  • the flange is thus intermediate said ring portion 60 and said insert portion 45. Intermediate simply means somewhere between.
  • the insert ring 60 of the adaptor assembly includes a recessed raceway 62.
  • the ring also includes a flange 64 with cut-outs 66. The flange, in part, forms said raceway. The cutouts open into said raceway.
  • the first coupling portion 45, flange portion 54, and insert ring 60 have a seamless monoblock construction.
  • the internal member 49 partially disposed within said hollow 52, forms the filling orifice 32 of a filling channel 34. It further forms an exit 35 of the filling channel 34.
