Definitions

  • the invention relates to a preamble of claim 1 electromagnetic actuator for controlling a gas exchange globe valve Internal combustion engine, one being in drive connection with the lift valve Armature between stroke-spaced electromagnets against diametrical acting springs is arranged in a controlled oscillating manner and being in both Electromagnet-guided armature with a pot-like end stop damping device cooperates.
  • An actuator of the type described above is for example from EP-B 0 354 417.
  • the armature is both in the center closing as well as opening side with a piston-like extension for guidance formed with tight play in the respective pot magnet, with each of the extensions serves as an end stop damping device.
  • the plate-like design Anchor between the stroke-spaced electromagnets one each Damping chamber associated with the closing and opening side, which by means of a Anchor displacement enclosing sleeve is formed, with which the anchor over his The outer circumference interacts closely with friction.
  • the anchor described above has a relative due to the piston-like extensions large mass, so that a significant reduction in impact noise of the armature placed on the respective electromagnet is effective End stop damping device is required before this actuator all about a frictional seal between the sleeve and the Scope of the anchor plate is reached. Controlling this actuator is difficult and energy consuming.
  • the invention has for its object a generic actuator in its further develop mechanical structure such that with significantly reduced moving masses and the elimination of a mechanical friction Damping a simpler control with a lower energy level is achieved.
  • peripheral walls each anchor pot or the double pot anchor with within Coils cooperate with recesses arranged close to the coil in the respective coil core and also the stroke-dependent into the corresponding recesses of the Coil cores immersing peripheral walls of the armature pots with those in the Recesses associated with coil cores each have first choke points Form damping chambers.
  • the double-pot armature according to the invention can be used for faster magnetization have an anchor ring on the outside at the level of the anchor plate.
  • the invention is based on an actuator shown schematically in the drawing described.
  • the only drawing shows an electromagnetic actuator 1 for control a gas exchange lift valve 2 of an internal combustion engine, not shown 3, one with the shaft 4 of the lift valve 2 in driving connection Armature 5 between stroke spaced magnets 6 and 7 against diametrically acting springs 8 and 9 is arranged controlled oscillating and wherein the in two magnets 6 and 7 guided armature 5 with a pot-like end stop damping device 10 cooperates.
  • the height of the anchor pots 13, 14 can be chosen such that whose peripheral walls 16, 17 in the middle position of the armature 5 in the de-energized State of the magnets 6, 7 under the action of the diametrically acting springs 8, 9 already dip into the recesses 18 and 19.
  • One is preferred from the Drawing apparent pot height such that the anchor pots 13, 14 and the Double-pot anchor 5 with the respective peripheral walls 16, 17 depending on the stroke in immerse the corresponding recesses 18, 19 in the coil cores 6 ', 7' and thus the above-described first damping effect is achieved.
