According to the invention, a protrusion (113, 114) is positioned at the centre of the front face of the internal piece, this protrusion being sized such that the free portion of same opposite the front face, said portion being referred to as the torpedo (114), penetrates into the outlet opening (123) so as to reduce the cross section of same and form an annular outlet port.
