Title (EN) FUEL CIRCUIT OF AN AERONAUTICAL TURBINE ENGINE HAVING A FUEL PRESSURE REGULATING VALVE
(FR) CIRCUIT DE CARBURANT DE TURBOMACHINE AÉRONAUTIQUE A VANNE DE RÉGULATION DE PRESSION DE CARBURANT.
Abstract: front page image
(EN)The invention relates to a fuel circuit (10) of an aeronautical turbine engine, comprising a main fuel line (12) intended to supply fuel to a combustion chamber (24) of the turbine engine and including a positive-displacement pump (20), an auxiliary fuel line (30) connected to the main fuel line at a joint (32) located downstream of the pump and intended to supply fuel to hydraulic actuators (34) for controlling variable geometry devices of the turbine engine, the auxiliary fuel line including electro-hydraulic servo valves (36) upstream of each cylinder, and a fuel pressure regulating valve (40) arranged on the main fuel line downstream of the pump.
(FR)L'invention concerne un circuit de carburant (10) de turbomachine aéronautique, comportant une ligne principale de carburant (12) destinée à alimenter en carburant une chambre de combustion (24) de la turbomachine et comprenant une pompe volumétrique (20), une ligne auxiliaire de carburant (30) reliée à la ligne principale de carburant au niveau d'une jonction (32) située en aval de la pompe et destinée à alimenter en carburant des actionneurs hydrauliques (34) pour la commande d'équipements à géométrie variable de la turbomachine, la ligne auxiliaire de carburant comprenant des servovalves électrohydrauliques (36) en amont de chaque vérin, et une vanne de régulation de pression de carburant (40) disposée sur la ligne principale de carburant en aval de la pompe.
