ABSTRACT:
The invention relates to a cartridge thermostatic mixing valve, secured by a ring within a standard tap body, divided into a first upper subassembly made up of the members for transmitting the temperature adjustment (1-10) and a second lower subassembly including the members for transmitting the flow rate adjustment and the valve group which carries out said adjustment (11, 12, 17-24). The first subassembly is removable in an assembled state from the cartridge without acting on the second subassembly which is retained in its position by the ring, so as to remove the member of the thermostatic device for the cleaning of the mixing chamber without requiring to cut off the water upstream from the tap. The cartridge has a simplified structure with a small number of pieces, with the temperature and flow rate controls which are completely independent of each other and consist of a temperature adjustment knob and a flow rate adjustment lever which is rotatable between the knob and the tap body.
