Abstract:
1. A cartridge for a mixer faucet, comprising two ceramic disks for regulating a temperature and flow of a mixture (M) of two fluids (F,C) entering the cartridge at different respective temperatures, and thermostatic means suitable for, when the temperature of the mixture is greater than a first predetermined threshold value (T d ), automatically regulating flow, upstream of the disks, of the hottest entering fluid (C), which thermostatic means includes: a valve element for controlling flow of the hottest fluid (C) through a passageway defined by the cartridge upstream of the disks, and a thermostatic element including both a heat sensitive portion placed, at least partly, in the flow path of the mixture (M) in the cartridge and downstream of the two disks, and a movable portion that moves in translation relative to the heat sensitive portion and which moves the valve element to regulate flow through the passageway of the hottest fluid (C) to thereby regulate the temperature of the mixture (M), and a seal for sealing the valve element relative to the passageway of the hottest fluid when the temperature of the mixture (M) is greater than a second predetermined threshold value (T
