Abstract
This flow regulation device comprises a housing (200) having an inlet port (202) and an outlet port (204), and a fluid flow conduit (206) between them, a valve body (208) mounted in the housing (200), and a first (210) and a second (212) orifices allowing fluid flow in the conduit (206). The valve body (208) is movable between an open position, in which the first and second orifices (210, 212) are open, and a closed position, in which only one (210) of the first and second orifices (210, 212) is open. The flow regulation device (20) comprises a resilient element (214) urging the valve body (208) towards its open position, and the valve body (208) passes from its open to its closed position under action of fluid pressure (P) entering in the inlet port (202).
