Abstract

In a waveguide twist having a torsion element with at least three individual parts situated adjacent to each other and rotatable around an axis of the torsion element, in which each of the individual parts has a central passage hole with a cross-section corresponding to the open cross-section of the waveguides, and in which the passage holes of the individual parts in a non-rotated condition of the torsion element are aligned with each other, a recess is formed in one face of each of the individual parts, the extent of the recess in circumferential direction corresponding to a specified angle of rotation; from the other face of the individual parts a pin extends in an axial direction; and in a mounted position of the torsion element a pin projecting from one individual part engages in the recess located in the face of the adjacent individual part.
