Date Mar. 23, 1989.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 of the body of the faucet that has a reduced section and in which one of the supply pipes 2 is connected. The seat 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. In addition, the annular ring has lower teeth 36 which snap fittingly engage with the recesses 29 present on the separate part 25 of the cartridge.</p> |
