  • the invention also relates to a fuel injector or a high-pressure fuel accumulator equipped with an electromagnetic valve as defined in the preamble of claim 1 ( EP-A-1,967,726 ).
  • Such an electromagnetic valve is inter alia used to control the fuel pressure in the control chamber of a fuel injector, for example an injector of a common rail injection system.
  • a fuel injector for example an injector of a common rail injection system.

  • an electromagnetic valve for controlling a fuel injector comprises a housing receiving an electromagnet, and a movable armature biased by the force developed by a valve spring, and a shutter member made on the armature or cooperating with it and pushed against a seat of the electromagnetic valve by the force developed by the valve spring.
  • the electromagnet is used to open and close the electromagnetic valve to thereby regulate the fuel outlet of the control chamber.
  • the armature has a raised portion in the form of a flange on its side facing the electromagnet and which is applied against a housing part surrounding the electromagnet in the final position when the electromagnet is attracted; the height of this flange defines the residual air gap between the electromagnet and the front face of the armature.
  • the document DE 10 131 199 A1 discloses an electromagnetic valve whose front face of the armature or the polar surface of the electromagnet rotated correspondingly, comprises a raised portion of a non-magnetoconductive material, for example a coating defining the minimum distance between the magnetoconductive surfaces of the electromagnet and the armature.
  • the present invention relates to an electromagnetic valve of the type defined above, characterized in that a stop disk is provided between the end face of the armature turned towards the armature and the end face opposite the armature, this thrust disk being made of a magnetized or magnetizable material, in particular a ferromagnetic material.
  • the electromagnetic valve is characterized in that the bearing surface of the stop disc is reduced by at least one clearance or cut. Such clearance or cutting, makes it possible to reduce the resulting contact surface between the abutment disc and the frame, in a simple and economical manner.
  • the invention also relates to a fuel injector equipped with such an electromagnetic valve or a high-pressure fuel accumulator equipped with such an electromagnetic valve as a pressure regulator.
  • the electromagnetic valve has the advantage that for the same dimension, the valve provides a greater magnetic force and makes it possible to better adapt the hydraulic damping to the requirements to be met by the valve.
  • electromagnetic The choice of reinforcement, thrust disc and armature materials avoids magnetic bonding or at least the choice of the valve spring, reduces the effects of magnetic bonding.
  • the polar surface not covered by the stop disc and its distance are available as adjustment parameters of the magnetic bonding effect.
  • a magnetic short circuit is avoided. This can be done for example by the thickness of the stop disc or the shape given to it.
  • Another advantage of the electromagnetic valve according to the invention is to have another magnitude of influence in the form of the thrust disk to better adapt the magnetic force and dynamics to the requirements of the solenoid valve.
  • the armature in at least one predefined operating state of the electromagnetic valve, is applied at least with a surface portion, without leaving an air gap, against the abutment disk of the electromagnetic valve.
  • the entire valve electromagnetic valve can be dimensioned more reduced by the larger magnetic forces compared to those of an electromagnetic valve of the same dimensions according to the state of the art, which can be used to have a better dynamic of the electromagnetic valve and / or to reduce the bulk.
  • This can be used to have a higher power density of the engine and / or better emission factors and / or better protection against accidents, including safety in the event of collision with a person falling on the bonnet of the engine .
  • the material consumption and thus the cost of the electromagnetic valve are reduced.
  • the electromagnetic valve is characterized in that the stop disk protrudes laterally from the armature, and in at least one operating state, it is applied against the casing and thus transmits at least in part the forces shock to the case.
  • the kinetic energy during the shock of the armature is transmitted at least in part to the housing.
  • This development makes it possible to reduce the mechanical forces exerted on the reinforcement, which can thus be made of a material that is less hard than that of the stop disc and optimized from the point of view of its magnetic properties for the reinforcement. It avoids or at least greatly reduces premature wear of the armature through this transfer at least partial efforts during the shock of the armature through the thrust disc to the housing.
  • the electromagnetic valve is characterized in that the stop disk is placed between the inner pole of the armature and the armature.
  • the arrangement between the inner pole of the armature and the magnetic armature in the case of a one-piece abutment disk has, moreover, the advantage of a smaller diameter abutment disk and thus of part of having only a small surface of the frame that is covered, thus greatly reducing the magnetic bonding and secondly, this disk is made with little material which corresponds to an economical solution.
  • the electromagnetic valve is characterized in that the stop disc is placed between the outer pole of the armature and the armature.
  • This solution has the advantage of not installing additional parts at the connection points between the armature and the valve closure member or to produce an additional part at this point. This facilitates the realization of the combination of the armature and the valve closure member as well as the mounting of the electromagnetic valve.
  • the electromagnetic valve is characterized in that the stop disc only partially covers an inner pole, adjacent or an outer pole of the armature for its end face facing the stop disc.
  • the contact area between the abutment disk and the armature is reduced. This reduces any residual magnetic bonding and, moreover, thanks to the only partial covering of one or both poles of the armature, the magnetic field lines are concentrated at the level of the abutment disk to arrive at a higher saturation. local magnetic and at a higher energy density. This makes it possible to further optimize the magnetic forces.
  • the electromagnetic valve is characterized in that at least one clearance or cut is made in the form of an orifice, in particular circular.
  • Such orifices are made economically and simply, for example by press cutting into the stop disc; they reduce the resulting contact area and thus the magnetic bonding.
  • the clearance or the cut is made in the form a slot, preferably centered.
  • This slot may be a variant of a circular orifice of the stop disc or be provided in addition to at least one such circular orifice; this slot preferably has a length which extends over a large part of the diameter of the stop disc. This slot further reduces the eddy currents in the section of the thrust disk and improves the dynamic switching behavior of the electromagnetic valve.
  • the stop disc completely covers the adjacent inner pole or the outer pole of the armature at its front surface facing the stop disk or overflowing its poles.
  • This shape given to the stop disc section allows the magnetic field lines at the stop disc, to better follow the contour at the transition between the armature, the stop disc and the armature, which translates by a higher overall magnetic force of the electromagnetic valve.
  • part of the kinetic energy produced during the impact of the armature can be discharged into the housing and thus discharge the magnetic core.
  • a fuel injector equipped with an electromagnetic valve according to the invention offers the advantage vis-à-vis the state of the art, to increase its switching speed and sealing of the fuel injector; this also reduces the current required for control. It is thus possible to better dose injected quantities and increase the control accuracy of the fuel injector.
  • the increase of the switching speed and the reduction of the consumed current in addition increase the possibilities of application of such a fuel injector.
  • a high-pressure fuel accumulator (common rail) equipped with an electromagnetic valve according to the invention to ensure the regulation of the pressure, offers the advantage of improving the sealing of the valve, especially at high pressures, because the higher magnetic force makes it possible to set a larger closing holding force for the shutter member of the electromagnetic valve.
  • Vis-à-vis future high pressure fuel accumulators which will be designed for pressures greater than 2000 bars, this offers a definite advantage.
  • the electromagnetic valve will be functionally very robust vis-à-vis the particles.
  • the electromagnetic valve according to the invention makes it possible to increase the accuracy of the regulation of the pressure in the high-pressure fuel accumulator.
  • the figure 1 shows an exemplary embodiment of an electromagnetic valve as it is used multiple times in the fuel injectors.

  • the annular volume 14 is delimited by the lower part 1 of the housing, as well as the room valve 5 and this volume is connected by an inlet passage, throttled 15 to a control chamber 16.
  • the control chamber 16 is delimited by the valve member 5 and by a valve piston 17. Facing the face front of the valve piston 17 delimiting the control chamber 16, the valve member has a constricted outlet passage 18. This constricted outlet passage 18 is closed by a valve ball 19 when the electromagnetic oupape is not actuated.
