Abstract

Dispositif de régulation du débit de carburant fourni à la chambre de combustion d'une turbine à gaz. Une pompe volumétrique 1, entraînée à une vitesse de rotation proportionnelle à celle de la turbomachine, alimente en carburant la chambre de combustion à travers deux étranglements montés en cascade 4, 5, l'étranglement aval 5 ayant une section de passage pilotable; une soupape régulatrice 7 sensible à la chute de pression pa -pc à la traversée des deux étranglements 4, 5 règle un débit de fuite de carburant prélevé entre ceux-ci, pour maintenir cette chute de pression à une valeur constante. Application à la régulation de secours d'un turboréacteur d'aviation.
