Definitions

  • Such a valve control is known for example from US 5,611,303, the interaction of Zumess valves and drain valves with regard to a stroke-adjustable actuator is tuned.
  • This embodiment also requires the Forming the gas springs in a tube arranged as a piston, the center of is divided an anchor section.
  • electro-magnetic actuator according to the invention with pressure-controlled operable Anchor or separating piston with no-current closing magnet and opening magnet arises in an advantageous embodiment of the invention further that the Separating piston or armature when switching off the engine pressure controlled in Closed position of the gas exchange valve is arranged, wherein the closing magnet struck separating piston or armature by means of permanent magnets on Closing magnet is held.
  • the invention is based on an embodiment schematically illustrated in the drawing described.
