Abstract (en)
The turbomachine has two sub-assemblies assembled together. One of the assemblies has an outer case while the other assembly has a support for fixed vanes of the machine, where the case and the support define, between them, an annular chamber (18) within which a pressure seal (20) is inserted. An annular spacer (50) is inserted between a circular region of the former assembly and a circular end of a flat surface of the latter assembly.
