Abstract: The water mixer tap comprises a body defining a dispenser chamber connected to a dispenser conduit. A movable shutter disc is provided in the mixing chamber, and is operable by means of an external lever and acts on two seats, respectively communicating to a hot water inlet conduit and to a cold water inlet conduit. The movable disc defines at least one seat control port which leads into the mixing chamber. The peculiarity of the invention resides in the fact that the control port defines useful flow sections for the water which are variable along planes substantially perpendicular to the plane of contact between the seats and said movable shutter disc.
