<p>The architecture has a normal braking hydraulic circuit (C1) including a pressure control servo valve (BCV) that has a supply port (P) connected to a pressure source (Alim), return port (R) and an utilization port (U) connected to a braking hydraulic actuator (2). A distribution unit is mounted to be mobile so as to connect the utilization port with the supply/return port. A parking hydraulic circuit (C2) has a parking brake valve (PkBV) comprising an outlet port (Ps1) connected selectively to the source/a return circuit (CR) at low pressure. The outlet port is connected to the return port.</p> |
