Abstract
A pair of ceramic disks for mixer faucets includes a fixed disk and a smaller mobile disk adapted to slide on the fixed disk within given limits. The fixed disk has on one side a bearing surface adapted to lie against the mobile disk and has two feed openings and one outlet opening through it. The bearing surface of the fixed disk has a closed main rim around the three openings and at least one depression in the surface through only part of the thickness of the fixed disk. In any position of the mobile disk relative to the fixed disk, the bearing surface of the mobile disk bears on the rim all around the depression. The bearing surface further includes an inner rim which in the closed position of the mobile disk isolates the outlet opening from the feed openings.
