Abstract
Compression between two blocks (5, 6) forming a dynamic seal (13) between a rotor (2) and a stator (1) is applied by an inflatable seal (7) located in a groove. When blocks (5 and 6) must be cuttable, in other words divided into two parts to be assembled around the shaft (2), the originally linear seal (7) is wound in the groove and its ends are in contact with each other. It applies a uniform compression around the circumference and its placement does not require major disassembly of the equipment.
