| 摘要 |
The invention relates to a valve drive for a gas exchange valve ( 4 ) in a power engine or a processing engine, with a magnetic rotor ( 12 ) which, along with a rotor section positioned at a distance from the gas exchange valve ( 4 ), extends in a longitudinally movable manner inside a stator ( 1 ) provided with a current coil ( 18 ), so that one end of the rotor ( 12 ) projecting out from the stator ( 1 ) activates the gas exchange valve ( 11 ) upon the stimulation of the current coil ( 18 ). The rotor ( 12 ) is, in the area of the rotor section, preferably designed in accordance with the type of a flat-body slide valve as a vertically moved rotor plate ( 11 ), in which several level individual magnetic parts ( 21 ) are aligned.
