<p>A cartridge intended to be inserted into a body chamber of a mixer valve, which comprises a cage, a fixed plate of hard material, a movable plate of hard material operatively displaceable in the cage and contacting the fixed plate, the plates having mutually cooperating conformations for controlling the flow rate delivered by the valve and the mixing ratio between hot and cold water, and an operator for effecting the displacement of the movable plate in order to execute these controls. The cartridge cage comprises an operatively fixed bottom which is provided at the outside with seals intended to operate between the cartridge fixed bottom and the bottom of the valve body chamber as a consequence of the tightening of the cartridge, and is provided at the inside with couplings complementary to couplings operatively solid with the fixed plate of the cartridge. The fixed plate is mounted within the cartridge cage with a possibility of displacement along a direction perpendicular to its surface contacting the movable plate, and there are provided members with hydraulic effect for applying to the fixed plate a contact pressure against the movable plate.</p> |
