Rotary machine for fluid with a radial seal clearance

摘要

A wear ring (5) is fastened to one of a stator unit (4) via an elastically deformable fastening unit (6). The fastening unit is connected to the stator unit on the one side. A radial gap (8) is formed between an outer jacket surface of the wear ring and the fastening unit. The fastening unit is connected on the other side to the wear ring. A radial gap (7) is being formed on the side between the outer jacket surface of the fastening unit and the stator unit.
