- the openings can be made in selected locations of the manifold 16, in particular in a chosen angular position (see the angle ⁇ 1 of Figure 2) relative to the YY axis of the manifold 16.
- the angle ⁇ 1 can vary from 0 to 180 °.
- tubes 34 and 36 can be arranged in a non-radial position relative to the axis of the housing axial 62 to tilt the cartridge more or less relative to to the YY axis, as shown by the angle ⁇ 2 in Figure 2.
- the angle ⁇ 2 can vary between 0 and 90 ° by compared to the generators of the manifold.
- Cartridge 28 contains only refrigerant condensed at low temperature and compensates for variations in the volume of the refrigerant in the circuit, while dehydrating the refrigerant.
- cartridge 28 needs to be replaced, just proceed when it is unscrewed by actuating its head 44, which can be by example produced in the form of a hexagon head, then replace it with a new cartridge.
- the cartridge 28 is strictly identical to the cartridge 28 of FIG. 1.
- the base 30 comprises a cylindrical body 80 in which are formed the axial housing 62 and the housing ring finger 64.
