Definitions

  • the invention relates to control valve arrangements on a control chamber, in particular of a fuel injector, with an electromagnetic actuator actuating the valve arrangement.
  • a nozzle needle is provided for controlling the injectors whose nozzle distal end formed in the manner of a plunger and displaceable in a control chamber which communicates via an inlet throttle with the high pressure side of the fuel injector and a Control valve assembly with the low pressure side of the fuel injector is connectable.
  • the control chamber is connected with the control valve arrangement closed only with the high pressure side of the fuel injector, while the pressure in the control chamber with open control valve assembly as a result of the then existing connection with the low pressure side drops.
  • the nozzle needle is pushed into its closed position.
  • the control chamber has an outlet channel which opens out to the low-pressure side of a valve body and which is controlled by the control valve arrangement.
  • the control valve arrangement has a sleeve-shaped closing body, which is displaceably arranged on a guide shaft which is identical to the outlet channel, wherein the annular gap between the outer circumference of the guide rod and the inner circumference of the sleeve-shaped closing body is designed as a virtually leak-free sealing gap.
  • the sleeve-shaped closing body acts with a seat concentric with the mouth of the outlet channel.
  • the invention provides that the control chamber pressure an elastically deformable or movable against elastic resistance part, which leads or bundles the magnetic field of the actuator loaded, wherein movement or deformation-dependent electrical or magnetic parameters of the actuator for determining correlated with the control chamber pressure operating times or parameters are evaluated.
  • the invention utilizes the insight that the control chamber pressure changes significantly at the beginning and at the end of the injection phase of a fuel injector.
  • an analogous to the control chamber pressure intervention in the magnetic field of the actuator by evaluating the time course of the electrical voltage or the electric current at the actuator of the operation of the fuel injector with high Precision recorded and monitored.
  • the actuator thus assumes a dual function by not only serving to actuate the control valve assembly but also as a sensor for the operating phases of the fuel injector.
  • the control valve arrangement according to the invention has a guide rod on a slidably guided sleeve-shaped closing body, which is connected to an armature of the actuator forming the electromagnet assembly. It is further provided that the fluid pressure present within the sleeve-shaped closing body can be removed via the guide rod to the deformable or movable part.
  • This part may be formed as a deformable or movable part of a rod axis radial bottom of a Polschuhan extract serving as an actuator solenoid. By deformation or displacement of this soil, the relative position of the pole pieces can be changed, at the same time the electrical or magnetic parameters of the electromagnet are changed.
  • 1 is a fragmentary axial section of a fuel injector
  • FIG. 2 is a diagram showing the time course of the nozzle needle stroke and the control chamber pressure
  • FIG. 5 shows an illustration of a further modification
  • FIG. 6 shows a further modified embodiment
  • FIG. 7 shows an additional variant
  • FIG. 8 shows a further variant.
  • a high-pressure chamber 2 and a low-pressure chamber 3 are arranged within an injector body 1. These two spaces are separated from each other by a valve piece 4.
  • the high pressure chamber 2 communicates via an inlet channel 5 with a high pressure fuel source, not shown, for fuel, usually a so-called common rail.
  • the low-pressure space 3 is connected via a non-illustrated return line or the like to a fuel tank or the like.
  • the high pressure chamber 2 is connected via injection nozzles, not shown, with the combustion chamber of an internal combustion engine, also not shown.
  • the injection nozzles are controlled in a known manner by means of a nozzle needle, of which in Fig. 1, only the nozzle-distal end, which is designed as a plunger 6, is shown.
  • the plunger 6 is arranged displacer-effective in a control chamber 7 arranged in the valve piece 4.
  • This control chamber communicates via an inlet throttle 8 with the high-pressure chamber 2 and via an outlet throttle 9 with the low-pressure chamber 3, wherein the outlet throttle 9 is controlled by means of a control valve assembly 10. If the outlet throttle 9 is shut off by means of the control valve arrangement 10 and the nozzle needle is in its closed position, the same high pressure arises in the control chamber 7 as in the high-pressure chamber 2, with the result that the plunger 6 in FIG. 1 is pressed downwards is and the associated nozzle needle is held in its shut-off the injectors closing position.
  • the control valve assembly 10 has a sleeve-shaped closing body 11, which is tensioned by a closing spring 12, which is designed as a helical compression spring against a concentric to the outlet port of the flow channel 9 seat.
  • the seat is designed as a flat surface on which the sleeve-shaped closing body 11 is seated with a line-shaped annular edge. In principle, however, a differently shaped seat may be provided.
  • the sleeve-shaped closing body 11 is axially displaceably guided on a guide axis 13, which is equiaxial to the longitudinal axis 100 of the injector body 1, wherein the annular gap between the inner periphery of the closing body 11 and the outer circumference of the guide rod 13 is formed as a virtually leak-free throttle gap.
  • the pressure chamber 14 formed within the closing body 11 which communicates with the control chamber 7 via the outlet channel 9, and accordingly the same fluid pressure as the control raum 7 has shut off from the low-pressure chamber 3.
  • a star-shaped armature 15 of an electromagnet arrangement 16 is arranged, which is provided as an actuator for actuating the control valve arrangement 10.
  • the solenoid assembly 16 has in a known manner a magnetic coil 17, which is arranged within a concentric to the guide rod 13 Polschuhan extract with an annular outer pole 18 and an annular inner pole 19. If the magnetic coil 17 is energized electrically, the armature 15 is magnetically attracted by the poles 18 and 19, so that the closing body 11 is lifted against the force of the closing spring 12 from its seat and the control valve assembly 10 is opened.
  • the electromagnetic parameters of the solenoid assembly 16 changes such that the closing times of the nozzle needle by appropriate evaluation of the electric current-voltage curve at the solenoid 17 can be detected.
  • the electromagnet arrangement 16 also takes over
  • the guide rod 13 has the task of a control element for changing parameters of the electromagnet arrangement 16.
  • FIG. 3 shows a first embodiment of a possibility of changing the parameters of the solenoid assembly 16.
  • the pressure of the pressure chamber 14 dependent axial force of the guide rod 13 is removed to an elastically bendable bottom 21, which forms part of the Polschuhan extract and with the poles 18 and 19 is connected.
  • the air gap between the inner pole 19 and the armature 15 changes, that is, with an increase in the pressure in the control chamber 7 and the associated increase in pressure in the pressure chamber 14, the air gap between the armature 15 and inner pole 19 is increased.
  • the control chamber pressure increases immediately after the closing time of the nozzle needle, at this time increases the force acting on the bottom 21 axial force of the guide rod 13 and causes an increase in the air gap between the inner pole 19 and armature 15. If there is a residual flux in the magnetic circuit at this time, Thus, the enlargement of the aforementioned air gap causes a change in the coil voltage (at vanishing coil current) or a change in the coil current (at vanishing coil voltage). If there is no sufficient residual magnetic flux, the solenoid 12 is energized weakly before the expected closing time of the nozzle needle to re-establish magnetic flux. The degree of energization is chosen so low that the closing body 11 remains in its closed position.
  • the bottom 21 is supported stationary on its side remote from the inner pole 19 side.
  • the outer pole 18 is arranged separately from the bottom 21 stationary in the injector body 1, wherein between the bottom 21 and the outer pole 18, an air gap 22 remains. This air gap changes as a function of the axial force of the guide rod 13.
  • the associated changes in the magnetic flux of the solenoid assembly 16 thus in turn open up the possibility of accurately detecting the closing time of the nozzle needle.
  • the inner pole 19 and the outer pole 18 form a pole shoe arrangement which is separate from the flexible base 21 and whose bridge region is formed between the poles 18 and 19 with a comparatively small cross-section.
  • the embodiment of FIG. 6 differs from the embodiment of FIG. 5 essentially only in that the flexible bottom 21 rests on a ring land on the back of the inner pole 19 and an elastic gap 24 is changed in elastic bending of the bottom 21. Functionally, the embodiments of the embodiment of FIG. 5 thus apply to the embodiment of FIG. 6.
  • This web 25 is provided in the example of FIG. 7 on the side facing away from the armature 15 end face of the magnetic coil 17.
  • the flexible bottom 21 is arranged and designed such that it rests on vanishing axial force of the guide rod 13, that is at a correspondingly low pressure in the control chamber 7 and in the pressure chamber 14, on the facing end faces of the poles 18 and 19.
  • FIG. 8 A functionally similar embodiment is shown in Fig. 8. This embodiment differs from the embodiment according to FIG. 7 only in that the non-magnetic web 25 'is arranged on the side of the magnet coil 17 facing the armature 15. If the guide rod 13 is axially free of force, the bottom 21 is again on the facing end faces of the poles 18 and 19, and with a corresponding axial force of the guide rod 13, the air gap 26 'is formed at the inner pole.
