The regulator has pressure probes (2, 3) with openings (4) placed inside the channel. The first pressure probe (2) is placed on a leading side of the blade (1) in its back part, the second pressure probe (3) is placed on the opposite side of the blade (1) in its front part. The pressure probes (2, 3) are connected with an element (6) for the assessment of the differences in pressures by means of the hoses; the element (6) is placed on the outer side of the channel. The openings (4) of both pressure probes (2, 3) are oriented in parallel with the surface of the blade (1) and they head towards each other, towards the axis (7) of the blade (1) - basically to the middle of the blade (1). The placement of the openings (4) of the first and second pressure probe (2, 3) is delimited by first and second rectangle (8, 9) of the effective position, which delimits the distance of the opening (4) from the edge of the blade (1) and also from the plane of the blade (1), and which are present in the longitudinal axial plane of the channel which is perpendicular to the axis of the blade's (1) rotation.
