<p>Mixing valve, in particular for heating and hot water plant, incorporated in the casing (7) of a circulation pump (8) in such a manner that the mixer regulator (11), in the form of a vane-type wheel, and the pump rotor are aligned in the same axis, said regulator being thus movable by the drive system provided for the pump rotor by means of an actuatable link or coupling elements which can be engaged or disengaged. The regulator is designed to enable, even in the "closed" direction, irrespective of its position or of that of its vanes, a water exchange of the order of 10% of the water flow rate, ie much less than the total through-flow capacity, the return water of the heating circuit (6) being thus mixed and therefore reheated before its return into the boiler (1).</p> |
