Abstract:
Cartridge for a reverse-flow mixer tap comprising a body (1; 1A, 1B) in which there terminate a first fluid inlet duct (F) for conveying fluid at a first temperature into the body, a second fluid inlet duct (C) for conveying fluid at a second temperature higher than the first temperature into the body, and a fluid discharge duct (M) for discharging fluid at a desired temperature in the range extending from the first temperature to the second temperature from the body, the cartridge being characterized in that it comprises a bypass (B) connecting the first inlet duct (F) to the discharge duct (M) and is equipped with a device (7, 8; 7, 8, 9) for shutting off the bypass comprising a thermostatic element (7) equipped with a shut-off element (74; 9) designed to shut off the bypass (B) as long as the temperature of the discharged fluid remains below or equal to a predetermined set temperature, and to uncover the bypass when the temperature of the discharged fluid exceeds this temperature, so as then to cause fluid to flow from the first inlet duct (F) to the discharge duct (M) through the bypass (B).
