<p>The invention relates to an arrangement with a control valve for the regeneration of a water treatment system in which the brine injector (62-64) provides a constant flow of brine independently of the water supply pressure. The invention comprises means of controlling flow rate which are sensitive to pressure in the injector housing, and which can be in the form of a valve connected to a diaphragm (56) arranged between the water entry (38) and the injector (62). The valve (42), normally stressed towards its open position, is pushed back towards its closed position by the pressure of the entering water acting on the diaphragm, and this regulates the flow of water which is sent inside at a predetermined constant rate. <IMAGE></p> |
