  • the rotation of the wheel 334 and the absence of rotation of the counter-ring 360 makes it possible to close the housing 310 in a similar way as described above with regard to the Figures 1 to 14 .
  • the axial displacement of the valve 329 moves in the passage 305 the inlet of the water supply pipe and the outlet 321 of the water return pipe 316 so as to position the inlet of the water intake pipe and the outlet 321 of the water return pipe 316 between the first seal 114 and the second gasket 118 in axial projection, that is to say in the passage 305 of water flow.
  • This positioning of the inlet of the water supply pipe and the outlet 321 of the water return pipe 316 releases these pipes and allows the supply of water flow to the housing 310 as explained with regard to Figures 1 to 14 .
  • the axial displacement of the valve 329 brings firstly the upper face 125 of the valve 329 in contact with the lower face 133 of the plate 345. Therefore, the needles 128 are no longer retracted by the plate 345 and through the orifices 144 and protruding from the upper face of the plate 345.
  • the projection of the needles 128 makes it possible to tear a capsule seal located in the housing, as described opposite Figures 1 to 14 and thus to release the product contained in said capsule.
  • the axial displacement of the valve 329 pushes the plate 345 towards the wheel 334.
  • This displacement of the plate 345 brings the bearing surface 347 closer to the wheel 334 and makes it possible to grip the collar of a capsule between the surface 347 formed by the seal 142 carried by the plate 345 and the lower faces 382 and 383 respectively of the wheel 334 and the counter-ring 360.
  • the clasping of the collar of the capsule is made in a manner similar to that described with regard to the Figures 1 to 14 .
  • the tightness in the housing is provided on the one hand by the seal 143 located on the lower face 133 of the plate 345 and, on the other hand, by the clasping of the collar of the capsule by the seal 142 forming the surface of the 347 and the lower faces 382 and 383 respectively of the wheel 334 and against the ring 360.
  • valve 329 has a freedom in axial displacement of 5.5 mm and the plate 345 has a freedom in axial displacement of 1 mm.
  • abutment sections 137 cooperate with the underside 150 so as to move the plate 345 away from the wheel and release the flange of the capsule in the housing.
  • This rotation of the wheel 334 also causes the opening of the housing 310 for capsule as described above with regard to Figures 1 to 14 .
  • a visual cue is located on the outer face of the wheel 334 to indicate the location of the pin 148.
  • a visual cue located on the outer face of the base 303. These pins can locate the extreme positions of the pin 148 in the groove 108.

  • Such pin 123 of particular shape and its complementary housing 151 ensure that the mounting of the wheel 334 is performed correctly.
  • the same system is applicable in the context of the lugs 139 of the complementary plate of the housing 145 of the counter ring.
  • the needles 128 may be inserts or directly integrated in the upper part 329A of the valve 329.
  • the water supply and return water pipes through the valve may be constituted in any suitable manner, for example being located only in the upper portion 329B of the valve 329.
  • the embodiments described above have the inlet of the water supply pipe and the outlet of the water return pipe in the axis respectively of the inlet and the outlet of the passage of the base.
  • the orientation of the inlet of the water supply pipe and the outlet of the water return pipe may be different.
  • a change of orientation and position of the inlet of the water supply pipe and / or the outlet of the water return pipe makes it possible in particular to regulate the flow rate of the flows flowing in the supply pipes of water and back water.
  • the inlet of the water supply pipe and the outlet of the water return pipe can lead to the outer face of the valve in different radial planes but be oriented so that the supply pipes of Water and water return are located in the same radial plane.
  • the orientation of the inlet 317 of the water supply pipe 315 and the orientation of the outlet 321 of the water return pipe 316 are such that said water inlet pipes 315 and return pipe Water 316 are located in the plane of symmetry P of the pedestal 303.
  • the inlet of the water supply pipe is located upstream of the passage of the base and the outlet of the water return pipe is located downstream of said passage.
  • the position of the inlet of the water supply pipe and the position of the outlet of the water return pipe can be reversed.
