Definitions

  • the invention relates to a pressure accumulator which is suitable for a common rail system in a large diesel engine.
  • Large diesel engines are used, for example, as main propulsion units for ships or as stationary systems for power generation. They are usually designed as slow-running two-stroke crosshead machines or as four-stroke machines.
  • fuel injection, gas exchange, water injection and possibly auxiliary systems, e.g. B. for control oil operated with common rail systems.
  • the respective fluid eg. B. the fuel for injection, a hydraulic medium for actuating the exhaust valves or a working medium for controlling the injection, promoted under high pressure in a pressure accumulator, which is also referred to as an accumulator.
  • the pressurized fluid from the respective accumulator is then used to supply all of the cylinders of the internal combustion engine or to control the valves and the fuel injection devices.
  • the pressure accumulators are each designed as tube-like components which are closed at both ends and which extend approximately at the level of the cylinder heads along the engine.
  • the tubular base bodies of the pressure accumulators typically have a plurality of holes which the storage space of the pressure accumulator can be connected to the respective supply or actuation devices of the individual cylinders.
  • the pressure in the associated pressure accumulator can be up to 2000 bar, for example. In operation, it is especially the dynamic, e.g. B. caused by pressure fluctuations, loads that place high mechanical demands on the pressure accumulator.
  • the high-pressure strength of the pressure accumulator is also limited in particular by the radial bores. These can increase the voltages, for example the reference voltage, by a factor of three to four and more.
  • DE-A-199 49 962 proposes that the interior of the base body serving as the storage space be formed flat in the region of the mouth of the bores, in order in this way to stress peaks in the intersection area between the bores and the Reduce body. These flat areas are subsequently produced by local, material-removing processing.
  • the object of the present invention is to propose a pressure accumulator for a commmon rail system of an internal combustion engine, in which the very simple measures allow a very high internal pressure with dynamic loading without the external dimensions and thus the space requirement of the pressure accumulator being increased.
  • the pressure accumulator should be suitable for a common rail system of a large diesel engine and especially for a fuel injection system.
  • a pressure accumulator for a commmon rail system of an internal combustion engine is proposed with a tubular base body with a wall, one in the interior of the base body provided storage space for the medium to be stored limited, and with at least one hole for removing the medium, which extends through the wall.
  • On the inside of the wall there is at least one curved curvature which extends into the storage space and is arranged such that the bore opens into the storage space within the curved curvature.
  • this inward-reaching curvature can significantly reduce the stress increases caused by the bore.
  • the optimized internal shape of the pressure accumulator given the fatigue strength of the material from which the base body is made, the permissible internal pressure for dynamic loads can be increased significantly, or the external dimension of the pressure accumulator, in particular its diameter, can be reduced because, for example, the wall can be made thinner.
  • What is essential here is the knowledge of the area in which the bore opens into the storage space. with a finite curvature - in particular not exactly - to design.
  • said area has a curvature that has the opposite sign as the curvature of the remaining part of the inside of the wall, which delimits the essentially cylindrical storage space.
  • the curvature preferably extends over a substantial part of the length of the storage space and particularly preferably over the entire length of the storage space.
  • the inner profile of the storage space that is to say its section perpendicular to the longitudinal axis, is the same over the entire length of the storage space. This means that local internal processing of the storage space can be dispensed with, which makes production significantly easier.
  • the base body with the storage space can be produced in a simple manner, for example by extrusion, casting or broaching with a correspondingly shaped broaching tool.
  • a further advantageous measure is to provide on the inside of the wall at least two - for example three - curved arches which extend into the storage space and each extend over a substantial part of the length of the storage space and at different positions with respect to the circumferential direction of the inside of the wall are provided. There are therefore a number of bulges provided on the inner circumference, each of which preferably extends over the entire length of the storage space.
  • bores pointing in different directions can be provided, which significantly increases the flexibility of the pressure accumulator with regard to its connection options.
  • each bore opens into the storage space in the middle of the curvature with respect to the circumferential direction of the inside of the wall, that is to say the central axes of the boreholes lie in the center of the curvature.
  • the bores eccentrically or offset from one another. It is essential that the bores open into the storage space within the arch.
  • each curvature preferably has a height in the radial direction that is between 5% and 30% of the inside diameter of the storage space. This height means the maximum amount that the arch protrudes into the storage space via the otherwise, for example, circular contour of the cross section of the storage space.
  • the curvature according to the invention which extends into the storage space, can be realized particularly preferably by the storage space comprising at least two essentially cylindrical longitudinal bores which are arranged in such a way that their cross sections overlap.
  • a particularly preferred variant consists in realizing the storage space by means of two cylindrical longitudinal bores, the axes of which run parallel and are spaced from one another in such a way that the cross sections of the longitudinal bores overlap. This means that the distance between the axes of the Longitudinal bores is smaller than the sum of the radii of the two longitudinal bores.
  • This measure results in a storage space whose inner profile (cross-sectional area perpendicular to the longitudinal axis) has the shape of an eight. The area where this figure eight is "constricted” then forms two curved arches extending into the storage space in the sense of the present invention.
  • the storage space has at least two overlapping longitudinal bores offers the advantage of particularly simple manufacture. It is only necessary to make two (or more) longitudinal bores in the tubular structure from which the base body is made.
  • the wall of the base body has at least one flattened portion on its outside, which is arranged and designed such that the bore on the outside of the wall opens into a flat surface.
  • This measure makes it possible to provide actuating or supply devices directly on the outside of the wall, which are to be acted upon by the medium from the pressure accumulator - for example slide valves for fuel injection. This has the advantage that there is no need for high-pressure-resistant connecting lines.
  • a further advantageous variant consists in that the wall of the base body has at least one flat strip on its outside, which extends essentially over the entire length of the tubular base body. This makes it possible, for example, to provide a heating element on the outside of the high-pressure accumulator in order to apply heat to the medium in the storage space.
  • the flat strip can also serve as a support, for example for fastening the pressure accumulator.
  • the pressure accumulator according to the invention is particularly suitable for the common rail system of a large diesel engine and especially for the common rail system for fuel injection.
  • FIG. 1 shows a cross section through a first embodiment of a pressure accumulator according to the invention, which is generally designated by the reference numeral 1. The cut is made along section line II in FIG. 2.
  • FIG. 2 shows the same exemplary embodiment in a longitudinal section along the line II-II in FIG. 1.
  • the pressure accumulator 1 has a tubular, for example cylindrical, base body 2 with a wall 3, the inside 31 of which delimits a storage space 4 for the medium, for example fuel under high pressure.
  • the base body 2 or the storage space 4 extend in the direction of a longitudinal axis L.
  • at least one bore 5 is provided which extends in the radial direction, that is to say perpendicular to the longitudinal axis L, through the wall 3 and the storage space 4 with the outside 32 of the Wall 3 connects. The medium can be removed from the storage space 4 through the bore 5.
  • a curvature 6 is provided on the inside 31 of the wall 3, which extends in the direction of the axis L over a substantial part of the storage space 4 and preferably over the entire length of the storage space 4. 2, the curvature 6 is the difference by which the upper part 3a of the wall 3 as shown is thicker than the lower part 3b as shown. As is particularly clear in FIG. 1, the curvature 6 is continuously curved, that is to say it has no flat areas. The curvature of the curvature 6 has the opposite sign as the curvature of the remaining part of the inside 31 of the wall 3. For a better understanding, the contour K, which would result from a precisely circular cross section of the storage space 4, has been added with dashed lines ,
  • transition area 61 between the curvature 6 and the rest of the inside 31 of the wall 3 is rounded off, so that there are no edges here and the stresses are also kept low in these areas.
  • the curvature 6 is arranged with respect to the circumferential direction in such a way that the bore 5 opens symmetrically in the center of the curvature 6 into the storage space 4.
  • the curvature of the curvature 6 does not have to be constant either. It is essential, however, that the curvature has a finite value and a sign other than the curvature of the rest of the inside 31, that is to say the curvature 6 must extend into the storage space 4. In addition, it is essential that the entire bore 5 opens into the storage space 4 within the bulge 6, that is, the mouth of the bore 5 into the storage space 4 must be completely covered by the bulge 6.
  • this height H of the curvature 6 which means its maximum deviation from the contour K in the radial direction, it has proven to be advantageous in practice if this height H is between 5% and 30% of the inside diameter D of the storage space 4.
  • the pressure accumulator 1 usually has a plurality of bores 5. In the first exemplary embodiment, these are then arranged one behind the other so that each of the bores 5 opens into the storage space in the center of the arch 6 as described above.
  • the pressure accumulator 1 Due to the curvature 6 according to the invention, the pressure accumulator 1 has an internal shape which is optimized with regard to the stresses. Due to the configuration of the curvature 6 protruding into the storage space 4 in the area which is critical with regard to the stresses, where the bores 5 open, this area remains in the region of the compressive stresses when pressure is applied. In known pressure accumulators, tangential stresses, ie tensile stresses, are generated directly when pressure is applied. In the embodiment according to the invention, the transition into the area of tensile stresses takes place only at significantly higher loads. As a result, the pressure accumulator 1 according to the invention can be exposed to significantly higher internal pressures even under dynamic loads.
  • the pressure accumulator 1 Due to the internal shape of the pressure accumulator 1 according to the invention, this can be in the Compared to known memories are exposed to a multiple of the internal pressure. On the other hand, with the same internal pressure as in known accumulators and with the same volume of the storage space, the accumulator according to the invention can be designed to be significantly slimmer, that is to say with a smaller thickness of the wall 3.
  • the curvature 6 preferably extends over the entire length of the storage space 4, so that the inner profile, which means the cross section of the storage space 4, is the same over the entire length of the base body 2. This means a considerable simplification of the manufacturing process.
  • the base body 2 of a pressure accumulator 1 according to the invention can be produced in a simple manner by extrusion, casting or broaching using a tool adapted to the desired cross section. Subsequent local internal processing on the inside 31 of the wall 3 is no longer necessary.
  • Another advantage is that the bores 5 can be drilled at any point with respect to the longitudinal direction, which significantly increases the flexibility with regard to the adaptation to different circumstances.
  • a further advantageous measure consists in providing a flattening 7 on the outside 32 of the wall 3 of the base body 2, which is arranged and designed such that the bore 5 opens into a flat surface on the outside 32.
  • This has the advantage that devices 10 (indicated by dashed lines in FIGS. 1 and 2) that are to be acted upon by the medium from the pressure accumulator, for example components of the fuel injection system, can be mounted directly on the base body 2, so that connecting lines are dispensed with can be.
  • the flat 7 extends over the entire length of the base body, so that the flat 7 forms a flat strip which extends essentially over the entire length Length of the base body 2 extends.
  • the holes 5 then open into this flat strip.
  • FIG. 3 shows a variant of the first exemplary embodiment in a representation analogous to FIG. 1.
  • the outer shape of the base body 2 is not cylindrical, but has two flat strips 8 which extend essentially over the entire length of the tubular base body 2.
  • the flat strips 8 are arranged such that the bores 5 open outside the flat strips 8 into the outside 32.
  • Additional devices 9 can be arranged on this strip 8. Heavy oil is typically used as a fuel in large diesel engines. The heavy oil has to be heated in order to achieve the necessary viscosity. For this purpose, heating can be provided as an additional device 9 on one of the flat strips 8 in order to supply heat to the heavy oil in the storage space 4.
  • FIG. 4 shows a cross section through a second exemplary embodiment of a pressure accumulator 1 according to the invention in a representation analogous to FIG. 1. Only the differences from the first exemplary embodiment are discussed below. The explanations in connection with the first exemplary embodiment apply analogously to the second exemplary embodiment. In particular, the reference symbols have the same meaning.
  • FIG. 4 several, namely three, of the arches 6 according to the invention are provided on the inside 31 of the wall 3.
  • Each of the arches 6 extends over a substantial part of the length of the storage space 4, preferably over its entire length.
  • the curvatures 6 are evenly distributed over the circumference of the inside 31.
  • Several bores 5 are provided, each of which opens into the storage space 4 in the center of one of the arches 6.
  • Flats 7 are provided on the outside 32, which are arranged so that the holes 5 on the outside 32 open into a flat surface. Of course, it is also possible to distribute the bulges unevenly over the circumference.
  • the holes 5 for the removal of the medium from the storage space 4 are distributed over the circumference of the pressure vessel 1. As a result, more holes 5 can be provided. Furthermore, the medium can be led away in different directions without great effort.
  • the flats 7 extend over the entire length of the base body 2, so that the flats 7 each form a flat strip 8, which extends essentially over the entire length of the base body 2.
  • the holes 5 then each open into one of these flat strips 8.
  • Fig. 6 shows a variant in which the outer surface 32 of the wall 3 forms a cylinder jacket.
  • the device 10 (FIGS. 1, 2), as explained above, can be attached directly to the outside 32 of the wall 3.

Furthermore, it is also possible to attach a flange, preferably to one of the flats 7 or one of the flat strips 8. In principle, all known connection and fastening options are suitable.
  • a third embodiment of the invention is used to describe a form of realization which is particularly preferred from a practical point of view for the curvature 6 according to the invention which extends into the storage space 4. It goes without saying that the explanations relating to the first and second exemplary embodiments also apply analogously to the third exemplary embodiment and that the individual measures described can likewise be combined with or applied to the third exemplary embodiment.
  • Fig. 7 shows a cross section through the third embodiment.
  • the difference from the first and the second exemplary embodiment lies in the design of the storage space 4.
