- the arrangements of the drawer 20, such as the seal 21, making it possible to seal off one with respect to the other the hot water 14 and cold water 15 inlets outside the drawer are not limiting.
- the cartridge 1 To drive the slide 20 in translation along the central axis XX, the cartridge 1 comprises a thermostatic element 30 which includes a thermosensitive body 31 and a piston 32, which, in the assembled state of the components of the cartridge, are substantially centered on the central axis XX.
- the thermostatic element 30 is designed so that its thermosensitive body 31 and its piston 32 move with respect to one another along the central axis XX, this relative displacement being controlled by a temperature variation applied to the thermosensitive body 31
- the thermosensitive body 31 contains, for example, a thermosensitive material which, during its expansion, causes the deployment of the piston 32 relative to the thermosensitive body 31 and which, during its contraction, allows the retraction of the piston relative to it. with thermosensitive body.
- thermo-actuation can be envisaged for the thermostatic element 30.
- this thermosensitive body 31 is designed to be in contact with the mixed water, being at least partially placed in the chamber 11 and / or in the mixed water outlet 16.
- thermosensitive body 31 is integrally connected to the drawer 20, for example by screwing, it being emphasized that the embodiment of this joining between the drawer 20 and the thermosensitive body 31 is not limiting and above all that this joining extends as being a kinematic connection from one to the other for the purpose of moving the slide in order to close, in opposite respective proportions, the passages of hot water P1 and cold water P2.

- the piston 32 deploys axially with respect to the thermosensitive body 31, which causes the downward translation of the thermosensitive body 31 and therefore of the drawer 20: the proportion of hot water circulating in the hot water passage P1 decreases while, conversely, the proportion of cold water circulating in the passage of cold water P2 increases, resulting in a drop in the temperature of the mixed water.
- a compression spring 33 is provided to return the thermostatic body 31 and the piston 32 towards one another when the latter retracts, for example during a contraction of the heat-expandable material contained in the heat-sensitive body 31.
- this return spring 33 is interposed axially between the casing 10 and the spool 20.
- the corrections of the temperature of the mixed water result in a regulatory equilibrium for this temperature of the mixed water, and this at a thermostatic regulation temperature which depends on the position, imposed by the mechanism 40, of the piston 32 along the central axis XX.
- the mechanism 40 makes it possible to adjust the value of the thermostatic regulation temperature and thus to control the temperature of the mixed water, by acting on the axial position of the piston 32.

It will be recalled that the embodiment of this mechanism 40 is not limiting the invention: other embodiments are known in the art, for example in FR 2 921 709, FR 2 774 740 and FR 2 870 611. Moreover, by way of a variant not shown, if it is dispensed with being able to adjust the value of the temperature at which the spool 20 regulates the mixture of hot water and cold water, the mechanism 40 can be omitted from the cartridge. thermostatic 1, the piston 32 then being fixedly connected to the casing 10.

- the chamber 11 is adapted to the non-circular profile of the drawer 20, in the sense that, in cross section to the central axis XX, the chamber 11 has, at the axial level of the drawer 20, a non-circular section, which is complementary to the profile of the drawer.
- the chamber 11, more precisely the side wall 17 of the latter is cylindrical having an elliptical base, which is centered on the central axis XX, whose major axis s' extends along the first geometric axis Z1 and whose minor axis extends along the geometric axis Z2. The same is true for joint 21.
- the elliptical shape illustrated in the figures is only an example of a non-circular geometry for the profile of the drawer 20 and, consequently, for the complementary section of the chamber 11.
- the profile of the drawer 20 is different from a circle, in the sense that the profile of the drawer 20 differs from the profile of known drawers, which is typically substantially circular, that is to say circular at manufacturing tolerances close.
- the non-circularity of the profile of the drawer 20 allows the thermostatic cartridge 1 to adapt to various geometries of the implantation environment.
- the profile of the drawer 20 is then advantageously provided truncated in this portion. Consequently, the precise geometry of the profile of the drawer 20 is not limiting for the invention as long as this geometry is non-circular as indicated above.
- the profile of the drawer 20 can advantageously be asymmetrical or symmetrical. As examples of an asymmetric profile, there may be cited a truncated circular profile, a multilobed profile, etc.
- an oval profile can be cited, a profile including one or more pairs of opposite parallel rectilinear edges, such as a rectangular or square profile with rounded corners, etc.
- the non-circular profile of the drawer 20 does not limit the flow of mixed water from the thermostatic cartridge 1, in the sense that, compared to a drawer having a given circular profile and therefore a corresponding perimeter, the non-circular profile of the drawer 20 is advantageously dimensioned to have the same perimeter value and therefore the same flow section values for the hot water P1 and cold water P2 passages.
- the profile of the slide 20 has a geometric shape which is more extensive along the first geometric axis Z1 than along the second geometric axis Z2.
- This arrangement is implemented in the exemplary embodiment considered in the figures, as detailed above in connection with the dimensions d1 and d2 of the elliptical shape.
- this arrangement is implemented with other geometries for the profile of the drawer 20, in particular an oval geometry or else a geometry including two parallel rectilinear edges, such as an oblong geometry or a rectangular geometry with rounded corners. .
- this arrangement advantageously allows the thermostatic cartridge 1 to be implantable in an environment of reduced width, that is to say an environment having a smaller dimension than its other two dimensions.
- the envelope 10 can then be provided “flattened” along the second geometric axis Z2, in the sense that the envelope 10 then has a total dimension, measured according to the second geometric axis Z2 and denoted D in Figures 3 and 4, which is smaller than all the other total dimensions of the envelope.
- the hot water inlet 14, the cold water inlet 15 and the discharge d 'mixed water 16 extend from the chamber 11 in the same geometric plane containing the central axis XX and the first geometric axis Z1, this geometric plane being denoted p in Figure 1 and corresponding to the section plane of Figure 2.
- this insert is referenced 50 and consists of a fork which is arranged transversely to the central axis XX.
- the embodiment of this insert 50 is not limiting.
- hot and cold water inlets can be provided as in Figures 6 and 7 which illustrate a variant in which the casing, the hot water inlet and the cold water inlet of the thermostatic cartridge are respectively referenced 10 ', 14' and 15 '.
- These hot water 14 'and cold water 15' inlets extend from the chamber 11 parallel to the axis XX and open, opposite this chamber, on the side of the casing 10 'opposite to that of the mechanism 40.
- the drawer 20 and the thermostatic element 30, as well as, where appropriate, the mechanism 40 are assembled to each other in the form of a thermostatic cartridge capable of being inserted in one piece in a valve body, such as the thermostatic cartridge 1 envisaged hitherto, the drawer 20 and the thermostatic element 30, as well as, where appropriate, the mechanism 40, can be installed directly in a valve body, the latter then forming an envelope functionally similar to the envelope 10 or 10 '.
