Abstract (en)
[origin: WO9001614A1] An electromagnetically actuated control device for gas change-over valves which opens and closes the valves by causing an armature plate (18) to move between facing electromagnets (14, 16) comprises a subdivision between the armature plate (18) and the valve stem (28). A spring system (38) on one side of the armature plate (18) thrusts the latter into the open position of the gas change-over valve. On the other side is a double spring system one part (40) of which thrusts the armature plate into the closed position of the gas change-over valve, while the second part (42) of this double system acts on the valve stem (28) in the closed position of the gas change-over valve.
