Abstract

Clapet de surpression (40) pour un circuit de carburant (10) d’une turbomachine d’aéronef, ce clapet comportant : - un premier orifice (40a) d’entrée de carburant, - un orifice (40b) de sortie de carburant, - un tiroir (48) monté mobile entre deux positions de fermeture et d’ouverture du clapet, - et un ressort de compression (52) pour solliciter le tiroir (48) dans sa position de fermeture, caractérisé en ce que ledit ressort (52) est taré de sorte qu’il se comprime automatiquement et autorise le déplacement du tiroir (48) de la première à la seconde position lorsqu’une différence de pression au niveau des orifices est supérieure ou égale à un seuil prédéterminé, et en ce qu’il comprend en outre : - un second orifice (40c) d’entrée de carburant uniquement lorsque le tiroir (48) est dans sa position d’ouverture afin que ce carburant maintienne le tiroir dans cette position. Figure pour l'abrégé : Figure 3Pressure relief valve (40) for a fuel circuit (10) of an aircraft turbine engine, this valve comprising: - a first fuel inlet orifice (40a), - a fuel outlet orifice (40b), - a spool (48) mounted to move between two positions of closing and opening of the valve, - and a compression spring (52) for urging the spool (48) into its closed position, characterized in that the said spring (52 ) is calibrated so that it automatically compresses and allows the movement of the slide (48) from the first to the second position when a pressure difference at the level of the orifices is greater than or equal to a predetermined threshold, and in that it further comprises: - a second fuel inlet port (40c) only when the slider (48) is in its open position so that this fuel maintains the slider in this position.
