<p>A valve housing has an internal mixing chamber and an elongated passage rising from the mixing chamber. At least two fluid conduits open at the bottom wall of the mixing chamber and communicate with the latter so as to discharge fluid under pressure thereinto. A valve arrangement includes a member of arcuately segmental shape which is provided at its opposite ends with valve members accommodated in the open ends of the conduits and capable of being deflected from the closed position in which they stop fluid flow, to open positions in which they are located farther in the mixing chamber and permit the fluid flow into the same. A valve control element is mounted in the passage and is turnable as well as axially displaceable therein, having a lower end face constructed as a cam face and capable of engaging the valve members in a sense moving them to closed position, or retracting therefrom in a sense permitting the valve members to be displaced by the pressure of fluid in the conduits to positions in which they are spaced at different distances from the openings of the conduits and permit the fluid flow out of the conduits into the mixing chamber at different rates.</p> |
