Patent ID: 8740097

Claim:
A single-control thermostatic cartridge, comprising: a body which delimits internally a chamber for mixing a cold fluid and a hot fluid, a first disk which is stationary relative to the body and which delimits through it at least one cold fluid inlet, at least one cold fluid exhaust, at least one hot fluid inlet and at least one hot fluid exhaust, fluid communication means which can move relative to the first disk and are adapted so as to bring the cold fluid inlet into communication with the cold fluid exhaust of the first disk and as to bring the hot fluid inlet into communication with the hot fluid exhaust of the first disk, a regulator slide which is arranged in the chamber, downstream of the cold fluid and hot fluid exhausts of the first disk, a thermostatic element which is at least partially arranged in the chamber and which is mechanically connected to the regulator slide, and a single control lever for controlling the flow rate and temperature of the mixture of the cold and hot fluids, which is adapted so as to drive the fluid communication means in displacement relative to the first disk and as to displace the thermostatic element inside the chamber, wherein the fluid communication means comprise: a second disk which, relative to the first disk, is both stationary in translational movement radially to a central axis of the body and able to be displaced in rotation about the central axis under the driving action of the control lever via a nut in which an assembly for displacing the thermostatic element is partially accommodated, said assembly being linked to the control lever in rotation about the central axis and provided with extensions mechanically engaging with the second disk in order to drive the latter in rotation, and a third disk which, relative to the second disk, is both linked in rotation about the central axis and able to be displaced in translation radially to the central axis under the driving action of the control lever and which delimits both a cold fluid passage adapted so as to bring the cold fluid inlet of the first disk into communication with the cold fluid exhaust of the first disk via at least one cold fluid inlet and at least one cold fluid exhaust which are delimited through the second disk, and a hot fluid passage adapted so as to bring the hot fluid inlet of the first disk into communication with the hot fluid exhaust of the first disk via at least one hot fluid inlet and at least one hot fluid exhaust which are delimited through the second disk.
