The stand-by circuit comprises a pressure switch (d) detecting liquefied gas emptiness in the gas bottle (g) and actuates transmission of control signal. There is stand-by container (r) accumulating liquefied gas via bypass (b) and pressure dependent valve (v). According to the empty state, the stand-by container powers the drive (a). There are also a signal emitter, safety elements, and detectors of stand-by running period. Pref. the valve is a pressure regulator.
