- the invention makes it possible in particular to centralize different thermal management components in a single assembly, so as to optimize the vehicle's footprint, reduce the cost and facilitate its integration.
- These different components belong to one of the first sub-assembly and second sub-assembly which, in the state of the art, are usually presented as separate parts which must be handled separately and which require complex fluidic connections and bulky, for example using additional pipes for the different heat transfer fluids.
- the invention makes it possible to do without this type of additional pipes.

- the intermediate shaft 312 is aligned with the axis Xv .
- the intermediate shaft 312 is rotatably arranged through the necks 148 and 248, as can be clearly seen in Figure 10.
- the two-stage distributor member 310 is made in one piece, for example in plastic.
- the distributor member 310 comprises a drive shaft 31 1 meshing with the actuator 57.
- the distributor member 310 can be rotated by the actuator 57 so that the stages 54 and 55 of the valve 45 can take different distribution positions, to ensure different flow paths respectively for the first heat transfer fluid and the second heat transfer fluid. These different flow paths can be configured in different ways, depending on the type of thermal management chosen.
