Fitting

A fitting for a pressurized fluid circuit, comprising:

• a fitting body crossed by a main passage for a pressurized fluid, said main passage extending between a fluid inlet opening and a fluid outlet opening;
• an impeller accommodated in the fitting body and drivable in rotation by the pressurized fluid crossing the fitting body;
• a plurality of magnets supported by the impeller and distributed circumferentially so as to form a magnet ring;
• a plurality of coils housed in the fitting body and distributed circumferentially so as to form a coil ring magnetically coupled to the magnet ring to generate an electric current in presence of a variable magnetic field generated by a rotation of the magnet ring,
• wherein a plurality of nozzles for supplying the impeller is made in the fitting body, the plurality of nozzles extending radially from the main passage, and
• wherein the impeller is in fluidic communication with the fluid outlet opening in such a way that a portion of a fluid flow that enters the nozzles and supplies the impeller is reconveyed towards the fluid outlet opening.
