According to the present invention, the wall of the downstream end part of the channels of the distributor opposite the fluid supply pipe is preferably at an angle to the axis of the distributor between 90� and 105�.
The downstream end part 9 of the channels 8 is of rectangular cross-section and has two parallel vertical walls 12 and 13, a lower wall 14 inclined outwardly and downwardly and at an angle between 90� and 105� to the axis 1a of the turbine and an upper wall 15 more steeply inclined outwardly than the lower wall 14 so that this downstream end part 9 is outwardly convergent, its peripheral opening 10 being rectangular and the ratio between its height and its width being at least equal to 3. At their inlet 10a the peripheral part of the upstream part 11 of the channels 8 which joins onto the wall 15 of the downstream end part 9 is formed by an annular toroidal spiral 16 which lies in the space between the vertical cylindrical part 5 of the exterior pipe 2 and the interior cylinder 6 at a location that does not violate the laws of flow convergence.
It is seen from FIG. 4 in particular that the channels 8 are successively separated by baffles 17 which form at the periphery of the vertical cylindrical part 5 of the pipe 2 and therefore at the periphery of the distributor 7 cylindrical peripheral surfaces 18 separating the successive outlets 10 of the flow channels 8. The ratio between the circumferential distance e separating two adjacent peripheral outlets 10 of the distributor 7 multiplied by the number n of outlets 10 of the distributor 7 and the perimeter p of said distributor 7 is at least equal to 0.3, in other words: (e�n)/p>0.3.
