- the first centering portion 11 and the second centering portion 21 are shaped so as to together form a means for centering the first part 10 and the second part 20 between them with a constant support of the first centering portion on the second portion. of centering.
- the unit 1 according to the present allows effective centering of the first and second parts between them.
- the unit 1 comprises an articulation in rotation around Z-Z of the third part 30 with respect to the first part 10 and/or the second part 20.
- the rotational articulation can in particular comprise shapes in correspondence of the second part and of the third room.
- the first part 10 and/or the second part 20 is configured so as to limit, directly or indirectly, the radial clearance of the third piece 30 perpendicular to the axis ZZ.
- the third part 30 is not in tight contact against the centering portions defining the axis ZZ, and this in order to be able to enter into rotation around said axis ZZ.
- the first part 10 or the second part 20 forms the joint in rotation around ZZ of the third part 30.
- the second centering portion 21 has a distal end 22 comprising a deformable centering means 23.
- the deformable centering means 23 is deformed so as to compensate for any radial clearance, perpendicular to the axis ZZ between the first part 10 and the second room 20.
- the deformable centering means 23 comprises deformable lugs 24 under the action of a pressure exerted by the first part 10, in particular by the first centering portion 11. These deformable pastes 24 are particularly visible in FIG. 1.
- the tabs 24 are radially deformable.
- the lugs 24 are deformed radially outwards and exert pressure against the first centering portion 11 so as to limit any radial play perpendicular to the Z-Z axis between the first part 10 and the second part 20 and thus improving the centering of the parts.
- the deformable tabs 24 have a reduced thickness compared to the rest of the second centering portion 21.
- the second centering portion 21 has a substantially cylindrical shape.

- the pin 12 when the pin 12 is housed in the second centering portion 21, said pin 12 is moved axially along the Z-Z axis in the direction of the second part 20, thus exerting a radial pressure against the deformable centering means 23 and in particular the deformable lugs 24.
- the free end of the lugs 24 is thus advantageously in contact with the pin 12, at the level of the base of the latter.
- the pin 12 has a cone angle greater than a relief angle.
- the pin 12 has a cone angle greater than 10°. Setting a minimum taper angle helps distinguish it from a draft angle. Indeed, such a relief angle is not sufficient to generate a constant support of the first centering portion 11 on the second centering portion 21 and thus obtain the desired centering effect.
- the pin 12 is advantageously substantially hollow.
- the pin 12 has a constant wall thickness.
- the second part 20 and the third part 30 are configured so as to limit any radial clearance perpendicular to the Z-Z axis between said second and third parts.

- one of said stops 13 comprises a ring 14 formed on the first part 10.
- the ring 14 and the conical pin 12 are concentric.
- the flexible lugs 24 are located between the ring 14 and the pin 12.
- another of said stops 13 comprises a third extra thickness of material 26 of the second part 20. This third extra thickness of material 26 is located at the level of the proximal end of the second centering portion 21.
- the third part 30 is sandwiched by the ring 14 of the first part 10 and by the second extra thickness of material 26 of the second part 20 so as to limit the axial displacement of the third part 30 along the Z-Z axis.

- PBT Polybutylene terephthalate
- POM polyacetal
- PA polyamide
- the invention also relates to a method of manufacturing an air conditioning unit as described above.
- the method according to the invention comprises a step (E1) of positioning the third part 30 on the second part 20.
