Abstract (en)

[origin: WO2009130724A1] A hydraulic device (1) for feeding and controlling a fluid stream towards users, comprising a delivery branch (2) of the stream towards users, a return branch (3) of the stream from users, a measuring instru¬ ment (4) of the instantaneous flow rate of the stream in the return branch (3), a first hydraulic path (5) put- ting the delivery branch (2) in fluid communication with the return branch (3), a shut-off valve (6) placed on the delivery branch (2), which can be operated between a first operating configuration in which it allows the stream to get through the delivery branch (2) so as to reach the users and a second operating configu¬ ration in which it diverts the stream from the delivery branch (2) towards the return branch (3) without get¬ ting through users, a first balancing valve (10) placed on the delivery branch (2), and a second balancing valve (11) placed on the first hydraulic path (5), wherein the first hydraulic path (5) fits into the return branch (3) upstream, with respect to the flowing direction (R) of the stream in the return branch (3), from the measuring instrument (4).
