is concave directly following the valve sealing surface 11, ie curved inwards, so that an edge 34 is formed between the valve sealing surface 11 and the needle tip 30.
  • To the needle tip 30 can either, as in FIG. 2 shown, connect a flat face 32, or a dome 36, the in FIG. 2 is indicated by a dashed line. This depends on how far the needle tip 30 protrudes into the blind hole 10, so that a certain calming of the flow in the blind hole 10 can be achieved by the tip 36.
  • the effect described by the needle tip 30 can be further optimized by the fact that between the body seat 9 and the blind hole 10, an inlet edge 38 is formed on the to a certain extent also a detachment of the fuel flow from the wall of the valve body 1.
  • the inlet edge 38 is particularly formed when the wall of the blind hole 10 is conical, as well as in FIG. 2 shown.
  • the separation of the flow does not mean that the other areas in the blind hole 10 and the valve sealing surface 11 form dead water areas in which no flow takes place. Rather, the above description of the flow separation means that the main flow with the highest flow rates the described course, which is determined by this highest flow rate of the injection pressure substantially.
  • the needle tip 30 can also be provided to form the needle tip 30 so long that it extends to the height of the injection openings 7. Depending on the dimensions of the blind hole 10 and the injection pressure used, this can contribute to a better deflection of the fuel into the injection openings 7.
