  • Patent number: 11028930
    Abstract: A single control mixer valve structure for taps and fittings comprising a fixed disk provided with an outlet port and two ports, respectively, one for the hot water and the other for the cold water that come from two inlet openings, formed in a base, mounted in which is the fixed disk on which a mobile disk mounted in a mobile-disk holder is able to slide; the mobile-disk holder and the mobile disk define a mixing opening, which is adapted to connect the inlet openings with an outlet opening, formed in the base, in a position corresponding to the outlet hole on the fixed disk, from which the mixed water flows out; sliding of the mobile disk on the fixed disk causes partial opening or complete closing of one or both of the ports of the fixed disk, thus adjusting the amount of hot water and cold water that passes from the inlet openings to the outlet opening for the mixed water; the mixer valve structure is characterised in that the mobile-disk holder has, on the side facing the fixed disk, a body that is close
