Abstract (en)
[origin: US2001017113A1] A gas exchange valve control for internal combustion engines includes an electromagnetic actuator equipped with gas springs. The gas exchange valve control has an armature, which drives the gas exchange valve and is arranged to oscillate between stroke-separated switching magnets against the gas springs. The armature serving as the separating piston between the gas springs is moveable without friction in a closed armature stroke space. A housing-like yoke, which encloses the armature stroke space, including the adjacent switching magnets, exhibits between the switching magnets a device which serves to shorten the respective magnetic circuit of the respective switching magnet.
