[origin: ES275561U] Regulator of volume of current for technical installations of air, with a section of channel, where a regulating body inclinable is supported around an axis that divides the channel section in half, so that the body of regulation in its current input side has a substantially flat surface and a length equivalent to the height of the channel characterized in that the regulating body (3) in a vertical plane to its axis of inclination (2) has a section (5) of shape semicircular, where the radius of the section is half the height of the channel.
