These compensators consist of two accordions connected by a middle tube. The compensator is coupled with two (TD) or more (TM) coupling bolts mounted in spherical bearings.
The use of these compensators can compensate for large radial displacements in all planes, and in the variant with two coupling bolts, the angular displacements also. The advantage of using this type is the elimination of the need for robust solid points because the force due to the internal pressure is taken over by the coupling elements.
