Abstract (en)

[origin: EP2202774A1] The transition has a tubular body (78) whose end (90) in a shape of a cylindrical tube including a conical internal propagation surface (130) and another end (80) in a shape of a rectangular tube including a large side (84), another large side, a small side (86) and another small side. A passage (79) has a set of flat internal propagation surfaces parallel to the large sides and another set of flat internal propagation surfaces parallel to the small sides. The former set is connected to the conical surface by respective curved connection surfaces (132, 133) with bidirectional curvature radii.
