Definitions

  • An electromagnetic actuator for actuating a gas exchange valve on a piston internal combustion engine consists in essentially of two spaced apart Electromagnets, the pole faces of which face each other and between which a gas exchange valve to be actuated acting anchor against the force of at least one return spring between an open position and a closed position for the gas exchange valve to be moved back and forth is.
  • One of the electromagnets serves as Closing magnet through which the gas exchange valve counteracts the force the opening spring is held in the closed position during the other electromagnet serves as an opening magnet, through which the Gas exchange valve via the armature against the force of the assigned Closing spring is held in the open position.
  • the arrangement is such that the Anchor itself in a middle position between the two pole faces located. With alternating energization of the two The armature then comes against the electromagnet Force of a return spring on the pole face of the current supplied and thus catching electromagnets to the system. Becomes the holding current is switched off at the respective holding electromagnet, then the armature is driven by the force of the return spring accelerated towards the other electromagnet, the one corresponding during the anchor movement high catch current is applied so that after overshoot about the middle position of the armature by the magnetic force against the force of the electromagnet which is now catching Return spring comes to rest.

This leads to the anchor in the final phase shortly before hitting the pole face of the catching electromagnet with increasing Acceleration moves, causing a hard impact the anchor comes on the pole face, which in many ways is disadvantageous, for example, by body and airborne sound excitation and the resulting noise. Around One tries to avoid this by means of a corresponding regulation the catching current shortly before the anchor hits the To reduce the pole area of the respective capturing electromagnet, whereby the approach of the armature is detected by a sensor system becomes.
