Abstract

Für eine Gaswechselventil-Steuerung für Brennkraftmaschinen mit einem mit Gasfedern ausgerüsteten elektromagnetischen Aktuator mit einem das Gaswechselventil antreibenden, zwischen hubbeabstandeten Schaltmagneten gegen Gasfedern oszillierend angeordneten Anker wird vorgeschlagen, dass der als Trennkolben zwischen den Gasfedern dienende Anker reibungsfrei in einem geschlossenen Anker-Hubraum beweglich angeordnet ist, und dass ein den Anker-Hubraum einschließlich die benachbarten Schaltmagnete umschließendes, gehäuseartiges Joch zwischen den Schaltmagneten eine Vorrichtung aufweist, die einer Verkürzung des jeweiligen magnetischen Kreises des jeweiligen Schaltmagneten dient.

Figure 00000001
For a gas exchange valve control for internal combustion engines with an electromagnetic actuator equipped with gas springs with an armature which drives the gas exchange valve and which is arranged to oscillate between stroke-spaced switching magnets against gas springs, it is proposed that the armature serving as a separating piston between the gas springs be arranged to move smoothly in a closed armature displacement , and that a housing-like yoke enclosing the armature displacement including the adjacent switching magnets has a device between the switching magnets which serves to shorten the respective magnetic circuit of the respective switching magnet.
