SEAL PACKING ARRANGED BETWEEN TWO OPPOSITE ELEMENTS AND AROUND AN AXIS

摘要

The compression between two blocks (5, 6) establishing a dynamic seal (13) between a rotor (2) and a stator (1) is provided by an inflatable seal (7) housed in a groove. When the blocks (5 and 6) are intended to be sectile, that is to say divided into two parts in order to be assembled around the shaft (2), the seal (7), which at first is linear, is wound around in the groove and the ends thereof join up. Said seal provides uniform compression around the circumference and no longer requires any significant disassembly of the apparatus in order to be placed.
