Claim 4:
5. The valve according to claim 1, further comprising:
a sleeve housed inside the rotating hollow shutter and defining an annular chamber, said sleeve being provided with at least one first radial opening made on a lateral wall of the rotating hollow shutter, and said sleeve positioned having an end in contact with the bottom of said rotating hollow shutter, and an opposite end of the sleeve facing the inlet opening; and
a floating shutter, slidingly housed inside the sleeve, having a tubular shape, and having an end portion provided with at least one second through radial opening made on the lateral wall of the floating shutter, cooperating and being mated with said first radial opening, said floating shutter defining a first inner chamber and a second inner chamber;
wherein a rotation movement of said second radial opening of the floating shutter with respect to said first radial opening of the sleeve, corresponds to a variation of the passage cross-section proportional to the axial slide of the floating shutter;
wherein said passage cross-section is configured to fluidically connect said annular chamber to the inlet opening of the valve through the first chamber; and
wherein said second inner chamber is fluidically connected to the outlet opening by a passage made through the bottom wall and inner wall.
