ABSTRACT:
The cartridge comprises two ceramic disks (20, 24) for regulating the temperature and flow of a mixture (M) of two entering fluids. In order to ensure that the temperature of the mixture remains lower than a predetermined value, the cartridge comprises thermostatic means (16) designed for, in the event of a high-temperature mixture, automatically shutting off, upstream from these disks, the circulation of the entering fluid (C) of the highest temperature. In order to limit their size, these means comprise: a closure element (34), which serves to close a passage (56) of the fluid (C) having the highest temperature and which is delimited by the cartridge, and; a thermostatic element (36) including a thermosensitive part (38) placed along the flow path of the mixture and a mobile part (40) connected in translation to the closure element, said closure element being mounted in a manner that enables it to slide in an area (42A) of the passage of the fluid of the highest temperature, with the interposition of a packing seal (58), which is joined to this area and which, when the temperature of the mixture is greater than the predetermined value, is capable of forming a sliding tight contact with the closure element.
