Abstract
An electromagnetically operating device for actuating a valve comprises a single solenoid cooperating with an armature which cooperates by a crank system with a shaft which, in turn, is cooperating by a crank system with a valve. The fully open position and the closed position of the valve is defined by the stretched position or the folded position of its crank system. The armature, in the fully open position and in the closed position of the valve, is substantially in the same end position so that the crank system during a valve stroke moves through a dead center position.
