Abstract:
1. An architecture for a hydraulic circuit associated with actuators ( 100 ), the architecture comprising a main hydraulic circuit (C) having hydraulic components ( 4 , 5 101 , 6 ) and adapted to convey hydraulic fluid pressurized by at least one pressure generator ( 2 ) associated with a main supply ( 1 ) to the actuators ( 100 ), the architecture further comprising an emergency system, wherein the emergency system comprises an auxiliary supply ( 8 ), which is continuously fed by a return circuit (R) collecting the returns that collects returned fluid from all of the said hydraulic components ( 4 , 5 , 101 , 6 ), the auxiliary supply ( 8 ) itself being connected to the main supply ( 1 ) via a relief valve ( 9 ), said emergency system further comprising an electrically driven pump unit ( 10 ) arranged to take fluid from the auxiliary supply ( 8 ) and inject it said fluid into the main circuit (C) downstream from a general check valve ( 3 ).
