Zusammenfassung:The device has a pressurization and cut-off valve (20) with a piston that is sensible to the fuel pressurization for closing a supply conduit (22) as long as the pressurization is lower than a preset threshold. The valve has an opening, an annular groove and radial openings to apply fuel counterpressure (PH), creating fuel pressurization threshold, to the piston from idling speed of a turbomachine, where the pressurization threshold is higher than the preset threshold and is higher than minimum control value of variable geometry equipments (24) e.g. variable setting blade, of the turbomachine.
