  • Patent number: 6966614
    Abstract: 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).
