  • the axial offset of the stop ends of the windows 221 can be achieved by varying either the slope degree of the window section slopes or the slope lengths of the window sections. It is also possible to envisage a combination of different lengths and degrees of inclination. However, it is not excluded according to the invention that the stop ends of the windows are arranged in the same plane. However, the offset of these ends is preferred.
  • slopes 2215 and 2216 each form a recess 2217 and 2218 which breaks the linearity of the slope.
  • These recesses, notches or bearings define intermediate positions between the low point 2210 and the abutment ends 2213 and 2214.
  • the base 1 forms around the ring 22 a complex configuration that is not regular around the perimeter of the crown.
  • the base forms two buttresses 24 interrupted on the one hand by a lower slot 25 and on the other by a range 26.
  • the slot 25 is located below the buttresses 24 and the beach 26 is also located. 25 against the buttresses 25, at a height even lower than that of the slot 25.
