Definitions

  • DE 196 50 865 A1 refers to a solenoid valve for controlling the fuel pressure in a control chamber of an injection valve, such as a common rail high-pressure accumulator injection system. About the fuel pressure in the control chamber, a stroke movement of a valve body is controlled with an injection port of the injection valve is opened or closed.
  • the solenoid valve comprises an electromagnet, a movable armature and a valve member moved with the armature and acted upon by a valve closing spring in the closing direction and cooperating with the valve seat of the valve member to control the fuel output from the control chamber.
  • the fuel injectors used must switch very precisely. This means that the injection process for a same drive the same length, i. has time duration, so that the accuracy of the metered amount of fuel in the respective combustion chamber of the internal combustion engine can be maintained.
  • solenoid valve concepts having an anchor plate are particularly sensitive to the switching action, i. the opening of a closing element of a control chamber, are excited by the pressure oscillations.
  • a Abberichtbericht which induces the pressure oscillations.
  • the main influencing variables on the actual circuit process are these pressure oscillations with respect to their amplitude as well as with regard to the direction as well as the delay of the resulting pressure wave or the vapor or gas components in the Ab Kunststoffmaschinen.
  • the bores run radially in the armature guide, for example in such a way that in these embodiments, no measures are taken to purposely remove the control quantity from the control chamber.
  • the diverted amount flows through radially arranged holes in the armature guide, so that the Abêt Victoria bounces on the outer boundary.
  • the outer boundary is usually given by the inside of the valve clamping screw. Due to the impact on the outer boundary arise undefined turbulence, which cause the Ab Kunststoffell meets with each actuation of the armature assembly of the solenoid valve slightly different on the anchor plate and thus each valve switching is subject to different constraints.
  • the abutment thrust i. the controlled from the control room when opening the valve seat control amount be impelled a twist.
  • This twist ensures that the maximum pressure amplitudes do not occur in the region of the armature or that the main steam component, which is contained in the Abêtmenge is directed into non-critical areas.
  • non-critical is understood to mean that disturbances such as pressure oscillations or undefined liquid / vapor mixtures in the amount of spill in the areas to which they are directed after opening the valve seat have no effect on the function of the solenoid valve, i.
  • a solenoid valve is insensitive to external influences, such as the prevailing in the return region of a fuel injector return back pressure.
  • the return back pressure in the return region of a fuel injector is in the order of 0.4 to 1 bar, or in other areas.
  • the Ab Kunststoffstoss can flow out of the wall.
  • This has the consequence that the pressure surge occurring when opening the valve seat can be passed outside of the armature plate of the armature assembly of the solenoid valve.
  • the design of non-radially extending in the armature guide through holes which are preferably formed as holes in the armature guide, allow a radial or axial steering of the Ab tenuge.
  • non-radially extending passage openings in particular in the armature guide non-radially extending bores, can be formed either horizontally in the armature guide or with an elevation angle in the armature guide. Furthermore, it is possible on the inside of the valve tightening screw, with which the valve piece in which the control chamber is formed, is clamped to the injector to form wells in different geometries, which also impart a spin to the Abêtmenge that induced by the induced pressure oscillations the anchor plate remains subject to reproducible switching conditions.
  • a fuel injector 10 can be seen.
  • the fuel injector 10 is controlled by means of a solenoid valve 12.
  • the solenoid valve is accommodated on an injector body 14 of the fuel injector 10.
  • a high-pressure port 16 is connected; a low-pressure side return of the fuel injector 10 is indicated by reference numeral 18.
  • the solenoid valve 12 is by means of a magnetic clamping nut 20 on the injector 14 of the fuel injector 10 according to FIG. 1 attached.
  • the magnet assembly and the injector body 14 are executed substantially symmetrically to the injector axis 22 of the fuel injector 10.
  • the solenoid valve 12 comprises a magnetic core 24, in which a magnetic coil 26 is inserted.
  • the magnet coil 26 comprises a passage opening 30, in which a closing spring 28 is arranged.
  • the closing spring 28 is accommodated on a bolt 32.
  • the solenoid valve 12 includes an armature assembly 34 that includes an armature plate 36.
  • the anchor plate 36 comprises a sleeve-like projection, which in turn is guided in an armature guide 38.
  • the armature guide 38 is part of a valve piece 44.
  • the valve piece 44 is fixed by means of a valve clamping screw 40 to a shoulder 46 of the injector body 14.
  • a valve seat 42 is executed in the valve piece 44, in addition to the armature guide 38, in which the armature plate 36 is guided.
  • the valve seat 42 is executed in the valve piece 44, in addition to the armature guide 38, in which the armature plate 36 is guided.
  • the valve seat 42 is closed or released by the anchor plate 36, or its sle
  • a high-pressure chamber 48 Between the outer circumferential surface of the valve member 44 and the injector body 14 is a high-pressure chamber 48.
  • the high-pressure chamber 48 is sealed by a sealing ring 50.
  • a control chamber 54 is acted upon within the valve piece 44 by an inlet throttle 52 with fuel under system pressure.
  • the fuel passes through the already mentioned high pressure port 16 in the injector body 14 of the fuel injector 10.
  • system pressure is hereinafter understood a pressure level, for example, in a high-pressure accumulator injection system (common rail) in the high-pressure accumulator body (common rail) via a high-pressure pumping unit
  • a high pressure pump is generated and maintained.
  • the control chamber 54 which is acted upon by the inlet throttle 52 with fuel under system pressure, is bounded by the valve piece 44 and by an end face of a preferably needle-shaped injection valve member 56.
  • the preferably needle-shaped injection valve member 56 is in his in FIG. 1 not shown combustion chamber side seat, so that injection openings are closed in the combustion chamber of the internal combustion engine.
  • the preferably needle-shaped injection valve member 56 enters the control chamber 54 and at least one provided at the combustion chamber end of the fuel injector 10 injection opening in the combustion chamber of the internal combustion engine free, so that fuel is injected into this.
  • the solenoid 26 of the solenoid valve 12 is energized.
  • the armature plate 36 is tightened and the valve seat 42 is opened.
  • Control quantity flows out of the control chamber 54 via a discharge channel 58 extending through the valve piece 44 from the control chamber 54 and a discharge throttle 60 received therein.
  • the control quantity flows via at least one Abêtö réelle 62 in the armature guide 38 in the low pressure region of the fuel injector.
  • FIG. 2 shows an enlarged view of the armature assembly of a fuel injector.
  • the armature guide 38 is part of the valve piece 44, which via the valve clamping screw 40 in the injector body 14 (see illustration according to FIG. 1 ) is attached. If the magnetic coil 26 is energized, the armature plate 36 of the armature assembly 34 is attracted against the action of the closing spring 28 and the valve seat 42 is opened above the valve member 44.
  • the control chamber 54 via the drain passage 58 and the discharge throttle 60 taken therein shot amount shoots over the open valve seat 42 through the Abêtöff openings 62 in a designated by reference numeral 70 annulus.
  • This annular space 70 is bounded by an inner side 66 of the valve clamping screw 40 and the outer circumferential surface of the armature guide 38.
  • a diversion shock 64 with turbulence is created.
  • Under turbulences are understood there a directed flow having liquid and gas components and which acts on a bottom 68 of the armature plate 36 of the armature assembly 34. Since it is a Abgresmaschine 64 with turbulence, injection operations are not reproducible in the required precision.
  • the section A - A (compare illustration according to FIG. 2 ) illustrates the flowing into the annulus 70 Ab Kunststoffish 64 with turbulence.
  • 22 are in the armature guide 38 radially with respect to the injector 22 Ab Kunststoffö réelleen 62. These strictly radially oriented Ab Kunststoffö réelleen 62 are preferably designed as bores.
  • a Abgrescion 64 flows from entangled fuel into the annulus 70 a.
  • the annular space 70 is bounded by the inner side 66 of the valve clamping screw 40 on the one hand and the lateral surface of the armature guide 38 on the other.
  • the wall 72 on the inside of the valve clamping screw 40 with individual recesses or recesses in order to additionally impart a twist to the fuel flow emerging from the discharge openings 62.
  • the Abgresö réelleen shown in the section BB BB 62 in non-radial position 74 are also preferably carried out in the armature guide 38 of the valve member 44 as holes. Instead of the illustrated in the section B - B four at an angle of 90 ° to each other oriented Abêtö réelleen 62 and a lesser or greater number of Abêtö réelleen 62 are formed in non-radial position 74 in the armature guide 38. Of importance, that the Abgresö réelleen 62 each passing control amount a twist - as shown in section BB - is impressed, so that adjusts a system 78 of the fuel flow to the wall 72 of the valve clamping screw 40.
  • the cut-off openings 62 which are illustrated as being bores B-B and which are designed as bores, represent obliquely set bores which ensure a wall-shaped outflow of the control quantity. This means that the pressure impact occurring when opening the valve seat 42 can be passed outside of the anchor plate 36. This means that the conditions from one shift to the next shift are reproducible and there are fewer deviations between individual injection events.
  • FIG. 4 shows a further greatly enlarged reproduction of the armature assembly of the solenoid valve.
  • FIG. 4 shows the armature 36 of the armature assembly 34 is guided on the one hand in the armature guide 38 of the valve piece 44 and on the other hand provided with a bolt or pin 32.
  • Above the upper plane side of the armature plate 36 of the armature assembly 34 is the magnetic coil 26, which is embedded in a magnetic core, not shown here.
  • the armature plate 36 of the armature assembly 34 is acted upon by the closing spring 28 in the closing direction, so that the valve seat 42 is closed at the top of the valve piece 44. In this state, no fuel exits the drain passage 58 with outlet throttle 60 for pressure relief of the control chamber 54.
  • the angle of attack 84 may be formed variable in the radial direction of the Abêtö réelleen 62 is about 30 °.
  • the width of the annular space 70 which is bounded by the lateral surface of the armature guide 38 of the valve piece 44 and by the inner side 66 or the wall 72 of the valve clamping screw 40, can be a directed flow 76 - FIG. 4 shown - reach.
  • the angle of attack 84, the obliquely upward Abêtö réelleen 62, which are preferably made in this embodiment as holes in the armature guide 38 may also be different angles than the aforementioned 30 °. Also in FIG. 4 shown in section BB, formed in non-radial position 74 in the armature guide 38 of the valve member 44 and characterize the control amount that shoots into the annulus 70 in the Ab Kunststoffstosses a twist or a directed flow 76th on.
  • angle of attack 84 characterizes the geometry, in particular the surface of the anchor plate 36 of the armature assembly 34. The further the outer circumference of the surface of the anchor plate 36 protrudes into the annular space 70 or even covers it, the shallower the angle of attack 84 should be selected to prevent exposure of the underside 68 of the anchor plate 36 by the directed flow 76.
