Abstract
Aircraft hydraulic parking architecture, including a brake with a wheel braking hydraulic actuator, a pressure source (Alim) of high-pressure fluid, a normal braking hydraulic circuit (C1) including at least pressure control servo valve with a supply port (P) connected to the pressure source (Alim), a return port (R), a utilization port (U) connected to the actuator, the brake architecture further including a parking hydraulic circuit (C2) including a parking brake valve (PkBV) having an outlet port (Ps1) selectively connected either to the pressure source (Alim) or a low-pressure return circuit (CR).The outlet port (Ps1) of the parking brake valve (PkBV) is connected to the return port (R) of the pressure control servo valve.
