Abstract (en)
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).
Abstract (fr)
L'invention concerne un circuit hydraulique comprenant un réservoir (RSV) de fluide hydraulique, deux pompes (P1, P2), et deux lignes (L1, L2) de distribution de fluide sous pression alimentant respectivement deux récepteurs hydrauliques (R1, R2). Selon l'invention, les lignes de distribution (L1, L2) sont reliées l'une à l'autre par un noeud commun (N12) raccordé à la première pompe (P1) par un premier by-pass commandé (BP1), les lignes (L1, L2) portent des électrovalves d'arrêt respectives (EV1, EV2), et un point intermédiaire (PI2) de la deuxième ligne (L2) est raccordé à la deuxième pompe (P2) à travers un deuxième by-pass commandé (BP2).
