<p>The invention relates to a water flow control unit in mixing valves for hot and cold water comprising two overlapping ceramic disk (11,12) one of which is fixed and the other movable. The fixed disk (11) has two inlet holes (15,16) which are substantially of uniform width and are symmetrically cut, with respect to a water dividing partition (19), into one half of the same disk. The fixed disk (11) also has an elliptic shaped outlet hole where one part is placed between the two inlet holes or openings (15,16) and the other part extends into the other half of the fixed disk. The movable disk (12) has a mixing chamber defined by a circular part (18a) off-centre from the middle of the same disk and a communicating polygonal part (18b).</p> |
