<p>The improvements consist in the incorporation of a teflon runner 5 on whose periphery there is a toothing in the form of saw teeth forming compression angles 18 which face tangential conduits 17 for the entry of pressurized water, causing it to rotate. The water housed inside the cavity 4 which is the housing for the runner 5 is removed via the annular cavity 19, impelled by the angle of expulsion 20 into the peripheral toothing of the runner and behind the compression angle 18 in order optionally to be recycled for re-use.</p> |
