Device (1) for automatically regulating the flow rate in a conduit portion (2) crossed by a liquid flow, comprising a regulating member (3), mounted with a facility for limited pivoting or sliding in said portion (2), and an assembly for controlling the position of said member comprising a calibrated actuating component (4) mounted with a facility for displacement in the conduit portion (2) and exposed to the liquid flow (F) by displaying a given exposed surface, a position control mechanism (6, 7") connecting the actuating component (4) and the regulating member (3), and an elastic-action means (5) urging the actuating component (4) toward a position corresponding to a maximum open position of the regulating member (3), counter to the force generated by the pressure of the liquid flow (F) on said component (4). |
