The device comprises: a solenoid valve of the bistable type controlled by means of an operating winding; a control circuit coupled for operation to a power supply source and capable of supplying to the operating winding of the solenoid valve a first and a second current pulse, for opening and closing the solenoid valve respectively; and a detecting and operating device associated with the said solenoid valve, capable of detecting a predetermined dangerous operating condition thereof, and of causing, in such a case, the automatic reclosing of the valve for cutting off the flow of the fluid.

The device comprises a tubular stator intended to be fixed in a pipe, so as to be traversed, in use, by said stream of fluid, and in which there is axially mounted a rotor which has a central hub from which extends a plurality of blades and which is capable of being operated in rotation by said stream, like a turbine, at a velocity variable according to the flow rate, and at least one permanent magnet integral with the rotor, disposed eccentrically with respect to the axis of rotation of said rotor. Fixed to the hub of the rotor is a shaped support bush mounted rotatable about a fixed pin or shaft which extends, projecting in the opposite direction to the operational direction of flow of the stream, from a central support integral with the axial outlet portion of the stator. The magnet is held in a housing defined between the support bush and the rotor.
