Definitions
- the invention relates to a preamble of claim 1
- Valve control for internal combustion engines with one equipped with gas springs electro-magnetic actuator in which one with a gas exchange valve in drive connection standing anchor between a closing magnet and an opening magnet is arranged to oscillate against restoring forces of the gas springs, the gas springs separated from each other by means of the armature from a chargeable Store a gas metered via controllable valves and from the gas springs Gas is drained via controllable drain valves.
- Such a valve control is known for example from US 5,611,303, the interaction of metering valves and drain valves with regard to a stroke adjustable actuator is tuned. This configuration also requires Formation of the gas springs in a tube arranged as a piston, the center of an anchor section is divided.
- the invention has for its object to the generic valve control simple design so that variable spring characteristics in connection with controlled stroke damping can be achieved.
- the electro-magnetic actuator according to the invention with a pressure-controlled actuator Armature or separating piston with deenergized closing magnet and opening magnet
- the Separating piston or armature pressure-controlled when the internal combustion engine is switched off The closed position of the gas exchange valve is arranged, the on 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 shown schematically in the drawing described.
- a valve controller 1 for an internal combustion engine includes one Actuator 2 with gas springs 3, 4, one with a gas exchange valve 5 in drive connection standing armature 6 between a closing magnet 7 and a Opening magnets 8 are arranged oscillating against restoring forces of the gas springs 3, 4 is.
- the gas springs 3 and 4 are from a rechargeable memory 9 Lines 9 'and 9 "each meter a gas via controllable valves 10. Furthermore, gas can be released from the gas springs 3 and 4 via controllable drain valves 11.
- the Armature 6 as a tightly slidably arranged in a cylinder 12 of the actuator 2
- Separating piston 13 is formed between the two gas springs 3 and 4 and that the Metering valves 10 and the drain valves 11 depending on the load ranges of the Internal combustion engine controlled to adjust adjusted spring characteristics, the drain valves 11 additionally controlling a damped stop the separating piston 13 and the armature 12 against the closing magnet 7 and against serve the opening magnets.
- Actuator 2 of armature 6 even when the closing magnet and opening magnet are not energized be operated under pressure control.
- Control of the actuator 2 can be used so that the separating piston 13 or armature 12 when switching off the internal combustion engine pressure-controlled in the closed position of the Gas exchange valve 5 is arranged, the struck on the closing magnet 7 Separating piston 13 is held on the closing magnet 7 by means of a permanent magnet 14 is.
