Patent ID: 7557472

Claim:
A valve drive for a gas exchange valve in an engine comprising: a magnetic rotor: a rotor section rositioned at a distance from the gas exchange valve, extends in a longitudinally movable manner inside a bushing of a stator provided with a current coil, the stator has a tooth area forming a magnetic frame, and one end of the rotor projects out from the stator in a direction of the gas exchange valve, and upon the excitation of the current coil, the rotor activates the gas exchange valve, wherein the rotor ( 12 ) is a flat-body slide valve and located in an area of the rotor section and constructed in the stator ( 1 ) as a vertically moved rotor plate ( 11 ) in which several magnetic rarts ( 21 ) are oriented, in several planes and a base area of the stator ( 1 ) is oriented towards the gas exchange valve ( 4 ), at least one bushing ( 8 ) is adjusted to the cross-sectional contour of the rotor plate ( 11 ), and through the bushing at least one rotor bar ( 14 ) connects the rotor plate ( 11 ) with a coupling element ( 17 ).
