    Assembly for manufacturing a cold and hot fluid control cartridge to be mixed
    The present invention relates to a manufacturing assembly of a cold and hot fluid control cartridge to be mixed.
    In the sanitary field, a cartridge is a device for regulating hot and cold fluids to mix, including hot and cold water.
    The cartridge is qualified as thermostatic when it incorporates a thermostatic actuator, in particular a thermostatic element, which comprises a first part, normally fixed relative to a hollow base of the cartridge, and a second part, movable along an axis of the base relative to the first part under the effect of the temperature applied to the actuator, for example by the action of the expansion of a thermally expandable material contained within the thermostatic element. The second part of the thermostatic actuator is provided integral with an axially displaceable slide inside the base of the cartridge, so as to inversely vary the passage sections of the passages of the hot fluids. and cold in the base, in order to mix these two fluids in variable proportions to obtain, downstream of the spool, a fluid, said mixed fluid, mixture or mixed fluid, flowing along a thermosensitive region of the thermostatic actuator and coming out of the base. By modifying the position of the first part of the thermostatic actuator relative to the base, by means of an ad hoc setpoint mechanism, the target temperature is varied around which the temperature of the mixture is thus regulated by the drawer.
    Furthermore, to vary the flow rate of cold fluid and the hot fluid flow rate sent to the drawer via the base, the cartridge incorporates an adjusting member, such as a set of ceramic discs, which is mounted so at least partially movable in a housing fixed to the base.
    Such a thermostatic cartridge is divided into several types depending on how the flow rate and the temperature of the mixture coming out of the cartridge are controlled. Thus, the cartridge is said to be single-control when the flow rate and the temperature of the mixture are controlled jointly, by means of permanently actuating the above-mentioned adjustment member with one another, making it possible to adjust the flow rates of cold fluid and hot fluid sent to the drawer via the base, and the aforementioned setpoint mechanism, to change the position of the thermostatic actuator. When the flow of the mixture and the temperature of the mixture are controlled separately from one another, by means of independent actuations of the above-mentioned adjustment member and setpoint mechanism, the cartridge is said to be dual-controlled. The cartridge can also be called sequential when the flow rate and the temperature of the mixture are controlled successively, by first actuating the adjusting member without actuating the setpoint mechanism, and then the conjoint actuation of the adjustment element. and the deposit mechanism.
    It is understood that each type of thermostatic cartridge meets specific specifications and is subject to specific arrangements, in particular to optimize the control performance and the maximum allowable flow. At the level of the manufacture of these cartridges, this induces specificities of design, assembly and selection of the constituents of each type of cartridge. In other words, each type of cartridge requires technical and financial investments of its own, which, for a given market player, involves substantial costs to offer several types of cartridge simultaneously.
    The object of the present invention is to seek to have at lower investments a range of several types of thermostatic cartridge. For this purpose, the subject of the invention is an assembly for manufacturing a cartridge for regulating cold and hot fluids to be mixed. This set includes a basic module including: - a base, which defines a main axis and which encloses a chamber for mixing cold and hot fluids, this chamber being connected to the outside of the base by both the first and second inputs, respectively for the cold fluid and for the hot fluid, and an outlet for mixing cold and hot fluids, - a slide which is movable parallel to the main axis inside the chamber so as to vary in opposite manner the respective flow sections of a first passage fed by the first input and a second passage fed by the second input and a thermostatic actuator which is at least partly arranged in the chamber and which, depending on the temperature of the mixture, moves the drawer inside the chamber to a control position corresponding to a set temperature which is defined by the axial position of a dedicated part of the thermostatic actuator.
    This set also comprises at least two specific modules among a single-control module, a sequential module and a dual control module, each of these specific single-control, specific and dual-control modules including: a housing which is adapted to be fixed to the base of the module; base, and - a setting member which is mounted in the housing at least partially movable so that, when the housing is attached to the base, vary the flow rate of the cold fluid, sent to the first inlet, and the flow of hot fluid, sent to the second inlet.
    The single-control module further includes a control mechanism adapted to, when its housing is fixed to the base, jointly control the flow and the temperature of the mixture by providing for driving its adjustment member and the dedicated part of the thermostatic actuator. constantly with each other. The sequential module further includes a control mechanism adapted to, when its housing is fixed to the base, successively control the flow and the temperature of the mixture by first providing for driving its adjustment member without causing the dedicated part of the thermostatic actuator, then drive its regulator and the dedicated part of the thermostatic actuator with each other. And the dual control module further includes a control mechanism adapted to, when its housing is fixed to the base, separately control the flow and temperature of the mixture by providing for driving its adjustment member and the dedicated portion of the actuator thermostatic independently of one another. In addition, in this set, each of the basic, single-control, sequential and dual-control modules is preassembled independently of the other modules, and the base module and said at least two specific modules are designed so that the base module can be assembled. indifferently to any of said at least two specific modules.
    One of the ideas underlying the invention is to rely on a modular design of the thermostatic cartridges to manufacture. Thus, the basic module belonging to the manufacturing unit according to the invention is designed to be shared by at least two or even three of the various types of cartridge envisaged, which are the single-control type, the sequential type and the two-control type. This basic module integrates the thermostatic regulation of the cartridge and thus forms a preassembled base to which it is possible to assemble indifferently any of the preassembled specific modules belonging to the assembly of manufacture according to the invention, in order to manufacture a functional thermostatic cartridge. Each of the specific modules integrates the adjustment of the flow rates of cold fluid and hot fluid sent to the base of the base module, the embodiment of the member providing this adjustment is not limited to the invention and can elsewhere vary from one specific module to another. The specific modules are distinguished from each other by the way in which the flow and the temperature of the mixture are controlled which will come out of the basic module in the assembled state of the manufactured cartridge, thus distinguishing the single-control, sequential and two-component modules as defined above. The invention is thus similar to a concept of "assembly platform" through which one can manufacture different types of cartridge, which all have a part of their cartridge, which is identical between the different types and which corresponds to the module basic, but which are differentiated by a specific part corresponding to each of the specific modules single control, sequential and two-way control. As the basic module integrates the thermostatic regulation function, which is the most complicated to design and which is the most likely to evolve, the technical and financial investments that are necessary for the provision of two or even three modules Specifically, while ensuring assembly compatibility of the latter with the basic module, are substantially less than the investments that would be necessary to put into production the same types of cartridges designed dissociated from each other.
    According to additional advantageous features of the manufacturing assembly according to the invention, taken individually or in any technically permissible combination: the assembly comprises both the single-control module, the sequential module and the two-control module, and the modules basic, single-control, sequential and dual-control are designed so that the base module can be assembled regardless of the single-control module, the specific module or the dual-control module; the thermostatic actuator comprises, or even consists of, a thermostatic element comprising: a piston which forms said dedicated part of the thermostatic actuator, and a body, which contains a thermally expandable material, which is at least partially arranged in the chamber and which is connected to the spool so as to move it parallel to the main axis, the piston and the body being movable relative to each other parallel to the main axis under the effect of the expansion of the thermally expandable material ; the thermostatic actuator comprises, or even consists of, a shape memory element as a function of temperature, in particular a shape memory spring; the control mechanism of each of the single-control, sequential and dual-control modules includes: a screw and a nut, which are screwed to one another and which, when the housing of the corresponding specific module is fixed to the base of the basic module, are substantially centered on the main axis, one of this screw and nut being rotatably connected about the axis to the housing while the other is rotatable about this axis relative to the housing, and a rod, which, when the housing of the corresponding specific module is fixed to the base, is substantially centered on the main axis and connects the screw to the dedicated part of the thermostatic actuator so as to axially move this dedicated part by drive by the screw; - The screw and the rod are identical between the single-control, sequential and two-component modules; the rod has a first axial end, which is pressed axially against the dedicated part of the thermostatic actuator, and a second axial end, which is opposite to the first axial end and which bears axially against the screw with interposition of an overtravel spring; the control mechanism of the single-control module includes a single knob for controlling the flow rate and the temperature of the mixture, which is mounted relative to the housing of the single-control module in a manner that is mobile both in rotation around the main axis and in tilting around a secondary axis, perpendicular to the main axis, when the housing is attached to the base module base, - the control mechanism of the sequential module includes a single control ring of the flow and temperature of the mixture which is movably mounted relative to the sequential module housing exclusively in rotation about the main axis, and - the control mechanism of the dual control module includes a mixture flow control ring and a temperature control ring. of the mixture, which are distinct from each other and which are mounted relative to the housing of the bi-control module in a mobile manner exclusively in rotation r of the main axis. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings, in which: FIG. 1 is a perspective view of a production assembly in accordance with FIG. the invention; - Figures 2 and 3 are longitudinal sections, in respective orthogonal planes to one another, a base module belonging to the assembly of Figure 1; - Figures 4 and 5 are views similar to Figures 2 and 3 and illustrate the assembly of the base module with a specific module of the assembly of Figure 1; and FIGS. 6 and 7 and FIGS. 8 and 9 are views respectively similar to FIGS. 4 and 5 and respectively illustrate the assembly of the base module with two other specific modules of the assembly of FIG. 1.
    In Figure 1 is shown an assembly for manufacturing three different thermostatic cartridges, namely a single-control cartridge 1, shown in Figures 4 and 5, a sequential cartridge 2, shown in Figures 6 and 7, and a dual control cartridge 3 shown in FIGS. 8 and 9. Each of these cartridges 1, 2 and 3 is adapted to equip a mixing valve of hot and cold water, not shown as such in the figures, or, more generally, to equip a sanitary installation. The manufacturing assembly of FIG. 1 comprises a base module 100 and three specific modules, namely a single-control module 200, a sequential module 300 and a dual-control module 400. The basic module 100, which is shown alone in the figures 2 and 3, is arranged along a main axis XX. The modules 100 and 200 are designed to be assembled together, centrally on the axis XX, and thus to form the single-control cartridge 1. The modules 100 and 300 are designed to be assembled together. the other, centered on the axis XX, and thus to form the sequential cartridge 2. The modules 100 and 400 are designed to be assembled to each other, centrally on the axis XX, and to thereby form the dual control cartridge 3.
    For convenience, the following description is oriented relative to the axis XX, considering that the terms "upper", "top" and the like correspond to an axial direction facing the upper part of the figures, while the terms " lower "," bottom "and the like correspond to an axial direction of opposite direction. Thus, within the single-control cartridge 1, the single-control module 200 is arranged above the base module 100. It is the same for the sequential 300 and dual control 400 modules respectively in the sequential cartridges 2 and 2 bicommande.
    As clearly visible in Figures 2 and 3, the base module 100 includes a base 110 having a generally cylindrical outer shape, centered on the X-X axis. In the embodiment considered here, the base 110 mainly comprises two distinct parts, which are arranged one above the other along the axis XX, namely an upper part 111 and a lower part 112. These parts 111 and 112 are axially superimposed in a fixed manner on one another, forming between them a junction interface which extends transversely to the axis XX. This junction interface is sealed in the sense that the material contact areas between the upper portions 111 and lower 112 are sealed, prohibiting the passage of fluid through these contact areas. In practice, one possibility to achieve the sealing of the interface is to report a flat seal, sandwiched axially between the parts 111 and 112. Another solution, which limits the bulk of the base 110 in the direction of the XX axis, is that this sealing is achieved by a material connection between the parts 111 and 112, in particular by glue or, preferably, by a weld, for example obtained by laser welding.
    As shown in FIG. 1 and as clearly visible in FIGS. 2 and 3, the base 110 is provided with a channel 113 for circulating hot water between its lower face 11A and its upper face 110B, this channel 113 being delimited by, successively, the parts 111 and 112 and passing through the junction interface between these parts. Similarly, the base 110 is provided with a channel 114 for circulating hot water between its faces 11A and 110B, this channel 114 being delimited by, successively, the upper parts 111 and lower 112 and passing through the interface of FIG. junction between its parts.
    As clearly visible in Figures 2 and 3, the base 110 contains a chamber 115 which is traversed by the axis X-X. In the exemplary embodiment considered in the figures, this chamber 115 is centered on the axis XX and consists of internal free volumes, respectively delimited by the upper parts 111 and lower 112, the chamber 115 extending from both sides. other of the junction interface between these parts 111 and 112.
    On both sides and in a manner distinct from the chamber 115, the base 110 is provided with a cold water inlet 116 and a hot water inlet 117, which at their upper end open each on the upper face 110A of the base 110 while at their lower end, these inlets 116 and 117 open into the chamber 115, the lower end of the inlet 117 being situated axially lower than that of the inlet 116 , as shown in Figure 2. Thus, the inputs 116 and 117 connect the chamber 115 to the outside of the base 110, specifically to the upper face 11 OA of this base. In the exemplary embodiment considered in the figures, the inlets 116 and 117 are delimited exclusively by the upper part 111. The base 110 is also provided with a mixing outlet 118 which, at its upper end, opens into the while at its lower end, this outlet 118 opens onto the lower face 110B of the base 110. The outlet 118 thus connects the chamber 115 to the outside of the base 110, more precisely to the lower face 110B of the latter. In the exemplary embodiment considered in the figures, the outlet 118 is delimited exclusively by the lower part 112, being substantially centered on the axis X-X, as clearly visible in FIG.
    In use, in particular when the base module 100 is assembled to any of the specific modules 200, 300 and 400, the circulation channels 113 and 114 are designed to be fed respectively with cold water and hot water, since the 110B lower face of the base 110, as indicated by the arrows F1 and C1 in Figure 3. After leaving the base 110 by its upper face 110A, and, as discussed in more detail later, after circulating to inside the specific module 200, 300 or 400 to which the base module 100 is assembled, this cold water and this hot water are returned, from the aforementioned specific module, to the upper surface 11 OA of the base 110 so as to respectively feed the inputs 116 and 117, as indicated by the arrows F2 and C2 in Figure 2. This cold water and hot water, flowing down respectively in the entries 116 117, then feed the chamber. 115, in which they are mixed in the form of a mixed water, hereinafter referred to as a mixture, which, as indicated by the arrows M in FIG. 2, emerges from the chamber 115 through the outlet 118, being evacuated towards the low.
    The base module 100 also includes a slide 120 which, as clearly visible in FIGS. 2 and 3, has a generally tubular shape, centered on an axis which, in the assembled state of the base module 100, is parallel or even coincident with the XX axis.
    The slide 120 is mounted on the base 110, more precisely inside the chamber 115 of the latter, movably parallel to the axis XX between two extreme positions, namely: an extreme high position, in which the upper face of the slide 120 is in abutment against a high seat, which is fixed relative to the base 110 and which is for example defined by the upper part 111 of the base, and - an extreme low position, in which the lower face of the slide 120 is in abutment against a low seat, which is fixed relative to the base 110 and which is, for example, delimited by the lower part 112 of this base.
    The total axial dimension of the slide 120, separating one from the other its upper and lower faces, is smaller than the axial distance separating the above-mentioned high and low seats from each other. Also, when the drawer 120 is in its extreme low position, the drawer closes a hot water inlet inside the chamber 115, by pressing the drawer against the low seat, while opening at most a water passage cold F3, which is defined axially between the drawer and the high seat and which lets cold water from the inlet 116 to the chamber 115. Conversely, when the drawer is in its extreme high position, the drawer 120 closes an intake of cold water inside the chamber 115, by axial support of the drawer against the high seat, while opening at most a passage of hot water C3, which is defined axially between the drawer and the low seat and which passes the hot water from the inlet 117 to the chamber 115. In use, the passage F3 is fed with cold water through the inlet 116 and the passage C3 is fed with hot water through the inlet 117: according to the axial position of the slide 120 between its extreme positions high e and low, the respective flow sections of the cold water passage F3 and the hot water passage C3 vary inversely, which is to say that the amounts of cold water and hot water admitted in the chamber 115 are regulated, in respective inverse proportions, by the slide 120 according to its axial position. In Figures 2 and 3, the slide 120 occupies an axial position intermediate between its extreme high and low positions.
    In practice, to ensure the guiding of the movable assembly of the slide 120 in the chamber 115, the lateral face of this slide is received tightly and tightly within a complementary surface of the chamber 115, with the interposition of a seal to prevent mixing between cold water and hot water upstream of the drawer. In addition, so that the cold water admitted into the chamber 115 from the inlet 116 can join and mix with the hot water admitted inside this chamber from the inlet 117, then forming the aforementioned mixture s flowing, downstream of the spool, to the outlet 118, the spool 120 internally delimits one or more flow passages, which connect to each other its upper and lower faces and some of which are visible in the figure 3. The embodiment of the arrangements described in this paragraph is not limiting of the invention.
    To drive the slide 120 in axial displacement and thus to control its axial position, the base module 100 also comprises a thermostatic element 130 comprising a body 131 and a piston 132. The body 131 contains a heat-expandable material 133 which, by expansion, causes the relative displacement in translation of the piston 132. The body 131 and the piston 132 are centered on the corresponding translation axis, this translation axis being parallel or even coincident with the axis XX in the assembled state of the base 110. Also in the assembled state of the base 110, the body 131 is fixedly secured to the slide 120, and this by any appropriate means, so that at least a portion of the body 131 is disposed in the chamber 115 and the thermally expandable material 133 may be sensitized by the heat of the mixture flowing downstream of the slide 120 along the body 131. The thermostatic element 130 is also associated with a compressed spring 134 which acts on the body 131 of the thermostatic element 130, and therefore on the slide 120 secured to the body 131, in opposition to the deployment of the piston 132 out of the body 131, resulting from an expansion of the thermally expandable material 133. The return spring 134 is axially interposed between the base 110 and the slide 120, more precisely, in the embodiment considered here, between the lower part 112 of the base and the body 131 of the thermostatic element. during a contraction of the thermally expandable material 133, the spring 134 partially relaxes and recalls the piston 132 inside the body 131.
    As shown in FIGS. 1, 4 and 5, the specific single-controller module 200 includes a housing 210 having a generally cylindrical outer shape, centered on a geometric axis which, when the module 200 is assembled to the base module 100, is substantially confused with the XX axis. Whatever its embodiment, the housing 210 is designed to be fixedly secured to the base 110 of the base module 100, the housing 210 and the base 110 being shown not fixed to each other in the figure 1, while they are fixed to each other in Figures 4 and 5. The respective arrangements of the housing 210 and the base 110, allowing their relative fixing, are not limiting of the invention: in the embodiment considered in the figures, these respective arrangements cooperate by complementarity of shapes, including interlocking, clipping, adjustment, etc. Whatever the embodiment of these arrangements, the latter are adapted, by design, to position in a predetermined manner the module 200 relative to the base 110, in particular with respect to the axis XX, both in the direction of this axis transversely to this axis and angularly around this axis. In other words, once the housing 210 is fixed to the base 110, that is to say in the assembled state of the single-control cartridge 1, the single-control module 200 occupies a relative position vis-à-vis the base module 100 which is predetermined to ensure the overall operation of the cartridge 1.
    As clearly visible in FIGS. 4 and 5, the single-control module 200 includes an adjustment member 220 arranged inside the housing 210. When the base 110 and the housing 210 are assembled together, this device 220 allows, inside the housing 210, firstly to channel to the inlet 116 the cold water leaving the channel 113 and, secondly, to channel to the inlet 117 the hot water leaving the channel 114 while controllably controlling the flow of cold water sent to the inlet 116 and the flow of hot water sent to the inlet 117. In the embodiment considered on the FIGS., the adjusting member 220 consists of superimposed ceramic disks, namely a lower disk 221, which is fixed relative to the housing 210, and intermediate disks 222 and upper 223, which are secured to one another. other and which, compared to the housing 210, are both m rotatable about the axis XX and in translation in a geometrical plane perpendicular to this axis: as clearly visible in FIG. 4, the lower disk 221 is traversed by climbs and descents, respectively for hot water and water. cold water, while the lower face of the intermediate disk 222 is hollowed to communicate the climbs and the descents of cold water and to communicate the climbs and descents of hot water, so that by changing the relative positioning of the disks 221 and 222, the flow of cold water and the flow of hot water leaving the disk 221 are varied in a controlled manner. Other embodiments, that the assembly constituted by discs 221, 222 and 223 are conceivable for the adjusting member 220; for example, WO 2010/072966 proposes an alternative embodiment. More generally, any form of adjustment member, whether disk or other elements, can be used in the single-control module 200, as long as this adjustment member is mounted in the housing 210 at least partially mobile for, in the assembled state of the cartridge 1, varying the flow of cold water sent to the inlet 116 of the base 110 of the base module 100 and the flow of hot water sent to the inlet 117 of this base.
    The single control module 200 further includes a control mechanism 230 which, when this module 200 is assembled to the base module 100, makes it possible to jointly control the flow and the temperature of the mixture leaving the base 110 through the outlet 118.
    As clearly visible in FIGS. 1, 4 and 5, the control mechanism 230 comprises a lever 231: by driving the lever 231 by a user of the cartridge 1, the flow rate and the temperature of the mixture coming out of this cartridge are ordered in a systematically joint manner. To do this, the handle 231 is mounted relative to the housing 210 movably both in rotation about the X-X axis and tilting about an axis Z-Z extending perpendicularly to the axis X-X. In the exemplary embodiment considered in FIGS. 4 and 5, the handle 231 has a fork shape facing downwards, the two lower arms of which are mounted on a nut 232 of the control mechanism 230, this nut being arranged at inside the housing 210 being movable in rotation about the axis XX with respect to this housing. The mounting of the handle 231 on the nut 232 is designed to link in rotation about the axis XX the handle 231 and the nut 232, while allowing the tilting of the handle 231 relative to the nut 232 around the ZZ axis. By tilting the lever 231 around the axis ZZ, this lever moves the adjustment member 220 relative to the housing 210 so as to change the flow rate of the mixture consisting of cold water and hot water sent by this regulator 220 respectively at the inlet 116 and at the inlet 117, without significantly modifying the respective proportions of the cold water and the hot water in this mixture: in the exemplary embodiment considered in the figures , the lower end of the arms of the fork formed by the handle 231 is in mechanical engagement with the upper disc 223 so that the tilting of the handle 231 around the axis ZZ causes a translation of the upper disc 223 and, par- there, the intermediate disk 222 relative to the lower disk 221. Moreover, by rotating the lever 231 about the axis XX, this lever causes, according to a corresponding rotary movement, the 232, the handle and / or the nut then actuating by actuating the adjustment member 220 so as to increase one of the flow rates of cold water and hot water respectively sent to the inputs 116 and 117 by this organ 220, relative to the other of these flow rates: in the embodiment considered in the figures, the rotation of the handle 231 causes the corresponding rotation of the upper disk 223 and, therefore, the intermediate disk 222 relative to the lower disk 221.
    Of course, in particular according to the embodiment of the adjusting member 220, other embodiments than that described hitherto are conceivable for the part of the control mechanism 230, for actuating by drive this body adjustment.
    Furthermore, in order to drive the piston 132 of the thermostatic element 130 of the base module 100, when this basic module and the single-control module 200 are assembled together, the control mechanism 230 comprises a screw 233 which is screwed coaxially inside the nut 232, as clearly visible in FIGS. 4 and 5. The nut 232 and the screw 233 together form a "screw-nut" system which mechanically transforms a movement rotating around the axis XX of one of two in a translational movement along this axis of the other, provided that the latter is locked in rotation about the axis XX. In the assembled state of the single-control module 200, it is the screw 233 which is connected to the housing 210 in rotation about the axis XX: it is understood that an action of rotation about the axis XX of the nut 232 relative to the housing 210 causes a translation of the screw 233 along the axis XX. In addition, in order to transmit this translational movement to the piston 132 of the thermostatic element 130 when the single-control module 200 is assembled to the base module 100, the mechanism 230 also comprises a rod 234 which, in the assembled state of the cartridge monocontrol 1, is centered on the axis XX and connects the screw 233 to the piston 132 of the thermostatic element 130 so as to axially move the piston 132 by driving by this screw. As can be seen in FIGS. 4 and 5, the rod 234 extends in the upwardly axial extension of the piston 132 so that, on the one hand, under the upward pushing effect of the return spring 134, the piston 132 is supported axially against the lower end of the rod 234 and, secondly, under normal operating conditions of the cartridge 1, the upper end of the rod 234 is rigidly connected to the screw 233. It is understood that In normal operating conditions, the screw 233 and the rod 234 determine the axial altitude of the piston 132 with respect to the housing 210, independently of the relative position of this piston 132 with respect to the body 131 of the thermostatic element. 130.
    Thus, when the handle 231 is rotated about the axis XX, the corresponding rotation of the nut 232 causes, in addition to the displacement of the adjustment member 220 explained above, the translation along the axis XX of the screw 233, the rod 234 and the piston 132. In practice, the pitch of the screw-nut system formed by the nut 232 and the screw 233 is adapted to allow both the adjustment of the temperature of the mixture by the adjusting member 220 and the corrective regulation of this temperature by the slide 120 controlled in position by the thermostatic element 130, so as to impose on the mixture a desired target temperature, which is for example identified by a graduated ring, not visible in the figures, reported on the outer face of the housing 210. In other words, this setpoint temperature, which is defined by the axial position of the piston 132 controlled by the screw 233 and the rod 234, corresponds to a regulating position for the tray 120 inside the chamber 115, this position control is controlled by the thermostatic element 130.
    As explained hitherto, the mechanism 230 is therefore designed to, in the assembled state of the single-control cartridge 1, jointly control the flow and temperature of the mixture exiting the cartridge by exclusive drive of the single controller 231 provided to operate by driving the adjusting member 220 and the piston 132 of the thermostatic element 130 permanently with each other.
    According to an advantageous optional arrangement, which is implemented for the single-control module 200 considered in FIGS. 4 and 5, the control mechanism 230 also comprises an overtravel spring 235 which, in the assembled state of the single-control module 200, is interposed , being compressed, axially between the screw 233 and the rod 234. This overtravel spring 235 has a stiffness greater than that of the return spring 134, typically a stiffness twice that of the return spring 134, so that the assembled state of the single-control cartridge 1, as long as the latter is in normal operating conditions, that is to say as long as the slide 120 is movable inside the chamber 115 freely, that is to say without abutment axially against a resistant surface, the overtravel spring 235 rigidly transmits the axial forces between the rod 234 and the screw 233, whereas, in case of overtravel of the piston 132 while the slide 120 b axially against a resistant surface preventing it from accommodating this overtravel of the piston, the overtravel spring 235 takes care of accommodating the overtravel of the piston 132, by compressing itself further under the action of the rod 234, which itself is driven axially by the piston 132. In this way, it avoids damaging the slide 120 and / or the thermostatic element 130, typically when the body 131 of the latter is sensitized by a mixture having a temperature too high, as it is the case when the cold water supplying the cartridge is cut significantly or even completely, ie outside the normal operating conditions for this cartridge. Vis-à-vis the user, the overtravel spring 235 gives the single-control cartridge 1 a safety function against burns.
    In the embodiment considered in FIGS. 4 and 5, the overtravel spring 235 is advantageously housed inside the screw 233, being compressed between an internal shoulder of this screw and a bushing 236 making it possible to finely adjust the angular indexing about the axis XX of the handle 231 vis-à-vis the set temperature for the thermostatic regulation by the slide 120. This sleeve 236 is screwed to the upper end of the rod 234, while being mounted relative to the screw 233, in particular inside the latter, so as to both be rotatably connected to this screw 233 around the axis XX and be movable relative to the screw 233 along of this axis XX. It is understood that, in the assembled state of the single-control cartridge 1 and while the handle 231 is held fixed in rotation about the axis XX relative to the housing 210, the screw-nut system formed by the nut 232 and the screw 233 is immobilized, while leaving the possibility of modifying the axial position of the rod 234 and therefore that of the thermostatic element 130, by rotating on itself about the axis XX of the rod 234 relative to at the sleeve 236 held fixed in rotation by the screw 233, in other words by screwing-unscrewing the rod 234 inside the sleeve 236. Thus, for a given angular position of the handle 231 relative to the housing 210, typically for an angular position of this handle which is associated in a predetermined manner with a predetermined value of the set temperature, the rotation of the rod 234 inside the bush 236 modifies the axial altitude of the udder 132 of the thermostatic element 130, which allows to finely adjust the axial altitude of the piston. In practice, this fine adjustment is performed on a dedicated bench or similar installation, through which is circulated through the cartridge water having a known temperature imposed, which is used as a temperature reference to adjust the position of the thermostatic element 130 along the axis XX.
    As mentioned above, the single-control cartridge 1 is manufactured by assembling the base module 100 and the specific single-controller module 200 with each other, underlining that, as shown in FIG. 1, the base module 100 is pre-assembled. independent of the single control module 200 and this single-control module 200 is preassembled independently of the base module 100. In other words, the base module 100 is obtained by the assembly between them of the base 110, the drawer 120 and of the thermostatic element 130, independently of obtaining the single-control module 200 by assembling together the housing 210, the adjusting member 220 and the control mechanism 230. To obtain the single-control cartridge 1, the module of base 100, in the preassembled state, and the single-control module 200, in the preassembled state, are subsequently assembled with each other, by means of fixing the base 110 and the housing 21 0 to one another, this fixing leading to a functional arrangement of the slide 120, the thermostatic element 130, the adjusting member 220 and the control mechanism 230 relative to each other as in FIGS. and 5.
    With regard to the sequential specific module 300, shown in FIGS. 6 and 7 in its assembled state with the base module 100 to form the sequential cartridge 2, this module 300 comprises, in a manner similar to the single-control module 200, a housing 310 , an adjusting member 320 and a control mechanism 330. Before detailing this housing 310, this adjustment member 320 and this control mechanism 330, it will be noted that the sequential module 300 differs from the other specific modules 200 and 400 by the how this module 300 controls the flow and the temperature of the mixture leaving the base module 100 when the latter is assembled to the module 300: in fact, the sequential module 300 is provided to successively control the flow rate and the temperature of this mixture, as explained later.
    More specifically, the housing 310 is functionally similar to the housing 210, in the sense that the housing 310 is adapted to attach to the base 110 of the base module 100 for the purposes of assembly between the modules 100 and 300. In particular , the housing 310 has arrangements that are functionally or even structurally similar to those of the housing 210, allowing the attachment of the module 310 to the base 110 with a relative positioning between the modules 100 and 300 predetermined. On the other hand, because of the specificity of the module 300 compared to the other specific modules 200 and 400, the housing 310 has a specific part, which is distinguished from the corresponding part of the housing 210. The adjustment member 320 is functionally similar to the adjusting member 220, in the sense that the adjusting member 320 is mounted in the housing 310 in a manner that is at least partly movable so as to, in the assembled state of the sequential cartridge 2, vary the flow of water cold, sent to the inlet 116 by the adjusting member 220, and the flow of hot water, sent to the inlet 117 by the adjusting member 220. This being because of the specificity of the module 300 compared the other specific modules 200 and 400, the adjustment member 320 is structurally different from the adjustment member 220. Thus, in the example shown in Figures 6 and 7, the adjustment member 320 comprises a set of two superimposed disks, namely a lower disk 321, which is fixedly mounted relative to the housing 310, and an upper disk 322, which is mounted exclusively to rotate about the X-X axis relative to the lower disk 321.
    As for the control mechanism 330, it lacks a joystick, which would be similar to the joystick 231, in favor of a single ring 331 which is mounted relative to the housing 310 exclusively in rotation about the axis X-X. This ring 331 is connected in rotation to a nut 332 of the mechanism 330, inside which is screwed a screw 333 rotatably connected about the axis XX to the housing 310. In a similar manner to the screw 233, the screw 333 is , in the assembled state of the sequential cartridge 2, connected to the piston 132 of the thermostatic element 130 by a rod 334, with the interposition of an overtravel spring 335 mounted axially between the screw 333 and a fine adjustment bushing 336, functionally similar to the bushing 236. The spring 335 differs from the spring 235 in that it does not ensure a rigid transmission of movement between the screw 333 and the rod 334 over the entire travel of this screw 333, in other words over the entire rotational stroke of the nut 332 and the ring 331 rotatably connected thereto. More specifically, on a first portion of the rotary stroke of the ring 331, corresponding to the rotary drive of this ring between an extreme position, associated with the complete closure of the inlet of cold water and hot water in the inputs 116 and 117 of the base 110, and an intermediate position, between which the ring 331 controls, through the nut 332, the adjustment member 320 so that the latter maintains the zero flow of hot water sent to the inlet 117 while varying only the flow of cold water sent to the inlet 116 to a maximum of this flow of cold water when the ring 331 occupies the intermediate position mentioned above, the spring 335 does not transmit not the translational movement of the screw 333 to the stem 334, accommodating this translational movement by means of its compression; then, on a second part of the rotary stroke of the ring 331, corresponding to the drive of this ring beyond the aforementioned intermediate position, the ring 331 controls, via the nut 332, the member 320 for the latter to vary both the flow of cold water sent to the inlet 116 and the flow of hot water to the inlet 117 while, at the same time, the spring 335 transmits rigidly the translational movement of the screw 333 to the rod 334. The position of the ring 331 beyond the aforementioned intermediate position thus controls the temperature of the mixture leaving the sequential cartridge 2, by the adjustment of this temperature by the control member. control 320 and corrective regulation of this temperature by the slide 120 controlled in position by the thermostatic element 130, so as to impose the mixture a desired temperature, which is for example identified by a graduated lamb, not visible in the figures, attached to the outer face of the housing 310. Thus, the control mechanism 330 of the sequential module 300 is adapted to successively control the flow and temperature of the mixture by exclusive drive of the single ring 331 provided to first actuate the adjusting member 220 without driving the piston 132 of the thermostatic element 130, then to actuate the adjusting member 320 and the piston 132 with each other.
    According to considerations similar to those explained above for the modules 100 and 200, the sequential specific module 300 is preassembled independently of the base module 100, before being, while its housing 310, its adjustment member 320 and its control mechanism 330 are already preassembled to each other, assembled to the base module 100, itself preassembled, in order to obtain the sequential cartridge 2.
    The dual control module 400 has, for its part, the power specificity, when assembled to the base module 100, to separately control the flow rate and the temperature of the mixture leaving the dual control cartridge 3.
    The dual-control module 400 includes a housing 410 and a regulator 420 which are functionally similar, or in part structurally similar to the housings 210 or 310 and the regulator 220 or 320, while having specificities related to the capacitance of the module 400 to separately control the flow and the temperature of the mixture.
    Similarly, the dual control module 400 includes a control mechanism 430 which, instead of having a single handle such as the handle 231 or a single ring such as the ring 331, has two separate rings 431 and 437, which are each mounted relative to the housing 410 in a mobile manner exclusively in rotation about the axis XX. The ring 431 is rotatably connected about the axis XX to a screw 433 of the mechanism 430, screwed inside a nut 432 of this mechanism 430, this nut 432 being connected to the casing 410 both in rotation around of the axis XX and in translation along this axis: the drive in rotation of the ring 431 drives the screwing-unscrewing of the screw 433 about the axis XX relative to the casing 410. This screwing-unscrewing is transmitted to a rod 434, screwed fixed inside the screw 433: similarly to the rods 234 and 334, the rod 434 connects the screw 433 to the piston 132 of the thermostatic element 130 so as to axially move the piston by driving by the screw. For its part, the ring 437 is rotatably connected to the adjusting member 420, in particular to a movable portion thereof relative to the casing 410, so that the rotary drive of the ring 437 actuates the drive. adjusting member 420 for the latter to vary the flow rates of cold water and hot water respectively sent to the inlet 116 and the inlet 117 without substantially changing the relative proportions of cold water and water hot. The mechanism 430 provides the mechanical independence between the rings 431 and 437, so that this mechanism 430 separately controls the flow of the mixture exiting the dual control cartridge 3, by exclusive drive of its ring 437 provided to operate by drive only l adjusting member 220, and the temperature of this mixture by exclusive drive of the ring 431 provided to actuate by driving only the piston 132 of the thermostatic element 130.
    Advantageously, the mechanism 430 of the dual-control module 400 integrates an overtravel spring 435 and a bushing 436, functionally or even structurally similar to the overtravel spring 235 and to the bushing 236 of the control mechanism 230.
    Again, according to considerations similar to those presented above, the dual control module 400 is preassembled independently to the base module 100: while its housing 410, its controller 420 and its control mechanism 430 are already pre-assembled together. to the others, the module 400 is assembled to the base module 100, itself preassembled, in order to obtain the dual control cartridge 3.
    By disposing of the manufacturing assembly shown in FIG. 1, it is therefore possible to obtain either the single-control cartridge 1 by assembly of the base module 100 with the specific single-control module 200, or the sequential cartridge 2 by assembly of the module. base 100 with the sequential specific module 300, ie the dual control cartridge 3 by assembling the base module 100 with the specific module 400, in other words, this manufacturing unit is provided so that the preassembled base module 100 can be assembled indifferently to any of the specific modules 200, 300 and 400, depending on whether the manufacturing need is to obtain the single-control cartridge 1, the sequential cartridge 2 or the dual-control cartridge 3. As explained in detail in the introductory part of this document, technical and financial investments are thus less than those that would be necessary to obtain dissociated cartridges 1,2 and 3.
    Of course, as an alternative, rather than the manufacturing set includes the three specific modules 200, 300 and 400, only two of these specific modules can be provided within the manufacturing group.
    According to a particularly advantageous aspect, which is implemented in the exemplary embodiment considered in the figures, certain components of the specific modules 200, 300 and 400 are provided structurally identical between these specific modules. This is particularly the case for the screws 233, 333 and 433 and for the rods 234, 334 and 434. By sharing in this way structurally identical individual components, the specific modules 200, 300 and 400 may be less expensive to manufacture.
    Finally, various arrangements and variants are also possible to the assembly of manufacture described so far. As examples: - within the base module 100, rather than moving the slide 120 inside the chamber 115 by the thermostatic element 130, the latter can be replaced by a shape memory element in temperature function, in particular a shape memory spring; more generally, such a shape memory element and the thermostatic element 130 are only possible embodiments for a thermostatic actuator which provides the function of displacement of the slide 120 inside the chamber 115 as a function of the temperature and whose dedicated part defines, by its axial position, the set temperature at which the spool regulates the temperature of the mixture; and / or - also within the base module 100, rather than making the base 110 in two parts such as the parts 111 and 112 detailed above, the base 110 may, alternatively not shown, be carried out differently, for example in one piece, or as in WO 2014/135614.
