Abstract

Für eine Ventilsteuerung für Brennkraftmaschinen mit einem mit Gasfedern ausgerüsteten elektro-magnetischen Aktor, bei dem ein Anker gegen die Gasfedern zwischen einem Schließmagneten und einem Öffnungsmagneten oszillierend angeordnet ist, wird vorgeschlagen, dass der Anker als ein in einem Zylinder des Aktors gleitbeweglich dicht angeordneter Trennkolben zwischen beiden Gasfedern ausgebildet ist und dass den Gasfedern zugeordnete Zumess-Ventile und Ablass-Ventile in Abhängigkeit von Lastbereichen der Brennkraftmaschine gesteuert der Einstellung angepasster Federkennlinien dienen, wobei die Ablass-Ventile zusätzlich der Steuerung eines gedämpften Anschlages des Trennkolbens bzw. des Ankers gegen den Schließmagneten und gegen den Öffnungsmagneten dienen.

Figure 00000001
For a valve control for internal combustion engines with an electro-magnetic actuator equipped with gas springs, in which an armature is arranged to oscillate against the gas springs between a closing magnet and an opening magnet, it is proposed that the armature be used as a separating piston which is slidably movably arranged in a cylinder of the actuator Both gas springs are designed and metering valves and drain valves assigned to the gas springs are used to adjust adjusted spring characteristics in dependence on load ranges of the internal combustion engine, the drain valves additionally controlling a damped stop of the separating piston or armature against the closing magnet and serve against the opening magnet.
