<p>A mixing faucet for hot and cold water including a cartridge (40) which contains a fixed valve plate (32) and a movable valve plate (23), both constructed of hard ceramic material, and both constructed to control the proportion of mixing and the flow that comes out of the faucet. In this faucet, the part (25) of the cartridge that has the seat for the fixed valve plate (32) constitutes an element which is separate from the cover (16) of the cartridge. It is mounted in the cover (16) for sealed axial movement and is arranged so that sealed flow can occur from a part of the cavity (5) of the body of the faucet that has a reduced section (6) and in which one of the supply pipes (2) is connected. The part (25) for the valve plate has some projections (30) which can interact in the passage apertures (32a) to laterally affix the plate (32). The cartridge has an annular ring (34) which has some upper teeth (35) that engage with corresponding recesses (33) present peripherally on the work face of the fixed valve plate (32). In addition, the annular ring (34) has lower teeth (36) which snap fittingly engage with the recesses (29) present on the separate part (25) of the cartridge.</p> |
