HYDRAULIC LOAD-SENSING FLOW-SHARING SYSTEM
A hydraulic directional load-sensing flow-sharing system (9), of the type comprising two independent circuits at the sides of an intermediate summation element (3). The two circuits are configured for connecting to a low pressure line (T) and respective load-sensing (LS) delivering apparatus (PA) and (PB) via respective high pressure lines (P1) and (P2) and load-sensing signal lines (LS1) and (LS2); each line (LS1) and (LS2) connectable to a respective bleed valve (b1) and (b2). The two circuits are connectable to respective utilities via the connections (A1, B1, A2, B2, A3, A4, B3, B4) placed on respective elements (E1, E2, E3, E4) of said modular hydraulic system (9), of which (E2) and (E3) are served by said apparatus (PA) and (PB), respectively. The intermediate summation element (3) can be controlled electrically to keep (P1) and (P2), channels (ST1) and (ST2) coming from said elements (E1, E2) and signals (LS1) and (LS2) separated, or keep them combined. In a first position (I), element (3) keeps the circuits and thereby the high pressure lines (P1) and (P2), elements (E2, E3) downstream of the relative compensators and upstream of the return to the relative spools (ST1 and ST2) separated and independent, it also keeps lines (LS1) and (LS2) separated; in a second position (II), it combines the two circuits into one, combining the high pressure lines (P1) and (P2), and elements (E2, E3); channels (LS1) and (LS2), connecting them to only one of the two bleeds; in a third position (III), it only connects the high pressure lines (P1) and (P2), keeping lines (LS1) and (LS2) separated; also keeping (ST1) and (ST2) of elements (E2, E3) separated.
