<p>The diverter (1) has a tubular body (2) with two supplying orifices (3, 4) connected to distinct gas sources e.g. gas bottles, and an outlet orifice (5) is connected to an utilization circuit. The supplying orifices emerge from both side of a disk-shaped slider housed in a switching chamber (20), and are provided with valves (6, 7) having springs (10, 11) supporting against the slider. A magnetic control unit (16) e.g. electromagnet, is placed outside of the chamber, and develops magnetic field permitting displacement and maintenance of the slider in a given position.</p> |
