Definitions

  • the present invention relates to an actuator electromechanical valve control for combustion engine internal.
  • valve 110 which comprises mechanical means, such as springs 102 and 104, and electromagnetic means with two electromagnets 106 and 108, for control the position of valve 110 by means of signals electric.
  • the tail 113 of the valve 110 is applied against the rod 112 of a plate magnetic 114 located between the two electromagnets 106 and 108.
  • valve 110 alternates open positions or closed, called switched, with transient movements between these two positions. Thereafter, we will call “state switched” state of an open or closed valve.
  • the actuator 100 requires the use of a plate magnetic 114 of high mass due, in particular, to its thickness Sp important. This thickness is generally equal to the width Se of the branches of the electromagnets to obtain a optimal actuator operation. Indeed, the branches of the electromagnet and the plate thus form a circuit magnetic of constant section.
  • Figure 2 is a diagram showing the evolution of the effort electromagnetic (on the ordinate) as a function of the value of the air gap (on the abscissa).
  • the present invention overcomes the disadvantage mentioned above.
  • a valve actuator for a motor internal combustion comprising at least one electromagnet and one magnetic plate whose movement controls the movement of the valve which is characterized in that the parameters of the electromagnet and the plate are such that at least part of the magnetic circuit formed by the electromagnet and by the plateau is in a state of magnetic saturation when the magnetic plate is located near the electromagnet.
  • the parameters allowing to obtain the saturation of minus part of the magnetic circuit are in particular the parameters of the material constituting the plate or the electromagnet, and / or the shape, and / or the dimensions of this plate and / or electromagnet.
  • said parameters are such that the plateau (or electromagnet) is in a state of magnetic unsaturation when it is far from the electromagnet.
  • said parameters are such that the state of magnetic saturation, in particular of the plateau, is product for an air gap between 0 and at most 1 millimeter.
  • the invention relates generally to a valve actuator for internal combustion engine comprising at least one electromagnet and a magnetic plate whose movement controls the movement of the valve, which is characterized in that parameters of the electromagnet and plate are such that at least part of the magnetic circuit formed by the electromagnet and the plate is in a state of magnetic saturation when the magnetic plate is at proximity to the electromagnet.
  • said parameters are such that the magnetic circuit is in the state of magnetic unsaturation when it is far from the electromagnet.
  • the parameters are such that at least part of the circuit magnetic is in the state of magnetic saturation for a air gap between 0 and 1 millimeter maximum.
  • Parameters of the electromagnet and the plate include, according to one embodiment, parameters relating to the shape and / or dimensions and / or nature of the material (or materials) constituting the plate and the body of the electromagnet and / or the intensity of the current flowing through the solenoid coil.
  • the thickness of the plate is such that this plateau is magnetically saturated near the electromagnet.
  • the magnetic plate has for example at least a narrowed portion intended to be saturated when this tray is located near the electromagnet.
  • the material composing the plateau has a lower saturation threshold than that of material composing the body of the electromagnet.
  • the actuator comprises a regulator controlling the current in the electromagnet.
  • the invention also relates to a combustion engine. internal comprising at least one valve according to any one of the preceding claims.
  • the magnetic plate 114 present at its ends and at its center a thickness h of the same order of magnitude as the width Se of the end branches 140 and 142 of the magnetic circuit of the electromagnet 108 (or 106).
  • the plate has parts 144 and 146, of thickness h 'substantially smaller than the thickness h.
  • the magnetic plate 114 has a shape such that it constitutes a constriction for the magnetic flux 150 generated by the electromagnet 108, so as to concentrate it in these constrictions.
  • the magnetic flux 150 being conservative, the fact reducing the section of the tray 114 in places allows concentrate the magnetic induction in these parts 144 and 146 of thickness h '. So magnetic induction has a high value in the narrowed parts and so we can get a saturation of the material in these parts 144 and 146.
  • the magnetic plate 114 has a constant thickness h ′. We can thus saturate the entire magnetic plate. In addition, the mass of the plateau is even more reduced, which further reduces the energy dissipated, so the noise. In addition, with a reduced mass, the due to its low inertia, the platform can be accelerated better at the start of its race, when it is still far from the electromagnet which attracts it
  • the body of the electromagnet is as saturated when the air gap is small.
  • a regulation in combination with the invention This regulation will be facilitated by a better linearity of the force attraction, allowing easier control of the platform when it approaches the electromagnet.
  • curve 41 illustrates the variation of the force as a function of the value of the air gap for an actuator according to the invention, while the curve 42 corresponds to a conventional actuator.
  • Curve 41 is linearizes when approaching the electromagnet, when the air gap tends towards zero, while curve 42 increases so hyperbolic.
