Abstract
An electromagnetic valve actuating mechanism for an internal combustion engine has an axially displaceable control element with an armature plate, for opening or closing a valve. Two solenoids are arranged behind one another in the displacement direction and spaced with respect to one another. One solenoid is arranged on the side of the armature plate close to the valve and the other is on the side away from the valve. Two springs are arranged behind one another in the displacement direction, one of the springs being arranged on the side of the armature plate close to the valve and the other being arranged on the side away from the valve. The control element, which is held in a neutral position when the solenoids are currentless, is deflectable from its neutral position by energizing the solenoids. An adjusting element, which rests on the end of one of the two springs away from the armature plate, is adjustable to change the prestressing of the springs and the location of the neutral position of the control element. The adjusting element, which is displaceably arranged in the displacement direction, is displaceable via an actuating device during the operation of the valve actuating mechanism, for adjusting of the neutral position.
