| 摘要 |
The invention relates to an architecture for a hydraulic circuit associated with actuators ( 100 ), such as actuators for airplane brakes, 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 includes an emergency system comprising an auxiliary supply ( 8 ) permanently fed by a return circuit (R) collecting the returns from all of the hydraulic components ( 4, 5,101, 6 ), the auxiliary supply ( 8 ) being connected to the main supply ( 1 ) via a relief valve ( 9 ). The emergency system further comprising an electrically driven pump unit ( 10 ) arranged to take fluid from the auxiliary supply ( 8 ) and to inject it into the main circuit (C) downstream from a general check valve ( 3 ).
