A system is designed for automatic disconnection of fuel supply, in particular of gas supply to a consumer (M) at the moment of stopping the consumer. The supply system comprises fuel cylinders (1) connected with the consumer by a supply line (6) involving one or more cylinder valves (4). The cylinder valves are activated by a pilot line (11). A supply valve (10) is closed before stopping the work of the consumer. Closing of the supply valve (10) causes a drop of the pressure in the pilot line (11) below a level closing of the cylinder valves (4). The consumer (M) is working up to the moment when the pilot line (11) is at a predetermined low pressure level, at the time of which the consumer (M) is shut down leaving the supply line (6) still with unaffected pressure. <IMAGE> |
