Abstract (en)

[origin: EP2302221A1] The circuit has pressurized fluid distribution lines (L1, L2) connected to each other by a common node (N12) that is connected to a pump (P1) by a controlled by-pass (BP1). An intermediate point (PI2) of one of the lines is connected to another pump (P2) through another controlled by-pass (BP2). The by-passes are placed in an active position in which fluid traversing the by-passes respectively feed two receivers (R1, R2), and in a recirculation position in which the fluid traversing the by-passes returns to a hydraulic fluid reservoir (RSV).
