<p>The invention concerns a device (50) for regulating a flow of fluid into a hydrocarbon tank well, comprising a fluid inlet (62), a fluid outlet (64), a stator (52), a rotor (54) mounted so as to rotate relative to the stator along an axis extending from the fluid inlet towards the fluid outlet, the stator and the rotor forming cavities which progress from the fluid inlet to the fluid outlet when the rotor is made to rotate relative to the stator, and a system (56) for regulating the rotational speed of the rotor relative to the stator. The device enables the flow of fluid in a hydrocarbon tank well to be regulated in improved manner.</p> |
