Abstract
A safety valve () has a first valve, and a second valve, a magnetic armature () moved by voltage applied to a coil (). Movement of the armature () acts against a spring force of the first valve spring () and loosens the first valve body () from the first valve seat (). The movement of the armature () subsequently acts against a spring force of the second valve spring () and loosens the second valve body () from the second valve seat (). This frees a valve opening for a flowthrough of the gas flow. The flowthrough amount of the gas flow through the valve opening can be continuously controlled as a function of the voltage applied to the coil () between a closed position and a fully open position even in partially open positions.
